Unseizability of a sole trader's main residence: what is left for the creditor to seize

A sole trader ceases to pay its debts. The lender holds an unsecured business exposure, URSSAF (the social security collection body) claims two years of contributions, and a supplier holds an enforceable title. They all look at the same asset: the house. Since the Macron Law of 2015 and then the single status that came into force on 15 May 2022, the reflex answer is that this property is out of reach. That answer is wrong in a significant number of cases, and the difference turns on points that can be checked before credit is even granted: the date on which the claim arose, whether it is professional or personal in nature, the existence of a valid waiver, and the actual use of the property. From the standpoint of the institutional creditor and the lender, this analysis sets out the real scope of the unseizability (insaisissabilité) of a sole trader's main residence, the weaknesses that can be exploited and the procedural timetable within which they must be raised.

Two overlapping regimes on the same property

The protection of a sole trader's main residence does not rest on a single provision but on two mechanisms of different origin and logic, which are cumulative without being the same. Treating them as a single block is the creditor's first analytical error.

Unseizability by operation of law under Article L. 526-1 of the French Commercial Code

Originating in Law No. 2003-721 of 1 August 2003 in the form of an optional notarised declaration of unseizability (DNI), the protection became automatic with Article 206 of Law No. 2015-990 of 6 August 2015 for growth, activity and equal economic opportunities. Article L. 526-1 of the French Commercial Code now provides, by way of derogation from Articles 2284 and 2285 of the French Civil Code, that the rights of an individual carrying on an independent professional activity in the property in which his or her main residence is located are unseizable by operation of law by creditors whose rights arise in connection with the professional activity.

Three cumulative conditions therefore define the scope of the provision: an individual carrying on an independent activity, a property that is the main residence, and a claim arising in connection with the professional activity. Each of them can be challenged before the enforcement judge (juge de l'exécution). The second paragraph provides that where the main residence is used in part for professional purposes, only the portion not assigned to that use is unseizable by operation of law, without any need for a descriptive statement of division. Other built or unbuilt land not assigned to professional use is protected only by a notarised declaration published with the land registry (service de la publicité foncière), under the conditions of Article L. 526-2.

Separation of estates under the single status

Law No. 2022-172 of 14 February 2022 in favour of independent professional activity created, in Article L. 526-22 of the French Commercial Code, a division of assets by operation of law. The sole trader holds a professional estate, made up of the assets, rights, obligations and security interests useful to the activity, and a personal estate made up of everything not included in the first. Decree No. 2022-725 of 28 April 2022 details the notion of useful assets. The security of professional creditors is in principle limited to the professional estate; that of personal creditors to the personal estate, extended to the professional estate within the limit of the profit of the last closed financial year where the personal estate is insufficient.

The consequence for the lender is direct. Under the regime of the professional estate under the single status, the main residence by its nature forms part of the personal estate, except for the portion assigned to the activity. It therefore escapes the professional creditor's security not because it is a main residence, but because it is not assigned to the activity. The two regimes lead to the same apparent result, but the ways around them are not the same: waiver of unseizability falls under Article L. 526-3, and waiver of the separation of estates under Article L. 526-25. Confusing them guarantees that the enforcement will fail.

The real scope of the protection: weaknesses that can be exploited

Unseizability is an exceptional privilege, strictly construed. A methodical creditor systematically checks the following points before giving up on pursuing the property.

The date on which the claim arose governs everything. Unseizability by operation of law can be set up only against creditors whose rights arose after the entry into force of the Law of 6 August 2015. The separation of estates, for its part, takes effect only in respect of claims arising after 15 May 2022, in accordance with the transitional provisions of the Law of 14 February 2022. A business exposure granted before that date and renewed without novation remains secured on all of the sole trader's assets, subject only to Article L. 526-1. In current default cases, which frequently concern commitments entered into before 2022, this prior date is the first lever to examine.

The characterisation of the claim comes next. Article L. 526-1 protects only against professional creditors. Personal creditors retain an intact right of security over the main residence: the lender that financed the acquisition, the co-ownership association (syndicat des copropriétaires) for the building's charges, maintenance creditors, and the public accountant for income tax. This last point is decisive. Article L. 273 B of the French Tax Procedure Code allows the public accountant to pursue recovery against all of the sole trader's assets of the income tax and social levies owed by him or her, as well as of the property tax on real property useful to the activity. The Treasury thus has a pool of assets that the private creditor does not have, which changes the expectations as to ranking in a recovery plan.

