I assume with the value of assets (at least this one asset), you've been dealing with attorneys in your divorce.
Your attorney is going to be VERY interested in this twist. More importantly, the judge is going to be more than interested. You may want to consider (discuss this with your attorney first) filing a police report for a violation of Penal Code section 470. The DMV has their own investigations division as well.
Forgery is a crime no matter how much money is at stake. Report it to the police, but I would get a copy of the transfer papers from DMV first to show them. And yes, see your lawyer about this. I do not know why you came to us instead of your own lawyer. He/she can petition the court to make HIM pay your lawyer for the time it takes. If you did NOT use a lawyer when you got the divorce, get one now.
