What a note records
A note commonly identifies the maker, payee, principal, payment timing, applicable interest, and signature. It may address installments, maturity, and default. Required formalities and permitted charges depend on applicable law.
A note can be part of a larger lending arrangement containing separate covenants or security documents.
Negotiability is a separate question
Under U.S. state enactments of UCC Article 3, negotiable instruments must meet specific requirements. Calling a document a promissory note does not automatically make it negotiable.
A document outside Article 3 may still create contractual rights. Conversely, a signature alone does not resolve every issue of validity, defenses, or who is entitled to enforce it.
A note does not automatically pledge assets
Hypothetical example: A borrower signs a $10,000 repayment note. Unless the transaction also establishes valid security rights, the note does not by itself give the lender a lien over the borrower's vehicle.
Collection review
Verify the payment history, remaining amount, amendments, ownership or enforcement authority, limitation periods, and applicable notices. Retain supporting records.
A note does not remove the need to establish a claim or follow lawful enforcement procedures. Garnishment, foreclosure, and asset seizure require their own legal basis and process.
