Legal Question in Real Estate Law in California

Ownership, and therefore the right to the net proceeds of sale, is determined by whose name(s) is/are on the title, not who lives in it. Therefore, I'd say the sale proceeds, after payoff of liens, taxes and broker fees (if any) would belong to your husband and his father. This assumes there is no additional agreement between your husband and his father, and that your father received his interest as a gift, which sounds like the situation.......but they may recall, or have written evidence of, a different understanding back in 2004. To further complicate the situation, you as the wife of a co-owner MAY have acquired a little interest in the mobile home IF community funds, or your own separate funds, were ever used to pay off financing on it or to make substantial improvements.
