Parentage is the legal relationship between a child and a parent. Parentage needs to be established before child support, parenting time, or decision-making power can be ordered.
A parent has the right to parenting time (visitation) with a child. They can also ask for decision-making power over the child. They must also pay child support.
A VAP is a legal form that establishes a legal relationship between a parent and a child. Both parents must sign the form. Once it is signed, it is very hard to undo.
