For example, Florida Bar Rule 4-1.5(a) prohibits "clearly excessive" attorney's fees, while 4-1.5(f)(4)(B) sets several criteria for contingency fees (typically the sort of fees a plaintiff's firm would charge) that, if not met, renders a fee presumptively "clearly excessive".

Most Florida contingency fees will be about 1/3 of collectible settlement/awards.

...after expenses which can be considerable.

Presumably talking about damages.
