There's no escaping the law just because you're trading on the Internet. If anything you need to be more cautious and really understand the rules of contract law so that you don't make expensive mistakes. Many people have no idea when a contract is actually made. Trouble can come fast on the web when we are (on the face of it) selling to anyone in the world.

A contract is generally made when someone agrees to do something for someone else for a fee. The fee is called the "Consideration". The problems arise over "offer and acceptance". If you say to someone "I offer to do x for you" and they say "I accept" then subject to the fact there was an intention to make a contract) that is a contract. Is the world that simple? We all know it isn't! Often, of course, someone will reply, "I'll accept if you do z as well", that is not an "acceptance", that is a counter-offer. This is crucially important, because until an offer has been accepted, but there is no contract and as such either party can get out of the deal. Also, when a contract is made normally you cannot change the details of it without the agreement of the other, so if you want to put in a disclaimer or other protection for yourself it MUST get in before any offer is accepted.

One case many years back dealt with an important point on when is an offer an offer. A man put a flick-knife on display in his window with a price tag on it. Was that an offer? You might be surprised to hear the Court decided not. It was merely an invitation to people to offer to buy it. This is a most important case for the web. It means that merely having something on your site is not an offer. The person who then says they want to buy it is actually making the offer. Until you accept their offer you can withdraw from the proposed deal and/or add small print in. This gives you an opportunity to check you haven't gone wrong.

In a famous case retailer, Argos didn't have a failsafe to check their web contracts were commercially sensible.

Argos posted details on their website for televisions. Instead of a price of £399 per item they were shown at £3.99 on the website. This constituted an offer to buy, so you might think they were OK because, like the flick-knife case, until they accepted a purchaser's credit card details no contract had been made. Unfortunately, with the wonders of modern technology such a contract was made. People clicked to buy, they sent credit card details and of course, to the computer, it all looked good: "1000 units x £3.99 = £3990 and that is what they've paid" so it sent a confirmation, which constituted an acceptance of the buyers offer and created a contract. When Argos later realised their mistake, it was too late.

A cautionary tale, the lessons are simple - check very carefully the information you put on your website and build in some manual checks to any automated process to make sure errors can be spotted and rectified quickly.

It's essential that your website contains the right small print or terms and conditions for your on-line business.

There are 3 main types of small print-nicked ones, "lawyer's beauties" and informal. So, what sort of small print should you have?

The web is informal and there is a clear resistance to complex small print. That said, there is no point in small print which is wrong or inadequate or, as is sometimes the case, illegal.

Many people copy their off-line small print, if they have any. This is often dangerous. It does not cater for various things such as a Returns Policy and the nature of the web.

Some use "nicked" ones, in other words those copied from other sites. This can be dangerous from a few angles. How can you be sure they are suitable? The site they were taken from might have taken them and so on. And if lawyers have drawn them up they often put in a deliberate mistake to enable them to identify them and you will be liable for major damages if you're found copying them.

Then there are those that we will call "lawyer's beauties". A lawyer will have spent many days, and many of your £s, making sure every possible angle is covered and you will end up with pages and pages of long words, which neither you nor your customers will understand. But you will be well protected. It is a commercial choice for you. But to be honest the Woolley & Co view is that if you feel you need small print like this you are probably so averse to risk that you "shouldn't use the M1", let alone trade on the Internet.

Woolley & Co draft plain English small print that works well on the web, and is more popular with customers, who prefer small print they can understand.

We've got small print that protects us against unreasonable claims, now how do we make sure it "sticks" on the other party?

We MUST make sure it is in the paperwork BEFORE the contract is made. It is therefore often best to put it in right at the start. But how do we prove, on the web, that the other person has seen it?

It is thought to be best to have a button whereby people have to click on Yes to the question "Have you read, understood and agree our terms and conditions" with a scrolling page containing them. They should not be allowed to go on with an order until they have said "Yes".

This article only "scratches the surface" of a complex subject. Every business and site is different and it's important that you have terms and conditions that are right for your business and written to fit in with the design of your site.
