Living with someone else changes the rules. When a roommate stops paying, a partner won't move out, or a guest you welcomed for a week is still on your couch months later, you're often caught between landlord-tenant law, your lease, and your own relationships. This section walks through the situations that come up when people share a home, so you can figure out what kind of problem you actually have before you act.

The hardest part is usually a single question: is this person a tenant, a subtenant, a co-tenant, or just a guest? That label decides almost everything that follows, and the answer turns on facts like whether they pay rent, how long they've stayed, and whether they're on the lease. Because these definitions and the steps to remove someone are set by state and local law, the detailed articles here fill in what your jurisdiction actually requires.

Removing Someone Who Won't Leave

Whether it's a roommate, an adult child, an ex, a spouse in a house you own, or a long-term houseguest, you generally cannot just change the locks or move their belongings to the curb. That's known as a self-help eviction, and most states prohibit it even against someone who isn't on the lease. Instead, the law usually requires a formal process.

  • People who have established residency often must be removed through a court process such as an unlawful detainer or ejectment action, ending with a writ of possession that only law enforcement can carry out.
  • A true guest with no tenancy may sometimes be removed more quickly, but the line between guest and occupant is blurry and varies widely by state and city.
  • Family and romantic relationships add layers of their own, especially with marriage, shared property, or children involved.

Because the wrong move can expose you to liability or even claims of violating someone's right to quiet enjoyment, this is an area where a short consultation with a tenant lawyer or legal aid office is often worth it.

Who Owes What for the Rent

Money disputes are the other big source of roommate conflict. If a co-tenant won't pay their share, pays chronically late, or moves out and leaves you covering the gap, your options depend on your lease and your state's rules. Many leases make co-tenants jointly and severally liable, meaning the landlord can pursue any one of you for the full rent regardless of your private arrangement.

  • You may be able to sue a roommate in small claims court for their unpaid share, though collecting is a separate challenge.
  • If you're renting to a subtenant, you may have landlord-like duties yourself, including the implied warranty of habitability and the duty to mitigate damages.

Protecting Yourself Going Forward

Federal law, including the Fair Housing Act, limits how housing decisions can be made, and those protections can come into play even between roommates in some situations. Document agreements in writing, keep records of payments, and read your lease closely. When the stakes are high, an eviction on your record, a large unpaid balance, or a contested removal, getting advice tailored to your state is the safest path.
