Meaning
The verbal modification of a written contract occurs when the parties agree to alter their obligations without reducing the changes to writing. This transaction, termed an oral amendment, occurs in informal business interactions where speed is favored over administrative rigor. It governs the performance of service contracts, delivery schedules, and payment terms.
The boundary of this practice is often defined by the presence of a “no oral modification” clause in the original contract, which restricts the validity of non-written agreements.
Informal Modification
Operating under pressure often leads founders to adjust project scopes or timelines during phone calls or meetings. This verbal agreement, or oral amendment, can lead to disputes when the parties recall the terms differently. The absence of a written record means that the party asserting the change must rely on secondary evidence like subsequent conduct or email follow-ups.
In the event of a disagreement, proving the existence of the verbal agreement is difficult.
Evidentiary Challenge
Written records always carry more weight than recollections in a commercial dispute. A party seeking to enforce a verbal change must demonstrate that both sides acted in accordance with the new terms. This requirement makes an oral amendment difficult to sustain if one party resumes demanding performance under the original contract.
The cost of relying on memory rather than a signed document is measured in the time spent arguing over different recollections of the same conversation.
Preventative Clause
Modern contracts include provisions that invalidate any non-written modification. These provisions protect the written agreement from unauthorized changes. Having a clear process for written changes reduces the risk of litigation.
