Hello, I am happy to assist you today.
Sorry to hear about your situation. You do have rights here.
Forging your name on the business documents is a serious criminal offense. A felony actually in most states. This you can report to the police by filing and incident report. Then the police and district attorney will decide whether to bring criminal charges, and you don't have to do anything more.
Well if you already filed for divorce, then you are in the right court to handle this. You don't need to file any other separate action. If he won't give your attorney his financial disclosures, then you should file a motion for contempt of court, and ask the judge to force him to do so. If not, the judge can actually send him to jail.
In terms of financial support for you, you should be able to get payments from him, including consideration of this new income that he has, and the judge will take into consideration all sorts of factors and decide how much is appropriate for you to receive.
If you own the house and he is living there, you have the right to ask him to leave. If he doesn't pay rent then he isn't a tenant, and just a guest, and you can ask him to leave. If he does not you can legally evict him. That's nuts that he is living there and making that much money and not contributing.
I think you will be ok, you just have to move forward quickly in the divorce proceeding and get yourself some checks coming in from him.
Let me know if you have any questions about this.
