Condo/townhome litigation tends to very contentious and expensive. I tell most condo owners that it is best to pursue a political solution (lobby to overthrow the board) if they are not happy with the way things are run.
In your case, it seems like there is a serious concern about breach of fiduciary duty. Does your association carry Directors and Officers insurance? Does your association retain a lawyer for counsel?
If the money at issue is high enough, some lawyers will offer a mixed contingency/hourly fee, but few lawyers are willing to work on contingency only in these matters.
Though we strive to provide accurate legal information in our answers on AVVO, our answer should not be construed as legal advice and it does not create an attorney-client relationship. Our firm only forms attorney-client relationships by written agreement signed by both our firm and the client. Please seek an in-person consultation with an attorney immediately as almost all legal matters are time sensitive and failing to meet deadlines can result in adverse consequences.
Unless there are enough owners to side with you in voting out board members, my expectation is that you will need to pay to work with an attorney. Affording the cost would be much easier if several homeowners are sharing the cost. Any issues would be particularly important to address since the affairs of the association will be a concern to prospective purchasers in the future. A smart or well-represented buyer will not want to buy into a mess. There may be a way to later suggest that the fees should be paid through association funds, but an attorney will want to be paid without relying on that to occur.
The scope of this space does not afford an opportunity to adequately advise you. The response provided is intended to be informative, but not final. You are advised to arrange a consultation at which all facts and documents can be explored and terms for representation agreed. An attorney-client relationship must be formally established.
