The Latin phrase “mala grammatica non vitiat chartam” can be translated to “bad grammar does not invalidate the document” in English. This phrase implies that grammatical errors or mistakes in language usage do not make the content or legal significance of a document null and void. In other words, even if there are grammatical errors in a written document, the content and its legal implications remain valid. This concept is often used in legal contexts to stress the importance of the content and intent of a document over minor linguistic errors.
