Statutory Declaration of Common-Law Union — Notarized Online
A formal declaration for couples living together but not legally married, commonly used for tax, insurance, or benefit purposes.
Many institutions — the CRA, employer benefit plans, insurers — require formal proof of a common-law relationship before extending benefits normally reserved for married couples. This declaration, sworn by one or both partners, provides exactly that.
Both partners can join the same video appointment if the declaration requires both signatures, or a single partner can sign if that is what the receiving institution asks for. Photo ID is verified for each signer.
Commissioned in accordance with O. Reg. 431/20. We do not advise on what qualifies as a common-law relationship under a specific institution's rules — please confirm their requirements before your appointment.
