Verba chartarum fortius accipiuntur contra proferentem

It is a Latin legal maxim that translates to “Words in a document are taken more strongly against the one who produces them.”

This principle is frequently applied in legal contexts, particularly in contract law. It implies that if there is any ambiguity or uncertainty in the language of a contract or legal document, the interpretation that is less favorable to the party who drafted the document will be favored. In other words, this principle places the responsibility of clarity on the party who created the document rather than on the party who did not have a hand in its drafting.
