Statutory text
Bare law
A “bill of exchange” is an instrument in writing containing an unconditional order, signed by the maker, directing a certain person to pay a certain sum of money only to, or to the order of, a certain person or to the bearer of the instrument.
A promise or order to pay is not “conditional”, within the meaning of this section and section 4, by reason of the time for payment of the amount or any instalment thereof being expressed to be on the lapse of a certain period after the occurrence of a specified event which, according to the ordinary expectation of mankind, is certain to happen, although the time of its happening may be uncertain.
The sum payable may be “certain”, within the meaning of this section and section 4, although it includes future interest or is payable at an indicated rate of exchange, or is according to the course of exchange, and although the instrument provides that, on default of payment of an instalment, the balance unpaid shall become due.
The person to whom it is clear that the direction is given or that payment is to be made may be a “certain person”, within the meaning of this section and section 4, although he is mis-named or designated by description only.
Key rule and applicability
A bill is a written, signed, unconditional order directing a certain person to pay a certain sum of money only to the stated recipient or bearer. The additional paragraphs address a certain event with uncertain timing, future interest or exchange calculations, instalment acceleration and identification despite a misnomer or description.
Limits and related provisions
A bill’s order is different from a promissory note’s undertaking. Do not assume every invoice or conditional commercial instruction is a bill. The certainty explanations preserve specific forms; they do not validate an obligation dependent on any uncertain event or a demand for money plus non-money performance.
Hypothetical business example
Hypothetical: a signed payment order includes future interest and acceleration of the unpaid balance after an instalment default. The business checks the section’s certainty explanation and every other definition element instead of rejecting the instrument merely because those terms appear.
Practical decision flow
Check writing, signature, unconditional order and the identified payer.
Examine the money-only amount and the payee or bearer direction.
Apply the specific certainty explanations to timing, interest, exchange and identification terms.

Frequently asked questions
Is a promise the same as the order required for a bill?
The statutory definitions distinguish a bill’s order from a note’s undertaking.
Does future interest necessarily make the sum uncertain?
No. The section expressly addresses certainty despite future interest.
Does a misnamed recipient always defeat certainty?
The text permits a person to be certain where it is clear who is intended despite a misnomer or description.
