“No Oral Modification” – does it mean what it says?

“Boilerplate clauses” are a standard part of most written contracts and are rarely given much thought.  They provide the basic provisions which are considered appropriate in nearly all contracts.  A common one provides that any variation to the agreement must be in writing and signed by or on behalf of the parties.  This is known as a “No Oral Modification” clause, or “NOM”.  Its purpose is to reduce the potential for future disputes where one party seeks to argue that the other had orally agreed to their departing in some way from the terms of the written contract.  This helps create certainty (which is the point of putting contracts in writing), but the problem is that in practice the parties don’t read their contracts (and especially not the boilerplate clauses, which are considered “legalese”) and so do sometimes actually agree such oral variations, which they then proceed to act upon.

Take this example:

“All variations to this Licence must be agreed, set out in writing and signed on behalf of both parties before they take effect.”

This wording was in a licence to occupy serviced offices in central London granted by MWB Business Exchange Centres Ltd to Rock Advertising Ltd.  Rock fell into arrears and claimed to have agreed a revised payment schedule over the phone with MWB’s credit controller.  The credit controller’s boss didn’t approve the proposed payment schedule, and MWB evicted Rock and claimed the arrears.  Rock counterclaimed for wrongful eviction.  The judge found there was indeed an oral agreement to vary the licence, which the credit controller had authority to conclude, but it was ineffective as it didn’t comply with the NOM.

The case went all the way up to the Supreme Court, as there was no clear authority under English law whether NOM clauses were effective.  The general view, supported by recent cases (and by the Court of Appeal in this case), was that they were not – because the parties had freedom to contract orally and so could agree a subsequent oral contract which would impliedly override the NOM.  But lawyers still included NOMs in contracts – just in case they did work.

The Supreme Court, in Rock Advertising Ltd v MWB Business Exchange Centres Ltd [2018] UKSC 24, held 4 to 1 that NOM clauses did indeed work (so we lawyers were right to include them all along).  Lord Sumption, delivering the lead judgment, explained his view that:

“What the parties to such a clause have agreed is not that oral variations are forbidden, but that they will be invalid. The mere fact of agreeing to an oral variation is not therefore a contravention of the clause. It is simply the situation to which the clause applies. It is not difficult to record a variation in writing, except perhaps in cases where the variation is so complex that no sensible businessman would do anything else. The natural inference from the parties’ failure to observe the formal requirements of a No Oral Modification clause is not that they intended to dispense with it but that they overlooked it. If, on the other hand, they had it in mind, then they were courting invalidity with their eyes open.”

Lord Briggs disagreed with this analysis, but agreed the appeal should be allowed.  He took the view it was theoretically possible to agree orally to dispense with a NOM clause, but the Courts would only imply that the parties had done so where “strictly necessary”, rather than as a matter of course just because they had not complied with the NOM.  He therefore agreed with the majority that the oral variation was ineffective in this case.

So we now have clear authority that NOMs work, and that you can’t agree to delete them except in writing.  This is good for legal certainty, but is likely to create problems in those cases where the parties have agreed an oral variation anyway and gone ahead and acted upon it.

In such cases, as Lord Sumption pointed out, “the safeguard against injustice lies in the various doctrines of estoppel”; i.e. if something is agreed orally and one party acts in reliance on it to their detriment, the party who allowed this to happen will be “estopped” from relying on the NOM.  You might think this is the same thing as allowing oral variation of NOMs, but the subtle legal difference is that estoppel is an equitable doctrine which allows the Courts to do justice in individual cases rather than a hard and fast rule that a party can always rely on.  So the contract remains as per the written terms, but that doesn’t mean you’ll be able to enforce it if you’ve allowed the other party to believe you agreed you wouldn’t.
