The Pennsylvania Affidavit of Custody and Gratuitous Keep is a legal document used to establish legal custody of a minor child. It is most commonly used when an unmarried mother wants to establish paternity, or when an unmarried father wants to establish legal custody of the child. This document is signed by both parties involved in the custody agreement and is notarized by a Notary Public. The Pennsylvania Affidavit of Custody and Gratuitous Keep can be used in two different ways depending on the situation. The first type is a Custody-Only Affidavit, which is used only to establish custody and does not establish legal rights or responsibilities for either parent. The second type is a Full Custody and Support Affidavit, which establishes both legal custody and establishes the financial obligations of both parents. The Pennsylvania Affidavit of Custody and Gratuitous Keep is a legally binding document and must be taken seriously by both parties involved. It is important that both parties understand the document before signing to ensure that all of their rights and responsibilities are respected.
