A more thorough explanation:

Definition: A NOM clause, short for "no-oral-modification clause," is a provision in a contract that states that the agreement cannot be changed or modified orally. Any changes to the contract must be made in writing and signed by all parties involved.

Example: A common example of a NOM clause is found in rental agreements. The clause may state that any changes to the lease, such as rent increases or modifications to the property, must be made in writing and signed by both the landlord and the tenant.

Explanation: The purpose of a NOM clause is to ensure that all parties involved in a contract are aware of any changes made to the agreement. By requiring written documentation and signatures, the clause helps to prevent misunderstandings and disputes that may arise from verbal agreements or changes. The example of a rental agreement illustrates how a NOM clause can be used to protect both the landlord and the tenant by ensuring that any changes to the lease are clearly documented and agreed upon by both parties.
