Midland firms have been placed on red alert amid fears corporate websites could be falling foul of internet laws.
Large numbers of sites for businesses may be in contravention of the rule book governing the information super-highway, according to Birmingham law firm The Wilkes Partnership.
Julia Lowe, a commercial dispute resolution partner at Wilkes, has warned businesses to keep in touch with the latest legal developments.
She said: "Businesses need to remain aware of all the regulations and keep up to speed with the ever-changing legal environment for e-commerce.
"If your business sells goods or services on your website you need to comply with Distance Selling Regulations.
"Also, if people send you personal information, such as registering an interest in products, you need to meet data protection laws.
"All websites are also a form of advertisement so they need to comply with various advertising rules."
The advice was issued following a case in which Virgin Wine Online was forced to revise its terms and conditions following an intervention by the Office of Fair Trading.
She added: "The OFT had a number of concerns regarding delivery and cancellation rights, and terms that limited Virgin Wine Online's liability. "They had to make changes under Distance Selling and also unfair terms legislation.
"The OFT is very keen to protect consumer interests with internet activity, and companies need to be aware of the different acts that have now become law."
