They can be a chore to set up, though, and it's tough to know exactly how to set them up. Here, at least, is a cautionary tale showing that there are some types of fee agreements you definitely should not enter into.
Tipler represented an 18 year-old mother on charges of aggravated assault and charged a flat fee of $2300. As part of the fee arrangement, Tipler agreed to reduce the balance by $200 every time the client had sex with him, or by $400 every time the client arranged for another woman to have sex with him, according to an opinion by the Florida Supreme Court.
Tipler and the client had sex, and the client arranged trysts with another woman. As a result, Tipler ended up pleading guilty to solicitation of prostitution. The Florida Supreme Court also disbarred him, but not just for the fee agreement. The court found that Tipler:
". . . altered evidence and caused a witness to unknowingly give false testimony. He has charged his clients excessive fees and stolen their money. He has failed to maintain a trust account," wrote Chief Justice Peggy Quince.
"He has broken public confidence in the profession of the practice of law by neglecting his clients and failing to prosecute their cases. He has prejudiced the administration of justice by misrepresenting facts to multiple courts. And, through the disciplinary process in these cases, he has been dilatory, deceitful and evasive."
Don't be a Tipler.
