Who owns what in a marriage in the United States?
In most US states spouses own what is in their name and a court divides marital property fairly on divorce. Nine states have a community property system, where property acquired during the marriage is joint.

What applies by default
In most states, property belongs to the spouse in whose name it is, and there is no automatic joint ownership. In the community property states, which include Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin, property acquired during the marriage is joint.
When the marriage ends in divorce
Most states use equitable distribution, where a court divides marital property fairly, not always equally. Community property states generally divide community property equally, or in a way the state law specifies.
A marriage contract
Prenuptial agreements are generally enforceable if they are in writing, voluntary and fair, with proper disclosure. Details differ by state.
What stays your own, and gifts
Property from before the marriage and gifts and inheritances are generally separate, but can become marital if mixed with marital property.
If one spouse is a foreigner
Moving between states can change which rules apply, so a couple who moves should check the rules of the new state.
What to watch for
- Alaska lets spouses opt in to a community property system by agreement.
Understand the legal system first
The United States belongs to the Common law family. Family law grows out of the legal tradition, so it helps to know how the system works.
