When faced with a dispute, whether it is a neighborhood conflict, a divorce, or an unpaid invoice, a crucial question immediately arises: do you legally have to hire a lawyer? In French law, representation by a lawyer is sometimes a strict legal obligation, while in other situations, it remains optional, though highly recommended. Navigating the gears of the French justice system without knowing these rules can lead to your claim being dismissed or cause you to lose precious time. This comprehensive guide explains, area by area and court by court, when a lawyer is mandatory and how to act effectively to defend your rights.

To understand how justice works in France, one must distinguish between two concepts: the capacity to act in court (alone or assisted) and the obligation of representation.
Since the justice reform that entered into force on January 1, 2020, the rules of mandatory representation have been deeply harmonised. The general principle is set by Article 760 of the Code de procédure civile (French Code of Civil Procedure): before the Tribunal judiciaire (Judicial Court), parties are, unless otherwise provided, required to retain a lawyer. However, the legislature has provided numerous exceptions based either on the nature of the dispute or on the financial amount at stake.

In complex matters or when major financial and human interests are involved, the law imposes the presence of a lawyer. If you petition the court without a lawyer in these cases, your claim will be ruled inadmissible.
For the majority of civil disputes in daily life (contracts, debts, poorly executed works), the financial threshold is the deciding factor.
Family law touches upon the legal status of individuals, which explains the rigorous formalism imposed by law:

In the interest of simplification and access to justice, French law allows citizens to defend themselves alone in daily disputes or before specialized courts.
If your dispute concerns an amount less than or equal to €10,000, you can petition the court and defend yourself.
The Conseil de prud'hommes (labor tribunal) resolves disputes between employees and employers related to employment contracts (dismissal, unpaid wages, harassment).
For disputes between merchants or companies, a lawyer is in principle mandatory. However, the law provides a major exception: a lawyer is optional for all disputes involving an amount less than or equal to €10,000, as well as for insolvency proceedings (procédures collectives such as safeguard, receivership, or judicial liquidation) and disputes relating to register maintenance.
To challenge a decision made by the administration (town hall, prefecture, public school, etc.), a lawyer is generally optional in several frequent cases:
---
| Jurisdiction / Type of Dispute | Amount of the Dispute | Lawyer Mandatory? | Reference Texts |
| :--- | :--- | :--- | :--- |
| Tribunal Judiciaire (Civil) | $\le$ €10,000 | No (Optional) | Art. 761 of the CPC |
| Tribunal Judiciaire (Civil) | > €10,000 | Yes | Art. 760 of the CPC |
| Juge des Contentieux de la Protection (Residential leases, consumer credit) | Regardless of the amount | No (Optional) | Art. 761-1 of the CPC |
| Divorce (All forms) | Not applicable | Yes (One per spouse) | Art. 229-1 of the Civil Code |
| Conseil de Prud'hommes (1st instance) | Regardless of the amount | No (Optional) | Art. R. 1453-1 of the Labor Code |
| Tribunal de Commerce | > €10,000 | Yes | Art. 853 of the CPC |
| Tribunal de Commerce | $\le$ €10,000 | No (Optional) | Art. 853 of the CPC |
| Cour d'Appel (Civil matters) | Regardless of the amount | Yes (Except exceptions) | Art. 899 of the CPC |

If the law allows you to defend yourself and you choose this option for financial reasons, here are the steps to follow:
1. Attempt an amicable resolution (Mandatory): For any dispute under €5,000 or relating to a neighborhood conflict, you must legally attempt conciliation, mediation, or a procédure de procédure participative (participatory procedure) before petitioning the judge (Article 750-1 of the Code de procédure civile). This process is free of charge when done through a conciliateur de justice (justice conciliator).
2. Draft the petition: If conciliation fails, you must fill out the Cerfa (official French administrative form) adapted to your dispute (for example, Cerfa n° 16037\02 for a payment claim before the Tribunal judiciaire*).
3. Gather evidence: Assemble all your supporting documents (invoices, contracts, registered letters, photographs, written witness statements using the official Cerfa witness form).
4. File the claim: Send your petition along with the supporting documents to the clerk's office (greffe) of the competent court (usually the court of the defendant's place of residence, or the place of delivery of the good/performance of the service).
5. Notify the opponent: Depending on the case, the court clerk will summon the parties, or you must have a summons (assignation) delivered by a commissaire de justice (formerly known as a huissier de justice / bailiff), the average cost of which varies between €80 and €150.
6. Appear at the hearing: On the day of the hearing, you must present your arguments orally to the judge and answer their questions.
If a lawyer is mandatory or if you prefer the security of being represented, here is the typical path:
1. Choose your lawyer: You can consult the national directory of lawyers run by the CNB (Conseil National des Barreaux) or apply for legal aid (aide juridictionnelle) if you have a low income.
2. The first consultation: The lawyer analyzes your case. This first meeting is generally billed between €100 and €250 excl. tax (sometimes free if it leads to opening a case file).
3. *The fee agreement (convention de honoraires): This is a legal requirement. The lawyer must provide you with a written document detailing their billing method (hourly rate, generally between €150 and €350* excl. tax/hour, or a flat fee, possibly with a success fee).
4. Drafting legal documents: Your lawyer drafts the summons (assignation) to launch the lawsuit or the submissions (conclusions) to defend you, and transmits them to the court via the RPVA (the secure private virtual network for lawyers).
5. Representation: You generally do not need to attend procedural hearings. Your lawyer will plead your case during the trial hearing.

Yes, you are completely free to change lawyers at any point in the proceedings. However, you must pay the fees corresponding to the work already performed by the first lawyer before the new one can take over the file.
If your income is below a certain threshold (approximately €1,271 per month for a single person in 2024 for 100% coverage), you can benefit from Aide Juridictionnelle (Legal Aid). The State will then cover all or part of the lawyer's fees (who can be chosen by you or appointed by the court).
Yes. Unless they are appointed by the Bâtonnier (President of the Bar Association) as a court-appointed counsel, a lawyer has the right to refuse a case if they believe they do not have the required specialization, if there is a conflict of interest, or if they deem the case indefensible.
An avocat (lawyer) advises you, drafts your defense documents, and pleads for you in court. A commissaire de justice (formerly huissier / bailiff), on the other hand, officially delivers court summonses (assignations), drafts factual reports (constats) to serve as evidence, and legally enforces court decisions (such as asset seizures).
