Advertising and Marketing Law

Advertising campaigns are one of the most common areas in which businesses might run into legal trouble. There are rules governing the claims businesses can make about a product’s efficacy and how they must be able to prove those claims, nuances about what types of products can be advertised and in what way, and even guidelines on how to avoid certain stereotypes when depicting people in ads.

e.g. London

How do these lawyers work?

These lawyers help to ensure advertising campaigns comply with the law, whether it is for print, broadcast, or the internet. They ensure that marketing and advertisements comply with guidance set by regulators such as the Advertising Standards Authority (ASA), Ofcom, and the Information Commissioner’s Office (ICO) so that businesses can run a campaign without worrying about fines or ads being taken down.
