What characteristic is commonly associated with an addendum?

An addendum is typically defined as a supplemental part added to a document, especially contracts or agreements. Its purpose is to include additional information without altering the original content significantly. This can involve elaborating on certain clauses, clarifying terms, or providing new terms that complement the existing document.

The use of an addendum allows parties to maintain clarity and flexibility in their agreements, as it can address any new developments or changes that arise without the need to completely rewrite the original document. This characteristic of adding supplementary information is what distinguishes an addendum, making it a crucial tool for effective documentation in contractual relationships.
