Handling a business dispute step by step

What counts as a business dispute?

A business dispute is any disagreement that arises between two parties in the course of commercial activity. For a small business owner in France, this covers a wide range of situations: a client who refuses to pay an invoice, a supplier who delivers defective goods, a partner who breaches the terms of a shareholder agreement, or a subcontractor who fails to complete work on time. Disputes can also involve leases for commercial premises, distribution contracts, or unfair competition from a former employee.

Not every disagreement becomes a formal legal matter. Many are resolved through a phone call or a corrected invoice. A dispute becomes serious when one party asserts a right and the other refuses to honour it, and when money, reputation, or the continuity of the business is at stake. Recognising early that you are in a genuine dispute, rather than a simple misunderstanding, helps you respond calmly and methodically instead of reacting emotionally.

It also matters whether the other party is a professional or a private individual (a consumer). The rules, the applicable court, and the tone of your approach can differ. A dispute between two companies is treated as a commercial matter, while a dispute with a consumer brings additional protections for the customer. Identifying the nature of the relationship at the outset shapes every step that follows.

Step 1: Review your contract and gather evidence

Before you contact the other side or take any action, go back to the paperwork. Read the contract carefully and identify the exact clauses that are relevant: payment terms, delivery deadlines, warranties, penalty clauses, and any provision describing how disputes should be handled. Many contracts contain a clause pointing to mediation or naming a specific competent court. Knowing what you signed prevents you from making claims the agreement does not support.

If there is no written contract, do not assume you have no rights. In France, commercial agreements can be proven by any means: emails, purchase orders, quotes (devis) that were accepted, invoices, delivery notes, and even a consistent pattern of past dealings. Gather everything in one place and organise it chronologically.

Build a clear evidence file. Useful items include the signed contract or accepted quote, all invoices and proof of payment or non-payment, correspondence showing what was promised and what went wrong, photographs of defective goods or incomplete work, and notes of any phone calls with dates. The stronger and more organised your file, the more persuasive you will be at every later stage, and the easier it becomes for a mediator or judge to understand your position quickly.

Step 2: Attempt an amicable resolution

The first genuine attempt to resolve a dispute should almost always be direct and informal. Contact the other party, explain the problem factually, and state clearly what you want: payment of an outstanding sum, repair of a defect, or completion of the work. Keep the tone professional. An aggressive first message often hardens positions and makes settlement harder.

Put your position in writing, even if you also speak by phone. An email creates a record and forces both sides to be precise. Describe the facts, refer to the relevant contract terms, and propose a concrete solution with a reasonable deadline. Sometimes offering a small compromise, such as a payment schedule or a partial discount, unlocks a resolution that would otherwise drag on for months.

An amicable phase serves two purposes. First, it may genuinely solve the problem at little cost. Second, if it fails, your good-faith attempt demonstrates to a future judge that you behaved reasonably. French courts increasingly expect parties to have tried to settle before litigating, and for many claims a prior attempt at amicable resolution is a legal requirement. Keep copies of everything you send and receive during this phase.

Step 3: Send a formal notice (mise en demeure)

When friendly exchanges have not worked, the next step is a formal notice known as a mise en demeure. This is a letter that officially demands the other party fulfil its obligation within a stated deadline. It marks a clear turning point: it signals that you are serious and prepared to escalate, and it produces legal effects, including starting the clock on late-payment interest in many cases.

A mise en demeure should be sent by registered post with acknowledgement of receipt (lettre recommandée avec accusé de réception) so you can prove it was received. The letter must clearly identify the parties, describe the obligation that has not been met, refer to the contract or invoices concerned, state precisely what you require, and give a firm but reasonable deadline to comply. It should also mention that you reserve the right to take legal action if the deadline passes.

Use the words 'mise en demeure' explicitly in the letter so there is no ambiguity about its nature. Keep the tone factual, not threatening. You can write it yourself, but for larger sums or complex situations it is worth having a professional review the wording, because errors can weaken its effect. Often the arrival of a formal registered letter is enough to prompt payment or a serious negotiation.

Step 4: Consider mediation or conciliation

If the formal notice does not resolve matters, consider an assisted amicable process before heading to court. France offers two main routes. Conciliation is free and handled by a conciliateur de justice, a volunteer who helps the parties find agreement, typically for smaller everyday disputes. Mediation involves a professional mediator, usually paid, and suits more complex commercial disagreements where the parties want a structured, confidential process.

Both approaches aim to reach a mutually acceptable solution rather than have a decision imposed. The advantages are significant: they are usually faster and far less expensive than litigation, they preserve business relationships that may still be valuable, and they keep the details private. An agreement reached this way can be recorded in writing and, if needed, given binding force through a judge's approval (homologation).

