In U.S the most common form of adoption is by adopting a child by
stepparent. When this adoption process has fully completed, the
noncustodial parent will no longer hold the legal rights for the
child which will result in full responsibility and support for the
child. There are slightly different ways of obtaining the consent
depending on the state. Some state will require written agreement,
while others ask both of parents to appear at the court and file legal
adoption papers. Many states will allow various legal adoption forms
where parents should specify child’s personal information including
name, address, length of residence with parent and birth information.
Along with this form, there should be proving document such as
certificate, license and consent forms.
