Restitution of Performances: Principles, Modalities, and Third Parties

Overview

When a juridical act is retroactively annulled, the parties must be returned to the positions they occupied before the act was formed. The regime that governs this unwinding is called restitution of performances (restitution des prestations), codified in articles 1699 to 1707 of the Civil Code of Quebec (Code civil du Québec, CCQ). These provisions establish when restitution arises, how it operates between the original parties, and how it affects third parties who may have acquired rights in the interim. Any agreement modifying restitution remains subject to applicable mandatory rules and protected third-party rights. Particular rules tied to specific contexts, such as consumer protection or insurance, may supplement or displace this general framework.

Learning Objectives

After reading this article, the reader should be able to:

• Identify the circumstances that trigger an obligation to make restitution under Quebec civil law.
• Distinguish restitution in kind (en nature) from restitution by equivalence (par équivalent) and explain when each applies.
• Apply the rules governing total and partial loss of property subject to restitution, including the relevance of good faith (bonne foi) and superior force (force majeure).

Circumstances Giving Rise to Restitution

Article 1699 CCQ supplies the general restitution framework. The legal basis for the duty to return a performance depends on the triggering event, including:

• Annulment (nullité) of a contract, which retroactively destroys the juridical act (art. 1422, al. 2 CCQ).
• Resolution (résolution) of a contract for non-performance, which also operates retroactively (art. 1606, al. 1 CCQ).
• Fulfilment of a resolutory condition (condition résolutoire), which unwinds the contract from the date of formation (art. 1507, al. 2 CCQ).
• Impossibility of performance due to superior force, governed by the theory of risks (art. 1694, al. 1 CCQ).
• Receipt of a thing not due (réception de l'indu), where property or payment is received without right or through error (art. 1492 CCQ).

The regime also covers any situation where, by operation of law, a person must return what was received "without right or by error."

Illegality or immorality does not automatically bar restitution. Article 1699, paragraph 2 permits exceptional refusal or adjustment where the ordinary result would confer an undue advantage. JurisClasseur treats the former maxim nemo auditur propriam turpitudinem allegans within this statutory analysis, rather than as an automatic prohibition (fasc. 15, paras. 5–6).

Judicial Discretion Under Article 1699

Under art. 1699, al. 1 CCQ, the court is bound to order restitution whenever a juridical act is retroactively destroyed. In exceptional cases, art. 1699, al. 2 CCQ grants the court a discretionary moderating power to refuse restitution, or to modify its scope or conditions, where restitution would confer an undue advantage (avantage indu) on one party.

An undue advantage must be established concretely in the circumstances. It may arise from a party's blameworthy conduct or from another unjustified benefit produced by the ordinary restitution rules. The party seeking exceptional refusal or adjustment must establish its basis; that party may be either creditor or debtor of restitution.

Relevant factors include:

1. Apply the ordinary restitution rules to identify what each party must return.
2. Identify a concrete undue advantage resulting from that application.
3. Determine whether adjustment suffices or exceptional refusal is justified.

Example: After a buyer obtains annulment for the seller's fraud, the ordinary restitution accounting may still leave a concrete undue advantage to the seller. The court can consider an adjustment under article 1699, paragraph 2; the seller's fault alone does not establish the amount or automatically require full compensation of every loss.

This discretionary power must be distinguished from the calculation of fair value under articles 1701 and following CCQ. The court first applies the general restitution rules to determine the value of the property or service to be returned. Only after completing that assessment does the court consider whether an undue advantage results. The discretion under art. 1699, al. 2 CCQ is exercised on a case-by-case basis, not according to automatic rules or pre-established formulas.

Unilateral and Bilateral Restitution

Restitution may be unilateral or bilateral. In a case of receipt of a thing not due, only the recipient has an obligation toward the payor. In bilateral restitution, such as that following the annulment of a synallagmatic contract (contrat synallagmatique), each party must return what it received from the other. Where the conditions for compensation (compensation) under art. 1672 and 1673 CCQ are met, the court offsets the two reciprocal debts.

In bilateral restitution, each party must address what it must return, whether in kind or by equivalence. Appropriate offers may demonstrate readiness to perform; formal tender and deposit under articles 1573 et seq. CCQ are available where the circumstances call for them, but are not an automatic prerequisite to every restitution claim.

