Scenario.. have own bank account and paid for lotto ticket with own money. If i win is my wife entitled to it?

I think this depends on the state you live in. Is it a community property state? If so, half is hers if you bought the ticket while you were together. I am not sure what having you committed has to do with this all, but what reason would she have? She can if you are doing something that puts you or someone else at risk. So if you are....STOP! if not, then she would have no legal means to put you away. You are an adult and if you are truly not needing to be committed, a psychiatrist would see through any divorce plot. best bet, always tell the truth and be your self. If you are being the best person you can be and following the golden rule then you should have nothing to worry about. It is lying and deceiving that will get you in trouble in the end.
