Equal information access is the second piece. Both spouses should see every offer, every showing note and every price discussion at the same time, rather than one spouse hearing details filtered through the other, which is where perceived unfairness usually starts even in an otherwise amicable file.
Decision-making should be structured the same way: listing price, offer acceptance and any price reduction typically need both spouses' written agreement, and keeping legal fees to the standard $800 to $1,500 usually means resolving disagreements through the agent rather than through separate lawyers.
Fair process, not just a fair number, is what keeps a divorce sale from becoming its own dispute. Get your hand-reviewed valuation from Joel Dyck.
