Legal Question in Family Law in California

You would definitely not have a right to half. Separate property AND any financial proceeds that come from it remain separate property unless commuted into community property by gift, comingling beyond the ability to trace, etc. So the property and the rents and the payments made with the rents were all your husband's separate property, as are the proceeds of the sale. Depending on all the facts and details, the best you might be able to do is cobble together a claim for reimbursement of any community assets that went into the property during the marriage. For example, if wages or other earnings from work during the marriage were used for improvements to the property. If he actively managed the property, there may also be some claim for his labor as a community contribution to the separate property, but that kind of claim is usually reserved for things like a business that one spouse started before marriage but grew and prospered due to the work of the spouse as an employee/owner over the years.
