In 2014, the Open Society Foundations produced License to be Yourself, a report on progressive gender recognition laws and policies for trans people, and the activist strategies behind them. This brief is one of four complementary resources for activists. Each brief summarizes key arguments made by those opposing access to legal gender recognition. This resource focuses on minimum age restrictions that deny trans children and youth the right to legal gender recognition. It provides arguments that can be used by those advocating for rights-based gender recognition laws and policies. This brief also introduces issues relevant to children and young people with intersex variations. It recognizes that children with intersex variations often face a complex series of interactions with the medical system in order to obtain an initial sex classification.
