Enforcing an asset and liability warranty: notification, expiry deadlines and litigation

A buyer who discovers, six months after signing, an URSSAF (French social security contributions body) reassessment covering periods before the sale, or an employment tribunal dispute whose triggering event dates back to the former management, then appreciates the full importance of the asset and liability warranty (garantie d'actif-passif) negotiated in the protocol. It is still necessary to know how to call on it. Enforcing an asset and liability warranty is subject to strict formalities and to expiry deadlines (délais de forclusion), failure to meet which deprives the buyer of any remedy, whatever the reality of the loss. This analysis is aimed at buyers, investment funds and acquirers who need to turn a contractual clause into actual compensation, anticipating the seller's challenge and the workings of the escrow.

A reminder: what an asset and liability warranty actually guarantees

The asset and liability warranty (GAP) is a contractual provision inserted in the agreement for the transfer of shares or company interests, by which the seller undertakes to indemnify the buyer for the consequences of a liability whose origin precedes the sale but which comes to light afterwards, or for an overstatement of assets. It rests on the binding force of contracts enshrined in Article 1103 of the French Civil Code, under which legally formed contracts take the place of law for those who have made them. The risks of a sale concluded without such a provision, and the remedies under general law then available to the buyer, are analysed in our article on the sale of company shares without a liability warranty.

Two rationales must be distinguished, which practice often confuses. The liability warranty in the strict sense (stricto sensu) covers the emergence of a new liability not provisioned in the reference accounts (tax reassessment, social security debt, employment tribunal award, commercial dispute). The asset warranty, or value restoration warranty, covers the disappearance or overvaluation of an asset (irrecoverable trade receivable, written-down inventory, overvalued fixed asset). A well-drafted clause deals with both and specifies whether the indemnity is paid to the target company (restoration warranty) or directly to the buyer (value warranty), a distinction with major tax and practical consequences.

This distinction is not theoretical. Where the indemnity is paid to the company, it restores net assets and benefits the buyer indirectly, as a shareholder from then on. Where it is paid to the buyer, it reduces the acquisition price. The protocol must settle this point, failing which liability warranty litigation shifts to the question of who is entitled to the compensation.

The triggering event and its date of origin

The core of the mechanism lies in the notion of a triggering event preceding the sale. The GAP covers only liabilities whose legal cause or origin lies before the reference date (often the accounts cut-off date or the completion date). A tax reassessment notified after the sale but relating to earlier financial years falls within the scope of the warranty. Conversely, a debt arising from a management decision of the buyer after the transfer of control is excluded.

The characterisation of the date of origin is the first ground of challenge. For an employment tribunal dispute, the origin may be the employer's breach (earlier) rather than the referral to the employment tribunal (conseil de prud'hommes) (later). For an URSSAF reassessment, it is the period audited that counts, not the date on which recovery proceedings were commenced. A well-advised buyer requires wording that expressly refers to the triggering event, its cause or its origin, a formulation more protective than a mere reference to the date on which the debt arose.

The GAP claim notice: formalities on pain of forfeiture

The GAP claim notice, also called notification or call under the warranty, is the instrument by which the buyer informs the seller of the occurrence of an event capable of triggering the warranty. It is the most contentious stage, because the seller systematically looks in it for the formal defect that will defeat the claim.

Mandatory content of the notification

GAP agreements regulate the content of the notice precisely. In general, the notification must include:

• a precise description of the event or of the liability that has come to light
• the basis of the claim in light of the seller's representations and warranties
• an estimate, even a provisional one, of the amount of the loss
• the supporting documents available (audit notice, reassessment notification, summons, formal demand)

A notification with gaps, which merely announces a claim without quantifying or documenting it, may be held unenforceable against the seller if the contract requires those details. The buyer's strategy is to give notice with enough supporting material to be valid, while reserving the possibility of supplementing the estimate, since the final amount of a reassessment or an award is often not known when the expiry deadline approaches.

