What we cover in this guide 🤘

What is a loan agreement?

Loan agreements are legally binding agreements between a borrower and lender that explain the terms of a loan, including payment details, interest, late fees and more.

Sometimes these are also known as a promissory note. These agreements can be used to record the terms and conditions of a loan between your friends or family.

It’s a legally binding IOU, where a borrower makes a promise to repay the lender the principal amount (and any interest that is agreed).The agreement should include all the key elements below and be signed by all the parties involved to be legally binding. 

What needs to be in a loan agreement to make it official?

Does it need to be in writing? 

To be legally binding, yes, the loan agreement will not hold up in court if it's agreed verbally or with a handshake. It should be written and signed by the lender and borrower. This provides clarity to both the parties involved and displays the terms and conditions of the agreement. 

Should you add interest? What’s a fair rate?  

 The short answer is that it’s up to you. Some people may not want to charge their friends or family any interest on borrowed money, which is fine. Or you may consider charging some interest to ensure you’re not out of pocket due to inflation or if you’ve needed to take money out of your savings that were earning you interest elsewhere. 

While you can charge any interest amount you want, as it’s a loan to a friend or family member you might want to charge less than a bank would charge for a personal loan e.g. ‘mates rates’. This keeps things fair, and charging too high of an interest rate could void the contract (more on that later). 

It is also worth noting that charging interest on a loan would count as earnings and could affect how much tax you have to pay and require you to inform HMRC by submitting a tax return. 

Can a loan agreement be amended?  

Signing and dating a loan agreement or promissory note makes it official, but if both parties agree, changes can be made to the original contract. The best thing to do is to talk about it in advance and make arrangements that suit both parties. 

Why would changes need to be made?  

People may amend loan agreements for a variety of reasons. It may be to change the repayment dates, increase or reduce the interest charged or waive the remaining loan amount entirely. People's circumstances may change and you should consider whether you wish to accommodate changes to the agreement when you set it up. 

Could there be Tax implications?  

It’s a common misconception that because friend and family loans are a personal arrangement, there won’t be any tax implications. For loans without interest, you won’t need to tell HMRC.However, if there’s interest involved, you’ll need to inform HMRC and fill out a self-assessment as it may be liable as taxable income.

What can I do if a loan isn't paid back?  

When a friend or family member doesn’t live up to their end of the agreement things can start to become complicated. Failure to pay back personal loans can lead to awkward conversations and even a breakdown in relationships. 

Here are the steps you should take if it looks like the loan may not get paid back  2. Why should I use a loan agreement? You may trust the person you’re lending money to but having a loan agreement in place keeps the agreement crystal clear for both parties, sets exceptions and protects you in a range of situations.

This article takes a look at what constitutes a loan agreement and how to use one when lending your friends and family money.
