Liability of Notaries

Overview

Quebec notaries (notaires) occupy a distinctive position in the civil-law legal landscape. As public officers charged with receiving authentic acts (actes authentiques), managing trust accounts, and counselling all parties to a transaction, they bear professional responsibilities that have generated extensive litigation, particularly in real estate and hypothecary lending. The Supreme Court of Canada's landmark decision in Roberge c. Bolduc confirmed that notaries are held to an obligation of means (obligation de moyens) while also clarifying that compliance with current professional practice is no defence when the practice itself is unreasonable. This lesson examines the nature and intensity of the notary-client relationship, the specific duties of notaries, the evolution of the subsidiarity doctrine, and the conditions under which notaries may incur liability toward third parties.

Learning Objectives

Explain the default intensity of notarial obligations and identify circumstances that give rise to an obligation of result (obligation de résultat).
Apply the Roberge standard to evaluate whether a notary's reliance on professional practice constitutes reasonable conduct.
Identify the principal duties of notaries: authentication, counsel, title examination, and trust fund management.
Analyze the evolution and current status of the subsidiarity doctrine in notarial liability.
Determine when a notary may be liable toward third parties on an extra-contractual (responsabilité extracontractuelle) basis.

Key Concepts and Definitions

Notary (notaire): A public officer authorized to receive and authenticate acts, provide legal counsel, and manage trust accounts under the Notarial Act (Loi sur le notariat, hereinafter "L.n.").
Authentic act (acte authentique): A deed received by a notary in accordance with prescribed formalities, endowed with the evidentiary authority of a public document.
Obligation of means (obligation de moyens): A duty to exercise reasonable prudence and diligence without guaranteeing a specific result.
Obligation of result (obligation de résultat): A duty to deliver a specific, determined outcome; failure raises a presumption of fault absent force majeure.
Mandate (mandat): A contract by which one person empowers another to represent them in the performance of a juridical act with a third party (art. 2130 CCQ).
Duty to counsel (devoir de conseil): The obligation to inform, advise, and protect the parties regarding the nature and consequences of their juridical acts.
Title examination (examen de titres): A review of the chain of title to verify the validity, legal effects, and capacity of the parties to each transaction in the property's history.
Trust account (compte en fidéicommis): An account holding client funds, governed by the L.n. and Chambre des notaires directives.
Subsidiarity of recourse (subsidiarité du recours): The now-rejected theory that a client was required to exhaust remedies against the principal debtor before suing the notary.

The Nature of the Notary-Client Relationship

Mandate vs Professional Services Contract

The legal characterization of the relationship between a notary and a client remains a matter of doctrinal debate. Under the former Civil Code of Lower Canada, art. 1732 C.c.B.-C. expressly subjected notaries to the general rules governing mandate insofar as those rules could apply. Several notarial activities fit within the mandate framework: negotiating a loan, conducting a real estate transaction, or distributing funds according to client instructions all involve the notary acting as a representative.

The characterization does not, however, extend to every notarial function. When a notary receives an authentic act, s. 11 L.n. requires the notary to "act with impartiality and to counsel all the parties to an act," which prevents the notary from representing any single party. Art. 2138 CCQ further requires a mandatary to "act honestly and faithfully in the best interest of the mandator," a standard that sits alongside the impartiality requirement without overriding it. When the notary acts purely as a legal adviser, no representation occurs, and the definition of mandate under art. 2130 CCQ does not apply.

Some commentators classify certain functions, such as title searches, as professional services contracts, or even as contracts sui generis. As one author has observed, "the accuracy of this characterization depends on the particular role played by the notary for each specific act and therefore on the specific type of obligation assumed." A blanket label is therefore inappropriate. The distinction matters in practice because the applicable rules of liability, the intensity of the obligation, and the available defences vary depending on whether the governing contract is qualified as mandate, professional services, or another nominate contract.

