What a business lawyer in Lille does

- Business law
- Firm in Paris 17th
Lawyer at the Paris Bar — business law, contracts and commercial litigation.
Business law is played out on two fronts. First, the amicable stage: formal notice, negotiation, settlement protocol — most commercial disputes are resolved before any hearing when they are taken up early. Then the court: in Lille, the commercial court (tribunal de commerce) of Lille Métropole, 445 boulevard Gambetta, hears disputes between traders and those involving commercial companies (Article L. 721-3 of the French Commercial Code, the Code de commerce); disputes over the commercial lease regime fall mostly to the judicial court (tribunal judiciaire) of Lille, 13 avenue du Peuple Belge. No rule requires you to choose a local lawyer. Confidential first conversation on +33 6 46 60 58 22.

Contracts and unpaid invoices
Unpaid invoices, general terms of sale (CGV), termination of commercial relationships: the firm serves formal notice, negotiates and recovers debts — if need be through an urgent application for an interim payment (référé provision).
Commercial leases
Nine years, three-yearly notices to quit, renewal, eviction compensation: the commercial lease regime protects the business — its time limits are unforgiving (two years).
Company life
Shareholder disputes, removal of directors, share transfers, shareholder current accounts: the firm secures transactions and argues crises (Article 1843-4 of the French Civil Code, the Code civil).
Key points
Business litigation: your courts, one method
Address, contacts, appeals: practical points of reference.
- Disputes between traders and commercial companies: Lille Métropole commercial court, 445 boulevard Gambetta, 59200 Tourcoing — tel. 03 20 36 65 45 (Article L. 721-3).
- Commercial lease regime: Lille judicial court, 13 avenue du Peuple Belge, 59000 Lille — tel. 03 20 78 33 33, for most of the litigation.
- Appeals against judgments go to the court of appeal of Douai, 5 rue Merlin de Douai, 59500 Douai, within one month (Article 538 of the Code of Civil Procedure).
- In urgent cases, the president rules in urgent proceedings (référé): an interim payment where the debt is not seriously disputable, protective measures in case of a manifestly unlawful disturbance (Article 873 of the Code of Civil Procedure).
The firm, based on rue Margueritte in the 17th arrondissement of Paris, advises and defends company directors, traders and companies in Lille; where the law requires a lawyer with territorial representation rights, it arranges this with a colleague from the local jurisdiction. What matters: command of the subject and availability, from the first appointment through to the hearing.
Commercial leases
The commercial lease: the regime that protects the business
Nine years, renewal, compensated eviction: a mandatory public-policy regime with formidable time limits.
Position A
During the lease
- Minimum term of nine years, with the tenant entitled to give notice at each three-year break, six months in advance (Article L. 145-4).
- Unpaid rent: the termination clause takes effect only one month after a formal demand to pay that has gone unanswered (Article L. 145-41).
- Change of use, subletting, assignment of the lease: each operation follows its own conditions — and is prepared in writing.
Position B
At expiry
- The lease ends only by notice to quit (congé) given six months in advance by extrajudicial document (acte extrajudiciaire), or by a request for renewal (Article L. 145-9).
- Refusal of renewal: save for exceptions, the landlord owes eviction compensation — the market value of the business (Article L. 145-14).
