My wife has changed the locks on the doors, said she has filed for divorce and locked myself and my 17 year old daughter out who starts school tomorrow.
File TRO and/or check on divorce filing (standing order in most divorce cases - parties cannot use self-help or in contempt of court - check with clerk and hire attorney)
It would be smart to hire a lawyer right now. Everything may take a while to fix, but it can't get fixed until a court case is filed.
