Converting to Islam in France

In France, becoming Muslim requires no civil procedure: conversion is religious, pronounced with sincerity, and the civil registry does not record religion. The certificate of conversion issued by a mosque serves for religious marriage and pilgrimage. At the town hall, the first name can be changed by simple declaration since 2017, and the family name since the law of 21 February 2022.

Converting in France: no mandatory civil procedure

France knows no religious registration: nothing is to be declared, anywhere, to become Muslim. Conversion is a religious act between you and Allah (Sahih Muslim 121), valid immediately wherever you are. All the procedures described below are therefore optional: they serve your practice, not your validity.

The certificate of conversion

Issued by a mosque after pronouncing the testimony before the imam, it documents your Islam to Muslim institutions: religious marriage (the imam verifies the Islam of both spouses), pilgrimage (the Saudi authorities require it for the hajj or umra visa), or Muslim burial. Go to a mosque, ask to speak to the imam, the certificate is generally written and free. The page must I go to the mosque? details the process.

Changing first name or family name at the town hall

If you wish to take a Muslim first name, know that the first name is changed by simple declaration at the town hall since the law of 27 January 2017 (article 60 of the Civil Code): one form suffices, the civil registrar records it, without judicial procedure. The family name is changed since the law of 21 February 2022 (article 61-3 of the Civil Code) by the same simple route. None of these procedures has religious value: they are purely practical, to be done if you wish, never to be Muslim.

The page must I change my first name? recalls that it is not a condition.

Converting in France: your situation in practice

• Work: no mention of religion on the contract; adjustment requests (prayer times, fasting) are handled directly with the employer.
• Family: no legal announcement to make; the page non-Muslim family: what to do? treats the human announcement.
• Burial: for the confessional plots of public cemeteries, the mosque certificate or the regular practice of Islam is what town halls ask for.

Summary: pronounce the shahada (valid immediately), take your time for the rest. France requires nothing, Islam requires only a sincere heart.
