Which of the following terms refers to the actual contents of a document?

The phrase "Within the Four Corners" refers to the principle that all information necessary for understanding the terms of a contract or document can be found within its four corners, meaning the text contained in the document itself. This principle emphasizes that the actual language and terms written in the document should be the sole consideration when interpreting its meaning, excluding any external evidence or outside communications.

The other terms have different implications. For instance, "Substance" refers to the essential elements or foundational aspects of the document, rather than denoting its specific textual contents. "Content" generally refers to the information contained within the document but is more broad and can imply different interpretations depending on context. "Context," on the other hand, deals with the circumstances surrounding the document's creation or the situation in which it's being interpreted, which can affect understanding but does not encompass the document's explicit contents themselves.

In conclusion, the term referring specifically to the actual contents of a document aligns closely with the concept of "Within the Four Corners," which stresses the importance of considering only what is written within the document for accurate interpretation.
