Is Cousin Marriage Legal in Indonesia After the 2026 Framework Overhaul?

Yes, cousin marriage is legal in Indonesia under specific conditions. The 1974 Marriage Law permits marriages between cousins, provided they meet general marriage requirements, such as age and consent. However, religious and regional customs may impose additional restrictions.


Key Regulations for Cousin Marriage in Indonesia

  • 1974 Marriage Law (Law No. 1/1974): Allows cousin marriages if neither party is already married, is of legal age (19+ for women, 22+ for men), and consents freely. Religious courts may impose further conditions based on local interpretations.
  • Religious and Customary Laws: Islamic courts in Indonesia often require a mahr (dowry) agreement and may scrutinize marriages between cousins for potential genetic risks, particularly in conservative regions like Aceh or West Java.
  • 2026 Compliance Shifts: The Ministry of Religious Affairs is drafting stricter guidelines for cousin marriages, mandating genetic counseling in high-risk areas to align with public health policies. Local governments (e.g., DKI Jakarta) may impose additional administrative hurdles.

Violations of these regulations can result in marriage annulment or penalties under regional ordinances. Consultation with a local religious or civil registrar is advised before proceeding.
