Moving In Together? Here's What Happens to Your Stuff If One of You Dies
Living together doesn't give your partner any legal rights over your estate. Here's what unmarried couples need to know — and do — to actually protect each other.

Moving in together is a big deal. You're sharing space, splitting rent, building a life together. It feels like a serious commitment — because it is.
It's just not a legal one. And that distinction matters more than you'd think.
The law does not recognize your relationship
Here's the hard truth: in every U.S. state, an unmarried partner has no automatic legal right to inherit anything from you. Not your apartment. Not your savings. Not the furniture you bought together. Not the dog you both love.
If you die without a will, your estate goes through intestacy — the state's default formula. That formula goes to your legal next of kin: parents, siblings, more distant relatives if necessary. Your partner gets nothing, regardless of how long you've been together, how serious you are, or how intertwined your lives have become.
This isn't an edge case or a technicality. It's the default. And it catches couples off guard more often than you'd think.
What 'cohabitation' means legally (not much)
You might assume that living together for long enough grants legal rights — the concept of 'common law marriage.' Common law marriage is recognized in only a handful of states (Colorado, Iowa, Kansas, Montana, New Hampshire, Oklahoma, Rhode Island, South Carolina, Texas, Utah, and DC — and even in those states, the requirements are strict).
If you don't live in one of those states, the length of your relationship is irrelevant. Five years together is legally the same as five months. Without formal legal recognition, your partner has no claim.

The simplest fix: make a will
A will that explicitly names your partner as your beneficiary changes this completely. You're overriding the default and replacing it with your actual wishes.
It doesn't matter that you're not married. Wills are valid for any beneficiary you choose — partners, friends, charities, anyone. You just have to actually write it down and execute it properly.
A basic will naming your partner as primary beneficiary takes about fifteen minutes to create. It's one of the more direct acts of care you can do for someone you live with.
Think about the things you co-own
When you move in together, you start acquiring things jointly — or things get complicated. The couch you bought together. The security deposit in your name. The streaming subscriptions, the shared grocery account, the lease.
A will handles personal property. But some assets are structured in ways that bypass your will entirely. Bank accounts with joint ownership or payable-on-death designations transfer automatically. Life insurance and retirement accounts go to whoever is named as beneficiary on those accounts.
Review all of those. Update your beneficiary designations if your partner isn't already named. This is especially important for things like life insurance — if your policy still names a parent from when you were 22, that's where it goes.
What about the apartment?
If the lease is in your name and you die, your partner doesn't automatically get the right to stay. Your estate handles the lease — meaning your executor does. In practice, landlords vary on how they handle this, but legally your partner has no guaranteed right to remain without a separate agreement.
If you own property together, the way you hold title matters enormously. 'Tenants in common' means each person owns a share that goes through their estate — so your partner could end up co-owning your apartment with your parents. 'Joint tenancy with right of survivorship' means ownership passes automatically to the surviving partner, bypassing your will entirely.
Talk to a real estate attorney when you're buying together. For renters, a will with explicit instructions about your wishes for shared belongings is a good start.
Consider a cohabitation agreement
Some couples moving in together create a cohabitation agreement — a legal contract that spells out how you'll handle shared finances, property, and what happens if you split up or one of you dies.
These aren't common, but they're worth knowing about. They're especially useful if one partner is contributing significantly more financially, if you're making major joint purchases, or if you want more protection than a will alone provides.
A family law attorney can draft one. Think of it as a prenup for couples who aren't getting married — it handles the practical questions that love alone doesn't answer.
Healthcare is another gap
Your will handles what happens after you die. But what if you're in an accident and incapacitated? Who makes medical decisions for you?
By default, that's your next of kin — your parents, your siblings. Not your partner.
A healthcare directive (also called a medical power of attorney) lets you explicitly designate your partner as the person who speaks for you medically if you can't speak for yourself. Without it, your partner could be excluded from conversations about your care while your estranged family members make decisions.
This is a document worth creating at the same time as your will. They're complementary, and together they cover the situations where the absence of legal marriage status actually shows up.
The time to do this is now
Moving in together is a natural trigger. You're already making decisions together, signing leases together, buying things together. Spending thirty minutes on a will is one more decision that reflects how seriously you're taking this.
You don't need to be married for your partner to matter legally. You just need to write it down.
