Greetings. If you agreed to the issues in a properly drafted and executed separation agreement, no she cannot do anything about the issues of alimony and equitable distribution. If you did not, sure she can sue.
She did not sign the divorce papers, but probably signed to accept them being served on her, right? No, it is not too late for her to sue you. She can sue you until you have the divorce judgment signed by the judge in your hand. Best of luck.
