When and how does transmutation or commingling occur? When using inheritance to purchase community property?

Los Angeles, CA |

I am currently in a divorce mediation. My ex used inheritance to help with the downpayment of our first home. Three years later we sold that home and with the money we made from that sale we purchased our current home which we have owned for 6 years. Both homes where titled as joint tenancy. Is she able to claim that she get the inheritance money back after some much time has passed, and we now own a different community property? When and how does transmutation or commingling occur?

This is a Family Code Section 2640 issue, not a transmutation or commingling issue. The houses were both community property. However, if your wife can trace the funds from her inheritance to the down payment on the 1st home (whose net sales proceeds went into the existing home), she will be able to recover those separate property funds, dollar for dollar (without interest or appreciation) before the community property balance is divided 50/50.

This answer does not create an attorney-client relationship.

Very Great, forgot about the code section.


The question is not of transmutation or commingling, but of tracing. If the inheritance money can be traced back to the inheritance, than that part will remain separate property. Any portion of it that has grown in the form of a capital gain, would be community property.

The short answer is that unless the some or all of the transactions occurred before approximately 1984, she can at least make a plausible claim, although she'll need to present evidence as to the source of the original money, and the tracing of the money through the various later transactions. Whether or not she has a good claim, with a high chance of success, depends on a bunch of facts, which you should review with an experienced family law attorney. Tracing/transmutation law is definitely NOT a "do it yourself" project, and to be able to mediate this issue usefully, you need legal advice as to what your best/worst case is if you go to court.
