Parent running / avoiding legal paperwork?

my wife and her childrens father have joint custody and he completely violated the terms so she filed to have parenting time changed but he is running from letting her serve him the paperwork and he has no address due to the fact that he lives between his mother and his current girlfriend. we informed a sheriff who tried to serve him the paperwork himself but he was unable to locate him and told us unless there is a way to find him there is nothing they can do. there has to be a way to fix this that doesnt involve standing in front of their homes until they show up. anyone got any advice?


Answer:
Generally, where there is an existing case, notice of hearing need not be personally served on the respondent. Only the initial complaint requires personal service. The documents can be mailed to him, certified mail. If he resides at both addresses, send two copies to each address--one certified mail, signature required, and one first class mail. Failure to accept a certified mailing, assuming he is generally found at and receives mail at that address, does not equate to failure of service. He is deemed to have been served by mail even where he refuses to accept it.
Couple of ideas....if you can afford it have a private detective camp out. Might cost a bit but you don't have to do it! Second choice....does he hold a steady job? If so, go to his work, he will have to be there in order to keep the work and he will have to show up. Catch him there. That is cheapest, but again he has to have actually have a job. You don't say. I imagine that this takes a personal service to set the hearing, so you get kind of limited in how that can be attained. When we had to do it, we did finally have to 'camp out' and the boyfriend's apartment complex to catch the ex-wife.

It sucks, but good luck in whatever you try to do to get service done.
