Estate Planning for Unmarried Couples

If you and your partner are not married, the law treats you as strangers. That is not an exaggeration. It does not matter if you have lived together for 30 years, raised children together, or built a life side by side. Without the right legal documents in place, your partner has no automatic right to inherit your property, make medical decisions on your behalf, or even visit you in the hospital.

Married couples receive dozens of legal protections automatically. Unmarried couples receive none. This gap means that unmarried partners need to be more deliberate about estate planning than married couples, not less. The good news is that you can close most of these gaps with the right documents and strategies.

This guide walks you through the legal reality unmarried couples face, the documents you need, and the steps you can take today to protect each other. If you are not sure where to start, our estate planning assessment can help you figure out which documents you need most.

The Legal Reality for Unmarried Couples

Let's start with what the law actually says, because the consequences of doing nothing are serious.

You Are Legal Strangers

Every state's intestacy laws determine who inherits when someone dies without a will. These laws follow a strict hierarchy: spouse, children, parents, siblings, and then extended family. An unmarried partner does not appear anywhere on this list. Not in Florida, not in California, not in any state.

This means that without a will, everything your partner owns goes to blood relatives. The home you shared, the bank accounts you built together, the belongings you accumulated over decades: all of it goes to family members, even if those family members were estranged or hostile to the relationship.

What Unmarried Partners Do Not Get

Here is a direct comparison of the rights married couples receive automatically versus what unmarried couples get.

This table is not meant to discourage you. It is meant to show you exactly why planning matters and where to focus your energy.

The Seven Documents You Need

Married couples can get away with minimal planning because the law fills in the gaps. Unmarried couples cannot afford that luxury. Here are the seven documents every unmarried couple should have in place.

1. Last Will and Testament

A will is the only way to ensure your partner inherits your property. Without one, intestacy laws send everything to blood relatives.

Your will should specifically name your partner as a beneficiary and clearly state your wishes. Be specific about what you want your partner to receive. The more detail you include, the harder it is for family members to challenge your wishes.

One thing to keep in mind: wills go through probate, which is a public court process. Family members who disagree with your choices can contest the will. While will contests are not easy to win, they can be expensive and stressful for your partner during an already difficult time.

To learn more about how wills fit into your overall estate plan, see our guide on estate planning basics.

2. Revocable Living Trust

A revocable living trust is one of the most powerful tools for unmarried couples. It offers two major advantages over a will alone.

It avoids probate. Property held in a trust passes directly to your beneficiaries without going through court. This means no public record, no court supervision, and no opportunity for family members to intervene in the process.

It is harder to contest. While any document can be challenged, trusts are generally more difficult to overturn than wills. The trust operates during your lifetime, which helps establish that you were competent when you created it and that the arrangements reflect your genuine wishes.

You transfer assets into the trust during your lifetime, name your partner as the beneficiary, and designate a successor trustee to manage the distribution. For a deeper look at how trusts work, read our revocable living trust guide.

3. Durable Financial Power of Attorney

What happens if you become incapacitated and cannot manage your own finances? Without a durable financial power of attorney (POA), your partner has no legal authority to pay your bills, access your bank accounts, manage your investments, or handle your financial obligations.

Someone would need to petition the court for guardianship or conservatorship to manage your affairs. That someone might be a family member who does not know your wishes or support your relationship.

A durable financial POA names your partner as your agent with authority to act on your behalf if you cannot act for yourself. "Durable" means the authority survives your incapacity, which is exactly when you need it most.

Learn more about how power of attorney works in our state-specific guides: power of attorney (FL | CA | TX | OH).

4. Healthcare Power of Attorney / Healthcare Proxy

This is arguably the most urgent document for unmarried couples. Without a healthcare power of attorney (also called a healthcare proxy), your partner has zero standing to make medical decisions for you.

If you are in an accident, have a stroke, or become unable to communicate, hospitals will turn to the default legal hierarchy for decision-making authority:

1. Legal spouse
2. Adult children
3. Parents
4. Adult siblings
5. Other relatives

Your partner is not on this list. That means your parents or siblings would make decisions about your medical care, even if you and your partner discussed your wishes in detail. Even if your family members have not spoken to you in years.

A healthcare POA puts your partner in charge of your medical decisions when you cannot speak for yourself. For more details, see our healthcare directive guides (FL | CA | TX | OH).

5. Advance Healthcare Directive / Living Will

While a healthcare POA names who makes decisions, an advance healthcare directive (or living will) spells out what decisions you want made. This covers end-of-life care, life support, resuscitation preferences, organ donation, and other critical medical choices.

