MBE Rules · Community Property
Nonmarital Cohabitation
Marvin v. Marvin
The rule
Unmarried cohabitants have no community property rights; express or implied contracts between them are enforced unless founded on meretricious sexual services, with quantum meruit and constructive trust available.
In plain English
Unmarried couples living together do not have the same community property rights as married couples. They can enforce contracts between them, but any agreement based solely on sexual services is not enforceable, although they may still recover value through other legal theories like quantum meruit or constructive trust.
Worked example
Alice and Bob have been living together for three years and have a written agreement that they will share expenses equally. When they split up, Alice tries to enforce the agreement to recover her half of the rent. The court upholds the contract since it is not based on sexual services, allowing Alice to recover her share.
Memory hook
Cohabitation without marriage means no community property, but contracts can still hold water.
The trap
Exams may present scenarios where students mistakenly assume cohabiting partners have community property rights, leading to incorrect conclusions about asset division.
How examiners test it
Questions often involve fact patterns where cohabiting partners have disputes over property or contracts, testing the understanding of enforceability and the limits of rights in nonmarital relationships.