Restitution of performances must also be distinguished from reparation of civil fault under art. 1611 CCQ. Reparation requires proof of injury (préjudice) and operates under the principle of full compensation (réparation intégrale). In contractual non-performance, reparation typically takes the form of damages. Restitution, by contrast, requires returning what was received; it does not engage the question of compensating a loss.

Restitution Between the Parties

Restitution in Kind

Article 1700 CCQ establishes the baseline rule: restitution is made in kind by returning the actual property received. Restitution by equivalence is permitted only where restitution in kind is impossible or would cause serious inconvenience (inconvénient sérieux). The burden of proving impossibility or serious inconvenience rests on the debtor of the restitution obligation. A mere difficulty does not qualify; considerable transport costs, for example, may represent a serious inconvenience.

A consumed service or past occupation of leased premises cannot be physically returned and may require monetary restitution after annulment. The classification as a contract of successive performance does not mean that every performance is non-returnable: borrowed money, for example, must be accounted for separately from the use of capital. Resiliation generally operates only for the future, whereas annulment may require valuation of past performances (arts. 1422, 1606 and 1700 CCQ).

Example: A court annuls a lease. The tenant cannot return the months of occupation already enjoyed. The value of that occupation is assessed and forms the basis for restitution by equivalence.

As a general rule, restitution by equivalence is assessed as of the time the debtor received what must be restored, subject to the exceptions discussed below.

An inability to return the property in kind does not itself bar annulment or resolution. Article 1700 makes restitution by equivalence available, subject to the specific exceptions in the restitution regime, including superior force and protected persons.

Restitution by Equivalence Attributable to the Debtor

When restitution in kind is impossible for reasons attributable to the debtor rather than to superior force, different rules apply depending on whether the loss is total or partial. The Code distinguishes these two scenarios to calibrate the debtor's obligation according to the severity of the loss and the debtor's good or bad faith.

Total Loss of the Property

Article 1701, al. 1 CCQ addresses total loss or alienation of property (sale, exchange, giving in payment, donation) not resulting from superior force. The article distinguishes two categories:

1. Debtor in good faith: The debtor must return the lesser of the property's value at the time of its loss or alienation, the time of restitution, or the time of receipt.
2. Debtor in bad faith or whose fault caused the restitution (for example, through fraud or dol): The debtor must return the highest of those three values.

Bad faith or fault causing restitution changes the valuation rule. This is part of the statutory restitution accounting, not a general award of punitive damages.

Example: A buyer resells a painting received under an annulled sale. Its values at receipt, resale and restitution are proved to be $5,000, $6,000 and $8,000. A buyer in good faith who did not cause restitution by fault owes $5,000. A buyer in bad faith, or whose fault caused restitution, owes $8,000 under article 1701, paragraph 1.

Partial Loss of the Property

Under art. 1702 CCQ, when property subject to restitution has suffered deterioration or depreciation not resulting from superior force, the debtor must return the property in its present state and compensate the creditor for the loss. An exception exists where the deterioration results from normal use of the property, in which case no compensation is owed for the depreciation.

Example: A court resolves a sale of equipment. The buyer returns the equipment, which has deteriorated beyond normal wear. The buyer compensates the seller for the excess deterioration. As a result, the buyer's monetary restitution from the seller is reduced by the amount of that compensation.

Article 1702 must be read with the rules governing superior force, default and enjoyment of the property. JurisClasseur records interpretative qualifications concerning bad faith and normal use; the absence of an express distinction in article 1702 does not establish identical outcomes in every good-faith and bad-faith case (fasc. 15, para. 17 and its notes). Purely economic market fluctuations are distinguished from deterioration of the property.

A fraud victim may seek adjustment under article 1699, paragraph 2 if ordinary restitution would confer an undue advantage on the other party. The court must identify that advantage. Full reimbursement of the price despite every form of depreciation is not an automatic consequence of the other party's fault.

Article 1702 does not specify the valuation dates used for total loss in article 1701. Assessment of partial loss therefore requires evidence of the deterioration and the applicable measure; the lowest-or-highest-value rule cannot be stated as automatically governing partial loss.

Restitution by Equivalence Following Superior Force

Superior force requires an unforeseeable and irresistible event under article 1470 CCQ. An accidental fire or the absence of personal fault alone does not establish those conditions; the party invoking the exemption must prove them.

