Unmarried Partner Estate Planning: 6 Documents You Must Have (2026)

What Happens Without a Plan — State by State

| ContentWhat Happens to Your Partner?ContentWho Gets Your Estate Instead?** | | --- | --- | --- | | You die without a will — no children | Your partner receives NOTHING under intestate succession in any state without common law marriage | Your parents (if living); then your siblings; then your nieces/nephews; then more distant relatives | | You die without a will — you have children | Your partner receives NOTHING; your children receive everything | Your biological/adopted children inherit your entire estate; if children are minors, a court-appointed guardian manages the money | | You become incapacitated — no power of attorney | Your partner cannot make financial decisions, access joint accounts (if not jointly titled), pay bills, or manage your affairs | A court-appointed conservator — possibly your blood relatives — gains control; can take months and cost thousands in legal fees | | Medical emergency — no healthcare directive | Your partner may be excluded from medical decisions and information; blood relatives (even estranged ones) have priority | Your parents, adult children, or siblings have legal priority for healthcare decisions in most states | | You die — shared home not in joint names | Your partner has no legal right to stay in the home; blood relatives who inherit may demand they leave; probate process delays any transfer | Whoever inherits the property under your will (or intestacy) owns the home; partner has no possessory right | | Inheritance tax state (PA, NJ, NE, KY) | Even with a will leaving everything to your partner, inheritance tax is owed at the highest rate: PA 15%, NJ up to 16%, KY up to 16%, NE up to 18% | Your partner inherits but pays maximum inheritance tax on the full amount — no spousal exemption available to unmarried partners |

Document 1 — The Will

A will is the most basic protection. It allows you to name your partner as your primary beneficiary and executor. Without a will, intestate succession laws — which do not recognize your partner at all — control who receives your estate.

| ContentWhy It Matters for Unmarried PartnersContentWhat to Include** | | --- | --- | --- | | Primary beneficiary | Without this, your partner receives nothing | Leave the bulk of your estate to your partner by name | | Executor / Personal Representative | Your partner needs authority to manage your estate | Name your partner as executor; name backup in case they predecease you | | Guardian for minor children | If you have minor children, your partner is NOT automatically their guardian — a blood relative could petition the court | Name your partner as guardian (if they are the co-parent or you want them as guardian); courts give great weight to named guardian but can override | | No-contest clause | Discourages blood relatives from challenging the will | Standard in wills that may face family opposition |

A Will Alone Is Not Enough — Blood Relatives Can Challenge It:

Disgruntled family members who expected to inherit can contest a will on grounds of undue influence, lack of capacity, or improper execution. A surviving partner is particularly vulnerable to these challenges — especially if the couple was not married and family members were unaware of or opposed to the relationship. A revocable living trust is harder to challenge than a will, passes assets more privately (no probate), and provides additional protections. For unmarried partners, a trust is strongly recommended in addition to a will.

Document 2 — Revocable Living Trust

A revocable living trust provides stronger, more private, and harder-to-challenge protection than a will alone. Assets in the trust pass to your partner at death without probate — no court involvement, no public record, no opportunity for hostile family members to intervene. The trust also provides incapacity protection: if you become disabled, your successor trustee (ideally your partner) manages trust assets without a court-supervised conservatorship.

| ContentDetail** | | --- | --- | | No probate | Trust assets pass directly to partner without court; blood relatives cannot easily challenge or delay | | Private | Trust is not a public record; will going through probate is public — anyone can see what you left to your partner | | Harder to contest | Revocable living trusts are more difficult to challenge than wills; your consistent pattern of managing the trust during your lifetime demonstrates capacity and intent | | Incapacity management | If you become incapacitated, your partner (as successor trustee) manages trust assets immediately, without court involvement | | Out-of-state property | If you own property in multiple states, a trust avoids multiple probate proceedings — all trust property is managed by the trustee regardless of state |

Document 3 — Durable Power of Attorney (DPOA)

A Durable Power of Attorney authorizes your partner to manage your financial affairs — pay bills, manage bank accounts, file tax returns, manage investments — if you become incapacitated. Without a DPOA, your partner has no legal authority over any individually-owned accounts or property, even if you have lived together for decades. A court-supervised conservatorship is the only alternative — a process that takes months and costs thousands, and may result in a blood relative being appointed instead.

