What spouses get automatically that unmarried partners must build

Marriage works like a bundle of default settings. Without anyone filling out a form, a spouse is usually next in line to inherit, is first in line to make medical decisions, can claim Social Security survivor benefits and can receive property from the other spouse without federal estate tax. Unmarried partners get none of these by default. They are available only to the extent that you write them down, one document at a time. This post is a checklist of the gaps, grouped by area, with the reason each one matters and the step that closes it.

Life insurance closes some of these gaps well and others not at all. The checklist separates the two so you do not expect a policy to do a job that needs a different document. The couple in the examples, Dana and Eli, is hypothetical, and their numbers are illustrations only. State law drives many of the details, so use the lists as a set of questions for an attorney and your state insurance department rather than as legal advice. The companion guide, life insurance for unmarried partners, explains the insurance side in more depth.

How to use this checklist

Go through each group and mark every item as done, not applicable or open. Then deal with the open items in the order below. The sequence is deliberate: first the documents that matter if one of you is hurt or dies suddenly, then the ones that matter at a death, then the long-term planning.

Meet Dana, 41, who earns $70,000, and Eli, 39, who earns $50,000. They have lived together for eight years, own a house with a $240,000 mortgage titled to both of them, and share a car loan. They have no children together. Neither has a will. Dana has a term policy from years ago that names her mother as beneficiary. The sections below show how each gap applies to them.

Group 1: If one of you is hurt or ill

These come first because they matter while you are both alive.

• A health care proxy or medical power of attorney. Hospitals and doctors look first to a spouse for decisions when a patient cannot speak. A partner has no such default standing in many places, and the decision may fall to a parent or an adult child. A signed proxy names the person you choose.
• A privacy release for medical information. Privacy law limits what providers may tell people who are not authorized. A signed release lets your partner receive information and talk to doctors.
• A durable financial power of attorney. If you are incapacitated, a partner cannot pay your bills, access your accounts or manage your property without legal authority. A power of attorney names someone who can.
• Written wishes about visitation, funeral and burial. A partner has no default say over burial or cremation, and a surviving relative may have the legal right to decide. State law sets the order, and many states let you name an agent in writing to control disposition of remains.
• Who gets called. A card in your wallet and an entry in your phone naming your partner as an emergency contact helps in practice, even though it does not create legal rights.

What insurance does here: nothing. These are legal documents, not insurance, and a lawyer or a state-approved form can complete them. A disability policy covers a different risk, and the guide on life insurance vs disability insurance: which to buy first explains the difference.

For Dana and Eli: neither has a proxy, a release or a power of attorney. These are the first open items.

Group 2: Inheritance and probate

• A will. A spouse is typically protected by the state's rules when someone dies without a will. State intestacy laws then pass the property to a spouse, children or other relatives, and an unmarried partner is usually not on that list. Dana's property would go first to her relatives, such as her mother, rather than to Eli. A will lets you leave property to a partner. The guide on life insurance and your will explains how a will and a policy work together.
• Titling of shared property. How a house or a bank account is titled decides who gets it at death. Some forms of joint ownership pass the property automatically to the survivor, outside the will, while others do not. The options and names differ by state, and for real estate a lawyer or title company should confirm the form.
• Account beneficiaries. Bank accounts, brokerage accounts and retirement accounts often allow a beneficiary or transfer-on-death designation. Check each one.
• Understanding probate. Assets that pass by a beneficiary designation or joint ownership with survivorship generally avoid probate, the court process of settling an estate. Assets that pass only by will go through it. See does life insurance go through probate?.
• A named executor. An executor handles the estate. Without a will, a court appoints someone, and a partner has no priority.

What insurance does here: a policy pays the named beneficiary directly, outside probate. That makes it an effective way to give a partner cash even when the rest of the estate is stuck. It does not transfer a house or a bank account. For those, titling and a will do the work.

For Dana and Eli: the house is titled to both, so they should confirm how, since the form decides whether Eli keeps the house or shares it with Dana's heirs. Their wills are open items.

Group 3: Life insurance forms

This is where insurance is the main tool.

• A policy on each partner, sized to what the survivor would lose. Typically the survivor needs to cover housing costs, shared debts and the loss of one income. The How much life insurance do I need? and the guide on How much life insurance do I need? show how.
• The partner named as primary beneficiary. An unmarried partner has no claim on a policy unless named. Use the full legal name and the relationship.
• A contingent beneficiary. If the partner dies first or cannot be found, a contingent beneficiary receives the money. Without one, the benefit may go to the estate.
• Ownership that matches your intent. The usual arrangement is for each partner to be the owner and insured of their own policy. Cross-ownership, with each partner owning a policy on the other, requires an insurable interest and the insured's written consent in most states, and it complicates matters if the couple separates. See insurable interest: who can buy life insurance on whom.
• A review of old forms. Policies bought years ago often name a parent or a former partner. Beneficiary forms are honored as written, so a stale form sends the money to the wrong person. The guide on how to change your life insurance beneficiary explains how to update one.
• A plan for children. If one partner has children from an earlier relationship, decide whether a policy should name the children, the partner or a trust. A trust can combine the two aims by giving the partner the use of the money while preserving a share for the children.

