• Duration and details of the conjugal relationship (continuous years and dates);
• Joint financial or property arrangements, such as shared lease/mortgage/ownership, joint bank or credit accounts;

If you answered “no” to questions on joint documentation, you are asked to provide other documentary evidence showing your relationship.

Signing the Declaration

The statutory declaration must be signed in the presence of a person authorized to administer oaths (for example, a notary public). Both partners sign the declaration, and the administrator must also sign and provide their title.
