回复：In CA law, He owns this property. Does not matter how much p

I've already told you what you said is NOT California law. If you do not want to read case laws, go read family code section 2640 and 2641.

If the house value is lower than the purchase price, which may have made you believe that a straight Moore calculation will not get you anything, there are other ways to deal with it as this is a common problem in california today due to the house market downturn. One way is to argue Pereira/Van Camp interest in the house. The other way is to stipulate a later date to sell the house when the price is up. Only a creative attorney could help you to protect your interest.
