What is the maximum contingency fee in a medical malpractice case?

In Texas medical malpractice cases run on a contingency of 45-50%. If you hear numbers from out of state lawyers.... Keep in mind that those states probably don't cap pain suffering etc to 250k. Additionally, if this is a wrongful death you are capped at 500k.

Contingency fees vary by attorney. For example, my top-rated firm in PA & NJ only deducts a 29% fee. You can search lawyer profiles in your state for a top-rated firm with a reasonable fee.

You would be smart to get a good local lawyer with a low contingency fee

I have seen lawyers charge any where from 25%-50%. Most attorneys work on contingency fees of 33% to 40%. If the case is not referred by another attorney, I usually will reduce my fees, especially when it involves a minor, or birth injury case. Some States have caps on attorney fees. In Illinois in malpractice cases it is on a sliding scale. In TN fees are capped at 33%. You need to hire whomever you feel comfortable with, and see if they will work with you on the fee agreement.