An arithmetic check for Dana and Eli. Say the mortgage payment is $1,800 a month. That is $1,800 x 12 = $21,600 a year, or 43 percent of Eli's $50,000 income. If Dana died, Eli would have to pay that amount from his own pay, or sell. A simple starting point for Dana's coverage is the $240,000 mortgage plus a year of her income, $70,000, to give Eli time to adjust: $240,000 + $70,000 = $310,000. A round $300,000 or $350,000 20-year term policy would fit that need. For Eli, the same logic gives $240,000 + $50,000 = $290,000, rounded to about $300,000. These are illustrative amounts. Real sizing depends on the shared debts, the household budget, what each would do if the other died and whether the mortgage is protected by other coverage.

Group 4: Government and employer survivor benefits

These are real gaps that insurance can only partly fill.

• Social Security survivor benefits. Survivor benefits are paid to a widow or widower, not to a partner who was never married to the worker. Children can qualify in some cases, and the guide on Social Security survivor benefits and the $255 death payment explains who is eligible. The lump-sum death payment of $255 also depends on the relationship to the worker. Ask the Social Security Administration for current rules before you plan around any of this.
• Pension survivor rights. Federal rules require spousal consent before a married worker gives up survivor benefits from many employer pensions. An unmarried partner has no such right, and the pension may end at the worker's death or go to someone the worker names, if the plan allows.
• Retirement accounts. A spouse who inherits an account generally has more flexibility than another beneficiary, including treating it as their own. A partner who is not a spouse generally faces shorter payout windows. Name the partner on the account, and ask a tax professional how the rules apply.
• Employer group life. Plans differ on who counts as a dependent. Some include domestic partners; others cover only legal spouses. Ask human resources. The employer-paid cost for a non-spouse partner may create taxable income, so check before enrolling.
• Health insurance. Coverage under a partner's plan depends on plan rules and may end when the policyholder dies. A partner should know what the options would be.

What insurance does here: an individual policy can replace some of the lost income, which makes it a partial substitute for survivor benefits. It does not replace the lifetime nature of a pension or Social Security. The sizing should reflect this: if a spouse would normally have had survivor income for decades, a partner needs a larger sum or a longer term to fund something similar.

Group 5: Taxes and gifts

• No unlimited marital deduction. Spouses can generally leave unlimited property to each other without federal estate tax, provided the survivor is a U.S. citizen. Unmarried partners cannot. What passes to a partner counts against the giver's estate tax exclusion, which is $15,000,000 per person in 2026. Few households come near that, so for most couples this is a planning footnote. If your combined assets are large, speak to an estate attorney.
• Gifts between partners. Gifts above the annual exclusion, $19,000 per recipient in 2026, require a gift tax return, though tax is owed only after the lifetime exclusion is used. Paying a partner's premium or buying a policy owned by one partner on the other can raise gift questions. The glossary entries for the federal estate tax exemption and gift tax annual exclusion explain the concepts.
• The three-party trap. A policy where the owner, the insured and the beneficiary are three different people can produce a gift when the benefit is paid. See The Goodman triangle: an expensive ownership mistake.
• Income tax on death benefits. A death benefit paid to a named beneficiary is generally not income to the beneficiary, whether or not the beneficiary is a spouse.

Group 6: Housing and shared debts

• A mortgage or lease in both names. If both of you signed, both are responsible for the debt. If only one signed, the other may have no rights to the home at all.
• Co-signed loans. A car loan or a private student loan can pass to a co-signer at the borrower's death. List them and include them in your coverage calculation.
• A cohabitation agreement. Many couples write an agreement setting out who owns what, how expenses are shared and what happens if the relationship ends. It is a contract and a lawyer should draft it.

Group 7: Keeping everything consistent

Plans fail more often because documents disagree than because any one is missing. A will that leaves everything to a partner does not change who is named on a life insurance form, because the beneficiary designation controls the policy. The post where a will stops and a beneficiary form takes over explains why the form beats the will, and the post marriage and beneficiary myths: why a spouse is not automatically paid tests common beliefs about what a spouse receives.

Check these items once a year:

1. Names on every beneficiary form match your current wishes.
2. The will, the powers of attorney and the proxy are signed and current.
3. Titles to the house and bank accounts match what you intended.
4. Employer plans and retirement accounts are updated after any job change.
5. Your partner knows where the documents are and who to call.

If you decide to marry

Marriage changes the picture in a single step: most of the defaults above begin to apply. It does not update your beneficiary forms, and it does not replace your documents. Review them afterward. The post on same-sex couples and policies on each other: questions answered in depth works through ownership and beneficiary questions for couples, and its answers apply to any couple in a similar position. Some couples choose not to marry for personal, financial or legal reasons, such as the effect of marriage on a benefit. That is their right, and this checklist exists so that choice does not leave the family unprotected.

When to get help

A lawyer who handles wills and estates can draft the will, powers of attorney, proxy and cohabitation agreement, and confirm how your state treats joint ownership. A fee-only financial planner can size insurance and review retirement accounts. A tax professional can answer questions about gifts and inherited accounts. The state insurance department can answer questions about forms and complaints about insurer handling.

Key takeaways

• Marriage supplies default rights to inherit, make medical decisions, claim survivor benefits and receive property tax-free. Unmarried partners get these only through documents.
• A life insurance policy with the partner named as beneficiary pays directly and outside probate, but it does not replace a will, a proxy, a power of attorney or the title to shared property.
• Size each partner's coverage to what the survivor would lose: shared debts, housing costs and the lost income, plus some adjustment time.
• Survivor benefits from Social Security and many pensions are generally not available to unmarried partners, so insurance should partly fill that gap.
• Beneficiary forms control the policy whatever the will says. Review every form each year and after any change in the relationship.
