Short answer: Unmarried couples can buy life insurance on each other, but the path runs through a step marriage skips automatically: showing insurable interest, a documented financial or dependency relationship, since the law does not presume it the way it presumes it for spouses. Once a policy is issued, it works exactly like any other policy. The bigger practical difference is what happens without planning: an unmarried partner has no automatic inheritance or beneficiary rights at all, which makes the beneficiary designation and a will the parts of this decision that genuinely cannot be skipped.
Most life insurance guidance is written with marriage as the unstated default. It assumes a beneficiary form that names a spouse will be understood without explanation. It assumes a surviving partner has some automatic legal standing if nothing was ever formally arranged. Neither assumption holds for an unmarried couple, and running the married playbook without adjusting for that gap is how a genuinely well-intentioned plan leaves a surviving partner with nothing.
This explainer covers the two questions that actually differ for an unmarried couple, insurable interest at the application stage and beneficiary designation afterward, then builds a coverage number using the same replacement-cost method used elsewhere on this site. Neither question is a reason to delay buying coverage; both are well understood by insurers and estate planning attorneys who work with unmarried couples regularly, and both are solvable with ordinary paperwork rather than anything exotic. If you are weighing whether a joint or individual policy fits your situation once the underwriting question is settled, our explainer on joint life insurance covers that product decision in full. Every dollar figure here is illustrative, so run your own numbers through the coverage calculator rather than adopting ours.
Key takeaways
- Insurable interest, not marital status, is the actual legal requirement for buying life insurance on someone else's life; marriage simply satisfies it automatically, while an unmarried couple has to show it.
- Most long-term, financially interdependent unmarried couples can demonstrate insurable interest without difficulty, commonly through a joint mortgage or lease, shared accounts, or a child in common.
- An unmarried partner has no automatic inheritance rights under most states' default rules, which makes a correctly completed beneficiary designation functionally more important than it is for a married couple.
- Two individual policies generally fit an unmarried couple better than one joint policy, for the same flexibility reasons they are usually recommended for married couples.
- An illustrative build for one partner earning $75,000, with a $280,000 shared mortgage and a 4 year old child in common, totals about $1,614,000, rounding to a $1,625,000 policy.
Why unmarried couples ask different questions than married ones
A married couple buying life insurance skips a step without ever noticing it is a step. The law presumes spouses have an insurable interest in each other, so the application process goes straight from deciding how much coverage to buy into the underwriting that any applicant goes through. An unmarried couple hits a question first: can this applicant actually buy a policy on this other person’s life at all, which is a real legal requirement called insurable interest, not a formality.
The good news is that this hurdle is lower than it sounds for most couples who have been together for any meaningful length of time and share any real financial life. The requirement exists to prevent life insurance from being used as a bet on a stranger’s death, not to exclude committed unmarried partners, and most insurers have straightforward, well-established ways to document that a long-term partner clears it.
It helps to separate the two things this piece is really about from the start, because they get easily conflated. Insurable interest is about whether you can buy the policy at all, decided once at application. Beneficiary designation is about where the money actually goes once a claim is paid, and it stays relevant for as long as the policy is in force. A couple can clear the first question easily and still get the second one wrong by never updating a form, which is exactly the mistake this piece spends the most time helping you avoid.
What insurable interest means, and why it is the first hurdle
Insurable interest is the legal principle that someone applying for a policy on another person’s life has to show they would genuinely suffer a financial loss if that person died. It exists for an obvious reason: without it, anyone could take out a large policy on anyone else, creating a financial incentive that has nothing to do with protecting a real relationship. Spouses, children, and business partners with a documented stake in each other all typically satisfy it. Marriage is simply the clearest, most automatic way the law recognizes the requirement is met.
An unmarried couple does not get that automatic presumption, which means the relationship has to be shown rather than assumed. This is worth separating clearly from the stigma the question can carry: insurable interest is not a judgment about whether a relationship is “real” or serious enough. It is a documentation requirement, and for most long-term, financially intertwined couples it is a straightforward one to clear.
How insurers evaluate insurable interest for an unmarried couple
Insurers generally look for evidence of financial interdependence or shared obligations rather than requiring a single specific document. A joint mortgage or lease, joint bank or credit accounts, a documented length of cohabitation, and a child the couple shares are all commonly accepted evidence, and most applicants clear the bar using whatever combination of these they actually have rather than needing every item on the list.