Loss by superior force: Under art. 1701, al. 2 CCQ, a debtor who loses the property through superior force is released from the obligation to make restitution. If the debtor receives or has the right to receive an indemnity for the loss (for example, insurance proceeds), the debtor must transfer that indemnity or the right to claim it to the creditor. Where the debtor acted in bad faith, or the debtor's fault caused the restitution, the debtor must make restitution by equivalence despite the superior force, unless the property would also have perished in the creditor's hands.

The effect on the other party's reciprocal restitution is more difficult. JurisClasseur notes disagreement about risk allocation where the property disappears through superior force after an act is retroactively undone (fasc. 15, para. 16, note 16). Article 1694 governs impossibility of contractual performance, but should not be presented as mechanically deciding every later restitution loss. The accounting must consider the indemnity transferred, fault and any established undue advantage.

Partial loss. Articles 1562 and 1702 CCQ must be read together when superior force damages rather than destroys the property. The debtor's default and good or bad faith may affect liability. Return of the damaged property does not automatically fix the reduction of the other party's repayment obligation; that issue requires a complete restitution analysis.

Ancillary Indemnities

Disbursements (impenses). Article 1703 directs the court to the rules for possessors in good or bad faith, including articles 931–933 and 957–963 CCQ, adapted to restitution. Necessary expenses must be reimbursed, subject to applicable accounting. For useful expenses still embodied in an immovable, article 959 permits reimbursement of the expenses or, at the owner's choice, the added value. Ornamental expenditure is not invariably excluded: under article 961, a good-faith possessor who leaves the work at the owner's choice receives the lesser of its cost and added value. Bad faith or fault causing restitution engages the corresponding less favourable rules.

Fruits and revenues: Under art. 1704 CCQ, a debtor of restitution keeps the fruits and revenues (fruits et revenus) produced by the property and bears the costs incurred to produce them. A debtor in bad faith, or one whose fault caused the restitution, must return the fruits and revenues and compensate the creditor for the enjoyment (jouissance) the property provided, after offsetting production costs.

Enjoyment of the property. A debtor in good faith generally owes no indemnity for enjoyment, except when enjoyment was the principal object of the performance or the property was liable to depreciate rapidly. A debtor in bad faith, or whose fault caused restitution, must compensate the creditor for enjoyment (art. 1704 CCQ). The Code does not establish separate categories of a lesser use value and a greater enjoyment value simply according to whether the contract was immediate or successive.

Costs of restitution. The parties bear restitution costs in proportion to the performances returned. A party in bad faith, or whose fault caused restitution, bears those costs alone (art. 1705 CCQ). Litigation costs and damages require their own legal basis.

Restitution Limited to Enrichment

Article 1706 CCQ limits restitution by minors, persons of full age under tutorship, and persons of full age under a protection mandate to the enrichment they retain. The person seeking restitution bears the burden of proving that enrichment. The current wording expressly includes protection mandates.

Example: A minor receives $2,000 under an annulled transaction. The evidence establishes that $1,000 was dissipated without any retained benefit and that $1,000 remains. Subject to the intentional-or-gross-fault exception, monetary restitution is limited to the retained enrichment. Spending on necessities cannot automatically be treated as lost enrichment, because it may have saved other expenditure.

Several qualifications apply to this protection:

• The article expressly concerns minors and adults under tutorship or a protection mandate; incapacity alone does not establish every condition for this protection.
• Full restitution may be ordered if the protected person's intentional or gross fault made restitution impossible.
• JurisClasseur explains that the enrichment limit concerns situations where restitution in kind is impossible; property still available must in principle be returned.
• Retained enrichment requires a factual assessment, including any enduring benefit or saved expense.

For an act predating the protective measure, examine the applicable annulment and protection provisions and the person's situation at the relevant time. Later establishment of a measure should not be described as making article 1706 automatically retroactive in every case.

Worked Example: Annulled Sale of Heavy Equipment and Restitution by Equivalence

Factual Scenario

Entreprises Minieres Boreales purchased a heavy articulated rock truck from Equipements Lourds du Nord Inc. for $420,000. Six months into operations, the Superior Court declared the contract relatively null for vendor fraud (dol, art. 1407 CCQ) due to intentional falsification of chassis stress logs.

