Thank you. First of all, you make an assumption that most attorneys will agree to take a flat fee for a defense of a civil case. This is not true. Most defense attorneys (civil) charge hourly, between $150 to $250 or more per hour. They work off a retainer of anywhere of $5,000 and up.
At $25,000, that flat fee is a little high but may be justified if the lawsuit is large, and/or, if the attorney expects to spend as much time so as to justify the $25,000 if he were billing hourly at a reasonable rate.
If you mean that the $25,000 is a retainer, then understand that the attorney would actually, actively be billing against it. Then, that retainer is not unusual for a big company, but of course this is with the presumption that the attorney's hourly rate is reasonable.

Kindly rate my answer as one of TOP THREE FACES/STARS and then SUBMIT, as this is how experts get credit for our time. Rating my answer the bottom two faces/stars (or failing to submit the rating) does not give me credit and reflects poorly on me, even if my answer is correct. I work very hard to formulate an informative and honest answer for you; please reciprocate my good faith with a positive rating.
