The HOA that I am a part of hires a property management company to handle our business. Our original contract was for 1 year, ending in 2006, but we have continued to do business with them currently through 2009. We have continuously paid them monthly and they have continuously provided their management services. Is the original contract agreement still valid? Or do we have to sign a new contract to have a valid business arrangement? Is the property management company still liable for their services under the original contract?