The form and the means of notification

The protocol almost always requires a formal means: registered letter with acknowledgement of receipt, sometimes combined with service by a bailiff (huissier de justice, now commissaire de justice). Scrupulous compliance with the prescribed means is essential. A notification by email, where the contract requires a registered letter with acknowledgement of receipt (LRAR), exposes the buyer to inadmissibility even if the seller did in fact become aware of the claim.

The notification address calls for particular care. The address-for-service clause designates the address to which the notice must be sent. A seller who has moved without notifying a change of address cannot rely on non-receipt if the buyer used the contractual address. Conversely, a buyer who notifies to the wrong address runs the risk of forfeiture. The burden of proving that the notice was sent, and when, lies on the buyer, which means keeping all acknowledgements of receipt and service reports.

Expiry deadlines: the cardinal constraint

Enforcement of an asset and liability warranty runs up against two sets of time limits that must never be confused: the contractual expiry deadlines and the statutory limitation period.

The contractual period for which the warranty survives

The protocol provides for a duration of the warranty, often called the survival period or the duration of the warranty. After that period, no notification is admissible. Practice frequently adopts a duration aligned with the periods during which the authorities may reassess tax and social security matters, so that the warranty covers the whole period during which a reassessment remains possible. Some agreements provide for differentiated durations: a longer period for tax and social security liabilities, a shorter one for commercial or environmental liabilities.

This contractual period is an expiry deadline (forclusion): its lapse extinguishes the right to act, with no possibility of interruption or suspension other than as provided by the contract itself. This is the classic trap of liability warranty litigation. A buyer who lets the deadline pass, even by a few days, loses its warranty irreversibly, even if the liability is established and its origin is unquestionably prior to the sale.

The limitation period for the action for payment

The period for notifying the claim (a contractual period) must not be confused with the period for bringing proceedings to compel the seller to pay (limitation). Once notification has been properly given within the contractual period, the action for payment of the indemnity is subject to the general limitation period under Article 2224 of the French Civil Code, that is, five years from the day on which the right holder knew or should have known the facts enabling it to exercise that right.

In other words, notifying in time is not enough: if the seller refuses, court or arbitration proceedings must still be commenced before the five-year limitation period expires. A diligent buyer, faced with a seller who disputes or procrastinates, does not rest on having given notice: it monitors the starting point of the limitation period and interrupts it in good time, by a summons or by the interrupting acts provided for in Articles 2240 et seq. of the French Civil Code (acknowledgement of the debt by the debtor, court claim, protective measure).

Interplay with the reassessment procedure under way

A recurring difficulty is the gap between the discovery of the claim and the final determination of the liability. A tax audit may extend over several months, or even years, between the audit notice, the reassessment proposal, the reply to the taxpayer's observations and the commencement of recovery. The buyer must give notice as soon as the matter comes to light, often on receipt of the audit notice, without waiting for the final amount. Well-conceived clauses provide for an initial protective notification, followed by a supplementary notification once the liability has been quantified. Absent such contractual flexibility, safety dictates giving notice early and supplementing it afterwards.

Escrow and security for the warranty

An asset and liability warranty is worth only as much as the seller's solvency at the time it is called upon. A seller who has received the price and dissipated it, or who has arranged its own insolvency, leaves the buyer holding a worthless claim. Hence the importance of the security backing the GAP, often grouped under the expression security for the warranty or guarantee of the GAP.

How escrow works

Escrow (séquestre) consists of depositing a portion of the sale price with a third party (a lawyer, notary, bank or professional escrow agent) for the duration of the warranty or part of it. If the warranty is called, the escrowed funds are used to pay the indemnity on the terms of the escrow agreement.

The drafting of the escrow agreement is decisive. It must specify precisely the conditions for release of the funds: release to the seller at expiry if no claim has been notified, release to the buyer if a claim is admitted or established by a court, and the fate of the funds in the event of a dispute. The most sensitive point is what happens to the escrow in the event of disagreement: the escrow agent then retains the funds until a court decision or arbitral award is made, which ties up the sum for the whole duration of the liability warranty litigation.

