Sub-contractor contract still standing after Company Sold ??

I  am a lawyer in CT and practice in this area of the law.  Your hypo is hard to follow.  As i understand it, you contracted with a company that subsequently got bought by another company.  The contract that you have likely has a clause that says that the contract is binding on company B's successors, and assigns.  This means that if company C took over company B, company C is obligated to honor the contract and stands in company B's shoes.  If company C only acquired certain assets of Company B and Company B is still operating, then Company C is not obligated to the contract.  i suggest bringing the contract to a lawyer to determine Company C's obligations to your company.  most lawyers will give you a free initial consultation to determine whether you have a valid basis to file a suit to enforce your contract.
