Introduced by the law of 15 November 1999, the Pacte civil de solidarité (PACS - civil solidarity pact) has established itself as a key alternative to marriage for couples wishing to officialise their union in France. Governed by Articles 515-1 et seq. of the Code civil (French Civil Code), this form of partnership offers a flexible legal framework while conferring real rights and obligations on the partners. Whether you are a French citizen or a foreign resident in France, entering into a PACS requires a precise understanding of its conditions, its property and tax implications, as well as the procedures for its dissolution. This comprehensive guide will take you step-by-step through securing your life together.

For a PACS to be legally valid, the future partners must meet several strict substantive conditions set by the Code civil. Failure to do so may result in the contract being declared null and void.
Both partners must be of legal age (18 years old or over). Minors, even if emancipated, cannot enter into a PACS.
Article 515-2 of the Code civil prohibits a PACS between certain people in order to prevent incest. Thus, a PACS is strictly forbidden:
It is impossible to contract a PACS if one of the partners is already married or already bound by another PACS (in France or abroad, if the foreign union is recognised in France). Polygamy and multiple concurrent partnerships are prohibited.
France allows foreign national couples to enter into a PACS, provided that the couple establishes their joint primary residence on French territory. If the PACS is concluded abroad (at a French consulate or embassy), at least one of the two partners must be of French nationality.

Since the Law on the Modernisation of 21st Century Justice, the registration of a PACS is no longer carried out at the registry of the commercial or district court, but at the town hall or before a notary. Here is the step-by-step process to formalise your union.
You must choose between two options:
1. *The Mairie (Town Hall): The process is entirely free. You must apply to the civil status officer at the mairie* of your joint residence.
2. *The Notaire (Notary): Using a notaire incurs a fee (fixed regulated fees of approximately 102 € excluding tax, which is around 125 € including tax, plus additional administrative fees). The notaire* provides personalised legal advice and drafts a custom agreement.
For your application to be accepted, you must gather the following documents:
For foreign partners born abroad, additional documents are required:
Once the complete file has been submitted and validated by the mairie or the notaire, the partners must present themselves in person and together for the registration. The civil status officer or the notaire will verify your identities and register the PACS.
After registration, the information is automatically transmitted to the civil registry services. The mention of the PACS is added to the margin of each partner's birth certificate within an average of 3 to 4 weeks. For a foreign partner born abroad, the mention is recorded in a specific register held at the Service central d'état civil (Central Civil Status Service) in Nantes.

A PACS produces immediate effects upon registration. Contrary to popular belief, it imposes mutual duties close to those of marriage.
According to Article 515-4 of the Code civil, the partners commit to:
Partners are jointly and severally liable for debts contracted by either of them for the daily needs of the household.
> Practical Example No. 1: Marie and Thomas are in a PACS. Marie signs an electricity contract for their shared home for 120 € per month and takes out a consumer loan of 5,000 € to buy a personal car without Thomas's consent.
> * For the electricity (a daily household need), Thomas is jointly liable: if Marie does not pay, the provider can demand the 120 € from Thomas.
> * For the 5,000 € car loan (a clearly excessive expenditure not agreed to by both), Thomas is not jointly liable. The creditor can only pursue Marie.
By default, a PACS is subject to the regime of separation of property (séparation des patrimoines under Article 515-5 of the Code civil). Each partner remains the sole owner of the assets they acquired before and during the PACS, as well as their own income and salary.
However, partners can opt, in their initial or modified agreement, for the joint ownership regime (indivision). In this case, assets purchased together or separately after the registration of the PACS are deemed to belong to each partner on a 50/50 basis, regardless of each partner's actual financial contribution to the purchase.
On a tax level, a PACS offers exactly the same advantages as marriage:
Warning! Unlike a married spouse, a PACS partner is not a legal heir. In the absence of a will, the surviving partner inherits nothing, and the assets go entirely to the deceased's children or family. To remedy this, it is imperative to draft a will designating your partner as a beneficiary. Thanks to the PACS, this bequest will be completely exempt from inheritance tax.

A PACS differs from marriage in the simplicity of its dissolution, which does not require the intervention of a family court judge. Article 515-7 of the Code civil provides four grounds for dissolution.

Joint declaration to Served by a Marriage or Death
mairie/notary commissaire de justice (Automatic)
```
The partners decide together to end the PACS. They must send or deliver a joint declaration of dissolution (form CERFA No. 15789) to the mairie or the notaire who registered the initial PACS. The dissolution takes effect immediately on the date of registration.
One partner can decide alone to end the PACS. To do this, they must have their decision served to the other partner by a commissaire de justice (formerly known as a huissier de justice / bailiff).
The commissaire de justice delivers a copy of this notice to the mairie or the notaire who registered the PACS. The dissolution takes effect on the date the notice is registered by the competent authority.
The PACS ends automatically and by right if the partners marry (each other or someone else) or if one of them dies. No special formalities are required from the partners, as the civil status officer updates the records automatically.
> Practical Example No. 2: Julie and Marc dissolve their PACS after 5 years of living together. They had purchased an apartment in joint ownership (indivision) in equal shares (50/50), valued at 240,000 € at the time of dissolution, with 100,000 € left to pay on the mortgage.
> * The net value of the apartment to be shared is 140,000 € (240,000 - 100,000).
> Each partner is entitled to their share of the joint property, i.e., 70,000 € each. If Julie wishes to keep the apartment, she must buy out Marc's share (a soulte* payment of 70,000 €) and take over the mortgage in her sole name, subject to bank approval.

No. Unlike marriage, a PACS does not grant any right to the deceased partner's survivor's pension (pension de réversion), regardless of the number of years spent together or the presence of children. This is a major difference from marriage under French law.
Yes. Partners can modify their PACS agreement at any time and as many times as they wish. They must draft a modifying agreement (convention modificative) and have it registered with the mairie or the notaire who received the initial PACS.
Unilateral dissolution is almost immediate once the commissaire de justice has served the decision to the other partner and transmitted the deed to the mairie or the notaire. The cost of service by a commissaire de justice generally ranges from 150 € to 250 €.
For the Impôt sur la fortune immobilière (IFI - real estate wealth tax), PACS partners are subject to a joint declaration obligation. Their respective real estate assets are combined to assess the tax threshold, which is set at 1,300,000 €.
