My ex boyfriend ask to see our son two days ago. Which my son has lived with me his whole life. Hes 17 months old. WE have never been to court for any custody hearing or anything. Well my ex told me that he wasnt bringing him back home cause he could keep him if he wanted too because there is no law saying that he cannot. I want my son back what do i do? Can he just keep him?

Has your boyfriend signed acknoledgement of paternity? If not has paternity been established? Is there a custody order in place? If not then dad could getr in trouble for keeping him.

yes he has sign the paternity and the signed his birth certificate and down all that. But there is no custody order.

What state are you in? Normally, unmarried parents do not have equal rights to children. If you and he never married, he has to go to court to establish visitation rights. Unmarried mother's have far greater rights to children than do the fathers.

if you are not married and were not married and there is no custody agreement he technically has the same rights to the child as you do. My brother took his kids out of my ex SIL's house at nighttime and drove them across state lines and created primary residence with the court system in my state. It was not considered kidnapping or anything because no temp. custody agreement was in place at the time. I would go to court immediatly and set up temp.custody with visitation that way you and the child are protected

In some states if the parents are unmarried and there is no custody order to the contrary, the MOTHER has full custody of the child. The father would have no rights and have to turn the child over to the mom.
Go and try to pick your son up. IF he refuses call the police. Ask the police to make him give you back your son.
The ex-boyfriend will get mad, but all he has to do is take you to court and a visitation/custody agreement will have to be worked out.
