Buying a House With an Unmarried Partner

Published 2026-09-09 Last reviewed 2026-09-09 By Lisa C Hamilton, REALTOR®

Quick Answer

Unmarried partners can buy real estate together. But unlike married couples, they should be especially deliberate about ownership, mortgage liability, contributions, repairs, sale decisions, breakup, death and buyout rights. The mortgage and the title are separate documents, and both should be understood before closing.

Love Is Not an Ownership Agreement

Before buying, decide who contributes the down payment, the monthly payment, repairs and closing costs, and who owns what percentage.

Mortgage vs. Title

Someone can potentially be obligated on debt without the ownership arrangement being identical. Understand both documents.

What If You Break Up?

Nobody wants to discuss this. Discuss it anyway. Options may include selling, one buying the other out, refinancing, or continuing to co-own temporarily. A written co-ownership agreement can reduce later disputes.

What Happens at Death?

Estate planning matters. Do not assume an unmarried partner automatically receives the deceased owner's interest. Title and estate rules matter.

Lisa's Role

Lisa can help both buyers find and negotiate the home. Ownership and legal planning should involve qualified counsel.

Frequently Asked Questions

Can two unmarried people be on a mortgage?

Yes, potentially.

Does each need 50% ownership?

No. Title structure can vary.

Should we sign an agreement?

Legal counsel can explain why a co-ownership agreement may be valuable.