The underlying question an underwriter is really asking is simple: would this applicant’s life genuinely be worse off, financially, if the insured person died. A couple that has shared a home, a mortgage, and household finances for years answers that question clearly through the paperwork they already have. A newer relationship with no shared finances and no shared housing has less to point to, which can mean more questions at application or, in some cases, a smaller amount of coverage approved until the financial interdependence is more established.
The documentation that typically establishes it
In practice, the paperwork an unmarried couple already generates from ordinary shared life is usually what an insurer wants to see. A joint mortgage or a lease with both names on it is often the single clearest piece of evidence, because it is a formal, dated document showing a shared, substantial financial obligation. Joint bank accounts or credit accounts showing commingled finances work similarly. A shared child, documented through a birth certificate, is strong evidence on its own. A domestic partnership or civil union registration, where your state offers one, is useful documentary evidence too, though it is not available everywhere and is not required where it is not offered.
Gather what you already have before assuming you need something more formal. Most couples who have lived together for any real length of time already hold at least one or two of these documents without having created them specifically for this purpose.
It is worth preparing this paperwork before the application rather than scrambling for it once an underwriter asks, since the request can otherwise add a round trip to an already multi-step process. A simple folder with a recent mortgage or lease statement, a joint bank statement, and, if applicable, a child’s birth certificate covers most of what gets requested, and having it ready signals a straightforward case rather than inviting extra scrutiny.
Underwriting beyond insurable interest: the rest of the application is ordinary
It is worth being direct about what does not change for an unmarried couple, because the insurable interest question can make the whole process sound more complicated than it actually is. Once insurable interest is established, usually at the very start of the application through the documentation described above, the rest of the underwriting, health questions, tobacco use, family history, driving record, occupation, is identical to what any applicant answers regardless of relationship status. An unmarried partner is not priced differently, rated differently, or asked different medical questions because of their relationship status.
The insurable interest question is also typically resolved once, at application, rather than revisited periodically. A policy issued while a couple was unmarried does not need to be re-justified later if the relationship changes, the same way a married couple’s policy does not need to be re-justified if they later divorce. The requirement is about whether the applicant could legitimately buy the policy in the first place, not an ongoing condition of keeping it in force.
What happens without it: can you insure a partner you cannot show interest in
A couple that genuinely cannot document any financial interdependence, a very new relationship with separate finances and separate housing, for instance, may find an application more difficult to place, or may be offered a smaller amount of coverage than requested until the relationship develops the kind of documented interdependence described above. This is not a permanent closed door. It is a timing and documentation question, and reapplying once a joint lease, a shared account, or another year of the relationship exists is a normal and realistic path.
A licensed independent agent who has placed policies for unmarried couples before can be particularly useful here, since insurers genuinely differ in exactly how much documentation they require and how flexible they are about it, the same way they differ on health underwriting.
Naming your partner as beneficiary: the part that is actually simple
Once a policy is approved, naming your partner as beneficiary is no different from naming anyone else: a line on a form, with no special category or extra paperwork required because the beneficiary is unmarried to the policyholder. An adult can name any person they choose as beneficiary, and an unmarried partner is treated exactly the same as a spouse, a sibling, or a friend would be for this specific step. There is no insurable interest requirement on the beneficiary side the way there is on the application side; the person named simply receives the proceeds.
Where this gets consequential is not the naming itself, but what happens if it is never done, or never updated, which the next section covers directly.
Why there is no automatic claim without a beneficiary designation
This is the single most important practical difference between a married and an unmarried couple in this whole topic, and it deserves to be stated plainly. If a married person dies without specific estate planning in place, most states’ default inheritance rules generally recognize a surviving spouse automatically. If an unmarried person dies in the same circumstances, their partner typically has no automatic legal claim to anything, no matter how long the relationship lasted, how intertwined the finances were, or how the couple thought of themselves.
The same logic extends directly to a life insurance policy. A death benefit goes to whoever is named as beneficiary on the policy, full stop. If no beneficiary is named, or if a beneficiary form was never updated from an earlier relationship, or from a parent named years before the current relationship began, the proceeds follow the policy’s own default rules or the deceased’s estate, not the surviving partner, regardless of how obviously that partner was the intended recipient. For an unmarried couple, there is no backstop the way there sometimes is for a spouse. The form is the whole decision.
