In construing the release, the courts frequently repeat the general formula that the intention of the parties as determined by the ordinary rules of construction, is to be ascertained, and when ascertained, it is to control.1 Provisions of a release "are not to be shorn of their efficiency by any narrow, technical and close construetion."2 As will be seen later,3 the repetition of this formula does not prevent the courts from ignoring the intention of the parties when they attempt to grant a release to one of two joint debtors, reserving intact the rights of the creditor against the other joint debtor..

The release is to be construed as a whole.4 The words of the release are not to be extended as against the releasor.5 If a dispute has arisen with reference to the amount of commission for selling certain property, a release in consideration of a certain sum, which provides that the broker has "no claim whatsoever," is to be construed as applying only to his claim for commissions for the sale of such property, and it does not operate as a release of a claim of commissions for the sale of other property.6 A release of claims for work done under a contract, is not to be extended to a claim for damages for the breach of the contract.7 The words of a release are to be limited by the express consideration mentioned for such release.8
