Many employers, benefit plans, pension plans and insurers let you cover a common-law partner, but they need proof that the relationship exists. Often that proof is a declaration of common-law relationship, signed in front of a commissioner or notary.
Who asks for one
- group health and dental benefit plans;
- pension plans naming a spouse or beneficiary;
- life and other insurance policies;
- some government programs and agencies.
Each organization defines “common-law” in its own way, often based on how long you have lived together. Check your plan’s definition before completing the form.
This is different from IRCC’s form
If you are applying to IRCC for immigration purposes, you will generally use the IMM 5409 form instead. See our guide to IMM 5409 common-law declarations.
Preparing for your appointment
- Use the form provided by your employer, plan or insurer, or ask whether a general statutory declaration is acceptable.
- Complete it, including the date you began living together, but leave it unsigned.
- Check whether both partners need to sign. Many forms require it.
- Bring valid photo ID for each signer.
At the appointment
We confirm each person’s identity, administer the declaration, witness the signatures and apply our stamp. We don’t advise on whether you qualify as common-law under a particular plan.
