Some states have confidential intermediary systems. This often requires a person to petition the court to view the sealed adoption records, then the intermediary conducts a search similar to that of a private investigator. This can be either a search for the birth mother at the request of the adoptee, or vice versa. Quite often, in the many years which have passed since the adoptee was born, a birth mother or female adoptee has both moved to another address, and married or remarried resulting in a change of her surname. While this can make the search difficult and time consuming, a marriage certificate may provide the needed clue as to the person's whereabouts. If and when the intermediary is able to contact the birth mother (or adoptee), she is informed that her adopted child (or birth mother) is inquiring about her. In the few states that have open adoption records, should this party indicate that he or she does not want to be contacted, by law, the information would not be given out. Upon completion of the search in which the birth mother agrees to be contacted, the intermediary usually sends the adoptee the official unamended birth certificate obtained from the court. The adoptive parents' application to an adoption agency remains confidential, however.
Most open adoptions lie somewhere in the middle, according to Grotevant and McRoy, exchanging letters, pictures, and phone calls, and having face-to-face meetings once or twice a year. Whatever their situation, many families report that relatives and friends condemn openness, and voice fears that the arrangement will make the birth parent want the child back.