Intensity of the Obligational Bond

Obligation of Means as the Default

Quebec law recognizes that notaries are held, as their baseline obligation, to an obligation of means. In Legault c. Thiffault, the Court of Appeal stated that notaries are "obligated to render attentive, diligent and competent services to their clients, giving wise and judicious advice insofar as it is reasonable to expect from a practitioner of ordinary competence." The Supreme Court confirmed this framing in Roberge c. Bolduc, noting that notaries owe their clients "an obligation of diligence."

To establish fault (faute), the plaintiff must demonstrate that the notary departed from a standard of reasonably prudent and diligent conduct assessed in light of the circumstances. The standard is objective: it measures the notary's conduct against that of a hypothetical notary of ordinary competence, not against the defendant's subjective intentions.

When an Obligation of Result Applies

In specific circumstances, the obligation rises to one of result. The jurisprudence identifies three principal situations:

The notary received a clear and precise mandate to "procure a valid authentic act" for the client.
The notary was instructed to disburse funds according to specific terms.
The notary accepted a "mandate in very specific terms," the performance of which admits of no discretion.

In these cases, mere proof of non-performance creates a presumption of fault. The notary must invoke force majeure or another recognized defence to escape liability. The obligation to sign the authentic act once all required formalities are completed is also generally treated as an obligation of result.

Professional Practice and the Roberge Standard

The Supreme Court's decision in Roberge c. Bolduc provoked considerable concern within the notarial profession. Some commentators, including Me Desjardins, interpreted it as transforming the obligation of means into an obligation of result. That reading is incorrect.

Roberge holds that compliance with current professional practice does not automatically exonerate a notary if the practice itself is unreasonable. The Court stated: "it is not sufficient to follow current professional practice to escape liability. The reasonableness of the practice must be demonstrated." The decision confirms that the concept of the reasonably prudent and diligent notary is an abstract standard that may diverge from the aggregate of prevailing individual practices.

The Court of Appeal subsequently formulated a complementary principle: a notary who fails to follow current professional practice likewise does not escape liability. In one case, a directive of the Chambre des notaires du Québec was held to "confirm an elementary measure of prudence." In a different case, however, a notary was found not liable despite departing from the standard-form contracts proposed by the Chambre.

The reconciliation lies in a two-step analysis proposed by Professor Marquis. The notary of ordinary diligence must first assess whether the practice is reasonable. If the practice is unreasonable, the notary should disregard it. If the practice is reasonable, the notary should adopt it or risk civil sanction. The difficulty, as Professor Marquis acknowledges, is that "the reasonableness of the practice will not always be easy to establish."

The Role of Expert Evidence

Roberge also settled an important point on the evidentiary weight of expert testimony. The Supreme Court stated that "the judge remains the final arbiter" and that "the testimony of an expert does not bind the court on the precise question of law the judge is called upon to decide."

Whether expert evidence is required to prove notarial fault remains debated in the case law. Some decisions hold that a judge may rule on the character of an error without expert witnesses. Others suggest expert evidence is necessary where proof of an established practice is at issue. The simple production of a doctrinal article, standing alone, does not suffice to establish the content of professional practice.

The Notary's Duties Toward Clients

The notary owes several distinct duties to clients. Breach of any one may ground liability where the three conditions of civil responsibility (fault, damage/préjudice, and causation/lien de causalité) are established.

Authentication of Acts

Section 10 L.n. defines the notary's public-officer mission:

The notary is a public officer... In his capacity as public officer, the notary's mission is to receive the acts to which the parties must or wish to give the character of authenticity attaching to acts of public authority, to ensure the date thereof, and, in the case of acts received en minute, to keep them on deposit in a greffe and to give communication thereof by issuing copies or extracts of such acts.

To fulfil this function, the notary must observe prescribed formalities. These include:

Inscribing the date and place of execution.
Drafting clauses that translate the parties' juridical intention.
Refraining from including any statement that is false or prejudicial to a party.
Correctly designating the immovables, lots, or discharged loans.
Reading the act aloud to the parties.
Verifying the identity, quality, and capacity of the parties by all reasonable means.
Collecting signatures and, where required, obtaining a solemn declaration.
Signing the act personally.

The obligation to produce a valid authentic act, once all required elements are assembled, is generally characterized as an obligation of result.

