When people build families using assisted reproductive technology– the use of donor gametes or a gestational carrier– fertility law can provide clarity and understanding. The goal is to secure the legal relationship of intended parents who conceive a child with third-party assistance from the moment of the child’s birth. A fertility lawyer may represent intended parents, gestational surrogates, or gamete donors in creating the necessary legal documents, such as Gestational Surrogacy Agreements, Egg/Sperm Donor Agreements, Embryo Donation Agreements, and Co-Parenting Agreements.
