问关于律师费用问题？

明尼苏达官司打了一年有余.

final trial 之前

1. 律师建议我不用出一分钱，律师建议给对方的协议也是这样的。
2. 律师告诉我，如果我有额外证据不能法庭当天才出，法庭当天出示的证据是不於采纳的。
3. 庭审已推迟两次，因对方不同意协商, 所以这次决心由法官评定

final trial 之中

无庭审，双方律师变协商。对方拿出8杆子打不着的证据（律师一直说有没有都和这案子没关系，但对我来说确是很隐私的事）要我签协议。我一直信任我的律师，就签了协议。

结果

这个协议我实际损失8万。我认为我的律师失职。

I was always told that a agreement is better settled if one thinks that it would be a better result than a trial. I was never told or even given a hint that this would be a better deal than a trial. This was always what the respondent asked for. The attorney offered 1000 discount, but it's very trivial considering the entire case caused me 20,000. I do not want to pay for the remaining 6000 because of the loss of the battle in such an unacceptable way.

Any professional input in this case is greatly appreciated. thanks
