Declaration relating to a foreign document: how to have it sworn?

A document issued abroad — a birth certificate, a diploma, a marriage certificate — isn't always accepted as-is by a Québec or Canadian organization. In some cases, a person must sign a declaration under oath explaining the document's origin or confirming certain facts surrounding it.

This declaration does not replace the official legalization or authentication of a foreign document when that is required — it instead attests to facts that the document alone cannot prove.

In what situations is it requested?

  • confirming that two documents refer to the same person despite a different spelling of the name;
  • explaining the absence of an equivalent document in the country of origin;
  • attesting that a copy matches an original that remains abroad;
  • accompanying a document for which the receiving organization requests additional confirmation.

Does this declaration replace a certified translation?

No. If the document is in a language other than French or English, the receiving organization generally requires a separate translation, sometimes itself accompanied by a declaration attesting to the accuracy of the translation.

What should the declaration contain?

  • the declarant's identity and their connection to the document;
  • a precise description of the foreign document concerned (nature, country, date);
  • the facts the declaration is meant to confirm;
  • a statement of truthfulness.

Can it be sworn online?

Yes, when the document and situation are eligible for remote oath commissioning, by videoconference.
