Estate Planning for Unmarried Couples

If you and your partner are not married, the law treats you as legal strangers when it comes to inheritance. Under every state's intestate succession rules — the rules that govern who inherits when someone dies without a valid will — an unmarried partner inherits nothing, regardless of how long you have been together or how intertwined your finances are. Your partner's assets would pass to their closest relatives: parents, siblings, or more distant family. The solution is deliberate, written planning. This guide explains the tools available and the gaps most unmarried couples overlook.

Why Unmarried Partners Are Invisible to Intestacy Law

Intestacy is the default rulebook every state has written for people who die without a valid will. Every state's version prioritizes blood relatives and legally recognized spouses. The list typically runs: spouse, children, parents, siblings, and so on outward through the family tree. Unmarried partners — no matter how long the relationship has lasted — do not appear on that list anywhere in the country. If your partner dies without a valid will, their estate passes to their next of kin, not to you. The same is true in reverse.

This is not a gap in the law waiting to be corrected. It is the law functioning exactly as designed. The only way to change the outcome is to plan ahead, in writing, before a death occurs.

The Foundation: A Valid Will

A will is the most direct way to name your partner as a beneficiary of your estate. It lets you decide who receives what, name an executor (the person who will administer your estate) of your own choosing rather than having a court appoint one, and express your intentions clearly on the record.

For a will to be valid, it must meet your state's formalities: generally in writing, signed by you, and witnessed by the required number of witnesses. Some states also recognize handwritten (holographic) wills; others do not. Requirements vary by state, so a document that is valid in one state may not work in another. If you move, have your will reviewed by a licensed estate attorney in your new state before assuming it still controls.

One critical limitation: a will controls only probate assets — property that does not already carry a named beneficiary or joint owner. Many of the most valuable assets people own pass entirely outside of the will, which is why the next steps matter just as much.

Non-Probate Transfers: Often More Important Than the Will

Certain assets pass directly to a named person at death, regardless of what any will says. These are non-probate assets, and they are governed entirely by the beneficiary designation on the account paperwork:

• Life insurance and retirement accounts (401(k), IRA, pension) pass to whoever is named on the account form. If a family member is listed and you never updated it, your partner receives nothing — even if your will says otherwise.
• Payable-on-death (POD) bank accounts and transfer-on-death (TOD) brokerage accounts let you name a beneficiary who receives the asset at your death without any probate process.
• Property held in joint tenancy with right of survivorship passes automatically to the surviving co-owner. Some couples hold a shared home this way, but the legal and tax implications vary by state and should be reviewed by an attorney before you change how a deed is titled.

For an unmarried couple, keeping beneficiary designations current on every account is just as important — and often more immediately consequential — than having a will. A beneficiary designation overrides a will. An outdated designation on a retirement account sends those funds to whoever is named on the form, period.

Revocable Living Trusts

A revocable living trust is an arrangement in which you transfer assets into a trust during your lifetime. You typically remain the trustee while you are alive and mentally competent, and you name a successor trustee who takes over if you become incapacitated or die. At your death, the assets in the trust pass to whoever you named as beneficiary — without probate.

For unmarried couples, a living trust offers two advantages over a will alone. First, it avoids probate, which can be slow, public, and expensive. Second, it can manage your assets if you become incapacitated before you die — a will takes effect only at death, while a trust can activate sooner and give your partner authority to manage shared finances without a court process. A revocable trust provides no special creditor protection or tax advantages by itself, and it must be properly funded — assets must actually be transferred into the trust — to do any good. Trusts are governed by state law, so the specifics vary.

Powers of Attorney and Health Care Directives

Estate planning is not only about death. Two documents address what happens if you are alive but unable to make decisions:

• A durable financial power of attorney (POA) authorizes your partner to manage your financial affairs while you are alive. Without one, they have no legal authority to pay your bills, access your bank accounts, or make financial decisions on your behalf if you are incapacitated. A POA ends at death; after that, authority shifts to your executor.
• A health care power of attorney or advance directive designates who can make medical decisions for you if you cannot make them yourself. Without this document, hospitals and providers will default to next of kin — which, for an unmarried couple, typically means your partner has no say at all, regardless of the circumstances.

Both documents must follow your state's execution formalities. Have them drafted or reviewed by a licensed attorney in your state.

Gaps Unmarried Couples Most Often Miss

• Outdated beneficiary designations. Retirement accounts and life insurance from before the relationship may still name a former partner, a parent, or a sibling. Review every account, not just the newest ones.
• Real estate titled in one name. A home you share may be in only one partner's name. If that partner dies without a will, the surviving partner may have no legal claim to the property — even if they have lived there for years.
• Family override risk. Without a will, a deceased partner's family can legally inherit everything and may have priority over any informal understanding you had about shared property or possessions.
• No hospital or end-of-life rights. Without a health care directive, a partner's family may have decision-making priority in a medical crisis and may also control funeral and burial arrangements.
• Common-law marriage misconceptions. Common-law marriage is recognized in only a small number of states and requires meeting specific legal requirements. Do not assume it applies to your situation without verifying your state's current law.

What You Can Do

• Each partner should draft a valid will naming the other as a primary beneficiary and naming a chosen executor.
• Review and update beneficiary designations on all retirement accounts, life insurance, bank accounts, and brokerage accounts — including older accounts from previous employers.
• Consider adding POD or TOD designations to financial accounts where they are not already in place.
• Execute a durable financial power of attorney and a health care power of attorney or advance directive for each partner.
• If you own real estate together, confirm how the title is held and consult an attorney about whether the current arrangement reflects your intentions.
• If the estate is larger or more complex, consider a revocable living trust to avoid probate and provide for incapacity planning.
• Revisit all documents after any major life change: a move to a new state, the birth of a child, significant shifts in assets, or the end of the relationship.

This is general legal information, not legal advice. Estate and probate law is highly state-specific and the details change. Check the laws of your specific state or consult a licensed estate attorney in your state for guidance on your situation.