Document 4 — Healthcare Directive and Medical Power of Attorney

A Healthcare Directive (also called a Living Will or Advance Directive) specifies your medical wishes — life support, resuscitation, organ donation, comfort care. A Medical Power of Attorney (Healthcare Proxy) designates your partner as the person who makes healthcare decisions if you cannot make them yourself. Without these documents, hospitals default to the legal hierarchy: spouse, adult children, parents, adult siblings — your unmarried partner does not appear on this list and may be completely excluded.

Without a Healthcare Directive, the Hospital May Turn Your Partner Away:

This scenario is not hypothetical. Medical staff follow the legal hierarchy for next-of-kin decision-making. An unmarried partner — no matter how long the relationship — has no standing unless specifically designated in a healthcare directive. In a medical emergency, your estranged parent or your sibling whom you have not spoken to in years may have more legal authority over your care than your partner of 15 years. Execute a Healthcare Directive and Medical Power of Attorney today. These documents are inexpensive ($0–$300 to have a lawyer prepare) and can be drafted online in many states. They are the most urgent documents for any unmarried couple.

Document 5 — Beneficiary Designations on All Financial Accounts

Every IRA, 401(k), 403(b), bank account (POD), brokerage account (TOD), and life insurance policy should name your partner as beneficiary. These designations pass assets directly at death, completely bypassing your will and trust. They are often the fastest and least expensive way to transfer the bulk of your estate to your partner — and they are not subject to probate challenges by blood relatives.

| ContentName Your Partner AsContentNote** | | --- | --- | --- | | IRA / Roth IRA | Primary beneficiary; also name contingent (backup) beneficiary | For large IRAs, consider whether naming a trust as beneficiary is more tax-efficient under SECURE Act 2.0 rules — consult estate attorney | | 401(k) / 403(b) | Primary beneficiary | Note: if you are currently unmarried, no spousal consent is required for 401(k) beneficiary designation; if you remarry, new spouse may have automatic rights | | Life insurance | Primary beneficiary | Consider whether proceeds should go directly to partner or be held in trust (e.g., if partner may need creditor protection or disability assistance management) | | Bank accounts (POD) | Named beneficiary on each account | Most banks allow online update; bring partner's full name, DOB, and Social Security number | | Brokerage accounts (TOD) | Named beneficiary | If account is jointly titled with partner as JTWROS, TOD is less critical — but name contingent beneficiary |

Document 6 — Property Titling: Joint Tenancy and Cohabitation Agreement

How you title jointly-used property is as important as your will. For the shared home and major assets, joint tenancy with right of survivorship (JTWROS) passes the asset automatically to the surviving co-owner at death — with no probate, no will challenge, and no delay. A Cohabitation Agreement is a written contract between unmarried partners that defines each person's property rights, financial responsibilities, and what happens if the relationship ends or one partner dies.

| ContentWhat It DoesContentLimitation** | | --- | --- | --- | | Joint Tenancy with Right of Survivorship (JTWROS) on home | Surviving partner automatically becomes sole owner of the home at death; no probate; no will challenge possible | Creating JTWROS may trigger gift tax if one partner contributes more than the other (over $19,000 annual exclusion); capital gains considerations for appreciated property — consult CPA | | Joint bank/brokerage accounts | Surviving partner has immediate access to joint accounts; no probate delay for joint assets | Creditors of either joint owner can reach the full account in some states; consider whether to keep some separate accounts for personal creditor protection | | Cohabitation Agreement | Defines property ownership, financial contributions, what happens at death or breakup; enforceable contract under contract law — not estate law | Must be in writing; both parties should have independent legal counsel; courts in some states scrutinize cohabitation agreements; not a substitute for a will/trust but a useful complement |

Inheritance Tax — The Hidden Cost for Unmarried Partners in 6 States

If You Are in PA, NJ, or NE — Consider Marriage or Structured Life Insurance:

For unmarried partners in Pennsylvania (15%), New Jersey (up to 16%), or Nebraska (up to 18%), the inheritance tax on a large inheritance can be devastating. A $1M estate left to an unmarried PA partner produces a $150,000 inheritance tax bill. Three planning options: (1) Marriage eliminates the inheritance tax entirely — surviving spouses are exempt in all 6 inheritance tax states; (2) Life insurance paid to the partner as named beneficiary is generally NOT subject to inheritance tax (life insurance proceeds to a named beneficiary are not part of the probate estate in most states — ⚠ verify your state); (3) Lifetime gifting — gifts made during lifetime reduce the estate below the threshold; PA gifts made more than 1 year before death are generally exempt from PA inheritance tax.
