This note explains the principal legal distinctions between promissory notes and bills of exchange under the law of England and Wales. It is prepared for an international corporate audience from our London office at Holborn Gate, 330 High Holborn, London, WC1V 7QH, England.

Definitions and parties

Both instruments are negotiable instruments in form: written documents that create or evidence an obligation to pay money. The essential differences are structural and procedural.

• Promissory note: a written promise by one party (the maker) to pay a defined sum to another party (the payee) or to bearer. It is essentially a two‑party instrument: maker and payee.
• Bill of exchange: a written order from one party (the drawer) directing another (the drawee) to pay a sum to a payee. It typically involves three parties: drawer, drawee and payee. A cheque is a common form of bill of exchange drawn on a bank and payable on demand.

Negotiability, acceptance and liability

Promissory notes and bills of exchange are transferrable by endorsement and delivery, subject to the formalities set out in statute and case law. Key practical distinctions include:

• Acceptance: A bill of exchange generally requires acceptance by the drawee to bind the drawee as a primary obligor. A promissory note does not require acceptance — the maker is immediately liable.
• Primary and secondary liability: The maker of a promissory note is the primary party liable. For a bill of exchange, the acceptor (when acceptance is given) becomes the primary obligor; the drawer and endorsers have contingent or secondary liability.
• Form and maturity: Both instruments may be payable on demand or at a fixed/detachable future date. The wording should clearly specify amount, payee, date/place for payment and signature(s).
• Dishonour and remedies: provisions dealing with presentment, dishonour, notice and protest differ in practice and can be important in cross‑border transactions; timely action is required to preserve rights against endorsers and drawer/acceptor.

Practical use and risk management

Choice of instrument will reflect commercial objectives and risk allocation:

• Use promissory notes where a direct, contractual promise from borrower to lender is preferred (domestic financing, short‑term loans).
• Use bills of exchange where an ordered payment mechanism is helpful in trade or where presentment and acceptance procedures are part of documentary collection arrangements.
• In international transactions consider governing law, jurisdiction clauses, currency, required endorsements, and the impact of local laws where enforcement may be required.
• Cheques remain a special category and carry additional practical banking rules.

Practical checklist before issuing or taking an instrument

• Confirm the correct instrument type for the transaction and the parties’ intended allocation of liability.
• Check that wording names payee, amount (currency), due date or demand terms, place of payment and contains a valid signature.
• Consider endorsement language and whether transferability to bearer is intended.
• Agree governing law and jurisdiction for disputes and consider inclusion of security or guarantees where appropriate.
• Plan for presentment, acceptance (for bills), and procedures on dishonour including notice requirements.

Jurisdiction and sources

Key primary sources and practical guidance for England and Wales include:

• Bills of Exchange Act 1882 (legislation.gov.uk)
• legislation.gov.uk (statutes and statutory instruments)
• GOV.UK (practical guidance on debt enforcement and courts)
• HM Courts & Tribunals Service (enforcement and procedural information)

When cross‑border enforcement or local practice matters, consult the applicable foreign law and local court practice in the relevant jurisdiction.
