Estate Planning for Unmarried Couples: Filling the Legal Gaps

Unmarried couples — whether long-term partners who never married, cohabiting couples in states without common-law marriage, or queer couples in jurisdictions that complicate recognition — face a planning gap that married couples rarely have to think about. Without a marriage certificate, the default legal rights spouses receive automatically simply don't exist. Hospital visitation, medical decisions, inheritance, tax benefits, and probate priority all default to next-of-kin — which usually means parents or siblings, not the partner.

Closing the gap takes paperwork, but the paperwork is straightforward. Here is the full set.

What's missing without marriage

Married couples get all of the following automatically:

• Right to make medical decisions for an incapacitated spouse
• Right to hospital visitation
• Right to inherit a share of the estate even without a will (elective share / intestate share)
• Right to administer the deceased spouse's estate as personal representative
• Right to social security survivor benefits
• Right to step into pension and retirement plan benefits
• Right to file joint tax returns
• Right to spousal exemption from federal and state estate tax
• Right to make funeral and burial decisions

Unmarried partners get exactly none of these by default. Every one requires affirmative legal planning — or, in some cases, simply cannot be replicated without marriage (joint tax filing, social security survivor benefits).

Document 1: Wills, on both sides

Each partner needs a will explicitly naming the other as beneficiary. Without a will, the partner inherits nothing — state intestacy laws send the estate to parents, then siblings, then more distant relatives, in that order. Cohabitation, joint accounts, decades of shared life — none of it matters to the intestacy statute.

Both partners' wills should also name each other as primary executor, with a backup who is acceptable to both sides of the family. See our how to write a will guide for the basics.

Document 2: Durable financial power of attorney

If one partner becomes incapacitated, the other has no automatic right to manage their finances — pay their bills, access their accounts, sell property, file taxes. A durable financial POA designates the partner as agent during incapacity, surviving the principal's incapacity (hence "durable") until death.

Without it, the family has to petition for a conservatorship — a court process that's expensive, slow, and often results in a court-appointed conservator (frequently a relative) rather than the partner.

Document 3: Healthcare power of attorney (or healthcare proxy)

The healthcare POA designates the partner as the medical decision-maker if the principal cannot make decisions for themselves. Without it, hospitals follow state default hierarchies — typically spouse, then adult children, then parents, then siblings. The partner is not on the list.

Pair the healthcare POA with HIPAA authorization explicitly naming the partner so providers can share medical information. Many hospitals will accept the HIPAA form even without the POA for purposes of visitation and information.

Document 4: Advance directive (living will)

Separate from the healthcare POA, the living will specifies end-of-life treatment preferences — ventilation, feeding tubes, resuscitation, comfort care. Combining the healthcare POA and living will into a single advance directive document is common; either way, both functions need to be addressed. Our advance healthcare directive guide covers the specifics.

Document 5: Beneficiary designations

Retirement accounts, life insurance, annuities, transfer-on-death brokerage accounts, payable-on-death bank accounts. All of these pass by beneficiary form, outside the will. For unmarried partners, this is often the highest-leverage planning tool — these designations override intestacy entirely, so even without a will the partner inherits these assets directly.

Note that 401(k)s and other ERISA-governed retirement plans default to the spouse and require spousal consent to name anyone else. For unmarried partners, no consent is needed — the form just gets filed.

Document 6: Hospital visitation authorization

A small but emotionally critical document. Many hospitals have their own visitation forms; some accept a written designation. The Centers for Medicare and Medicaid Services require participating hospitals to allow visitation by the patient's designated representative regardless of relationship — but enforcement depends on having documentation ready at the front desk in a crisis.

Document 7: Funeral and disposition authorization

State law typically gives the next-of-kin the right to decide on burial vs. cremation, religious observances, and disposition of remains. Unmarried partners are not on the priority list. In some states, a written authorization (sometimes called a designated agent for disposition of remains) overrides the family default. Without one, the family of origin may make funeral decisions over the partner's objection — including refusing to acknowledge the relationship at the service.

Real property: titling matters

How real estate is titled determines what happens at death:

• **Sole ownership:** Passes by will. If no will, passes by intestacy (not to the partner).
• **Tenants in common:** Each owner's share passes by their will. The surviving partner does not automatically inherit the deceased's share.
• **Joint tenancy with right of survivorship:** Surviving owner automatically inherits the deceased's share — outside probate, outside the will. This is the standard structure for unmarried couples who want the survivor to keep the home.
• **Tenancy by the entirety:** Available only to married couples in most states.

Joint tenancy with right of survivorship is usually the right answer, but check state-specific rules — some states require explicit language ("as joint tenants with right of survivorship, not as tenants in common") to avoid the default of tenants in common.

Joint accounts

Joint bank accounts with right of survivorship pass to the surviving partner outside probate. They also expose the joint account to each owner's creditors and create issues if the relationship ends. For partners who want survivorship without intermingling, separate accounts with POD beneficiary designations achieve the same inheritance result without the joint exposure.

State recognition: common-law marriage and domestic partnership

A small number of states still recognize common-law marriage formed within their borders (Colorado, Iowa, Kansas, Montana, New Hampshire for inheritance only, Oklahoma, Pennsylvania pre-2005, Rhode Island, South Carolina pre-2019, Texas, Utah, DC). These statuses can grant inheritance rights similar to formal marriage — but proving common-law marriage requires evidence (cohabitation, holding out as married, intent), and many estates spend years in litigation establishing or refusing the status.

Some states and localities offer registered domestic partnerships or civil unions with varying inheritance and decision-making rights. The bar association in your state can confirm what status, if any, applies.

For couples who want full legal recognition without the common-law uncertainty, the cleanest answer remains: get married, even if just at the courthouse. For couples who don't want that, the documents above replicate most of the rights.

The conversation with family of origin

Even with perfect documents, family members can challenge the partner's role — particularly in cases where the relationship wasn't openly acknowledged with the family. Documentation reduces the chance of successful challenge but doesn't eliminate it.

The strongest preventive step is communicating the plan during life. Telling your parents and siblings that your partner is named in your will and powers of attorney puts them on notice and creates a record. Surprise disinheritance is the fuel for will contests; documented intent during life starves the fire.

What VoiceWill™ does

VoiceWill™'s voice intake explicitly handles unmarried-partner structures — naming the partner across the will, financial POA, healthcare POA, and disposition authorization in a single guided session. We produce a coordinated package rather than a stack of disconnected documents, and our family vault stores them in a single accessible location with both partners credentialed.

The bottom line

Marriage triggers about a dozen default legal rights automatically. Unmarried couples can replicate most of them with five or six documents: wills on both sides, durable powers of attorney, healthcare directives, beneficiary designations, joint titling on real estate, and disposition authorizations. The work takes an afternoon. The cost of skipping it is the partner standing outside the ICU while the family of origin makes the decisions.
