Cases involving enquiries about birth/biological parents and decisions to rectify a birth certificate often require a great deal of care and consideration. They can upend established family history and introduce unexpected  narratives about unplanned pregnancy,  love affairs, failed relationships, adoption, loss and death. They can uncover fertility fraud or even egg, sperm or embryo mix-ups at fertility clinics. They can also create complex issues with genetic relatives and legal family members, intermingled with complex emotional dynamics (shock, anger, shame, grief, fear, rejection, happiness and acceptance).
