Thank you for your question. I look forward to working with you to provide you the information you are seeking for educational purposes only.
The only way they can cancel the contract with you without your signature would be if you are breaching the contract (not doing something the contract says you must do). So, as long as you are abiding by the terms of the contract and you are paying what your contract states you must pay and what the bylaws of this Association say you must pay, then your contract cannot be cancelled.
However, you need to read that contract, not just what they told you, to see what they can and cannot charge you for, because what is written in the contract is what is binding and not their oral statements.
If they are claiming that you failed to honor the contract, then they can terminate the contract with you if they choose to do so I am afraid, it is called breach of contract. IF you did not breach the written contract, then you have grounds to sue them for illegally terminating your contract and you would have to take them to court to seek to recover your money if they refuse to return it.
I must give you also an opinion that we tell many people about these associations. If you are having issues with an association from the beginning, do not think it will get better over time, it will not, it will get worse. Associations with bullies on the board never get better and moving into them is a bad idea. If you have a chance out of the deal and to get your money from them do so and buy in a place where you do not have to deal with such people in an association. Under FL law, these associations are powerful and can cause you a ton of problems and headaches legally, so if this one is starting now like that, if you can get your money from them based on their breaching the contract, consider doing so and getting away from them.
