Can we each have our own person to talk to?
Yes, and it is more common than people expect. What we will not do is share your listing with an agent from another brokerage. What we will do, when it helps, is put two of our own agents on the file, one as each of your points of contact.
Both agents work the same file toward the same outcome, which is the best result for the two of you. Nobody is negotiating against anybody, because there is nothing to negotiate between you: the house is being sold once, at the best price the market will pay, and the proceeds are divided by your agreement. What changes is that each of you has your own person to call, ask the awkward question, and think out loud with, instead of feeling like you are sharing someone.
The transparency rule does not change when we do this. Facts about the house and the sale still go to both of you at the same time. What you tell your agent in confidence still stops with us, and is never carried across to the other party.
How the two agents work together
When an offer comes in, both agents receive it. Each one presents it to their own client and has that conversation privately, at whatever pace that person needs. Then the two agents come back together and work out what is in the best interest of the couple rather than one half of it. Counteroffers run the same way.
Between offers, we carry the traffic. Showing feedback, scheduling, offers, counteroffers, questions about the house itself: all of it moves between the two agents and out to each of you, instead of between the two of you.
That last part is the one people underestimate. A separating couple usually has to negotiate every small logistical thing directly, and every one of those exchanges is a chance for a hard week to get harder. We take them off your plate. It is far less complicated in practice than it sounds on paper.
If you want it set up this way, say so at the first meeting. It is easier to start there than to change partway through.
