What's the risk of leaving qualifying language like 'material' undefined in the agreement?

The main risk isn't that the word becomes meaningless — it's that leaving it undefined shifts the real work of interpreting it from the negotiating table, where both sides have context and leverage to compromise, to a later dispute, where one side is trying to enforce a claim and the other is trying to avoid one, often with real money and a damaged relationship on the line. An undefined qualifying word like "material" invites each side to read it in whatever way suits its own position when a disagreement actually arises, and resolving that disagreement, whether through negotiation, mediation, or litigation, costs real time and money that a clearer definition could have avoided.

There's also a subtler risk: undefined qualifying language can make it harder to predict outcomes even for the lawyers advising each side, since reasonable people can genuinely disagree about where an undefined threshold sits, which makes settlement of a dispute harder to reach compared to a dispute over an objective, defined standard.

Leaving some genuinely flexible language in an agreement isn't always wrong, but doing it deliberately, and knowing exactly which clauses are gambling on later goodwill versus which need hard numbers, is a decision worth making with a Treadstone business lawyer rather than by default.
