Legal Question in Real Estate Law in California

I would say that this sounds like a case of promissory fraud and that with good factual evidence and proper representation, your chance of having the transfer set aside are pretty good. You should ask your divorce attorney whether he/she can handle this within the divorce proceedings or whether this should be raised in a separate court action with a specialist in fraud matters representing you.

It is very likely that the quitclaim deed will be ignored or voided by the divorce court, but you are going to need a good divorce lawyer to make that happen. I strongly recommend you find a good lawyer immediately.
