In Ontario, a separation agreement does not need to be notarized to be valid or enforceable. Notarization is not a legal requirement for a separation agreement to hold legal weight. However, it can provide additional evidentiary support and may be recommended in certain situations.

Notarization involves having a document signed in the presence of a notary public, who then verifies the identities of the parties and witnesses the signing. The notary public also affixes their official seal or stamp to the document.

While notarization is not mandatory, parties may choose to have their separation agreement notarized for several reasons:

  1. Evidentiary Support: Notarization creates a strong evidentiary record of the signing and can help establish the agreement’s authenticity and validity in case of future disputes.
  2. Increased Perceived Legitimacy: Some individuals may view notarization as an additional layer of formality and legitimacy for the agreement. This can provide a sense of assurance and peace of mind.
  3. International Use: If parties plan to use the separation agreement in another jurisdiction or for purposes such as immigration or international travel, notarization may be required or preferred by the authorities in those jurisdictions.

It’s important to note that notarization does not automatically make an agreement more enforceable or legally binding. The key factors in the enforceability of a separation agreement are voluntary consent, independent legal advice, financial disclosure, and compliance with other legal requirements.
