A Specific Power of Attorney (Procuration spécifique) in Quebec is a formal legal mandate governed by articles 2130 to 2185 of the Code civil du Québec that authorizes a precisely designated person (the mandataire or attorney) to perform one or more specifically defined legal acts on behalf of the grantor (the mandant). This document is distinct from both a general power of attorney and a protection mandate: while a general mandate confers broad administrative authority, and a protection mandate is designed for incapacity planning, a specific power of attorney is a targeted instrument for a single transaction or precisely circumscribed set of acts.

The legal foundation of the specific power of attorney in Quebec civil law is the law of mandate (contrat de mandat), codified in articles 2130-2185 CCQ. Article 2130 CCQ defines a mandate as a contract by which a person, the mandant, empowers another person, the mandataire, to represent them in performing a juridical act with a third person. Article 2135 CCQ establishes a critical interpretive rule: a mandate expressed in general terms only confers the power to perform acts of simple administration. For any act of disposition or acts requiring specific authorization (such as selling immovable property, mortgaging, or making a gift), the mandate must expressly authorize the act.

Article 2136 CCQ reinforces the restrictive interpretation principle by stating that powers not expressly conferred by the mandate but necessary for the performance of the mandate's object are impliedly conferred, but all other powers are interpreted restrictively. This means a specific power of attorney for the sale of a property implicitly includes the power to sign ancillary documents related to the sale, but does not extend to selling other properties or managing unrelated affairs.

A specific power of attorney has several key characteristics that distinguish it from other mandate instruments. First, it is limited in scope: the attorney's authority is confined to the specific act described, and any action beyond that scope is null and without effect against the grantor (art. 2160 CCQ). Second, it is typically self-terminating: once the specific act is accomplished, the mandate naturally ends without formal revocation. Third, it takes immediate effect upon signing, unlike a protection mandate which requires court homologation.

The document can take various forms depending on the act authorized. For immovable property transactions — sales, purchases, or mortgages — a notarial specific power of attorney is typically required because the transaction must be published at the bureau de la publicité des droits (Quebec Land Registry). For other acts, a private written document is generally sufficient, though notarization provides additional legal certainty.

Protection of third parties dealing with an attorney is addressed by article 2163 CCQ, which provides that a mandant who has given a mandate cannot oppose it to a third party who contracted in good faith with the attorney, even if the mandate has been revoked or modified, unless the third party was aware of this. This provision protects the integrity of commercial transactions carried out by attorneys acting within their authority.

A specific power of attorney is the appropriate legal tool whenever a person is temporarily unavailable to sign or act in a specific legal matter that requires their signature or presence, but they are otherwise fully capable and wish to retain control over all other aspects of their affairs. The most common scenarios in Quebec involve real estate transactions: a property seller or buyer who is abroad or otherwise unable to attend the notarial signing of a deed of sale can grant a specific power of attorney to a trusted person who will attend in their place.

A specific power of attorney is also frequently used by business persons who need a representative to sign a particular contract during their absence from Quebec. It is appropriate for authorizing a tax professional to file a specific year's income tax return, for authorizing someone to manage a specific bank account during a hospitalization or extended absence, or for authorizing a representative to appear at a specific administrative or legal proceeding.

It is particularly valuable when a person wants to give a limited, defined authority to someone without granting broad management powers. For example, an elderly person who does not want to grant a full general power of attorney can use a specific power of attorney to authorize their child to sell their car or manage a specific bank account.

A specific power of attorney should be considered when the act requires a representative and the grantor cannot or does not want to be present, when the act is clearly defined and limited in scope, when the grantor wants to maintain control over all other affairs, and when the mandate should expire automatically upon completion of the act rather than requiring formal revocation.

A valid Quebec specific power of attorney under arts. 2130-2185 CCQ must contain several essential elements to be legally effective. The grantor's complete legal identification is the starting point, including full legal name, date of birth, domicile address, and occupation. Sufficient identification ensures the document can be relied upon by third parties dealing with the attorney.

The attorney's (mandataire's) complete identification — name, address, and relationship to the grantor — must be clearly stated. If a substitute attorney is designated (recommended in case the primary attorney cannot act), their identification must also be complete.

The authorized specific act must be described with maximum precision. Under article 2135 CCQ, general language is insufficient for specific acts of disposition. For real estate, this means identifying the property by complete address and lot number, specifying the type of transaction, and setting any financial limits. The description must be specific enough that a third party could understand exactly what the attorney is and is not authorized to do.

Ancillary powers necessary to complete the specific act should be explicitly listed. Without express mention, article 2136 CCQ requires restrictive interpretation, meaning powers beyond the main act and its necessary incidentals are excluded. Any specific exclusions — acts the attorney is expressly not permitted to perform even in connection with the main act — should be clearly stated.

The duration provisions must specify when the mandate takes effect, how long it lasts (typically until completion of the act, until a fixed expiry date, or until revoked), and any conditions affecting validity. If financial amounts are involved, a maximum authorized amount should be specified.

Remuneration terms under article 2134 CCQ (which presumes a mandate is gratuitous unless otherwise agreed) should be addressed explicitly. The place and date of signing complete the formal requirements. Notarization is required for immovable property transactions and is recommended for any act requiring publication or involving significant financial value.
