FL Commercial Property Manager Negligence?

[Susan Michael]

Surely there will be some "told you so" comments, however: family partnership owns commercial property in Florida and uses a property manager. Property manager (a small real estate company) resides in Florida only part of the year, making actual management difficult, but one-third of family partnership, an elderly gentleman, has been personal friends with the owners of the real estate company for 30+ years and is very reluctant to change. A new generation is now becoming aware of leases/repairs/etc. that are not correct. The new generation is the "general partner" but currently owns only 1% of the partnership. New generation of partnership does not know if there is a contract with property manager or if everything has been a "handshake deal" over the years, and the elderly gentleman offers no information. Is there any legal leg to stand on regarding the obvious flaws to this property and its management or do we just start from scratch and salvage what we can? Thanks for any information.