Main residence status must be effective on the day of the seizure. Unseizability by operation of law follows use, not ownership. A sole trader who leaves the premises, lets the property or settles elsewhere on a lasting basis loses the benefit of the provision for that property, in the absence of a notarised declaration covering a property that has become a secondary one. Checking use, by a bailiff's report or by cross-checking declared addresses, is part of the preparatory work before the payment order valid as a property seizure (commandement de payer valant saisie).

The fate of the sale price calls for the same vigilance. Article L. 526-3 carries unseizability over to the sale price, but on condition that the sums are reinvested in the acquisition of a new main residence within one year. Once that period has passed without reinvestment, the balance returns to the common security. A creditor who identifies a sale must therefore schedule monitoring of the reinvestment and secure the proceeds by a protective measure on the notary's deposit account or on the claim for the price. The conditions and effects of that measure are set out in our article on protective seizure to secure a claim.

Lastly, mixed use splits the protection. The professional premises fitted out in the house, the workshop, the office and the adjoining warehouse form part of the professional estate and remain seizable by the professional creditor. The debate then shifts to the make-up and valuation of the assigned portion, a point that is prepared by expert appraisal and not by late arguments in defence.

Mapping the professional creditor's residual security

Setting aside the main residence does not mean giving up on recovery. The sole trader's professional estate remains seizable without restriction by the creditor whose claim arose in connection with the activity. It includes in particular the business (fonds de commerce) or craft business, the non-commercial clientele, the leasehold right, goods and stock, equipment and tooling, trade receivables, bank accounts dedicated to the activity, premises used for the business and shareholdings held for the purposes of the activity.

Three assets deserve particular attention in a recovery strategy. First, trade receivables, which can be seized by attachment of debts (saisie-attribution), offer a quick return and escape the debate on assignment where invoicing is issued in the name of the sole proprietorship. Second, the commercial leasehold right, the realisation of which requires anticipating the assignment clauses and the landlord's attitude. Finally, vehicles and equipment, often financed by leasing and therefore outside the security, which requires the contracts to be checked before any measure is taken.

The shift of the professional estate to a company is the most significant risk of leakage. Article L. 526-27 of the French Commercial Code authorises the universal transfer of the professional estate, in particular by contribution to a company, without liquidation. Creditors prior to the publicity of the transfer have a right of opposition within the period set by regulation. Failure to exercise that right within the period is final. A lender that does not monitor the legal notices relating to its sole trader debtor accepts, in effect, that its pool of assets may be transferred.

Waiver: two separate instruments, two sets of formalities

This is where most of the prevention is decided. Protection of the main residence is not a matter of absolute public policy: it can be set aside by waiver. But the instrument must be the right one.

Waiver of unseizability falls under Article L. 526-3 of the French Commercial Code. It may be made for the benefit of one or more named creditors, for all or part of the protected assets, and requires compliance with notarial formalities as well as publication with the land registry. A waiver stipulated in a private agreement, in a loan offer or in general conditions has no effect. The waiver may be revoked at any time, but the revocation applies only to creditors whose rights arise after its publication: the original beneficiary keeps its benefit for the claim covered.

Waiver of the separation of estates follows an entirely different regime, laid down in Article L. 526-25. It requires a written request from the creditor, relates to a specific commitment whose term and amount, determined or determinable, must be stated, and observes a cooling-off period of seven clear days from receipt of the request. That period may be reduced to three clear days if the sole trader adds a handwritten statement attesting to the waiver of the period. Decree No. 2022-709 of 26 April 2022 sets the model form of the instrument. Failure to observe the formalities is sanctioned by nullity of the waiver.

Three pitfalls should be pointed out to commitments departments.

• Waiver of the separation of estates is specific to a commitment: it covers neither earlier exposures, nor new facilities, nor, on a cautious reading, a rescheduling that would change the amount or the term. Every amendment calls for the coverage to be reviewed.
• Waiver of the separation of estates is not a waiver of the unseizability under Article L. 526-1, and vice versa. A lender that wants to be able to seize the main residence must obtain both instruments, in their respective forms.
• Taking a contractual mortgage over the main residence, or enforcing the special statutory mortgage of the lender of funds under Article 2402 of the French Civil Code, arising from Ordinance No. 2021-1192 of 15 September 2021, does not remove the need to analyse the characterisation of the secured claim. It is better to back the security interest in the property with an express published waiver than to rely on an implied waiver whose scope remains debated.

