In Re Marriage of Lucas

Summary

The spouses bought a home in joint tenancy using $6,351.57 of the wife's separate trust funds for the down payment and a community-obligation loan, and she later paid $2,962 of separate funds for improvements. The trial court awarded her a 75.58 percent separate interest based on tracing and the lack of donative intent. The Supreme Court reversed the residence ruling and remanded: the joint-title community presumption (now section 5110) can be rebutted only by an agreement or understanding between the spouses, not by source of funds or an undisclosed intent. If the home is community, she gets no reimbursement without an agreement. The court affirmed the ruling that the motorhome, titled in the wife's name alone without objection, was her separate property by gift of the husband's small community interest.

What it means for the financial analysis

For a home titled in joint tenancy, a tracing schedule showing separate funds in the down payment is not enough by itself, so the work should be paired with evidence of any agreement or understanding about preserving a separate interest. If such an agreement is found, the court said the Aufmuth formula (separate share equals down payment over purchase price, community share equals loan over purchase price, with appreciation shared pro rata) is the preferred method, and the case gives a worked example of that calculation. That formula was stated as guidance on remand, and later authority may have changed it.