State law and domestic partnership status: what it does and does not change
Some states offer domestic partnership or civil union registration, which can grant specific legal protections, sometimes including elements of automatic inheritance, though the exact scope varies enormously by state and is narrower than marriage in most places that offer it. Where available, registering is useful both as insurable interest documentation and, depending on your specific state, for whatever protections that state grants registered partners.
Treat this as a patchwork, not a uniform rule. What a registration does in one state may not exist at all in another, and the trend over recent years has been toward fewer states actively expanding these options rather than more, as marriage has become the single path offering full automatic protection nationwide. Confirm your own state’s specific rules with an estate planning attorney rather than assuming a domestic partnership works like marriage, or that your state offers one at all.
Employer group coverage and why a partner may not qualify
Many employees have access to supplemental group life insurance through work that lets them add coverage on a spouse, often at a simple group rate with limited or no individual underwriting. Whether that benefit extends to an unmarried domestic partner depends entirely on how the specific employer’s plan is written. Some employers extend spousal benefits to a registered or documented domestic partner; many do not, limiting the spousal rider strictly to a legal spouse.
This is worth checking directly with your benefits department rather than assuming either answer. If your employer’s plan does extend to domestic partners, it is often worth using, since group rates and simplified underwriting are genuinely advantageous. If it does not, that gap is one more reason an individually owned policy, sized the way this piece describes, carries more of the real weight for an unmarried couple than it might for a married one who can lean on a spousal rider as a supplement.
Watch out: even where an employer extends the benefit, confirm what documentation it requires to add a domestic partner, since it is often stricter than what an individual life insurance application asks for, sometimes requiring a notarized affidavit of domestic partnership or proof of cohabitation for a specific minimum period.
Naming each other versus setting up a trust for a shared child
For coverage meant to support your partner directly, naming them outright as beneficiary is simple and appropriate, the same as naming any other competent adult. Where it gets more structured is coverage meant to support a shared child specifically. An insurer will not pay a death benefit directly to a minor, so a policy intended to fund a child’s upbringing, rather than simply to support the surviving partner generally, benefits from the same structuring a married parent would use: a trust set up for the child, or a custodial account under your state’s version of the Uniform Transfers to Minors Act, rather than naming the child outright.
The decision of whether to name your partner directly or to route a portion of the coverage through a trust for your shared child is really a question of what each dollar is for. Coverage meant to replace your own income so your partner can keep the household running points toward naming your partner directly. Coverage specifically meant to be preserved for your child’s education or long-term needs, regardless of what else happens, points toward a trust. Many couples split a single build across both, naming the partner directly for the income-replacement portion and a trust for a dedicated education or goal allowance. Our explainer on naming a trust as your beneficiary covers how that structure is actually set up.
A note on common-law marriage
A small number of states still recognize common-law marriage, under which a couple who meets specific state-defined criteria, commonly including cohabitation for a period, presenting themselves publicly as married, and intending to be married, can be treated as legally married without ever holding a ceremony or a license. Where it applies, a common-law marriage generally carries the same legal weight as a formal one, including the automatic spousal treatment that solves the insurable interest and default inheritance questions this piece otherwise walks through in detail.
The criteria are specific, vary meaningfully by the state that recognizes them, and are not something to assume applies to your situation based on how long you have lived together alone. Whether a given state still recognizes new common-law marriages at all, and exactly what a couple has to show to qualify, changes over time and differs from state to state, so this is squarely a question for an attorney licensed in your own state rather than something to self-diagnose from a general description. A couple who believes they may qualify should raise it directly with an estate planning attorney, since it can meaningfully change both the insurance application and the broader estate planning picture.
Joint policy or two individual policies: which fits an unmarried couple
A joint policy insures two people under one contract, most commonly as a first-to-die policy that pays a single death benefit on whichever partner dies first and then ends, leaving the survivor with no coverage at exactly the point they may need it most. Two individual policies, one on each partner, avoid that gap entirely: each partner’s coverage continues on its own regardless of what happens to the other’s.
For an unmarried couple specifically, individual policies carry an additional advantage worth naming. Each partner directly owns and controls their own policy, including the beneficiary designation, without a joint contract’s shared ownership structure adding another layer of questions if the relationship changes. Our explainer on joint life insurance covers the full mechanics of both product types, including the narrower cases, mainly high-value estate planning, where a joint survivorship policy genuinely fits. For most unmarried couples building ordinary income-replacement coverage, two individual policies sized separately is the more flexible starting point.
