Comoros · Overview

The legal system of Comoros

French civil-law codes layered over an Islamic personal-status law applied by qadi courts, within a federation in which each island retains substantial autonomy and its own governor. The applicable law depends on subject matter: personal status — marriage, divorce, inheritance — is governed by Islamic law before the qadis, while commercial and administrative matters follow the French codes. Island-level autonomy means administrative competence is genuinely divided, and identifying the responsible authority is a recurring practical problem.

Legal tradition

Comoros belongs to the mixed french civil law and islamic law tradition. French civil-law codes layered over an Islamic personal-status law applied by qadi courts, within a federation in which each island retains substantial autonomy and its own governor. The applicable law depends on subject matter: personal status — marriage, divorce, inheritance — is governed by Islamic law before the qadis, while commercial and administrative matters follow the French codes. Island-level autonomy means administrative competence is genuinely divided, and identifying the responsible authority is a recurring practical problem.

How power is divided

Federal. Grande Comore, Anjouan and Mohéli each have a governor and their own assembly with substantial autonomy over local administration, while the Union handles defence, currency, foreign affairs and nationality.