Fraud and serious breach: judicial recovery of the security

The legislature has attached a robust sanction to the separation of estates. Article L. 526-24 of the French Commercial Code provides that in the event of fraud or serious breach of the rules on the assignment of the professional estate or of the statutory accounting obligations, the sole trader is liable for debts arising in connection with the activity on all of his or her movable and immovable property. The text also refers to Article L. 273 B of the French Tax Procedure Code for the tax authority and to Article L. 133-4-7 of the French Social Security Code for social recovery bodies, in the case of fraudulent practices or serious and repeated failure to meet filing and payment obligations.

The conduct that can be relied on is concrete and can be documented from accounting and banking records: a complete absence of accounts or manifestly untrue accounts, permanent mixing of flows between the personal and business accounts, payment of private expenses from the business account, transfer of business assets to the personal sphere without consideration on the eve of cessation of payments, and overstatement of the professional estate declared to the lender and later contradicted by the accounts. A creditor considering this route must build its case before insolvency proceedings are opened, while it still has access to information under Article 145 of the French Code of Civil Procedure.

In parallel, the Pauline action (action paulienne) under Article 1341-2 of the French Civil Code remains fully useful against acts of impoverishment carried out in fraud of the creditor's rights: a gift of the bare ownership to the children, a contribution of the property to a civil property company (société civile immobilière) on unbalanced terms, or a fiducie set up to act as a screen. Case law has long accepted that the notarised declaration of unseizability, like any legal act, cannot be enforced against a creditor where it results from a fraud on its rights. The burden of proof lies on the creditor, which makes it necessary to document the debtor's knowledge of the state of its liabilities at the date of the act. On the bringing of this action where the debtor is subject to insolvency proceedings, see our analysis of the Pauline action in insolvency proceedings.

Insolvency proceedings: who can still act against the main residence

Since Book VI of the French Commercial Code was adapted to the single status, insolvency proceedings opened against a sole trader relate, in principle, only to his or her professional estate. The personal estate, and therefore the main residence, remains outside the scope of the proceedings, except for a merger of estates ordered in the case of commingling or in the statutory cases of fraud.

This produces an interplay that lenders underestimate. The stay of individual enforcement under Article L. 622-21 of the French Commercial Code does not neutralise creditors against whom unseizability or the separation of estates cannot be invoked. The liquidator, who represents the collective interest of the creditors, has no standing to take hold of an asset that the law removes from their security. The creditor whose claim predates 2015, the personal creditor and the creditor benefiting from a validly published waiver retain the right to begin or continue a property seizure against the sole trader over the main residence, using the ordinary enforcement procedures.

This right nevertheless presupposes that one's rights have been preserved. Filing the claim within the two-month period of Article L. 622-24 of the French Commercial Code remains required for the claim falling within the professional estate. And the coexistence of insolvency proceedings over the professional estate with a property seizure over the personal estate calls for close coordination of timetables: the forced sale of the property, the distribution of the price and the settlement of registered security interests follow their own chronology, independent of the plan.

Property seizure: the timetable in which the challenge is won

The debate on unseizability does not take place in the abstract but within a strictly sequenced procedural framework. The procedure begins with service of a payment order valid as a property seizure, published with the land registry under the conditions of Articles R. 321-1 et seq. of the French Code of Civil Enforcement Procedures, and continues with the summoning of the debtor to the guidance hearing (audience d'orientation) before the enforcement judge. The course of this procedure, from the payment order to the sale, is dealt with separately in our article on the timetable of a property seizure, step by step.

Article R. 311-5 of the same Code requires all arguments to be raised together: on pain of inadmissibility raised of the court's own motion, no challenge or incidental application may, save exceptions, be made after the guidance hearing. In other words, a debtor who does not invoke the unseizability of his or her property before that hearing is time-barred. For the creditor, this rule has a direct strategic consequence: the quality of the analysis carried out before the payment order determines the strength of its position, since the ground of the debate will be fixed at a single hearing.

Two precautions are needed before proceedings are begun. First, a documentary audit of the land registry, which reveals notarised declarations of unseizability, published waivers and any revocations of them. Second, a reasoned characterisation of the claim, professional or personal, with the documents of origin of the commitment: an enforceable title does not remove the need to show that unseizability cannot be invoked.

What the lender should require when granting credit

Protection of the main residence is now the rule. A creditor that wants to be free of it must organise this contractually, at the time when it still has bargaining power, that is, before funds are disbursed. The chain of control comes down to a few steps whose absence cannot be made good afterwards.