Sizing coverage when finances are not legally merged
Because an unmarried couple’s finances are not automatically merged the way a married couple’s often are, sizing coverage benefits from being explicit about what is actually shared versus what belongs to one partner alone. A shared mortgage is a shared obligation regardless of marital status; each partner’s own income is their own income, replaced on their own policy. The method below builds one partner’s coverage from five lines, the same approach used elsewhere on this site for sizing any individual’s policy.
- Income replacement, that partner’s own income, for the years it would be needed.
- Their share of shared debt, most commonly a joint mortgage, which either partner may remain fully liable for depending on how the loan is structured.
- Paid care or backup support, if the couple has a child together and the surviving partner would need help managing work and caregiving alone.
- A goal allowance, for education or whatever specific long-term goal the income was supporting.
- Final expenses and a household transition fund.
A worked example: one household, two incomes, no marriage license
Take an unmarried couple who have lived together for six years and share a 4 year old child. Partner A, 35, earns $75,000 a year. The couple holds a joint mortgage with a $280,000 balance, for which most mortgage agreements make each borrower individually responsible for the full amount, not merely half, if the other cannot pay. This build sizes Partner A’s own policy; Partner B would run the same method against their own income for a separate policy.
| Replacement-cost line | How it is sized | Illustrative amount |
|---|---|---|
| Income replacement | $75,000 x 14 years to the child’s 18th birthday | $1,050,000 |
| Shared mortgage | Full balance, since the mortgage is joint and several | $280,000 |
| Paid care or backup support | $16,000 x 14 years | $224,000 |
| Goal allowance | Flat illustrative allowance | $40,000 |
| Final expenses and transition fund | Flat illustrative allowance | $20,000 |
| Replacement-cost total | $1,614,000 |
That rounds to a $1,625,000 policy for Partner A alone. The mortgage line uses the full balance rather than a notional half, because most joint mortgages make each borrower liable for the whole debt, not a share of it, which is worth confirming on your own loan documents rather than assuming.
What one partner's coverage is actually made of
The five replacement-cost lines in the worked example, drawn to scale against the largest.
Income replacement is the largest line by a wide margin, the same pattern as any individual coverage build, with the shared mortgage as the second-largest piece specifically because it is a joint and several obligation.
The $1,614,000 total, split by line
Shares of the illustrative build before rounding to a $1,625,000 policy.
Income and the shared mortgage together are about 82% of the total, which is the practical shape of coverage for a partner carrying both an income and a joint debt obligation.
Choosing a term length
Round the years of dependency up to the next term length insurers actually sell, commonly 10, 15, 20, 25, or 30 years. For the worked household, the child is 4 and dependency runs 14 years, which rounds up to a 15-year term rather than a 10-year term that would expire two years before the child turns 18. Our walkthrough on choosing a term length covers the general decision, including laddering when the mortgage and the child’s dependency years do not end at the same time.
What this coverage actually costs
An illustrative figure for a healthy nonsmoker at 35, buying $1,625,000 of 15-year level term, is near $72 a month, or roughly $868 a year. Across the full 15-year term that comes to approximately $13,023 in total premiums. Those are illustrative midpoints for a healthy applicant, not quotes, and the real spread is wide: tobacco use, a health condition that triggers a rating, and the specific carrier can all move the figure meaningfully in either direction. Our note on comparing life insurance quotes covers what makes two quotes genuinely comparable.
Children, a shared mortgage, and other complicating factors
A child shared between unmarried partners is, legally, the same as a child born to married parents for most purposes relevant here: both legal parents have the same parental rights and obligations regardless of marital status in most states. Where unmarried couples genuinely diverge from married ones is in everything around the child’s financial security specifically tied to the parents’ marital status, which is why the beneficiary designation and a guardianship plan matter as much here as they do for any parent, married or not, and why our note on life insurance for single parents is worth reading alongside this one for the guardian and trust mechanics, even though it is written for a different household structure.
A shared mortgage deserves its own close look specifically because of how joint and several liability works: if one borrower dies, most mortgage agreements leave the surviving borrower responsible for the entire remaining balance, not half of it. Confirming this on your own loan documents, rather than assuming the debt splits evenly, is what makes the mortgage line in the sizing method above a realistic number rather than an optimistic one.
