Overview

The Act was a major legal recognition milestone for trans people in the UK. It followed a long legal arc from Corbett v Corbett, through the European Court of Human Rights judgment in Goodwin v United Kingdom, into a statutory process for gender recognition certificates. It also sits within later debates about reform, self-declaration, privacy, and equality.

Belgium Introduces Gender Self-Identification

Belgium's Legal Gender Recognition Act came into force, enabling individuals to change their legal gender through a statutory declaration before a civil registrar without medical intervention. The process involves a three-month waiting period and confirmation declaration. Minors aged 16-17 can apply with parental support and a non-diagnostic statement from a youth psychiatrist. In 2019, Belgium's Constitutional Court ruled the law must be expanded to include non-binary people.
