The buyer and the seller are able to terminate the contract of sale after the attorney review period if certain contingencies are not met. For example, if the inspection reveals defects and the seller is unwilling to repair and the buyer is unwilling to buy without the repairs, then the buyer or the seller may terminate the contract. With the mortgage contingency if the buyer is unable to gain approval for a mortgage then the buyer may cancel the contract. There may be other contingencies in your contract that will depend on the language contained in your contract and attorney review rider. In short there may be ways to terminate the contract of sale after the conclusion of attorney review.