What happens if the relationship ends
A life insurance policy is entirely unaffected by a breakup; it continues exactly as written for as long as the owner keeps paying premiums. What does not update automatically is the beneficiary designation. If an ex-partner is still named when the insured dies, years after the relationship ended, the death benefit generally still goes to that ex-partner, because the insurer pays according to the form on file, not according to the current state of anyone’s relationships.
This is a genuinely common and avoidable failure. Reviewing and, where needed, updating beneficiary designations after any major relationship change, a breakup, a new relationship, a marriage, deserves to be a standard item on the same list as updating a will, not something that only gets noticed when it is already too late to fix.
The policy’s ownership also stays with whoever originally owns it, not with the relationship. If Partner A owns a policy on their own life with Partner B as beneficiary, a breakup does not transfer, cancel, or modify that policy in any way; Partner A keeps full control, including the right to change the beneficiary to someone else entirely, the moment they choose to. Nothing about ending the relationship is required to trigger that update, and nothing happens automatically either. The update is a deliberate, simple step that only happens if someone actually takes it.
Common mistakes unmarried couples make with this decision
- Assuming insurable interest works like marriage. It does not presume itself; it has to be documented, usually easily, through shared finances or housing.
- Never completing a beneficiary designation at all. Without one, a partner has no automatic claim, unlike a spouse under some states’ default rules.
- Leaving an old beneficiary in place after a breakup. The policy pays the name on the form, not the current relationship.
- Defaulting to a joint policy without comparing it to two individual ones. A joint first-to-die policy leaves the survivor uninsured at exactly the point coverage matters most.
- Treating a domestic partnership registration as equivalent to marriage. It is useful evidence and, in some states, grants specific protections, but it is narrower than marriage almost everywhere it exists.
- Skipping a will on the assumption that a beneficiary form covers everything. A beneficiary designation controls only the policy; everything else an unmarried partner might need to inherit still requires a will or other estate planning.
When to recheck the coverage
- A relationship change, including moving in together, a breakup, or a new relationship, each of which should trigger a beneficiary review.
- A new child, which adds a full new set of lines rather than simply extending the old ones.
- A significant income change for either partner.
- Paying off or taking on debt, especially a mortgage refinance that changes the balance or the names on the loan.
- A move to a different state, since domestic partnership and inheritance rules vary and do not travel uniformly.
- A domestic partnership registration or a later marriage, either of which can change what documentation and defaults apply.
A rerun every couple of years, plus one after any of those events, keeps the plan current. Treat a beneficiary review as its own line item on that schedule, separate from the coverage-amount review, since the two can drift out of date independently: a policy can remain perfectly well sized while naming entirely the wrong person, and a policy can be correctly routed to the right partner while being years out of date on the amount. Our policy checkup covers the general version of this habit.
Put your own numbers in
The worked example demonstrates the method, not a number to adopt. The companion beside this answer rebuilds the same five-line total as you change your own income, your child’s age if applicable, your share of shared debt, and what paid care would cost where you live, then rounds it to a face amount insurers actually issue and prices an illustrative premium against it.
The bottom line
Buying life insurance as an unmarried couple is mechanically straightforward once the one real difference from marriage is handled: showing insurable interest at application, which most long-term, financially interdependent couples can do easily through a joint mortgage, shared accounts, or a child in common. The part that genuinely cannot be skipped is everything that happens afterward without the automatic protections marriage provides: a correctly named, kept-current beneficiary designation, and a will covering what the policy does not. Size the coverage using the same method any individual would, with your own income, your share of shared debt, and your household’s real costs, and put your own figures through the coverage calculator. Then do the one thing a married couple can more easily skip: confirm, in writing, that the people this money is meant to reach are actually the people named to receive it.
CoverKin does not sell policies or earn a commission on the ones you buy, so treat this explainer as general education rather than legal, tax, or financial advice. Insurable interest standards, domestic partnership law, and default inheritance rules all vary by state and change over time, and nothing above should be read as describing your own state’s specific rules. Income, debts, and whether children are involved differ enormously between households, and every figure used here was chosen to show how the arithmetic works rather than to describe your own costs. The premium figures are illustrative midpoints for a healthy applicant, not quotes. Have an estate planning attorney in your own state review your beneficiary designations, any domestic partnership question, and your will, and confirm your coverage amount with a licensed, fee-only or independent insurance professional before you buy.
Frequently asked questions
Can unmarried partners buy life insurance on each other?