This document serves two purposes for unmarried couples. First, it gives your partner clear guidance about your wishes, reducing the emotional burden of making difficult decisions. Second, it provides written evidence of your intentions that can support your partner's authority if family members disagree.

6. HIPAA Authorization

Under federal HIPAA privacy rules, healthcare providers cannot share your medical information with anyone unless that person is authorized. A spouse is typically authorized by default. An unmarried partner is not.

Without a HIPAA authorization form, your partner may not be able to:

• Get updates on your condition from doctors or nurses
• Access your medical records
• Discuss treatment options with your healthcare team
• Pick up prescriptions on your behalf

A signed HIPAA authorization form gives your partner legal access to your medical information. This is a simple document, but it can make an enormous difference during a health crisis. Make sure copies are on file with your primary care physician, any specialists you see regularly, and the local hospital.

7. Cohabitation Agreement

A cohabitation agreement (sometimes called a domestic partnership agreement or non-marital agreement) addresses the financial and property aspects of your relationship. Think of it as a prenuptial agreement for unmarried couples.

A good cohabitation agreement covers:

• Property ownership: Who owns what, and how is jointly acquired property divided?
• Expense sharing: How do you split rent, mortgage, utilities, and other costs?
• Debt responsibility: Who is responsible for which debts?
• Separation terms: If the relationship ends, how is property divided?
• Financial support: Are there any support obligations?

This agreement protects both partners. Without one, disputes about property ownership can end up in court, and the outcome may not reflect what either partner intended or contributed.

Healthcare Decisions: The Most Urgent Gap

Of all the rights unmarried couples lack, healthcare decision-making is the most time-sensitive. Property and inheritance issues can be resolved after the fact (even if imperfectly). Medical crises cannot wait.

Real-World Consequences

Stories of unmarried partners being denied hospital access or medical decision-making authority are not rare. Consider these scenarios:

Emergency room situation. Your partner is in a serious accident. You rush to the hospital. Staff ask if you are a family member. You say you are their partner. Without documentation, the hospital may limit your involvement. Your partner's estranged parents arrive and take over medical decisions.

End-of-life care. Your partner is on life support. You know they would not want to be kept alive artificially. You discussed it many times. But without a healthcare POA naming you as the decision-maker and an advance directive documenting their wishes, the legal next-of-kin makes the call.

Long-term incapacity. Your partner develops dementia. Over months and years, they lose the ability to manage daily activities. Without a durable POA and healthcare proxy, you may need to petition the court for guardianship, an expensive and public process with no guaranteed outcome.

What to Do Right Now

If you do nothing else after reading this guide, do these three things:

1. Sign a healthcare POA naming each other as medical decision-makers
2. Complete HIPAA authorization forms and give copies to your doctors
3. Write advance directives documenting your end-of-life wishes

These three documents together cost very little and can prevent the worst-case healthcare scenarios.

Property Protection Strategies

Unmarried couples have several ways to own property together that provide protection without relying on a will.

Joint Tenancy with Right of Survivorship (JTWROS)

When you own property as joint tenants with right of survivorship, both partners own equal shares. When one partner dies, the surviving partner automatically inherits the deceased partner's share. No probate required. No will needed for this asset.

Best for: Couples who contribute equally to the property and want automatic transfer to the survivor.

Watch out for: Both partners must own equal shares. If one partner contributed significantly more to the purchase price, this arrangement might not feel fair, and it could have gift tax implications.

Tenants in Common

Tenants in common each own a defined share of the property (50/50, 60/40, 70/30, or any split). When one partner dies, their share passes through their estate according to their will or trust.

Best for: Couples with unequal contributions who want ownership to reflect what each person put in.

Watch out for: The deceased partner's share goes through probate unless it is held in a trust. Family members could potentially claim the share if there is no will.

Transfer on Death (TOD) Deeds

More than 30 states now allow transfer on death deeds for real property. A TOD deed lets you name a beneficiary who automatically receives the property when you die, without probate. You keep full ownership and control during your lifetime. You can revoke or change the beneficiary at any time.

Best for: Couples who want to avoid probate on real estate without the cost or complexity of a trust.

Payable on Death (POD) Accounts

Bank accounts, savings accounts, and certificates of deposit can be set up with a payable on death designation. When the account holder dies, the funds transfer directly to the named beneficiary. No probate, no will needed for these assets.

Best for: Ensuring your partner has immediate access to funds after your death (since probate can freeze assets for months).

Tax Differences That Cost You Money

The tax code treats married and unmarried couples very differently. Understanding these differences helps you plan around them.

No Unlimited Marital Deduction

Married couples can transfer unlimited assets to each other during life or at death without any gift or estate tax. Unmarried couples get no such benefit.

