Notarial Documents in Québec: Why They're Required

You're signing a purchase agreement, a power of attorney, a partnership commitment — and suddenly, you're asked for a notarial deed. Why must this particular document go before a notary, when a simple written contract suffices in other circumstances? The answer has less to do with administrative formality than with the very nature of what you're signing and the effects that deed must produce over time.

Two Types of Documents, Two Levels of Legal Weight

The Private Document

A private document is one drafted and signed by the parties themselves, without the involvement of a public officer. It is entirely valid in many situations: service contracts, residential leases, repayment agreements between individuals. Its value rests on the good faith of those who sign it and, in the event of a dispute, on what each party can prove.

The Authentic Deed

An authentic deed, on the other hand, is received by a notary acting as a public officer. Under Quebec law, such a deed is proof of its contents with respect to all — it is said to be opposable to third parties. This means that a creditor, an heir, or a third party cannot simply deny the existence or content of that deed. It is this particular evidentiary force that justifies the notary's involvement for certain specific acts.

When Quebec Law Requires Notarial Form

In several situations, the law requires that the deed be made before a notary — otherwise, it is null. Among the most common:

  • Immovable hypothec: any hypothec on an immovable must be made before a notary, en minute, otherwise it is null.
  • Donation: a donation must be made before a notary. The only exception is the gift of a movable property delivered immediately to the recipient, such as a gift given by hand.
  • Marriage contract or civil union agreement: it must be made before a notary, as must any subsequent amendments.
  • Certain renunciations: renouncing family patrimony, the partition of the acquests, or a succession is done before a notary or before the court.
  • Amicable dissolution of a civil union: when both spouses are in agreement, it is done by way of a joint declaration before a notary.

When a notary is not required but is strongly recommended:

  • Sale of a house or land: the law does not require a notarial deed, but it is the norm. The notary verifies the titles, ensures the immovable is free of debts, and promptly publishes the sale.
  • Notarial will: unlike a will written by hand or made before witnesses, it does not need to be probated after death. This accelerates the settlement of the succession, and there is no risk of it being lost.
  • Protection mandate: it may also be made before two witnesses, but when made before a notary, it is kept in a secure location and easy to retrieve. In all cases, it will need to be homologated if the person becomes incapacitated.

Me Petrulian will explain the details applicable to your situation during your consultation.

When Notarization Is Strongly Recommended Without Being Strictly Required

Some deeds are not legally required to be in notarial form, but having them notarized offers additional protection. A shareholders' agreement, an acknowledgment of debt, or a general power of attorney may be drafted as private documents — but the presence of a notary ensures that the parties have fully understood what they are signing, that their consent is free and informed, and that the document is securely preserved in the greffe. In the event of a future dispute, the difference is significant.

What Concretely Happens During a Signing Before a Notary

Signing a notarial deed is not a mere validation formality. The notary begins by verifying the identity of each signatory. They then ensure that the parties understand the scope of what they are about to sign, by reading the deed aloud and answering questions. The notary gathers each party's consent, then signs and seals the deed. The original — called the minute — is permanently preserved in the notary's greffe. The parties receive certified true copies.

This preservation in the greffe is an important particularity: even if you lose your copy, the original deed remains accessible. In Laval as elsewhere in Québec, this rule applies uniformly to all notaries practising in private practice.

Frequently Asked Questions

Do all contracts need to be signed before a notary in Québec?

No. Quebec law requires notarial form only for certain specific acts. For other documents, notarization remains possible and is often recommended, but it is not always mandatory.

What is the difference between a notarial deed and an ordinary contract?

A notarial deed is received by a notary acting as a public officer and carries evidentiary value recognized under Quebec law, which distinguishes it from a contract signed between individuals without the involvement of a public officer. A notary can explain the concrete effects of this distinction as they apply to your situation.

What happens if you sign a document that should have been notarized without going before a notary?

Under Quebec law, a deed that should have been received in notarial form but was not may be invalid or may not produce the intended legal effects. The appropriate course of action in such a case warrants a consultation with a notary.
