ParisWhat 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

Frequently asked questions about real estate law
Why use a real estate lawyer
A real estate lawyer in Paris who specialises in this field understands the legal subtleties of property, in particular residential and commercial leases, co-ownership, construction and easements. Using a lawyer helps to secure your property projects effectively, through preventive support in property transactions such as purchases, sales or the drafting of leases. This approach avoids potential legal difficulties and anticipates the risks linked to contractual clauses, planning compliance and mandatory surveys.
In a landlord and tenant or property dispute, the lawyer puts in place a suitable strategy, such as a formal notice or a negotiation, to encourage an amicable settlement of the dispute. Where necessary, the lawyer represents you before the competent courts.
This expertise also allows the lawyer to defend your rights effectively in complex situations, such as a construction dispute, a latent defect or a neighbour dispute. The lawyer carefully ensures that legal time limits are met and assists you in gathering the evidence that is essential to your case.
Ultimately, consulting a real estate lawyer ensures that you act with rigour and peace of mind, protecting your interests in a field where mistakes can have serious consequences.
When should you consult a real estate lawyer?
There is no need to wait for a trial to consult a lawyer. Contrary to popular belief, a real estate lawyer is useful from the first signs of tension, or even when preparing a property transaction. It is particularly sensible to seek support as soon as the first unpaid rent appears, when faced with abusive conduct by a managing agent (syndic), or to challenge the minutes of a co-owners' general meeting. Preventive legal advice often prevents a delicate situation from getting worse.
It is also advisable to consult a lawyer whenever a legal question arises, whether for drafting or checking a lease, when in doubt about the lawfulness of a clause, when a building permit is refused or when faced with a complex administrative procedure. A lawyer's involvement secures your steps from the outset.
Finally, when a property dispute begins to emerge, whether a neighbour dispute, construction defects in the works or a disagreement with a developer, prompt assistance from a lawyer clarifies your rights and the various possible strategies before the dispute grows out of proportion.
Ultimately, the earlier a lawyer is consulted, the greater your chances of finding an amicable solution quickly. This proactive approach often leads to the resolution of the dispute without court proceedings or, at the very least, allows a solid file to be built in case of later proceedings.
How do you choose a good real estate lawyer in Paris?
To choose your real estate lawyer wisely, in particular in Paris, several essential criteria must be taken into account. First, favour a professional with genuine specialisation and solid experience in the different areas of real estate law, such as construction, co-ownership or leases. An explicit mention of the lawyer's specialisation, or a practice mainly focused on property, is generally a reliable sign of competence.
Also make sure the lawyer is locally based, in particular by checking registration with the Paris Bar if your case is connected with the capital. A locally established lawyer has a better grasp of the specific practices of the Paris courts and of regulatory particularities such as rent control or specific urban planning standards.
The firm's transparency and reputation are also essential. Find out how satisfied previous clients were and favour a professional who is clear about fees and able to explain the strategy precisely. Do not hesitate to ask for a detailed quote or a written fee agreement.
Finally, the first contact with the lawyer should be positive and reassuring. Use this first meeting to gauge the lawyer's listening skills, clarity of explanation and ability to build a relationship of trust. Smooth communication and a good understanding of your expectations are decisive factors.
In short, favour an experienced real estate lawyer, ideally based in Paris for a Paris dispute, with whom you feel genuine trust. A specialist lawyer will be better able to defend your interests effectively in complex property cases than a general practitioner.
In which cases do you need a real estate lawyer?
The situations requiring a real estate lawyer are numerous and varied. Common disputes include landlord and tenant problems such as unpaid rent, eviction proceedings, disputes over the security deposit, and disagreements between landlords and tenants about the condition of the property, works not carried out or termination of the lease.
In co-ownership matters, a lawyer can step in to challenge a decision of the general meeting, settle disputes over unjustified or unpaid charges, resolve neighbourhood disturbances or enforce the co-ownership regulations. The lawyer thus defends your interests effectively against the managing agent or the other co-owners.
In a property sale, the lawyer assists you if a latent defect is discovered, or if a promise to sell or a condition precedent is not complied with. The lawyer can bring actions to obtain either annulment of the sale or adequate compensation.
In construction, a lawyer's expertise is essential in the face of construction defects, non-compliance, delays or abandonment of the works. The lawyer helps you invoke the statutory warranties and establish the liability of the professionals concerned (contractors, architects).