For 2025, the federal estate tax exemption is $13.99 million per person. Below that threshold, this is not an issue for most couples. But if your combined estate exceeds the exemption amount, or if the exemption decreases in the future (it is set to drop roughly in half after 2025 unless Congress acts), the lack of a marital deduction becomes a real cost.

No Portability

When a married person dies without using their full estate tax exemption, the unused portion transfers to the surviving spouse. This is called portability. It effectively doubles the amount a married couple can pass on tax-free.

Unmarried couples get no portability. When one partner dies, any unused exemption is lost.

Higher Inheritance Tax Rates

Several states impose inheritance tax, and the rates depend on the relationship between the deceased and the beneficiary. Spouses are typically exempt or pay the lowest rate. Non-family beneficiaries (which is how unmarried partners are classified) pay the highest rates, often 15% to 18%.

Gift Tax Limitations

Married couples can give each other unlimited gifts with no tax consequences. Unmarried couples are limited to the annual gift tax exclusion: $19,000 per recipient for 2025. Gifts above that amount count against the lifetime estate and gift tax exemption.

This matters for everyday financial moves. If one partner pays the mortgage on a jointly owned home, makes a large transfer to the other partner's account, or adds the other partner to a deed, these could be considered taxable gifts.

Inherited Retirement Accounts

Under the SECURE Act, non-spouse beneficiaries must withdraw all funds from an inherited IRA within 10 years. Spousal beneficiaries can roll the inherited IRA into their own IRA and spread withdrawals over their lifetime.

This 10-year rule can create a significant tax hit. If your partner inherits a large IRA, they may be forced to take distributions that push them into a higher tax bracket.

Domestic Partnerships and Civil Unions

Some states offer domestic partnership or civil union registrations that provide state-level legal protections for unmarried couples.

Where Domestic Partnerships Are Available

As of 2025, the following jurisdictions offer domestic partnership registrations with broad legal protections:

• California
• District of Columbia
• Maine
• Nevada
• Oregon
• Washington
• Wisconsin

California's registered domestic partnership provides nearly all the same state-level rights as marriage, including community property protections, intestacy rights, healthcare decision-making authority, and the right to an elective share.

The Federal Gap

Here is the critical limitation: domestic partnerships are not recognized under federal law. This means domestic partners do not receive:

• Federal tax benefits (no marital deduction, no joint filing, no portability)
• Social Security survivor benefits
• Immigration rights
• ERISA protections for employer-sponsored retirement plans
• Federal veterans' benefits

Even if you register as domestic partners in a state that offers the status, you still need all seven documents listed above to fill the gaps that federal law does not cover.

Should You Register?

If you live in a state that offers domestic partnership and marriage is not right for your situation, registering is generally worth it. The state-level protections, especially around healthcare decisions and intestacy, provide an extra layer of security. Just understand that registration alone is not a substitute for a full estate plan.

Your Action Steps

Here is a practical checklist to protect your partner and yourself. You do not need to do everything at once, but you should start now.

This Week

• Sign healthcare POAs naming each other as medical decision-makers
• Complete HIPAA authorization forms and distribute to your doctors and local hospital
• Write advance directives documenting your medical and end-of-life wishes

This Month

• Create wills that specifically name your partner as a beneficiary
• Sign durable financial POAs giving each other authority over financial matters
• Review all beneficiary designations on retirement accounts, life insurance, and bank accounts to ensure your partner is named
• Set up POD designations on bank accounts so your partner has immediate access to funds

This Quarter

• Consider a revocable living trust to avoid probate and reduce the risk of family contests
• Review property titles and consider JTWROS, TOD deeds, or holding property in a trust
• Draft a cohabitation agreement covering property, expenses, and financial obligations
• Consult an estate planning attorney who has experience with unmarried couples and non-traditional families

Annually

• Review and update all documents as your relationship, finances, or family situation changes
• Confirm beneficiary designations have not been changed or reverted by financial institutions
• Update your will and trust to reflect new assets or changes in your wishes

The Bottom Line

The legal system was built around marriage. If you are not married, you start with no protections and must build them yourself. That is not fair, but it is the reality.

The good news is that with the right documents and strategies, you can close almost every gap. A will or trust ensures your partner inherits. Powers of attorney give your partner authority during a health or financial crisis. HIPAA authorizations keep your partner in the loop on medical information. Property titling and beneficiary designations bypass probate entirely.

The worst thing you can do is nothing. Every day without these documents is a day your partner is legally unprotected. Start with the healthcare documents this week. Build from there. The peace of mind you both gain is worth every minute and dollar you invest.
