The answer

Do not infer signing authority from occupancy, contribution, family relationship, or one person's instructions. Current title, ownership structure, dower, any registered interests, court orders, powers of attorney, and the contract path need Alberta legal review to identify whose consent and signature are required.

Calgary-specific context

A jointly owned family home, an investment held as tenants in common, and a home with a non-owner spouse can present different Calgary sale and title questions even when everyone informally agrees that the property should be sold.

What to do next

Obtain current title and a written signer-and-instruction map from the closing lawyer before setting a launch or offer-acceptance process.
