You may change your mind at any time prior to signing consent papers. See Consent to Adoption
After papers are signed, in private adoptions, you have 30 calendar days after signing the consent to change your mind.
However, if you signed a Waiver of the Right to Revoke Consent in front of a judge, your consent is immediately irrevocable, and you cannot change your mind.
If you signed a Waiver of the Right to Revoke Consent in front of an Adoption Service Provider , you can change your mind until the Waiver becomes final at the close of the next business day after signing.