- Note: all actions under the regime are subject to a two-year limitation period (Article L. 145-60) — a challenge to a notice to quit rarely tolerates delay.
Rule of thumb: date every notice to quit, every formal demand, every request — in a commercial lease, the two-year limitation period and the six-month time limits govern everything.
The firm acts in all business disputes:
- Commercial contracts
- Debt recovery
- Commercial leases
- Business sales
- Shareholder disputes
- Unfair competition
Companies
Companies and shareholders: securing matters, and settling them when necessary
Corporate life produces its crises: they are prevented in writing and resolved by law.
Shareholders stage
Shareholder disputes
Deadlocked decisions, abuse of majority rights, exclusion: the exit often runs through the transfer of the shareholder's rights — failing agreement on the price, an expert sets it (Article 1843-4 of the Civil Code).
Directors stage
Mandates and liability
Removal, remuneration, related-party agreements (conventions réglementées), liability for management fault: a director is protected by articles of association and minutes kept to the letter.
Transactions stage
Sales and warranties
Sale of a business (fonds de commerce) or of shares, warranty and indemnity agreement (garantie d'actif et de passif), due diligence: every clause carries weight — the drafting makes the transaction secure.
Nullities stage
Nullities: two years
Actions for nullity of the company or of corporate decisions are subject to a two-year limitation period (Article 1844-14 of the Civil Code, as worded following the 2025 reform).
The ordinary commercial limitation period is five years (Article L. 110-4 of the Commercial Code); for commercial leases, two years. Dating the starting point precisely is often half the case.
Timeline
From dispute to court: how it unfolds
The typical stages of a business case handled by the firm in Lille.
The dispute
Unpaid invoice, terminated contract, deadlocking shareholder: date the facts and gather contracts, emails and accounting documents from day one.
The consultation
Analysis of the contracts, time limits and evidence; quantification of the debt or the loss; choice of route — negotiation, urgent application, payment order or full proceedings on the merits.
Formal notice
A precise, quantified lawyer's letter resolves many commercial disputes; it fixes the positions and prepares the court stage if it proves necessary.
The writ of summons
Failing agreement, the case is brought before the Lille Métropole commercial court — by urgent application for an interim payment where the debt is not seriously disputable (Article 873 of the CPC).
The hearing and the decision
Pleadings, accounting documents, an expert's report if needed: each claim is quantified and proved — interest and costs included.
The appeal
The judgment may be appealed within one month before the court of appeal of Douai, 5 rue Merlin de Douai, 59500 Douai (Article 538 of the Code of Civil Procedure); provisional enforcement applies as of right.
Preparing your case
The documents to gather
The checklist that carries weight, in negotiation as before the judge.
- Contracts: general terms of sale, purchase orders, commercial lease, articles of association and shareholders' agreements.
- Invoices, account statements, payment schedules, acknowledgements of debt.
- Formal notices and replies, decisive emails, minutes of meetings.
- Minutes of general meetings and board meetings, management reports, annual accounts.
- Kbis extracts, deeds of transfer, warranty and indemnity agreements, pledges.
- Reports by a commissaire de justice (court bailiff), amicable expert reports, accounting correspondence.

