You have essentially two issues going on.  First, you have a bill to which theoretically none of the condo owners were privy.  If the contract was signed between two parties and you as current owners were not considered known third party beneficiaries when the contract was executed, you probably won't be liable for the bill and the homeowner's association should not pay. If it does pay, it should seek contribution (repayment) from the original entity or person who was supposed to pay the bill.  The person seeking payment may have a statute of limitations problems in that it may be too late to sue on that bill (each state only gives certain types of contract a certain amount of time to sue and they have to sue the right person to maintain jurisdiction).  Consider reviewing your association's bylaws and any documents filed with the state registry of deeds to see if this pops up or at least is mentioned or can be construed to fit within specific provisions.
