Estate Issues

need help: I am in a similar situation in California. After the divorce was finalized long time ago (1996), the house was rented out.  But, I let my ex moved back in for the last 3 years because my ex divorced again and is willing to pay the mortgage and my youngest was under 18 years old.The youngest child is now over 18 years old and I want to get my share out to give my grown sons money for college but my ex will not talk to me. Please tell me how to proceed. We did the divorce ourself years ago amicably. I need to know what form to file and where to file it. I have checked the self-help divorce books, but I don't find much talk about this. My name is still  on the deed, and I get a notice everymonth from the bank when the mortgage payment is made. My ex has a very good professional career, makes much more money than I do now, so it's not like I try to squeeze anyone. The property is awarded to us as "teneants-in-common, 50/50, undivided interest to each" as said in the final divorce Judgement.  I would appreciate all your help. I'll  try to do it myself if all possible.

In the divorce I did let him have everything so that the kids would have it. But, he has never had me sign anything to remove my name from the warranty deeds for the house and land.
As for things that are mine going to his new wife, I am not sure what is considered mine since in the divorce I gave everything to him. But my question is, do I have any right to go back and fight for a proper division of property since I feel like I left everything for my kids and that he is not seeing to it that that agreement is followed through on. I feel like I left everything under false pretenses. If I had known he would turn into a jerk and his new wife urging him to be that jerk I would not have left anything. I would have had everything divided in half and left my half to my children in way of a savings account or a trust.
I just don't know what I can do to protect what I left for my children. I don't want anything from the house and I don't want the house or land. I just want my children to get what is rightfully theirs. And talking to their dad about this is not an option because he seems to be brainwashed by this girl. He doesn't even listen to his kids anymore. He takes her side against them everytime.

Was there any division of property ordered by the Judge and was it included in the divorce Decree? If it wasn't, you could consult a lawyer if it is possible to file a separate petition for the division of property, and if it was, you still have your name on the deeds. He cannot sell, or put it in his wife's name without your signature.
More likely she would inherit his half, while the other half would still belong to you if there's no will stating differently.

It may depend on your state and what the divorce agreement states. The house was something that was not purchased within the time frame of his curtain marriage, so it will fall on divorce docs and state laws. You both may want to do a living will on the house for your children.

Not sure I follow here.  Why would anything of yours go to his new wife?  Do you both have wills?
