When spouses cannot agree, most files resolve it through their respective lawyers negotiating from a third-party valuation rather than either spouse's own estimate, since a number one spouse produces is rarely one the other trusts.
If negotiation stalls entirely, the Court of King's Bench can be asked to weigh in, though most divorcing couples settle the listing price well before that becomes necessary once a credible number is on the table.
Joel Dyck provides that neutral, hand-reviewed valuation so both spouses are negotiating a listing price from the same starting point. Get your hand-reviewed valuation from Joel Dyck.
