A notice clause should explain how formal notices under a contract must be sent and when they are treated as received.
Useful details include postal addresses, email addresses, delivery methods, attention lines, timing rules and whether notices can be served electronically. Notice clauses matter for termination, renewal, breach notices, claims and other formal contract steps.
Teams should keep notice details up to date, especially if a party changes address or contact person.
