Rights and obligations of condominium association can be found in Florida Statue 718 as Lori mentioned (please refer to the link below). Moreover you should review By-Laws of a particular complex/subdivision and look for Assessments and Mannor of collection or other provisions that will refer to it. From my knowledge the Board of Directors should have a power to determine association fee increases and assessment charges (if any).
If I can help you in any other manner, please just give me a call 561.373.2401.
Have a great day, Lori
Another option to find the right person/department to handle your question, if its regulatory in nature is to contact your state representative and ask for assistance.
