The Family Property Act works alongside the Homesteads Act to govern how the home and its equity eventually get divided, but division and the decision to sell are separate questions. Even a spouse entitled to only part of the proceeds still has to sign off before a listing goes live.
When one spouse refuses outright, the other can apply to the Court of King's Bench for an order permitting the sale, a process that adds real time and legal fees of roughly $800 to $1,500 on top of an already stressful separation.
A hand-reviewed valuation done early gives both spouses one agreed number to negotiate from instead of two competing online estimates, which is often what unlocks the consent in the first place. Get your hand-reviewed valuation from Joel Dyck.
