Full official record
Law 4491/2017 (Government Gazette A 152/13.10.2017) lets a person from age 15 correct the registered sex. From 15, that path needs parental consent and a positive opinion from an interdisciplinary committee of a child psychiatrist, psychiatrist, endocrinologist, pediatric surgeon, psychologist, social worker, and a pediatrician as chair. That statute is a legal-and-medical pathway, not a DSD correction rule.
