Question: Article: Most people are aware of what the adoption process is because it has become rather common in our society. Adoption is where a child is legally placed with guardians or parents (or perhaps a single parent) other than the birth mother or father. Once an adoption is finalized, all parental rights are turned over to the adoptive parents and there is no legal difference between adoptive parents and natural birth parents. There are generally two types of adoption, which are closed adoption and open adoption. When an adopted person has access to his or her adoption file and original records, it is referred to as an open adoption. The term is also used to describe any contact that may be between the adoptive family, the birth parents, and the adopted child. The level of openness can change greatly in such contact depending on each individual relationship. There can be indirect contact between the natural birth parents and the child through the form of letters and photographs, or there can be actual physical contact. A semi-open adoption is where the birth parents may have contact with the adoptive parents before the birth of the child, either once or several times. After the birth there is no more contact. A semi-open adoption may remain as it is or it can become either open or closed. A closed adoption is where only the medical and historical information about the biological parents is given to the adoptive family. Typically, the birth and adoptive parents do not know each other's identities. The record of the birth parents is kept sealed . A closed adoption is usually only effective in the adoption of babies. The adoption of an older child who already knows his or her birth parents cannot be kept closed.
