Maxim 10.2.18
In the construction of contracts, words are interpreted against the person using them.
In stipulationibus cum quaeritur quid actum sit, verba contra stipulatorem interpretanda sunt.
Source: D. 45, 1, 38; Jackson; Weisman, 22r
Difficulty 2/5 — Approachable
Explanation
The drafter of a stipulation bears the risk of his own ambiguity; doubtful terms are construed against him who chose them.
Where this applies
- The company drafted the contract and now a vague clause is being read against me instead of them.
- Ambiguous contract terms should be interpreted against the party who wrote them.
- I didn't write this agreement — the unclear parts should be construed against the drafter.
