I already signed my divorce paper and ex husband attorney filed it but I got a second to sign a summons and complaint need to know why

Thank you for your question. It sounds like you received a summons and complaint with an acknowledgment of service. This needs to be signed so the court knows that you are aware that this action is moving forward. Without reviewing the documents that you are referring to, it is difficult to answer your question completely. I would suggest that you reach out to a family attorney to schedule a consultation so all of your questions can be answered.
