"Decisions are made by those who show up".
Having once lived in a condo community and worked on a condo board as well as having been board president for many years, I can tell you that it is a thankless time consuming job that very few people appreciate. Yet I did it for 13 years and found it to be a great learning experience.
That being said, your community has to come together in order to protect it's investment.
I would recommend getting together with the remaining board members and anyone else who is interested in joining and meeting informally (over coffee at your house for example) to develop a strategy. You need to communicate what is happening to the rest of the community - door to door if you must - to drum up interest.
You might even want to gather people together at fun informal events to build community spirit which sounds like yours is lacking of late. Folks are more likely to show up at a block party on the weekend vs. a meeting late at night after work when most are too tired or need to get the kids down to sleep on a school night. Once people can put a face to the name and get to know each other, most will now interact more comfortably and be able to discuss issues without yelling. Building trust is key.
The advice below is very sound and I agree that at some point it may make sense to speak with an attorney.
However, this depends on whether or not your condo has an attorney and how that attorney has been instructed to handle board communication.
We had a wonderful attorney, but it was expensive to use him. We found that we had to be careful in utilizing his time because the bill was being paid by the association. If you had a board member who spent a lot of time on the phone with the lawyer, the bill was very large as he was paid by the minute. We had to be very careful and choose one or two points of contact and be very specific about what to discuss.
It may be that the boards attorney may not be allowed to speak with community members only because he or she needs to be paid somehow and it may not be considered authorized use in order for the lawyer to send a bill.
So my advice is to read the by-laws as stated below, but really focus on team building and community building first. Figure out first what it is you want to accomplish as a group, then call the lawyer if you need to. (Unless of course you are willing to pay for one yourself which may not accomplish much anyway.)
Again, good luck!
Definately read that HOA CC&R's and see if there is a provision for replacement of the board. As far as the Property management is concerned, a lawyer will stir them up if you are paying for services not rendered. Good luck.
This can be fixed but the way you described the situation you need to get involved and protect your own investment.
