Adoption is the legal process by which the parent-child relationship between two people is terminated by the court and a new person is legally decreed to be the parent of another. Adoptions can be pursued whether the “child” is still a minor under 18, or whether they are an adult. The proceedings required vary depending on the circumstances. When an adoption is finalized, the new parent is vested with all the rights and relationships that a natural parent would have had with the child, and the child obtains all the same rights they would have had if they were the biological child of the new parent. This can be particularly important in determining inheritance and other rights.
