The Most Dangerous Clause Is the One That Never Gets Written: Why power often resides in assumptions, not agreements

20 June 2026

Everyone negotiates the clauses.

Few negotiate the assumptions.

The shareholders’ agreement is signed. The articles are adopted. The governance structure is approved. Everyone leaves the room believing they understand how the company will operate.

And for a while, they do.

Then reality arrives.

One founder becomes more important than expected. An investor becomes less involved than anticipated. A director begins making decisions no one imagined would matter. A bank asks a question the documents never contemplated. A regulator interprets control differently than the parties intended.

The dispute that eventually emerges is rarely found in the agreement.

It is found in the assumptions that surrounded it.

Lawyers draft documents. Humans operate structures.

And humans fill gaps with expectations.

The most dangerous clause is therefore not the one that was poorly drafted.

It is the one that never gets written at all.

Every structure contains an invisible layer of assumptions: who will lead, who will defer, who will stay involved, who will remain aligned, who will act reasonably when circumstances change.

Most structures survive because those assumptions remain true. Most structures fail when they don’t. The lesson is simple.

When reviewing a structure, spend less time asking what the documents say. Spend more time asking what everyone assumes.

That is usually where the future dispute already lives.