Two weeks prior to the judgment, an accidental fire originating in an adjacent third-party welding facility swept through the mine yard, completely incinerating the truck. Boreales had spent $35,000 replacing the hydraulic transmission shortly after delivery to preserve the asset, and had generated $80,000 in commercial hauling revenue while operating the machine. Equipements Lourds demanded full restitution by equivalence of the $420,000 sale value and disgorgement of the $80,000 revenue. Boreales demanded the immediate reimbursement of its $420,000 purchase price and $35,000 transmission expenditure. Boreales had received $190,000 in casualty insurance proceeds for the burned vehicle.

Effects of Restitution on Third Parties

Third parties who acquired rights through a transaction that is retroactively annulled cannot, in principle, hold greater rights than their predecessors in title (auteurs). They are, therefore, ordinarily affected by the annulment. The Code, however, introduces distinctions based on the character of the third party's transaction and the third party's good or bad faith.

Alienation for Value

An alienation for value to a third party in good faith is opposable to the person entitled to restitution (art. 1707, para. 1 CCQ). Restitution between the original parties can therefore proceed by equivalence. The amount follows article 1701: the lower statutory value applies to the debtor in good faith; the higher applies if the debtor was in bad faith or caused restitution by fault. The third party's good faith does not determine the original debtor's valuation rule.

The person entitled to restitution bears the burden of proving the third party's bad faith to defeat protection under article 1707. A third party shown to be in bad faith is subject to restitution in kind or, if return is impossible, by equivalence.

Example: A sells a car to B, and B resells it to C. If A obtains annulment of the first sale and C purchased in good faith for value, A cannot recover the car from C. A receives monetary restitution from B.

Gratuitous Alienation

A gratuitous alienation (aliénation à titre gratuit), such as a donation, receives less protection. It is not opposable to the person entitled to restitution, even where the third party acquired in good faith. The third party must return the property, subject only to the rules of prescription (prescription) under art. 2910 CCQ and following.

Acts Other Than Alienation

Under art. 1707, al. 2 CCQ, acts other than alienation concluded for the benefit of third parties in good faith are opposable to the creditor of restitution. Restitution in kind by the debtor to the creditor may still proceed, but the creditor must respect the rights granted to the third party.

Example: A sells an immovable to B, who grants a lease to T. The sale between A and B is later annulled. T is the third party for article 1707 purposes, and a lease granted to T in good faith is opposable to A, subject to the applicable lease rules. Annulment of T's own lease would instead concern restitution between that lease's parties.

This distinction preserves third-party arrangements made in good faith while denying protection to bad-faith actors.

Worked Example: Resolution of Real Estate Transfer and Rights of Third-Party Acquirers

Factual Scenario

In this hypothetical example, Jean-Pierre sells a commercial parcel to Marc for $500,000, with $300,000 paid and a $200,000 balance. The deed contains a resolutory clause. Marc resells to Helene for $550,000 and defaults on the balance. Jean-Pierre seeks resolution and recovery of the land, alleging that his clause survives the resale.

The documents do not establish whether Jean-Pierre's rights were properly published, whether Helene had notice of the defect in Marc's title, or whether the statutory notice and time limits for resolution were respected. Those facts must be determined before assuming that a judgment of resolution can affect Helene.

Practice Checklist

• Confirm that a circumstance giving rise to restitution exists (annulment, resolution, resolutory condition, superior force, receipt without right).
• Determine whether restitution is unilateral or bilateral.
• Assess whether restitution in kind is possible or whether serious inconvenience warrants restitution by equivalence.
• If restitution is by equivalence, classify the loss as total or partial, and determine whether it is attributable to the debtor or to superior force.
• Identify the good or bad faith of each party and apply the appropriate valuation rule (least or greatest value) under art. 1701 CCQ.
• For partial loss, apply art. 1702 CCQ and consider the corrective mechanism of art. 1699, al. 2 CCQ where one party acted in bad faith.
• Account for ancillary indemnities: fruits, revenues, enjoyment, disbursements, and restitution costs under art. 1703 to 1705 CCQ.
• Determine whether any party is a protected person (minor or adult under tutorship or a protection mandate) entitled to limited restitution under art. 1706 CCQ.
• Assess the effects on third parties: classify the transaction as alienation for value, gratuitous alienation, or other act, and verify good or bad faith under art. 1707 CCQ.
• Consider whether restitution would confer an undue advantage on one party, warranting judicial intervention under art. 1699, al. 2 CCQ.
• Where required, use real tender and deposit (art. 1573 CCQ and following) to formally demonstrate readiness to make restitution.
