Hi Marci I too have had a bad 2008 and have high hopes for 2009. The reason your lawyer is not looking up cases is because she know's she's not going to find any on point. these cases are governed by (1) the escrow agreement and it's express language, (2) whether he accepted the work in writing, and (3) the specific facts of each case. So there are probably not a lot of "reported" cases right on point.
IF THE ESCROW AGREEMENT IS HALFWAY DECENT you are only on the hook for the $6000.
Can he sue you for more? YES! Any jackass with the filing fee can sue anybody for anything in this country. THAT DOES NOT MEAN HE IS GOING TO WIN.
If you have a lawyer who is too busy to put you on her agenda, you need a better lawyer. I would not put up with that for one minute.
NO SCAMS here, you pay or not as you see fit. Good luck and good health in 2009.