Alternatives to escrow

Other forms of security may reinforce or replace escrow:

• the independent first-demand guarantee (garantie autonome à première demande), governed by Article 2321 of the French Civil Code, which allows the beneficiary to obtain payment on simple demand, without the guarantor being able to raise defences arising from the underlying contract
• the bank surety, which is more flexible but leaves room for debate on whether the call is well founded
• the first-demand guarantee issued by a credit institution, particularly sought by funds for its liquidity

The independent first-demand guarantee offers the buyer superior security: it is independent of any dispute on the merits of the claim. A seller who disputes the claim will have to bring an action for repayment after payment, which reverses the burden of the litigation and the balance of power. Investment funds favour this structure where the seller's financial standing is uncertain.

The seller's challenge: anticipating the defences

A seller who receives a GAP claim notice has an arsenal of defences that the buyer must anticipate when drafting the protocol and preparing the notification.

Challenges to formalities and deadlines

The seller's first reflex is to raise a defect in the notification: notice that is late under the contractual period, insufficient content, non-compliant means, wrong address. These formal challenges are formidable because they can defeat the warranty without any examination of the merits. The buyer's answer is rigour: complying to the letter with the agreed formalities and securing proof of each step.

Challenges to the origin and the triggering event

The seller next disputes that the triggering event predates the sale, arguing that the liability originates in the buyer's later management. This debate calls for analysis of the legal cause of the liability and requires solid documentation: for a reassessment, the period audited and the grounds for the adjustment; for a dispute, the facts underlying the claim. The quality of the due diligence carried out before the sale and the precision of the representations and warranties given by the seller determine the outcome of this debate. On the conduct of the preliminary audit and the move from identified risk to contractual protection, see our analysis of legal due diligence on the acquisition of a company.

Challenges to quantum, and the operation of caps and deductibles

The GAP agreement almost always contains limitation clauses: an overall cap on compensation (often expressed as a percentage of the price), a deductible or trigger threshold (no compensation below a certain amount), an individual threshold per claim (de minimis), and sometimes a reduction of the warranty over time. The seller relies on these limitations to reduce or cancel the indemnity. The buyer must check, when giving notice, that the claim exceeds the trigger threshold and remains within the cap, while monitoring the cumulative effect of claims against the overall deductible.

The duty to inform and the handling of covered disputes

Many agreements require the buyer, when a third party (the authorities, an employee, a counterparty) makes a claim capable of engaging the warranty, to inform the seller, sometimes to involve it in the defence, or even to leave it in charge of the defence. Failure to comply with this duty of cooperation may be penalised by a reduction or loss of the warranty, the seller arguing that a better-conducted defence would have reduced the liability. The acquirer must therefore coordinate the GAP claim notice with the handling of the underlying dispute, complying with the notification and consultation obligations set out in the contract.

Litigation strategy for the buyer and the fund

Beyond compliance with formalities, enforcing an asset and liability warranty calls for a genuine procedural strategy that the buyer or fund must build from the start of the negotiations.

Securing the clause upstream

The best litigation is the kind that is won at the drafting stage. The buyer should negotiate a clause that refers to the triggering event and its origin rather than only to the date on which the debt arose, that provides for a protective notification followed by a supplement, that aligns the survival period with the tax and social security reassessment periods, and that is backed by a liquid security for the warranty (sufficient escrow or an independent first-demand guarantee). The jurisdiction clause or arbitration clause must also be weighed: arbitration offers confidentiality and technical expertise, but at a cost and with timescales that do not suit every case.

Choosing the right procedural ground

If the claim is disputed, several routes open up. A protective measure (protective attachment under Articles L. 511-1 et seq. of the French Code of Civil Enforcement Procedures) makes it possible to secure the claim where the seller threatens to arrange its own insolvency, provided the buyer shows a claim that appears well founded in principle and circumstances threatening recovery. Summary proceedings (référé) may be used where the obligation is not seriously contestable, in particular where there is an independent first-demand guarantee. On the merits, the summons for payment of the indemnity must be served before the five-year limitation period expires.

