在条件解除日前，买方可以通过经纪以书面形式（release for sale或者addendum)告知卖方合同不继续履行。另外，一般买卖合同会有这样一个条款：
The above subject clauses are for the sole benefit of the Buyer and may be waived unilaterally by the Buyer in order to proceed with completion of the contract. Should these subject clauses not be removed from this contract by notice in writing to the Seller or the Seller's Agent by mm/dd/yyyy, this contract shall be null and void. 这个条款就是明确买方不继续履行合同的权利的。