Yes, in most cases, as long as the applicant can show insurable interest, a financial or dependency relationship that means the applicant would actually suffer a loss if the insured partner died. Marriage automatically satisfies that requirement; an unmarried couple typically has to demonstrate it instead, through shared finances, shared debt, cohabitation, or dependents in common. Most long-term, financially interdependent unmarried couples can show this without difficulty. A newer relationship with no shared finances or obligations may face more questions, or may need to wait until that interdependence is more established and documentable.
What is insurable interest, and why does it matter for unmarried couples?
Insurable interest is the requirement that the person applying for a policy on someone else's life would genuinely suffer a financial loss from that person's death, and it exists to prevent life insurance from being purchased as a wager on a stranger's life. Spouses satisfy it automatically because marriage itself is treated as establishing shared financial interest. An unmarried couple does not get that automatic presumption, so the relationship, specifically its financial interdependence, has to be shown rather than assumed. This is a one-time hurdle at application, not an ongoing requirement checked again later, and once a policy is issued it generally stays in force regardless of how the relationship changes.
What documentation do insurers ask unmarried couples to prove insurable interest?
Common evidence includes a joint mortgage or lease showing both names, joint bank or credit accounts, a shared dependent such as a child in common, a domestic partnership or civil union registration where your state offers one, and simply a documented length of cohabitation. No single document is universally required, and insurers vary in exactly what they ask for and how much they want. The practical takeaway is to gather what you already have, joint financial accounts and housing documents are usually the easiest, rather than assuming you need something formal like a domestic partnership registration that your state or employer may not even offer. A licensed independent agent experienced with unmarried applicants can also tell you upfront which carriers tend to be more flexible about this specific question before you commit to a full application.
Does an unmarried partner automatically inherit anything without a beneficiary designation?
No, and this is one of the sharpest practical differences from marriage. Most states' default inheritance rules, which apply when someone dies without a will, generally recognize spouses and blood relatives, not an unmarried partner, no matter how long the relationship lasted or how intertwined the finances were. The same logic applies to a life insurance death benefit: it goes to whoever is named as beneficiary on the policy, not automatically to a partner, regardless of relationship length. This makes the beneficiary designation, and a will covering everything else, functionally more important for an unmarried couple than for a married one, where some automatic protections exist as a backstop.
Should unmarried partners buy a joint policy or two individual policies?
Two individual policies are generally the more flexible choice for the same reasons they are usually recommended for married couples: each partner can size, underwrite, and later convert or cancel their own policy independently, and a first-to-die joint policy pays out once and leaves the survivor with no coverage at exactly the moment they may need it most. For an unmarried couple specifically, individual policies also sidestep a layer of complexity: each partner directly owns and controls their own contract, including the beneficiary designation, without a joint policy's shared ownership structure raising its own questions if the relationship later changes. Our explainer on joint life insurance covers the mechanics of both product types in full.
Does a domestic partnership or civil union change anything?
It can help with the insurable interest question, since a registered domestic partnership or civil union is documentary evidence of a recognized relationship, but it does not generally grant the same automatic inheritance and spousal defaults that marriage does in most states. Treat registration as one useful piece of evidence for insurable interest and, where it exists, certain other protections your state specifically grants registered partners, not as a substitute for a will and a correctly completed beneficiary designation. The rules vary significantly by state, since not every state offers registration at all, so confirm your own state's specific treatment rather than assuming it works like marriage.
What happens to the coverage if the relationship ends?
The policy itself is unaffected by a breakup; coverage continues exactly as written until the owner changes or cancels it. What does not change automatically is the beneficiary designation. If an ex-partner is still named as beneficiary when the insured dies, the death benefit generally still goes to that ex-partner, because insurers pay according to the designation on file, not according to the current state of the relationship. Updating the beneficiary designation is a simple form, but it is a step that has to be taken deliberately. Reviewing beneficiaries after any major relationship change is worth treating as a standard item, not an afterthought.
How much life insurance should an unmarried couple buy?
Size each partner's policy around what their own death would actually cost the household: their income replacement for the years it is needed, their share of shared debt such as a mortgage, any paid care a surviving partner would need if children are involved, and a transition fund. An illustrative build for one partner earning $75,000, with a $280,000 shared mortgage and a 4 year old child in common, lands near $1,625,000. That is a demonstration of the method, not a number to copy, because income, debts, and whether children are involved move the total by a wide margin.
