Neutrality in practice means identical information reaching both spouses at the same time, a single valuation both agree reflects the home, and no private strategy conversations with one spouse that the other does not also have access to, all while each side's own lawyer, at $800 to $1,500 in fees, handles the legal side separately.
The Saskatchewan Real Estate Commission regulates licensees and requires that consent to represent more than one party in this way be documented, which protects both spouses if the arrangement is ever questioned later.
Whether neutrality actually holds up depends on the agent's conduct through the file, not just the paperwork signed at the start. Get your hand-reviewed valuation from Joel Dyck.
