On the other hand, an addendum adds a complete document to the existing document. An example of addendum used would be that the parties want to add something to the original document. For example, a person who buys a home might not buy all the furniture left behind. But after he kept thinking about it, he changed his mind. A supplement would then be designed to include the furniture he buys, and any additional charges for that furniture. For an addition to be considered valid, it must have mutual consent. When mutual consent is reached, this means that all conditions have been clearly communicated to the parties and are consistent with everything in the contract. If there are contractual elements that have not been discussed with the parties or if there is something that the parties cannot agree on, there is no mutual agreement. Another excellent example of endorsement is one that can be included in a contract to manufacture a particular product. The initial contract will likely include the company`s requirements in the manufacture of products in general for the company. However, the addendum can be further developed by specifying the products the company wants to manufacture and the specific parts and processes to be used in their production. Once an addition has been created, it must be signed as a separate document and assigned to the original document. An unsigned addition can be mistaken for a crude draft or, worse, something fraudulent that is attached at the last minute.

A signed addition confirms that its terms are legitimate, that the parties have accepted them and that they must be respected. An endorsement of a separation agreement includes, for example. B often, holiday visit plans that were not included in the original visit plan. The leave that is often omitted is those that are specific to a particular culture or religion, often because the lawyer who prepares the agreement knows nothing of the specific holidays that the family celebrates.
