Adoption documents are legal documents used to establish a legal parent-child relationship between an adoptive parent and an adopted child. These documents include the adoption petition, the adoption order, the adoption decree, the adoption certificate, and the adoption agreement. The adoption petition is the initial document that is filed with the court to begin the adoption process. The adoption order is the court’s decision to grant the adoption. The adoption decree is the final document that legally establishes the adoptive parent-child relationship. The adoption certificate is a document issued by the court that serves as proof of the adoption. The adoption agreement is a contract between the adoptive parent and the birth parent that outlines the rights and responsibilities of each party.
