If you and your spouse file married filing separately, it is not your problem if someone else tries to claim her as a dependent--it will be their problem. It will have no effect on you. You have no control over other people's choices or poor/incorrect decisions. You can only file a joint return if she AGREES to file jointly with you. If she will not file a joint return with you then your only option is to file married filing separately. If YOU file a joint return without her agreement, then you will be the one filing a fraudulent return.