Evidence: building the file as you go

Liability warranty litigation is evidence-driven litigation. The buyer must document, from the performance of the protocol onwards, anything capable of supporting a claim: retention of the reference accounts, the data room, the representations and warranties, and the pre-contractual exchanges showing what the seller knew or should have disclosed. When a claim arises, traceability of the date of origin, of the quantification and of the defence steps taken determines success. An evidential file built methodically as matters proceed is worth more than a late reconstruction under pressure from the expiry deadline.

Conclusion

An asset and liability warranty has value only if it is called upon in the proper form and within the time limits. Litigation experience shows that most warranties that are lost are lost not for want of a real liability, but for want of a proper and timely notification: expiry deadline missed, non-compliant means of notice, insufficient content, or unanticipated insolvency of the seller. For the buyer, the fund or the acquirer, mastery of the GAP does not begin on the day of the claim; it is won in the drafting of the protocol and continues with rigorous monitoring of deadlines.

The recommendation is simple and demanding: from signing, enter in the monitoring calendar the expiry date of each survival period of the warranty, distinguish it from the limitation period for the action for payment, and check that the security for the warranty is actually liquid. At the first sign of a liability (audit notice, formal demand, summons served on a third party), give notice without waiting for the final amount, scrupulously respecting the contractual form, and have the step secured by an adviser before the claim notice is sent.

Frequently asked questions

What is the difference between the notification period and the limitation period for an asset and liability warranty? The notification period is a contractual expiry deadline: it fixes the period during which the buyer may notify a claim to the seller. Missing it extinguishes the warranty definitively. The limitation period, governed by Article 2224 of the French Civil Code (five years), governs the court action to obtain payment of the indemnity once the claim has been properly notified. Both must be observed: notify within the contractual period, then bring proceedings within the limitation period if the seller refuses to pay.

Is a GAP claim notice sent by email valid? Only if the protocol permits that means. Most agreements require a registered letter with acknowledgement of receipt, sometimes combined with service by a commissaire de justice (bailiff). A notification by email where the contract requires an LRAR may be held unenforceable against the seller, even if it did in fact become aware of the claim. Complying to the letter with the prescribed formalities is the buyer's first protection.

What happens if the amount of the tax reassessment is not yet final when the warranty period expires? The buyer must give notice as soon as the claim comes to light, generally on receipt of the audit notice or the reassessment proposal, without waiting for recovery to commence. Well-drafted clauses provide for an initial protective notification, supplemented later once the liability has been quantified. Absent such flexibility, safety requires giving notice early and refining the figures afterwards.

Is escrow mandatory in an asset and liability warranty? No, escrow is not a legal requirement; it is a negotiated security. It consists of depositing a portion of the price with a third party for the duration of the warranty. It may be replaced or supplemented by an independent first-demand guarantee (Article 2321 of the French Civil Code) or a bank surety. Without security for the warranty, the buyer remains exposed to the risk of the seller's insolvency at the time it calls on the GAP.

Can the seller refuse to pay by relying on a formal defect in the notification? Yes, and it is one of its most effective defences. The seller may raise late notification, insufficient content, non-compliant means or a wrong address to defeat the warranty without any discussion on the merits. The buyer's answer is to comply rigorously with the agreed formalities and to keep proof of each step (acknowledgements of receipt, service reports).

To whom must the liability warranty indemnity be paid: the company or the buyer? It depends on the nature of the clause. A restoration warranty provides for payment to the target company, whose net assets are thus restored for the indirect benefit of the buyer as shareholder. A value warranty provides for direct payment to the buyer, reducing the acquisition price. The protocol must settle this point expressly, as it has different tax and practical consequences. Absent a clear provision, the question itself becomes a source of litigation.

Should an investment fund favour the independent first-demand guarantee? For a fund concerned with liquidity and security, the independent first-demand guarantee has a decisive advantage: it allows payment to be obtained on simple demand, regardless of any dispute on the merits of the claim. A seller who disputes the claim will have to bring an action for repayment after payment, which reverses the burden of the litigation. This structure is particularly recommended where the seller's financial standing is uncertain or hard to assess over time.
