Me and my sons father live in the same town in az we are not together we have nothing signed for the courts I am still trying 2 serve him I want to take my son to wa to visit my sister for 4 days the father is saying he has the right to say I can't take him is this true?

No, unless there is any custody order in place, neither one of you have a right to tell the other what they can or can't do with their child

If he lives in town and you know where, what is the issue with service ? How long have you been trying ?

For a few weeks now I finally handed him the paperwork and told him to go sign it in front of the court clerk so we can get it going but he has not responded. All I want to do is go to WA for 4 days! I'm OK with him taking him places but he just doesn't want me happy so anything he can do he will while he's off with his girlfriend and her kids
