Paton began Orphan Voyage, and into the 1970s with the creation of ALMA, International Soundex Reunion Registry, Yesterday's Children, Concerned United Birthparents, Triadoption Library, and dozens of other local search and reunion organizations, there has been a grass roots support system in place for those seeking information and reunion with family. Reunion registries were designed so adoptees and their birth parents, siblings or other family members can locate one another at little or no cost. In these mutual consent registries, both parties must have registered in order for there to be a match. Most require the adoptee to be at least 18 years old. Though they did not exist until late in the 20th century, today there are many World Wide Web pages, chat rooms, and other online resources that offer search information, registration and support. From the very beginning, there have been Search Angels who help adoptees, siblings and birth families locate their relatives for free. Usually, these are persons personally touched by adoption who do not feel anyone should be charged a fee to get information about themselves or their family. Laws are ever changing and in a few states of the US, a few provinces in Canada, the UK and Australia there are now various forms of open records giving adoptees and birth family members access to information in their files and on each other. 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.