• Precise identification of the debtor's status and of the date on which each commitment arose, exposure by exposure, to determine the applicable regime.
• Obtaining, where the property makes up a decisive part of the financial standing, a waiver of unseizability in notarised form published with the land registry and, separately, a waiver of the separation of estates in the format of the Decree of 26 April 2022, with demonstrable compliance with the cooling-off period.
• Registration of a security interest over the property rather than reliance on a declaratory personal commitment, and review of the coverage at each amendment changing the amount or the term.
• Seeking guarantees located outside the protected perimeter: a guarantee from a solvent third party, a pledge of a life insurance contract, a fiducie used as security over unassigned personal assets.
• Monitoring of legal notices throughout the life of the credit, in particular of any universal transfer of the professional estate, so as not to let the period for opposition expire.

Conclusion

The unseizability of a sole trader's main residence is not a shield; it is an exceptional regime of variable geometry. It gives way before the prior date of the claim, before the personal characterisation of the debt, before the lack of actual assignment of the property, before failure to reinvest the sale price, before fraud and before a validly granted waiver. A creditor that concludes too quickly that seizure is impossible gives up an asset that is often decisive; one that begins a seizure without a prior audit of the land registry and without a reasoned characterisation of its claim risks failure at the guidance hearing, with the costs that follow.

Our position is that the subject is one for the granting of credit, not for litigation. Before any new facility to a sole trader, have a written map prepared of the security actually available, exposure by exposure, distinguishing what belongs to the professional estate under the single status from what belongs to the personal estate, and make disbursement conditional on production of the waivers in their respective statutory forms. A waiver obtained when the funds are released costs one notarial deed; the same protection sought two years later, in a context of default, can no longer be obtained.

Frequently asked questions

Is a sole trader's main residence completely unseizable? No. Article L. 526-1 of the French Commercial Code makes the property unseizable only against creditors whose rights arise in connection with the professional activity, and only for claims arising after the entry into force of Law No. 2015-990 of 6 August 2015. Personal creditors, including the lender that financed the acquisition, the co-ownership association and the public accountant in respect of income tax, retain a full right of security. The portion of the property assigned to professional use also remains seizable.

Does the separation of estates under the single status protect debts prior to 15 May 2022? No. The mechanism of Article L. 526-22 of the French Commercial Code, arising from Law No. 2022-172 of 14 February 2022, applies only to claims arising after its entry into force, set at 15 May 2022. A business exposure granted before that date remains secured on all of the sole trader's assets, subject only to the unseizability of the main residence. This distinction remains decisive in current default cases.

Is a clause waiving unseizability inserted in a loan agreement valid? No, it is ineffective. The waiver provided for in Article L. 526-3 of the French Commercial Code requires an instrument drawn up in notarial form and published with the land registry, for the benefit of one or more named creditors. A stipulation in a loan offer, a private agreement or general conditions has no effect on whether unseizability can be invoked.

Is it necessary to obtain both a waiver of unseizability and a waiver of the separation of estates? Yes, they are two separate instruments subject to different formalities. The first falls under Article L. 526-3 and requires notarial form with land registry publication. The second falls under Article L. 526-25, requires a written request from the creditor, relates to a commitment determined in amount and term, observes a cooling-off period of seven clear days, reducible to three days with a handwritten statement, and follows the model of Decree No. 2022-709 of 26 April 2022.

Can the liquidator sell the main residence of a sole trader in compulsory liquidation? In principle, no. The insolvency proceedings relate to the professional estate and the liquidator, who represents the collective interest of the creditors, has no standing to take hold of an asset removed from their security. However, creditors against whom unseizability cannot be invoked, in particular personal creditors and those benefiting from a published waiver, retain the right to begin an individual property seizure over that property despite the stay of proceedings.

What becomes of unseizability if the sole trader sells his or her main residence? Article L. 526-3 of the French Commercial Code carries unseizability over to the sale price, on condition that the sums are reinvested in the acquisition of a new main residence within one year. Failing reinvestment within that period, the price returns to the creditors' security. The creditor must therefore monitor the sale and secure the funds by a suitable protective measure.

At what point must unseizability be raised in property seizure proceedings? Before the guidance hearing. Article R. 311-5 of the French Code of Civil Enforcement Procedures requires, on pain of inadmissibility raised of the court's own motion, that challenges and incidental applications be made before that hearing. For the pursuing creditor, this means that the whole analysis of whether unseizability can be invoked must be carried out and documented before the payment order valid as a seizure is served.
