Dutch Civil Code
Article 1:19d Special cases (gender)
– 1. If the child’s gender is doubtful, then a birth certificate will be drawn up in which is recorded that the sex of the child could not be determined.
– 2. Within three months after birth or, when the child dies within this period, at the occasion of the report of death, a new birth certificate will be drawn up in which the child’s gender, if this has been established in the mean time, will be recorded by means of a submitted medical certificate, while the certificate mentioned in paragraph 1 will be deleted.
– 3. If no medical certificate has been submitted within the period mentioned in paragraph 2 or if such a medical certificate has been submitted within that period, but it indicates that it is still impossible to establish the child’s gender, then the new birth certificate will report that the sex of the child could not be determined.
