If your lawyer or accountant made an error when a case of your was closed and they refunded you what they thought was the balance in your trust account - $500, calling it a final statement/account closed...A month later, they realized that there was $1,500 in your account and your $1,000 was still sitting there - it's YOUR money. You would want that money back, right? They would be "obligated" to send it to you. Why do you think you don't owe what you DO owe, just because their calculations were off? Obviously, you have never had any education in accounting or legal figures. There is something called "errors & omissions excepted", E&OE. It means they have the right to fix an error in the figures. You owe the money. Even IF there was a legal loophole that meant that you did not have to pay it, which there is not, part of being an "ethical" and "moral" human being is paying your due fees and costs and not trying to rip off someone over a typo or a miscalculation. Shame on you. I mean really!!!
