Many people think of service of process as a game of legal freeze tag. The movies give the impression that you have to actually take papers that are handed to you, or get tagged or touched by the server, in order to be served. In the real world, it’s not that tricky. Your wife has the papers and actual notice of the proceeding, so she needs to act to protect herself. A family law attorney can help.
Best of luck to you.
