Prevents a judge from prohibiting a parent from undergoing a gender reassignment when making a determination in a child custody case

This bill amends New York's domestic relations law to guide judges in child custody cases. It requires courts to ignore the parents' sex, sexual orientation, gender identity, or gender expression when deciding what is best for the child. Additionally, the law explicitly forbids judges from stopping a parent from undergoing gender reassignment as part of their custody determination. These changes apply immediately to ensure that custody decisions focus on the child's welfare without penalizing parents for their gender identity or medical transitions.
