Best Estate Planning for Unmarried Couples in Maryland

If you're unmarried and living together in Maryland, your partner has zero legal right to inherit anything when you die. Maryland intestacy law treats unmarried partners as legal strangers — your assets default entirely to blood relatives, no matter how long you've been together or how intertwined your finances are. And any assets you do leave to your partner through a will trigger Maryland's 10% inheritance tax, because unmarried partners are classified as non-lineal heirs.

The best estate planning tool for unmarried couples in Maryland is one that addresses both problems simultaneously: building an inheritance framework that doesn't exist automatically, and minimizing the tax hit on every dollar that passes between you. The Maryland Basic Estate Planning Kit is designed around exactly this scenario — the dual-tax trap and the common law property rules that make Maryland uniquely hostile to unmarried couples.

Why Maryland Is Different

Most estate planning guides treat unmarried couples as a footnote. In Maryland, it's the central issue. Three rules collide to create a worst-case scenario:

No automatic inheritance. Under Maryland's common law property system, assets are owned by whoever holds title. There's no community property split. If your partner's name isn't on the deed, the bank account, or the investment — they get nothing when you die.

10% inheritance tax. Maryland's inheritance tax exempts spouses, parents, children, grandchildren, stepchildren, and siblings. Everyone else — including your unmarried partner of 30 years — pays a flat 10% on the clear market value of whatever they inherit. Leave your partner a $400,000 home? They owe $40,000 in inheritance tax before they can move in.

No healthcare decision-making authority. Without a Maryland Advance Directive naming your partner as your healthcare agent, they cannot make medical decisions or even access your medical records in an emergency. The hospital will defer to your next of kin — a parent, sibling, or adult child.

The Core Documents You Need

Reciprocal Wills

Each partner needs a last will and testament naming the other as primary beneficiary. Maryland requires two credible witnesses, and a Self-Proving Affidavit means the Orphans' Court accepts the will without calling witnesses to testify years later.

Without a will, Maryland intestacy law distributes your estate to: your surviving spouse (you don't have one), then children, then parents, then siblings. Your partner is not in the chain at any point.

Transfer-on-Death Deed

Maryland's new TOD Deed Act (effective October 1, 2026) lets homeowners pass real estate directly to a named beneficiary outside probate. This is transformative for unmarried couples — the home transfers immediately at death, bypassing the Orphans' Court entirely. The transfer is also exempt from Maryland transfer and recordation taxes.

The inheritance tax still applies to non-lineal heirs receiving property via TOD deed. But avoiding probate saves your partner months of delay and thousands in Register of Wills fees.

Financial and Healthcare Powers of Attorney

A durable financial power of attorney lets your partner manage your finances if you're incapacitated. A Maryland Advance Directive grants healthcare decision-making authority. Without these, your partner is shut out — legally, they're no different from a neighbor.

Strategies to Reduce the 10% Tax Hit

You can't eliminate Maryland's inheritance tax for an unmarried partner entirely, but you can reduce the taxable amount:

• Life insurance — proceeds paid to a named beneficiary are not subject to Maryland inheritance tax. A term life policy can replace the value lost to the 10% tax on other assets.
• Joint tenancy with right of survivorship — property held as JTWROS passes directly to the surviving owner outside probate. The inheritance tax may still apply to the decedent's proportional share, but it avoids probate fees and delays.
• Retirement account beneficiary designations — IRAs and 401(k)s pass directly to the named beneficiary and are not part of the probate estate. Ensure designations are current and coordinate with your will.
• Gift during lifetime — Maryland has no state gift tax. The federal annual gift tax exclusion is $19,000 per person (2026). Systematic gifting over several years can reduce the taxable estate.

Who This Is For

• Unmarried couples who own a home together or separately in Maryland
• Partners who have been together for years but have no legal documents in place
• Same-sex or opposite-sex couples who chose not to marry for personal, financial, or tax reasons
• Anyone whose partner would be classified as a non-lineal heir under Maryland law

Who This Is NOT For

• Married couples (spouses are automatically exempt from Maryland inheritance tax and have statutory inheritance rights)
• Couples whose combined assets are simple enough that a single beneficiary designation on a bank account covers everything
• Anyone who needs advice on prenuptial or postnuptial agreements (consult a family law attorney)

Frequently Asked Questions

Does domestic partnership registration protect us in Maryland?

Maryland does not have a statewide domestic partnership registry that confers inheritance rights. Some counties (Montgomery, Howard) offer domestic partnership registries, but these provide limited benefits — primarily hospital visitation and some employment benefits. They do not change your inheritance tax classification or grant automatic inheritance rights under state law.

Can we avoid the 10% inheritance tax entirely?

Not on assets that transfer at death to a non-lineal heir — the tax is structural. But life insurance proceeds paid to a named beneficiary are exempt from the inheritance tax, making life insurance the most direct workaround. You can also reduce the taxable estate through lifetime gifts.

What happens to our joint mortgage if one of us dies?

If you hold the property as Joint Tenants with Right of Survivorship, the surviving partner automatically owns the entire property. The mortgage obligation continues — the lender cannot call the loan due solely because of the co-borrower's death (federal Garn-St. Germain Act). If you hold as Tenants in Common, the deceased partner's share passes through their will or intestacy, which could mean your deceased partner's family now co-owns your home.

Is a revocable living trust better than a will for unmarried couples?

A revocable trust avoids probate entirely and keeps your asset distribution private (wills become public record when filed with the Register of Wills). For unmarried couples with real estate and substantial assets, a trust combined with a pour-over will is often the cleanest structure. However, trust assets passing to a non-lineal heir are still subject to the 10% inheritance tax.
