I am a single mom of an 18-month-old son. I have never been married. His father's name is on the birth certificate, my my son lives solely with me. His father helps financially and sees him often. I am considering moving out of the state down the road, should a certain item pan out. Do I need to get my son's father's written consent before doing so? I don't want to do anything illegal. I just want to know what the law is if the custodial parent has never wed the child's father. I live in New Jersey.
