Expert writing Tips
Best practice
When using "required that", ensure the subject following "that" uses the base form of the verb (without 'to'). For example, "The law required that he submit the form" is correct, not "The law required that he submits the form."
Common error
Avoid using the past tense or present tense with '-s' after 'that' in a "required that" construction. The correct form is always the base form of the verb, like "required that she be present", not "required that she was present" or "required that she is present".
