- Maker
- The party who signs the promissory note and promises to repay the loan — also called the borrower or obligor.
- Payee
- The party to whom the loan is owed and to whom repayment must be made — also called the lender or holder.
- Principal
- The original sum of money lent, before interest or fees are added.
- Acknowledgment
- A formal declaration, typically made before a notary public, confirming that the signer executed the document voluntarily and is who they claim to be.
- Acceleration Clause
- A provision that makes the entire remaining loan balance immediately due and payable upon a triggering event, such as a missed payment or breach of terms.
- Default
- Failure by the maker to meet any obligation under the note — most commonly missing a scheduled payment — which triggers the lender's remedies.
- Usury
- Charging an interest rate that exceeds the maximum rate permitted by law in the applicable jurisdiction — making the excess interest unenforceable or the note voidable.
- Amortization
- The process of spreading loan repayment across equal periodic payments that cover both principal and interest, so the balance reaches zero at maturity.
- Notary Public
- A state- or government-commissioned official authorized to witness signatures, administer oaths, and certify that a document was signed voluntarily by the identified parties.
- Recourse
- The lender's legal right to pursue the borrower's personal or business assets beyond the collateral in the event of default — as opposed to a non-recourse note where recovery is limited to the pledged collateral.
- Holder in Due Course
- A party who acquires a negotiable promissory note in good faith, for value, and without notice of defects — generally taking the note free of most defenses the maker could raise against the original payee.