After authentication, the notary must, in certain circumstances, ensure follow-up by observing formalities relative to the effectiveness and publication (publicité) of the deed. One court has clarified that although the notary is not obligated to publish every act, the notary must at minimum "inform clients of the formalities required to preserve the legal effect of the acts received." In hypothecary matters, a reasonably prudent and diligent notary must inform the client of the limited duration of a movable hypothec (hypothèque mobilière) or risk committing a fault by omission in the duty to counsel.

Where it is possible to infer the parties' true intentions and reflect them in a corrected instrument, a demand for inscription en faux may allow the notary to limit or avoid engaging professional liability.

The Duty to Counsel

The duty to counsel (devoir de conseil) has been defined as:

a moral and legal obligation incumbent on the notary to enlighten the parties, according to their respective needs and the particular circumstances of each case, as to the nature and juridical, and sometimes economic, consequences of their agreements, as well as the formalities required for their validity and effectiveness.

This is an obligation of means that encompasses duties of information, recommendation, and protection. The obligation may be solidary or in solidum. Its scope is especially broad when the notary is aware of problems affecting the transaction. As an impartial public officer, the notary owes this duty to all parties to the act and cannot function as a mere drafter. The notary must verify that the parties understand the foreseeable juridical consequences of the instrument and must prevent any party from becoming the unwitting victim of the other's manoeuvring.

The intensity of the duty to counsel varies according to several factors:

The notary's familiarity with the type of transaction.
Information supplied by the client.
The significance or novelty of applicable regulations.
The scope of the mandate.
The parties' language proficiency, education, business experience, and age.
Whether the client obtained independent legal advice.
The existence of a long-standing business relationship, which intensifies the duty.

The duty is not perpetual. Absent a specific agreement, notaries are not required to maintain a "legal watch" (veille juridique) over their clients' affairs. The modesty of fees has also been considered as a factor of relativity.

The notary is entitled to assume that the parties possess the most elementary legal knowledge. The notary is not required to inform a buyer of the price paid by the vendor or to evaluate the risks of a loan. A client's own experience may weigh against a claim of insufficient advice, and the Court of Appeal has confirmed that the obligation to mitigate damages remains one of means: the creditor must have behaved as a reasonably prudent and diligent person.

A notary is liable for ignorance of established legal principles and settled jurisprudence. Where the law is uncertain, however, the notary will only be found at fault for adopting "a line of conduct that a reasonable, diligent, and prudent notary would not have adopted." If the notary's chosen position is later overturned by the courts, no liability attaches provided that position was reasonable at the time. Doctrine and jurisprudence require courts to situate themselves at the time the advice was given, not to judge retroactively by reference to subsequent developments. The notary must also, like the advocate, "inform clients of the consequences and risks of each divergent opinion."

Mini-hypo: A notary is retained to prepare a hypothecary loan secured by a movable. The notary fails to advise the client that the hypothec must be renewed within a statutory period or it will lapse. The hypothec expires, the borrower defaults, and the lender loses priority. The notary's omission constitutes a fault in the duty to counsel, and the lender may claim damages for the lost security.

Title Examination

A title examination (examen de titres) consists of reviewing the chain of transactions listed in the index of immovables and analyzing each act to assess its validity, legal effects, and the capacity of the parties. As the Court of Appeal has stated, a notary preparing a contract cannot "leave irregularities and contradictions likely to undermine title effectiveness and create the very ambiguity the notary is ordinarily charged with dispelling."

Title examination is generally classified as an obligation of means, a position confirmed by both doctrine and jurisprudence. A notary who relies on a summary verification, accepts incomplete or verbally communicated information, or omits the verification entirely (unless the task was excluded from the mandate) will be considered negligent. The notary must attend in person at the registry office (bureau de la publicité des droits).

Certain wording in title reports drafted by notaries may have the legal effect of imposing an obligation of result or even of guarantee on the practitioner. A thirty-year title search may be insufficient if indicators suggest defects predating that period. Relying on title searches performed by previous notaries for earlier transactions, or allowing their errors to persist, does not discharge the examining notary's own obligation. Reasonable reliance on a land surveyor's certificate (certificat de l'arpenteur-géomètre) may, however, constitute a ground of exoneration.