For disputes over easements and property, such as disputes concerning a right of way, encroachments on a neighbouring plot, party walls or boundary determination, a lawyer's involvement allows you to assert your rights rigorously and effectively.
Finally, for all planning law questions, such as the refusal or challenge of a building permit, or compulsory purchase or pre-emption procedures in Paris, a lawyer experienced in planning law will be able to defend your interests as well as possible.
In short, whenever your situation concerns a property, whether in the context of a lease, a purchase, a construction or a co-ownership, consulting a lawyer helps you follow the right procedures and improves your chances of obtaining a favourable settlement.
How much does a real estate lawyer cost in Paris?
The fees of a real estate lawyer are freely determined by agreement with the client and vary according to several criteria, such as the complexity of the case, the time needed to handle it and the degree of urgency. However, here are some useful indications:
The first appointment at the firm is offered at €300 excl. VAT for a one-hour consultation. This appointment allows a precise review of your case and an assessment of the steps suited to your situation.
Beyond this first meeting, the lawyer will draw up a fee agreement setting out clearly the agreed method of billing, which may be hourly, fixed-fee or include a supplementary fee linked to the result obtained, depending on the particulars of the case.
Fees vary with the nature of the services: simple legal advice or the drafting of a deed will naturally cost less than complex litigation or lengthy court proceedings, such as an eviction or a dispute over construction works. Each firm applies rates according to its experience and local practice.
How do you prepare for the first consultation with a lawyer?
To get the most out of your first consultation with a real estate lawyer, it is essential to prepare well. We strongly recommend that you send us all relevant documents before the appointment, so that we can analyse your situation in advance and give you a suitable answer.
These documents include in particular the contracts concerned (lease, preliminary sale agreement, co-ownership regulations), exchanges of letters or formal notices, any court decisions or summonses, important communications (emails or text messages), and photographs or bailiff's reports in case of damage.
We also advise you to write a clear chronological summary of the important events in your case, specifying the key dates, the steps already taken and the replies or actions of the opposing party. This will make it easier to understand your case in detail.
Also prepare a precise list of your questions and objectives. Identify clearly the points on which you want clarification (risks incurred, estimated length of the proceedings, possible solutions) and your main objectives (recovering a sum of money, putting an end to a disturbance or cancelling a contract).
At the end of this first appointment, we will propose a defence strategy suited to your situation. We will also discuss practical aspects such as how the firm would act, the time required and the foreseeable fees.
My tenant has stopped paying rent: what can I do?
Unpaid rent is a complex and sensitive situation for a landlord-owner. If the tenant defaults on payment, it is essential to act quickly while strictly following the legal eviction procedure, which can generally last between 12 and 18 months. Here are the main steps to follow:
From the first missed payment, it is advisable to open an amicable dialogue with the tenant to understand the nature of the problem (temporary difficulty or ill will). An amicable arrangement, such as a payment schedule, can sometimes be enough to resolve an isolated delay.
If no prompt settlement follows, the next step is to have a court bailiff (commissaire de justice) serve a formal demand to pay invoking the termination clause of the lease. This document officially gives the tenant six weeks to pay the debt, including for furnished lettings (two months for leases already running on 29 July 2023 whose clause provides for that period). The demand is also notified to any guarantor and sent to the Commission for the Prevention of Evictions.
If the tenant still has not settled the situation when this period expires, it is then necessary to apply to the protection litigation judge to have the termination of the lease recorded and to seek the tenant's eviction. The writ of summons for urgent proceedings must be served on the tenant and sent to the prefecture at least six weeks before the hearing. The judge may order the eviction while possibly granting additional time to pay.
Finally, once the eviction decision has been obtained and the tenant still refuses to leave voluntarily, a court bailiff's involvement becomes indispensable to carry out the eviction. It is important to note that in France no eviction may be carried out during the winter eviction moratorium, from 1 November to 31 March, which can prolong the procedure.
A formal demand to pay invoking the termination clause opens a statutory period of six weeks for residential leases (two months for leases already running on 29 July 2023 whose clause provides for that period) and one month for commercial leases, after which termination takes effect automatically (Cass. civ. 3e, 8 December 2010, No. 09-16.939, published in the Bulletin). The tenant may request time to pay, which suspends the effects of the clause for as long as the tenant complies with them.
