Two major Florida law firms—Holland & Knight and Broad and Cassel—are targets of a $26 million malpractice lawsuit alleging they made serious errors in drafting a lease.

The lawsuit was filed Dec. 13 in Hillsborough Circuit Court by Miami attorney Warren Trazenfeld on behalf of Don Wallace, the former owner of what’s billed as the world’s largest recreational vehicle dealership, Lazy Days R.V. Center in Seffner.