Where no certificate of location is available, the notary should inform the clients of its absence.

Mini-hypo: A notary preparing a deed of sale performs a thirty-year title search and finds no irregularity. However, the index of immovables contains references to a pre-1960 judgment affecting the lot boundaries. The notary does not investigate further. A boundary dispute later emerges. The notary may be held negligent for failing to extend the search beyond thirty years in the presence of indicators suggesting earlier defects.

Trust Account Management

Under the L.n., notaries hold funds on behalf of other persons. The notary must respect client instructions regarding the deposit and remittance of these sums, or make appropriate recommendations where instructions are lacking. Subject to the qualifications established in Roberge, the notary should follow the practices recommended by the Chambre des notaires, as these directives often confirm elementary measures of prudence.

Failure to retain funds sufficient to pay a preferential hypothecary claim pending execution of the discharge or release constitutes a fault. Recent decisions have recognized, however, that a minor procedural infringement does not automatically engage the notary's liability.

The notary must refrain from acting as surety, borrowing from clients, or using trust account funds for personal purposes. Doing so exposes the notary to both civil liability for reimbursement and severe disciplinary proceedings.

Professional Secrecy and Conflicts of Interest

The notary's obligation of confidentiality (secret professionnel) is grounded in s. 9 of the Charter of Human Rights and Freedoms and s. 14.1 L.n. The notary may not disclose facts learned in the exercise of professional functions. A breach may give rise to disciplinary proceedings and civil liability, including claims for material or moral damages and, where applicable, punitive damages.

Impartiality is also mandatory. In case of a conflict of interest or a departure from impartiality, a civil condemnation may be pronounced.

Subsidiarity of Recourse Against the Notary

For many years, Quebec courts applied a rule of subsidiarity (subsidiarité): a client's recourse against the notary was considered premature until all remedies against the principal debtor and sureties had been exhausted. The rule applied even in cases of insolvency or bankruptcy of the debtor.

The doctrine began to erode in 1986. In Caisse populaire de Charlesbourg c. Lessard, the court expressed the view that subsidiarity had no serious basis in Quebec law, observing that there was a confusion between the proof of damage (préjudice) and the right to institute proceedings.

The Court of Appeal completed the reversal in Bourque c. Hétu:

The notary does not escape a direct recourse based on the general rules of contractual or extra-contractual liability. Once the conditions for their application are met, the notary must be held to pay the amount of the reparation without the client being required to first exercise another recourse and demonstrate the insolvency of the principal debtor.

A more recent Court of Appeal decision confirmed this position, rejecting any prior "obligation of discussion" (obligation préalable de discussion) with the principal debtor or sureties.

The subsidiarity of the fault does not entail the subsidiarity of liability. The distinction remains relevant at the stage of final apportionment: the principal debtor may be attributed 100% of the damages while the notary bears 0%, depending on the respective shares of fault.

Once the three conditions of liability (fault, damage, causal link) are satisfied, the client may proceed directly against the notary. Two caveats merit attention. First, a creditor who opts for a taking in payment (prise en paiement) in the principal file risks extinguishing the claim against the notary. Second, at least one decision has dismissed a recourse against a notary for a title defect (erroneous lot description) where no prior formal notice (mise en demeure) had been sent.

Liability Toward Third Parties

As a public officer, a notary may exceptionally incur extra-contractual liability (responsabilité extracontractuelle) toward third parties (tiers). This occurs when a failure to observe formalities related to authenticity produces adverse effects that become apparent only years later, causing damage to a person who was not a party to the original act. A deed of sale containing an error may, for example, prove prejudicial to a subsequent purchaser. Because no contract links the notary and the third party, the recourse is extra-contractual.

Such claims are relatively uncommon: subsequent purchasers typically retain their own legal counsel, who may detect the defect before the transaction closes.

A notary may also incur extra-contractual liability where advice given to a client leads that client to commit an unlawful act causing damage to a third party.