For many disputes below a certain value, attempting conciliation or mediation is not just advisable but legally required before a court will accept the case. Even where it is optional, judges look favourably on parties who tried. Approach these sessions prepared, with your evidence file organised and a clear idea of the minimum outcome you can accept, so that any agreement is realistic and durable.

Step 5: Understand your options for legal action

When amicable routes are exhausted, litigation becomes the remaining option. Before starting, weigh the cost, the time, and the likelihood of success against the amount at stake. A lawsuit over a small sum may cost more in fees and lost time than it recovers, while a substantial or principled dispute may justify the effort.

Several procedures exist depending on the situation. For a clear, undisputed debt, an injonction de payer (payment order) is a simplified, low-cost procedure where a judge can order payment without a full hearing. Where the matter is urgent, a référé allows you to obtain a fast provisional decision. For contested claims involving real disagreement over facts or interpretation, a full procedure on the merits is required, and legal representation is often advisable or mandatory above certain thresholds.

Be aware of time limits. Most commercial claims must be brought within a limited number of years (the prescription period), and once that window closes your right to sue is lost. This is another reason not to let a dispute drift. Also think ahead to enforcement: winning a judgment is only useful if the other party can actually pay. Checking that the debtor is solvent before investing in litigation can save disappointment later.

Which court handles business disputes in France?

The competent court depends on who the parties are. Disputes between two commercial businesses (commerçants or companies) are generally handled by the tribunal de commerce, a specialised court staffed by judges drawn from the business world. This includes disagreements over commercial contracts, unpaid invoices between professionals, and company matters.

When a dispute is between a professional and a private consumer, or involves a party who is not a trader, it usually falls to the ordinary civil court, the tribunal judiciaire. Certain matters have their own dedicated bodies: employment disputes go to the conseil de prud'hommes, and some rural or agricultural leases have specialised jurisdictions.

Geographic competence usually depends on where the defendant is based or where the contract was performed, though a valid clause in the contract may designate a specific court, particularly between businesses. If you are unsure which court applies, the mise en demeure and preliminary advice stage is the right moment to clarify it, because filing before the wrong court wastes time and money. The table below summarises the common routes at a glance.

Practical tips to reduce future disputes

Prevention is far cheaper than resolution. The single most effective habit is to put every agreement in writing with clear, specific terms. A signed contract or an accepted quote that spells out price, deliverables, deadlines, payment schedule, and what happens if something goes wrong removes most of the ambiguity that fuels conflict.

Invoice promptly and follow up consistently. Many payment disputes grow simply because reminders were sent late or not at all. Include your payment terms and late-payment penalties clearly on every invoice, and keep a system for tracking due dates. When a client starts paying slowly, address it early rather than letting the balance mount.

Keep good records throughout every relationship: confirm important verbal agreements by email, save delivery confirmations, and document any changes to the original scope. Consider adding a mediation clause to your standard contracts so that, if a problem arises, both sides already have a low-cost route to resolution. Finally, know your standard terms well and be consistent in applying them. A business that communicates clearly, documents diligently, and acts fairly is far less likely to find itself in a serious dispute, and far better positioned if one does occur.

FAQ

Do I have to try to settle before going to court? In many cases, yes. For disputes below a certain value, French law requires a prior attempt at amicable resolution, such as conciliation or mediation, before a court will accept the case. Even when it is not mandatory, judges view a good-faith attempt to settle favourably, so it is always worth documenting your efforts.

Is a mise en demeure legally required before suing? It is not always strictly required, but it is strongly recommended and produces useful legal effects, such as starting late-payment interest. Sending a formal notice by registered post shows you gave the other party a clear final chance to comply, which strengthens your position if the matter later reaches a court.

How long do I have to bring a business claim? Commercial claims are subject to a prescription period, meaning they must be brought within a limited number of years or the right to sue is lost. The exact period depends on the type of claim, so it is best to check early and not let a dispute drift, because delay can permanently close your options.

What if the other party has no money to pay? Winning a judgment is only useful if it can be enforced. Before investing time and money in litigation, it is wise to consider whether the other party is solvent. If a debtor genuinely cannot pay, a negotiated payment schedule reached amicably may recover more in practice than a court order that cannot be enforced.

Can I handle a business dispute without a lawyer? For simpler procedures, such as an injonction de payer or a small claim, you can often act without a lawyer. For contested claims or larger amounts, legal representation may be advisable or even mandatory above certain thresholds. Getting early advice helps you choose the right procedure and avoid costly mistakes.
