Is it true that annulment papers don't haveto be served by police?

Question

I have two experienced professionlas telling me different things: one says that ONLY police serves the annulment papers to my spouse, and another says that these papers can be sent by mail, and if no one responds in 30 days, my plea would be approved.
Do you know anything about it?

Answer 1

They are served by police, sheriff department, or an independant server.
