In a real estate loan, which document provides the evidence of the debt and is the primary instrument?

• A. Deed
• B. Trust deed
• C. Promissory note
• D. Mortgage

Answer: (C)

The key idea is that the debt itself is created and evidenced by the promissory note. It’s the borrower's promise to repay, stating the loan amount, interest, payment schedule, and due date—forming the personal obligation to pay back the money. The note is the primary contract between borrower and lender.

The security instrument—whether a mortgage or deed of trust—serves to encumber the property to secure that debt. It gives the lender a lien and a remedy if payments stop, but it does not by itself create the debt or the obligation to repay. A deed, on the other hand, transfers title and is not the debt instrument.

So the promissory note is the document that evidences the debt and stands as the primary instrument.
