If you do not make a prenuptial agreement, state laws will determine who owns the property that you acquire during your marriage, as well as what happens to that property at divorce or death. In the absence of a prenup stating otherwise, a spouse usually has the right to:
Share ownership of property acquired during marriage, with the expectation that the property will be divided between the spouses in the event of a divorce or at death.
Incur debts during marriage that the other spouse may have to pay for, and share in the management and control of any marital or community property, sometimes including the right to sell it or give it away.
