How long do I have on the statute of limitations for division of assets?

There is no statute of limitation on this matter.. you are already in court..file a motion in the court to enforce the divorce judgment and claim 1/2 of any extra he receive (if he received in against the terms of the divorce judgment).

If a Judgment has been entered then the court must have retained jurisdiction over this asset or the property division for you to be able to go back now and request any modification. The only other avenue is if the asset was not disclosed or known at the time of the Judgment. Under those circumstances, the case can be reopened. You should consult a family law attorney to review all of the facts and documents and advise you.

If the judgment was complied with, I doubt that there is anything you can do. Did the house sell recently? If it wasn't complied with and the sale was recent, then you may be able to go back and ask for the order to be complied with. If the judgment was complied with, you are out of luck.
