Promissory notes and loan contracts: what they must contain and what you can enforce
By Equipo Prestafolio
The difference between a promissory note and a contract, the data neither can be missing, and which document actually helps you when the client stops paying.
The contract states what was agreed; the promissory note is the promise to pay that you can enforce. They are not the same thing and they do not replace each other: in most countries in the region a promissory note is a negotiable instrument that, if properly issued, opens the door to an abbreviated court process (commonly called summary or executory proceedings) whereas a plain loan contract usually forces an ordinary lawsuit, which is slower and more expensive. Lending with neither is not "trust": it is giving up on collecting in advance.
What each one is
Document | What it is | What it is for |
|---|---|---|
Loan contract | The full agreement: amount, rate, term, security, arrears, what happens on default | It defines the rules of the game |
Promissory note | An unconditional promise to pay a fixed sum | It is what you take to court to collect |
Disbursement receipt | Proof that the money was handed over | It closes the "they never gave it to me" gap |
The classic mistake is having only one. With a contract but no note, you have the rules but no easily enforceable instrument. With a note but no contract, you have an instrument… that does not say what rate was agreed or how arrears are calculated, and that is exactly where the debtor mounts their defence. You sign both, on the same day.
What a promissory note cannot be missing
The formal requirements are set by each country's law and you have to read it. We mean it: a note missing an essential requirement stops being a negotiable instrument and turns into just another piece of paper. That said, the elements almost every legal system shares are these:
Element | Why it matters |
|---|---|
The word "promissory note" in the text | Under many laws, without the wording the document is not a note |
Unconditional promise to pay | "I will pay", not "I undertake to try". A condition voids it |
A determined sum, in words and figures | If the amount is uncertain, it is not enforceable |
Name of the payee (who gets paid) | You, or your company, with its identification |
Date and place of issue | The time limits hang off it |
Maturity date | Without it, many laws treat it as payable on demand |
Debtor's name, ID document and signature | The signature is the document. No signature, nothing |
Always add, even where it is not mandatory: the interest rate, the arrears rate and the debtor's address. The address determines where and how they are served; a wrong address can cost you months.
What the contract cannot be missing
The contract is where everything the note cannot say lives:
- Full identification of the parties, with ID document and address.
- Amount handed over and how it was handed over (cash, transfer, cheque).
- Interest rate, with its periodicity, and whether it is on the balance or on the original amount. Write down the effective rate: see How much interest to charge for lending money.
- Term, number of instalments and frequency, with the amortisation table attached and signed. The attached table is what prevents the "that is not what I understood" argument.
- Arrears rate and grace days, with the formula. See How to calculate arrears on a loan.
- Acceleration clause: what happens if they miss N instalments. Without it, in principle you can only claim the overdue instalments, not the whole loan.
- Security or guarantors, if any, with the guarantor's signature.
- Right to prepay and how the balance is calculated if the client settles early.
- Place of service and jurisdiction.
- Signature of both parties on every page, and the date.
The evidence that is worth more than the paperwork
A perfect document loses to reasonable doubt if you cannot prove that that person signed it and that the money left your hands. Always attach:
Evidence | What it closes off |
|---|---|
Copy of the ID document, signed by the debtor | That they are who they say they are |
Fingerprint next to the signature | Very hard to deny afterwards |
Signed disbursement receipt, or the transfer confirmation | That the money really was handed over |
Identified witnesses who sign | They reinforce the authenticity of the signature |
Photos or video of the signing | Debatable as evidence, but they defuse most denials |
The disbursement receipt is the one most people forget and the one that decides most cases. "I signed, but they never gave me the money" is the most common defence there is, and if the disbursement was in cash with no receipt, it is your word against theirs.
Notary, witnesses and lawyer: when you need them
It depends on your country, and we are not going to invent a rule for you. The practical criterion is this:
- Small amounts, someone you know: a private document, signed, with a copy of the ID and a fingerprint. Usually enough.
- Amounts that would genuinely hurt: get it notarised. A signature certified before a notary instantly removes the argument about authenticity, which is where most cases collapse.
- With real security (a vehicle, a property): this is no longer a promissory note, it is a security interest that probably has to be recorded in a public registry to be effective against third parties. Without the registration, your "security" may be worth nothing if the asset is sold. Here you need a lawyer, no argument.
If the client stops paying
The order matters, and skipping it costs money:
- Documented collection efforts. Calls, visits, messages: dated and logged. This is not bureaucracy, it is the proof that you demanded payment.
- Formal demand for payment, in writing and with proof of receipt. In many jurisdictions this is what triggers default interest and enables acceleration.
- A payment agreement, if the client turns up. In writing. Have them acknowledge the debt: a signed acknowledgement usually restarts the limitation period in your favour.
- Court. This is where the promissory note earns its keep: with a properly issued instrument the process is shorter than suing on a plain contract.
Watch the clock. Collection actions expire, the limitation period for a note is different from that of an ordinary contract, and it differs in every country. A time-barred note is worth no more than the paper. Check the applicable period in your jurisdiction before letting a debt sleep "to see if they show up".
What you must not put in (even if they signed it)
An abusive clause does not protect you: it exposes you. In practice, if the judge strikes it out, it tends to drag the credibility of the rest of the document with it. The three you see most:
- Signing a blank promissory note, to "fill it in when needed". It is the fastest way to lose a case, and in several jurisdictions it carries criminal consequences.
- Interest above the legal cap. It does not make the loan more profitable: in many countries it voids the interest on the entire transaction (see the article on rates).
- Waiving the debtor's non-waivable rights. Signed or not, it is void, and it signals bad faith.
Summary
- Contract + promissory note + disbursement receipt. All three, the same day.
- The note is what you enforce; the contract is what explains the rules.
- Without signature, ID document and proof of delivery, you have nothing.
- The acceleration clause decides whether you claim one instalment or the whole loan.
- Limitation periods and formal requirements are set by your country's law. Read it.
Prestafolio generates the promissory note for each loan with the creditor's details, the debtor's details and the exact terms of the credit already filled in, with identified lawyer and witnesses, and files it alongside the client's record: see Generating a promissory note and Document library. The document is yours; what it saves you is writing it forty times.