Frequently asked questions
Your questions: business law
Can a Paris lawyer handle my business case in Lille?
Yes. Advice, contract drafting and negotiation are not limited by bar boundaries; the firm handles its Lille cases from start to finish.
Before the commercial court as before the Lille judicial court, where the law requires representation by a lawyer with territorial representation rights, the firm arranges this with a colleague from the local jurisdiction: you keep your lawyer for strategy, drafting and the hearing.
The firm, based on rue Margueritte in the 17th arrondissement of Paris, acts for company directors, traders and companies in Lille.
A customer is not paying its invoices: how can I recover the debt?
In order: a reminder, a formal notice from a lawyer, then the route suited to the case — a payment order (injonction de payer), an urgent application for an interim payment where the debt is not seriously disputable (Article 873 of the Code of Civil Procedure), or a writ of summons on the merits.
Commercial obligations are subject to a five-year limitation period (Article L. 110-4 of the Commercial Code): the older the debt, the weaker it becomes.
The firm quantifies the debt, interest and costs, and chooses the procedure that yields results fastest.
Commercial lease: what are the pitfalls of the statutory regime?
The time limits. The lease runs for a minimum of nine years (Article L. 145-4); it ends only by notice to quit given six months in advance by extrajudicial document or by a request for renewal (Article L. 145-9).
All actions under the regime are subject to a two-year limitation period (Article L. 145-60): a challengeable notice to quit, a claim for eviction compensation or an uncapping of the rent are never to be examined "later".
The firm reviews the lease, calculates the deadlines and secures notices to quit and renewals — for landlords and commercial tenants alike.
My landlord refuses to renew my commercial lease: what are my rights?
Save for exceptions provided by law, refusal of renewal gives rise to eviction compensation: it makes good the tenant's loss and includes in particular the market value of the business (Article L. 145-14 of the Commercial Code).
The action is subject to a two-year limitation period: the date of the notice to quit governs the whole timetable.
The firm quantifies the compensation — the business, removal and relocation costs — and negotiates or argues it.
Which court hears my business dispute in Lille?
Disputes between traders and disputes involving commercial companies: the Lille Métropole commercial court, 445 boulevard Gambetta, 59200 Tourcoing — telephone 03 20 36 65 45 (Article L. 721-3 of the Commercial Code).
Disputes over the commercial lease regime fall mostly to the Lille judicial court, 13 avenue du Peuple Belge, 59000 Lille — telephone 03 20 78 33 33.
Appeals go to the court of appeal of Douai, 5 rue Merlin de Douai, 59500 Douai, within one month.
Shareholder dispute: how can I get out of it?
Through negotiation first: share transfer, buy-back, settlement protocol — most crises are resolved by an agreement with figures attached.
Failing agreement on the price of the shares, an expert sets it, appointed by the parties or by the president of the court (Article 1843-4 of the Civil Code).
The firm also argues cases of abuse of majority rights, removals and, when the situation requires it, dissolution — protecting the business first.
A general meeting decision seems irregular to me: can I challenge it?
Yes, under strict conditions: since the 2025 reform, actions for nullity of the company or of corporate decisions are subject to a two-year limitation period (Article 1844-14 of the Civil Code).
Irregularity is assessed against the law and the articles of association: notice of the meeting, quorum, majority, abuse.
The firm analyses the minutes and articles of association, and weighs nullity, liability and negotiation against each other.
Sudden termination of an established commercial relationship: what remedies are there?
Terminating an established commercial relationship without sufficient written notice engages the liability of the party responsible; the loss is calculated on the margin lost during the notice period that should have been granted.
The evidence has to be built: length of the relationship, turnover, economic dependence, written exchanges.
The firm assesses the notice period owed, quantifies the loss and negotiates or issues proceedings — often both.
What can the firm do in an emergency?
Apply to the president in urgent proceedings: an interim payment where the debt is not seriously disputable, protective measures or restoration to prevent imminent damage or to put an end to a manifestly unlawful disturbance (Article 873 of the Code of Civil Procedure).
A termination clause in a commercial lease takes effect one month after a formal demand to pay (Article L. 145-41): a quick response makes the difference.
In an emergency, call directly: the first consultation is used to secure your position, then to build the case.
What are the fees for a business case in Lille?
Fees are set out in a written agreement, in accordance with Article 10 of the Law of 31 December 1971: before committing, the client knows what the assignment covers and what it costs.
The firm favours a fixed fee per stage: consultation and strategy, formal notice, proceedings on the merits or urgent application, appeal — and a success fee in debt recovery where appropriate.

What our clients say
Best real estate law and business law lawyer in Paris. A humane and attentive lawyer, with a wonderful team. Thank you, Maître KOHEN
Translated from French
Thank you to Maître KOHEN for his analyses of recent case law on fraudulent non-disclosure in property sales. It reassures me about an action for annulment that I am considering after buying a house affected by serious defects intentionally concealed by the seller and not reported by the estate agent; also defects (rising damp) characterised by spreading through-cracks and damp stains, not reported by the estate agent… Worse, defects concealed by the latter or at his instigation, under a coat of paint and by polystyrene tiles glued to the ceiling of a bedroom. And the said estate agent drafted the preliminary contract, which of course contains no information about any of these defects. Just to add that, being 77 years old and suffering from cognitive impairment, I am certain that the estate agent thought I would not be able to discover the deception and above all to establish the fraudulent intent, still less to bring legal proceedings given the complexity and length of the procedure... That is why I am opting for the criminal route, insofar as the intentional concealment of the defects by the seller and then by the estate agent amounts to the fraudulent manoeuvres of art. 313-1 of

As a young student living in an apartment, my landlord tried to make me leave my accommodation even though he had sent me no termination notice. I therefore contacted Mr. Reda Kohen to help me as I couldn’t handle the situation alone.
