I have filed for divorce and sent the papers certified mail, return receipt requested to my ex at his workplace. He works at a large company with a central mail room so, instead of sending the letter up to him, someone who was “certified to sign for mail” stamped the card and sent it back. Is that sufficient to attach to the affidavit for service by certified mail? If I have to serve him again do I need to have additional copies of the summons filled out by the clerk of court or can I just make copies of the paperwork that I have? Thanks so much!
