Separate Property and Commingling in a New Mexico Divorce
In New Mexico, property owned before the marriage or received by gift or inheritance is separate property and is not divided, but the spouse claiming it must prove it, community funds can create a community interest in it, and the court can still reach it for support.
Separate property
Property a spouse owned before the marriage, and property received during the marriage by gift, bequest, devise or descent, is separate property under the Community Property Act (NMSA 1978, § 40-3-8), as is property designated separate by a written agreement or acquired after a decree of division. Separate property is not divided at divorce.
The Supreme Court on classification
Property takes its character as community or separate at the time and manner of acquisition, and personal property acquired during the marriage with community funds or pledged community credit is community property (Bustos v. Bustos).
Commingling and community contributions
When community funds are used to buy or improve separate property, the community can acquire an interest in it, and mixing separate and community money can make tracing hard. The spouse who claims property is separate must prove it.
Reaching separate property
Even separate property is not always out of reach: the court may allow either spouse a reasonable portion of the other spouse’s property as spousal support (NMSA 40-4-7(B)(1)) and may set apart property or income for the children’s maintenance and education (40-4-7(B)(3)).
Evidence that helps
Dated statements showing premarital balances, gift and inheritance documents and records tracing every transfer in or out of a separate account.
Keeping the right paperwork
Keep inherited and premarital funds in accounts in your name alone and keep records that trace them.
In the calculator
Enter premarital and inherited property as separate property in the New Mexico property division calculator so it stays out of the division.
