Other names in this document: contract renewal letter, contract renewal agreement Before you sit down to write, you decide exactly what your renewal goals are. Try to enter revisions without invalidating or confusing the original agreement. Does enlargement have a defined term? Will it last indefinitely? Are there any other treaty changes that need to be made? Enlighten these terms before writing them. Both parties should carefully review the extension to ensure that all relevant points of the agreement have been included. It is better to be excessively inclusive than sub-inclusive. Do not assume that certain expectations or conditions are agreed upon if they are not expressly stated on the document. It may be mentioned that the extension agreement, together with the initial agreement attached, constitutes the entire agreement between the parties. . . .