How long does an eviction procedure for unpaid rent take?
A formal demand to pay invoking the termination clause opens a statutory period of six weeks for residential leases (two months for leases already running on 29 July 2023 whose clause provides for that period) and one month for commercial leases, after which termination takes effect automatically (Cass. civ. 3e, 8 December 2010, No. 09-16.939, published in the Bulletin). The tenant may request time to pay, which suspends the effects of the clause for as long as the tenant complies with them.
What remedies do I have for a latent defect after buying property?
Discovering a latent defect after buying a property, such as a structural crack or a significant, non-apparent waterproofing defect, is a common concern for buyers. Fortunately, the law provides a latent defects warranty that allows remedies.
It is essential to act quickly once the defect is discovered: you have two years from that discovery to bring an action against the seller, with a maximum period of 20 years from the sale. The earlier you act, the better your rights will be preserved.
You have two main options: seek annulment of the sale by returning the property against reimbursement of the price paid (rescission action), or seek a proportionate reduction of the price while keeping the property (price-reduction action). If you show that the seller knew of the defect and did not inform you, you may also claim damages to cover the losses suffered.
To see this procedure through, it is often necessary to prove clearly that the defect existed and predated the sale, which generally involves a property expert assessment. An amicable expert assessment may suffice, but in case of disagreement with the seller, a court-appointed expert assessment ordered by the court will be more effective. A lawyer can assist you by applying to the court to appoint an expert and by ensuring that legal time limits are met.
The involvement of a lawyer who handles latent defects helps you to characterise the defect correctly, to choose the right procedure (annulment or compensation), to meet the legal time limits and to carry out the necessary steps. Finally, a lawyer can facilitate an amicable solution with the seller, who often prefers to negotiate an arrangement (price reduction or payment for the works) to avoid a trial.
The Court of Cassation holds that an urgent application for an expert assessment interrupts the short time limit of Article 1648 of the French Civil Code for the latent defects warranty (as then worded) (Cass. civ. 3e, 5 November 1997, No. 94-21.440, published in the Bulletin).
How do you assert a latent defect after buying a property?
The Court of Cassation holds that an urgent application for an expert assessment interrupts the short time limit of Article 1648 of the French Civil Code for the latent defects warranty (as then worded) (Cass. civ. 3e, 5 November 1997, No. 94-21.440, published in the Bulletin).
How do you resolve a co-ownership dispute or challenge a general meeting decision?
Life in a co-ownership can give rise to various disputes, such as neighbour conflicts, disagreements with the managing agent or challenges to decisions considered unfair. Several steps can resolve these disputes.
At first, dialogue is often the best solution. Attempting mediation with the managing agent or the co-owners concerned can prevent the conflict from worsening. Some co-ownerships have internal mediation committees, and there are also professional mediators who specialise in these matters.
If dialogue fails, it is possible to apply to the judicial court. A co-owner may, for example, challenge in court a general meeting decision considered prejudicial or irregular. Note that the time limits for acting are generally short (two months after notification of the minutes). A lawyer can then bring an action to annul the disputed decision. Likewise, in the case of unpaid charges, the managing agent or another co-owner may go to court to recover the sums due.
Where co-owners' rights are infringed, such as by repeated noise nuisance, works carried out without authorisation or abusive occupation of the common parts, it is possible to ask the court for an immediate end to the disturbance and, possibly, damages. A lawyer's assistance allows you to build your file effectively (witness statements, reports) and to act quickly, in particular by urgent application in an emergency.
For example, if a decision taken at the general meeting causes you harm (authorisation of unfavourable works, unjustified refusal of your own works), a lawyer will be able to identify the irregularities precisely in order to seek its annulment. Faced with a negligent or abusive managing agent (lack of financial transparency, late notices of meeting, inaction on problems), the lawyer can also establish its liability or even, as a last resort, seek its removal by the court.
In short, in a co-ownership it is essential to follow strictly the procedures laid down by the Law of 10 July 1965 governing co-ownership. A lawyer assists you in ensuring that these rules are respected and in effectively protecting your interests as a co-owner.
A challenge to a decision of the general meeting must be brought within two months of notification of the minutes (Article 42 of the Law of 10 July 1965). After this period the decision becomes final, which makes a prompt analysis essential.
What is the difference between a lawyer and a notary in real estate?
