Enter into a PACS

pacte civil de solidarité (Pacs)

What is it

A civil contract between two adults who organise their life together, including how they share expenses. It is open to same-sex and different-sex couples, whatever their nationality.

Do I need it

Only if you want a registered legal status short of marriage. It is a choice, not a requirement, and it changes your tax and property position.

When

Whenever both partners are ready. There is no deadline, but the mairie sets the registration appointment.

Where · mixed

At the mairie of your shared address, or before a notaire. Some communes accept an online pre-application first.

Documents

Cost

Registering at a mairie is free. A notaire charges for registering a Pacs; the source page does not state the amount.

What happens next
  • Both partners attend in person and the registrar records the Pacs.
  • The Pacs takes effect between the partners from the date it is registered.
Renewal

A Pacs has no expiry date. Ending one (dissolution) is a separate procedure.
