Overview
About this document
- 01
What is a common-law partnership declaration?
A statutory declaration of common-law partnership — also called a common-law affidavit, proof of common-law relationship, or cohabitation declaration — confirms under oath that you and your partner are in a common-law relationship and live together.
Because there is no certificate for a common-law relationship the way there is for marriage, a sworn declaration is a common way to provide proof.
- 02
When you need proof of a common-law relationship
A sworn common-law declaration is requested in many tax, benefit, and immigration situations.
- Confirming common-law status to the Canada Revenue Agency for credits or benefits.
- Supporting a pension, survivor benefit, or insurance beneficiary claim.
- Adding a partner to workplace, health, or insurance coverage.
- Backing a spousal or common-law sponsorship application.
- 03
How long must you live together?
Different programs apply different thresholds. The Canada Revenue Agency generally treats you as common-law after living together in a conjugal relationship for 12 continuous months (or sooner if you share a child). Immigration and other programs may define it differently.
State your cohabitation start date accurately; the organization decides eligibility under its own rules, and may ask for supporting documents such as shared bills or a lease.

How to notarize a common-law partnership declaration in Ontario
After you fill in your common-law partnership declaration and download the PDF, do not sign it in advance. A sworn document must be signed in front of a notary public or commissioner for taking affidavits, who administers your oath or solemn affirmation first.
Minute Notary commissions your common-law partnership declaration online by secure video, under Ontario's remote commissioning rules (O. Reg. 431/20), or in person in Ottawa. Bring valid government-issued photo identification so we can verify your identity before applying the notary seal.
