Whether in your standard terms or in a negotiated contract, in a commercial contract a clause providing the parties with a mechanism for varying the contract is essential.
However, a recent High Court case, Virulite LLC v Virulite Distribution Ltd  EWHC 366, made it clear that even where the contract specifies that variation must be agreed in writing, this ain’t necessarily so…
Hidden in the “boilerplate” terms at the end of the contract the variation clause is often overlooked during the initial negotiation of a contract. The variation clause that our commercial contract lawyers most commonly draft is one which requires any variation to be made in writing (and often signed by both parties).
Virulite underlines the importance of being very clear if you are intending to vary a contractual term. It should be a health warning for anyone entering into contracts because even if your contract states that any variation to the contract must be agreed in writing, there are still occasions when an oral agreement can vary the terms of the contract.
The facts included several key factors which led to the Judge deciding that an oral variation to the contract was effective. Those factors were:
In addition to the specific facts of this case, the Judge emphasised three points to consider when you are re-negotiating contractual clauses:
1) if the variation clause was specifically negotiated by parties, in general, this would point to the contractual variation clause being binding.
2) a contractual variation clause expressly requiring variation to be in writing was not absolute.
3) was the outcome of the oral negotiation of the variation intended to be legally binding on the parties.
It will not be easy to show that an agreement was varied by oral agreement, contra an existing term of a written contract. If you are the party who is arguing for the amendment, the burden of proof will be on you to show that there has been an effective variation. However, this case shows that it can happen.
