The birth certificate is one of the most important identity documents that contains information regarding a person's civil identity in society and expresses the existence of an individual or specific characteristics in society. The birth certificate (identity card, identity card, register) is an official document containing the name and surname, the name of the father and mother, the date and place of birth, the date and place of issuance of the document, the date of death, marriage and divorce, and the characteristics of the holder's children, and a copy of the general register of events. There are many lawsuits regarding the birth certificate, and one of its examples is the lawsuit to amend the birth certificate, which is under the jurisdiction of the peace court based on paragraph 11 of Article 12 of the Dispute Resolution Councils Law (1402), but the legislator has not specified the cases and examples of this lawsuit, and this will cause disagreement in the hearing of the courts of justice. The present study examines the issue of what are the most important examples of lawsuits to amend the birth certificate, using a descriptive-analytical method and using library tools and an applied approach, especially the judicial opinions of the courts of justice.
