court procedure

Hi My wife desserted me and living with her parents in a different state since more than a year. Now suddenly local police approached my residence and servered a court notice which is asking me to appear in the mentioned date to respond to the petition filed by my wife. It has got no other details. This has come from family court. Can anybody tell me what kind of petition it could be which is served through police. (divorce, DV, CRPC 125 etc). I am yet to engage a local lawyer to get a copy Thank you
