promissory note
A promissory note is a written, signed promise to pay a set amount of money, either on demand or by an agreed date.
In plain English
A promissory note gently turns a spoken promise into something that stands on its own two feet. It names who owes, who is owed, how much, when it is due, any interest, and it carries the borrower signature.
That signature is the whole difference between lending on a handshake and lending with a note, because if the money is not paid, the note is evidence a court will actually recognise. You meet these more often than you might guess.
A friend borrows a large sum and writes a simple note with the terms. A supplier lets a business pay in 60 days against one.
Companies and governments issue grand, formal versions to raise serious money. The beauty of a note is that it makes the terms plain and hard to argue about later, which protects both sides equally.
And here is the part worth saying warmly. When you lend a meaningful amount, even to family, a short written note is not a sign that you do not trust them.
It is a real kindness, because it helps prevent the painful, memory against memory arguments that can crack a good relationship. Keep it simple, state the amount, the date, and any interest in clear words, and both of you sign with a smile.
A friend borrows ₦400,000 and signs a note agreeing to repay ₦400,000 by 31 December, with no interest. If memories ever differ down the line, that signed note settles it and keeps the friendship whole.
Questions people ask
Is it legally binding?
Yes, when it is properly written and signed, it is a recognised promise to pay.
Does it need interest?
No, it can be completely free of interest. If interest does apply, just state the rate plainly.
Should I really use one with family?
For large sums, yes. Clear terms today prevent the disputes that damage relationships tomorrow.
