Introduction

In Canada, proving a common-law relationship often requires a sworn written statement known as a statutory declaration common-law. Different federal and provincial programs and agencies accept specific formats for these declarations, and requirements can vary depending on the purpose—immigration, taxes, benefits or private institutions. This guide explains the types of statutory declarations commonly used, what each one is for, and what information they typically must contain, including the statutory declaration common-law. (Updated April 16, 2026) The statutory declaration common-law serves as a foundational document in establishing the legitimacy of a common-law partnership.

Key terms and how common‑law status is defined

“Common‑law” describes couples who live together in a conjugal relationship without being legally married. The definition and the proof required can differ between federal departments and provincial bodies, but two concepts are central:

• Duration of cohabitation: Many federal programs recognize a continuous cohabitation period of at least 12 months as establishing common‑law status.
• Conjugal relationship indicators: Financial interdependence, shared household responsibilities, and joint commitments (such as a lease or children) are used to verify the nature of the relationship.

Types of statutory declarations of common‑law union

Several forms of statutory declarations are used across Canada. The main varieties are tailored to particular government processes or general civil uses.

When dealing with legal matters, understanding the role of a statutory declaration common-law is crucial for both partners. This document can significantly impact various applications and processes where proof of relationship is needed.

1. Statutory declaration for immigration (federal form)

When applying for family sponsorships or other immigration benefits, applicants usually submit a federal statutory declaration that confirms the existence of a genuine conjugal relationship. This declaration must be completed by the partners, include accurate dates of cohabitation and relationship history, and be signed in front of an approved witness or official. Immigration authorities rely on these sworn statements alongside supporting evidence.

Each statutory declaration common-law is unique and must reflect the true nature of the relationship. Failing to accurately represent this can lead to complications in immigration processes.

2. General statutory declaration for civil and administrative purposes

For banks, employers, provincial programs or private matters, a general statutory declaration can be used to confirm common‑law status. These are flexible documents that state the relationship details and may be sworn before a commissioner for oaths, notary public, or other authorized official. The exact wording and supporting documents requested will vary by institution.

A general statutory declaration common-law is essential for various civil matters, and its acceptance can vary significantly across institutions.

3. Program‑specific statutory declarations

Certain provincial agencies, benefit programs or regulatory bodies may require a specific declaration form or additional proof tailored to their rules. These program forms often request similar facts—cohabitation dates, joint financial arrangements and household details—but in a format designed for the receiving agency’s processes.

When filing for certain programs, having a well-prepared statutory declaration common-law can streamline the process and help avoid unnecessary delays.

How federal and tax authorities define common‑law status

Two commonly referenced authorities are federal immigration offices and tax administrators. While they share the basic idea of a conjugal relationship established by cohabitation and shared life, there are differences in thresholds and proof:

Understanding how tax authorities view a statutory declaration common-law is important for compliance and benefit eligibility.

• Immigration: A continuous 12‑month cohabitation period is typically required to qualify as a common‑law partner for sponsorship and other immigration processes.
• Tax authorities: For income tax and benefit eligibility, the definition generally recognizes couples who have been living together in a conjugal relationship for at least 12 months or who are the parents of a child together. Agencies may request sworn statements plus documentary evidence.

What information should a statutory declaration include?

Most statutory declarations of common‑law union include the following elements:

The inclusion of the statutory declaration common-law in your documentation can enhance the legitimacy of your claims, especially for tax or immigration purposes.

• Full legal names of both partners
• Current residential address and length of time at that address
• Start date of the conjugal relationship and date cohabitation began
• Details of shared finances or property (bank accounts, lease, mortgage, bills)
• Information about children, if applicable
• A short account of the nature of the relationship and daily life together
• List of documents attached as supporting evidence (e.g., joint lease, utility bills, joint accounts)
• Signatures of both partners and the signature/seal of the authorized witness

How to prepare and sign a statutory declaration

Follow these practical steps to prepare a usable statutory declaration:

Ensure that your statutory declaration common-law is prepared according to the latest guidelines to ensure acceptance by relevant authorities.

• Gather supporting documents that show shared residence and financial ties, such as a joint lease, joint bank statements, shared utility bills, or government letters sent to both partners.
• Complete the relevant form or draft a clear declaration that covers the required elements listed above.
• Do not sign the declaration until you are in the presence of an authorized witness (a commissioner for oaths, notary public, or other designated official).
• Have both partners sign the declaration and have the witness complete their portion, include the date and apply any official stamp or seal required.
• Keep certified copies of the signed declaration and the supporting documents for your records and for submission to requesting agencies.

Validity, acceptance and common pitfalls

By being aware of the common pitfalls regarding a statutory declaration common-law, you can better prepare your documentation to meet agency requirements.

Statutory declarations are sworn statements and carry legal weight, but their acceptance depends on the receiving authority. Common issues include:

• Incomplete or contradictory information that raises doubts about the relationship.
• Lack of supporting evidence such as joint documents or utility records.
• Unsigned or improperly witnessed declarations.
• Using a declaration that is not the specific form required by a particular program or agency.

When in doubt, confirm the exact documentation required with the agency requesting proof of common‑law status and use the form they specify.

Inquiries regarding the requirements for a statutory declaration common-law should always be clarified directly with the agency to avoid misunderstandings.

Tips for stronger evidence

• Provide multiple types of supporting documents showing the same time period for cohabitation (e.g., lease plus bills).
• Include a concise narrative explaining shared financial arrangements and household responsibilities.
• If one agency requests a specific government form, use that form rather than a generic declaration.
• Retain certified copies and make additional copies before submitting originals when requested.

Conclusion

Statutory declarations are an important, legally recognized tool for proving common‑law relationships in Canada. Knowing which declaration to use and including clear, consistent supporting evidence will reduce delays and increase the likelihood your declaration will be accepted. Always check the exact requirements of the agency or program you are dealing with and sign only in front of an authorized witness. (Updated April 16, 2026)
