Why is this so important? Because the correct signature on behalf of a company prevents the person signing the contract from personally fulfilling the company`s contractual obligations. If an entity is a party to a contract, it is essential that the signature block correctly identifies the party signing on behalf of that entity. For example, if someone signs as the president of a company, the signature block should look like this: the importance of it cannot be emphasized enough. Obviously, you don`t want a company to say that they don`t have to abide by the contract because it was signed by someone who wasn`t allowed to do so. Therefore, if the other party is a corporation, you need to be sure that the corporation does exist, that the person signing on behalf of the corporation has the authority to do so, and that the contract has been approved by the shareholders or directors of the corporation. Whether you sign the contract correctly can mean the difference between a smooth business transaction or a chaotic legal dispute. The parties are not obliged to sign the same copy of the contract for it to be mandatory. When the parties sign different copies of the contract, they must agree that each of their signature pages constitutes a complete agreement executed. For this reason, contracts often contain a provision stating that “the parties may perform this contract in consideration, each of which is considered original and all of which form a single agreement”. If the treaty has been the subject of a series of rounds of negotiations or revisions, do not just consider that the copy that will be submitted to you for signature is what you think. Before signing it, absolutely make sure you know and understand the terms of the document.
