The first practical step is agreeing on an accurate price, since a disputed number is the most common reason an otherwise cooperative sale stalls between two spouses who agree on everything else.
Coordinating possession date matters more in a divorce sale than in a typical sale, since both spouses often need the closing timeline to line up with separate moves rather than one household transitioning to another.
Each spouse retaining their own lawyer, at roughly $800 to $1,500 in legal fees, even for an uncontested sale, protects both sides if a question about the division of proceeds comes up after closing. Get your hand-reviewed valuation from Joel Dyck.
