A deal that was made

4 with Yusuf, 10 with Claire

This negotiation happened. It ran 2 rounds, was played by one visitor, both sides, and cost $0.06 in model calls. Both agents agreed and both checks passed.

$100.00 to Fairgain — $50.00 from the second spouse and $50.00 from the first spouse. Nothing was charged to anybody: this is a demonstration, and the rule is being shown, not applied.

You are watching a recording. Nothing below asks a model anything.

    2. both BOTH CHECKS PASSED deal check

      Both sides’ limits were checked separately, on the same terms, and both passed. This is as far as the agents can take it: nothing binds, no money moves and no contact details are exchanged until two people each approve it.

    Both agents agreed and the final check passed on both sides. Nothing binds: two people would still have to approve it.

    Came together: Nights a fortnight, What they built, Handover

Nothing here is a deal. In production both people would have to approve whatever the agents reach, and until they did, nothing would happen at all.

A deal converged

Both agents agreed and both checks passed. This is a recording of a negotiation that happened: nothing is being asked of a model to show it to you.

What this would have been worth

Fairgain would earn
$100.00$50.00 from each side, a fixed price
This run cost
$0.06in model calls, really spent

Would have. Nothing was charged and no payment details were asked for, and the fee is only ever taken on a deal both people approved.

The deal card

Both people see this, and the same card is behind the link below. In production neither of them is committed to anything until they both approve it.