How do you challenge excessive co-ownership charges?
A challenge to a decision of the general meeting must be brought within two months of notification of the minutes (Article 42 of the Law of 10 July 1965). After this period the decision becomes final, which makes a prompt analysis essential.
What can I do if my building permit is refused in Paris?
A contentious challenge to a refusal of a building permit must be brought within two months of notification (Article R. 421-1 of the Code of Administrative Justice). An informal administrative appeal does not extend this period (Article L. 600-12-2 of the Planning Code, in force since 28 November 2025).
How do you revise the rent of a commercial lease in Paris?
A formal demand to pay invoking the termination clause opens a statutory period of six weeks for residential leases (two months for leases already running on 29 July 2023 whose clause provides for that period) and one month for commercial leases, after which termination takes effect automatically (Cass. civ. 3e, 8 December 2010, No. 09-16.939, published in the Bulletin). The tenant may request time to pay, which suspends the effects of the clause for as long as the tenant complies with them.
What are the time limits and conditions for returning the security deposit?
The security deposit must be returned to the tenant within a maximum of one month where the exit inventory of condition matches the entry inventory, or within two months where damage or discrepancies are recorded. Deductions from the security deposit are permitted only if clearly justified by quotes or invoices for the necessary repairs, or by service charges that are actually recoverable.
What is the notice period for a tenant of a furnished property in Paris?
In Paris, a tenant of a furnished property may terminate the lease at any time, subject to one month's notice, without having to give a reason. Notice must be given in writing, ideally by registered letter with acknowledgement of receipt or by bailiff's deed. The return of the keys officially marks the end of the lease.
How can a landlord give notice to a tenant (unfurnished or furnished property)?
A landlord may give notice to the tenant only on certain precise grounds: taking back the property to live in it, sale of the property or a legitimate and serious reason (for example, breaches by the tenant). The notice period is 6 months before the end of the lease for an unfurnished property and 3 months for a furnished property. The notice must include certain mandatory particulars and possibly be accompanied by specific supporting documents, in particular in cases of sale or repossession.
When is a rent supplement allowed?
A rent supplement is possible only for properties with particular and exceptional features that are not taken into account by the standard reference rent. This supplement can be challenged before the departmental conciliation commission or in court.
A formal demand to pay invoking the termination clause opens a statutory period of six weeks for residential leases (two months for leases already running on 29 July 2023 whose clause provides for that period) and one month for commercial leases, after which termination takes effect automatically (Cass. civ. 3e, 8 December 2010, No. 09-16.939, published in the Bulletin). The tenant may request time to pay, which suspends the effects of the clause for as long as the tenant complies with them.
What can you do if the Paris rent cap is exceeded?
If you find that the capped rent has been exceeded in Paris, you can report it online through your Mon Paris account. The lease and the rental advertisement must contain certain mandatory regulatory particulars concerning rent control. Their absence or non-compliance can lead to penalties. In such a situation, it is also advisable to consult a lawyer: a formal notice drafted by a professional is often enough to obtain satisfaction quickly.
A formal demand to pay invoking the termination clause opens a statutory period of six weeks for residential leases (two months for leases already running on 29 July 2023 whose clause provides for that period) and one month for commercial leases, after which termination takes effect automatically (Cass. civ. 3e, 8 December 2010, No. 09-16.939, published in the Bulletin). The tenant may request time to pay, which suspends the effects of the clause for as long as the tenant complies with them.
Can you let a property rated G in 2025?
Since 1 January 2025, it has been prohibited to let a property rated G because of the energy decency rules. This timetable also provides for the ban on properties rated F from 2028 and E from 2034. However, solutions exist, such as carrying out works, contractual adjustments or taking account of specific time limits linked to complex building sites.
What are the risks for a landlord letting a property considered "indecent"?
A landlord who lets a property that does not meet decency standards faces several risks, in particular an obligation to bring it into compliance, a possible reduction in rent and legal consequences that can go as far as court proceedings. These situations are becoming more frequent and are regularly reported in the media. Owners are therefore strongly advised to carry out a legal and technical audit before any letting or lease renewal.
Carrez Law: what are your rights if the stated area is wrong?
If the actual area of a property is more than 5% less than that stated in the sale deed, the buyer may request a proportionate reduction of the price. This action must be brought within one year of signing the sale deed.
