Transmutation — Writing Required After 1985

Transmutation refers to the process of changing the character of property from community property (CP) to separate property (SP) or vice versa. Since January 1, 1985, any such change must be documented in writing and include a clear declaration from the spouse whose rights are being affected.

Hannah and Jake are married and own a house together as community property. In 2020, Hannah verbally tells Jake that she wants to change the house to her separate property, but they never put anything in writing. Later, Jake tries to claim half of the house in a divorce, and the court finds that the transmutation was invalid due to the lack of a written agreement.

No writing, no transmutation—keep it clear and documented!

Exams often present scenarios where a verbal agreement is made between spouses, leading students to mistakenly believe that the transmutation is valid without written documentation.

Questions typically involve a fact pattern where one spouse claims a change in property character without written consent, testing the candidate's understanding of the writing requirement for valid transmutations.
