Now this story goes back quite a while.
Dougan, 51, agreed to pay the ex $15.3m in two installments. Fair enough. But he was 12 days late making the final payment in June 2006, so he threw in an additional $25,000 interest.
But here's the rub. Ms Dougan's lawyers then claimed that, under the terms of the settlement, if he was late with the final payment, Dougan would have to pay interest from the day the divorce settlement was signed (not just the 12 days he was late). And it's this $750,000 interest payment that is currently at issue, with the matter now before the Connecticut Supreme Court.
In addition to the $15.3m, Ms Dougan is also said to have received one of the couple's homes (worth around $10m), some small change ($143,000) and a 2000 BMW X5 (But don't worry about Brady, he's still loaded).
One banker told us: 'This can't be about the money. Dougan is a rich man, and can easily afford the $750,000. I guess he wants to make a point. But it could be quite an expensive one if he loses'.
