I act for both buyers and sellers of technology products and services. Since establishing Clayden Law I have established a nationally recognised expertise in cloud services, in particular “software-as-a-service” (SaaS) agreements and reseller agreements.


Piers founded ClaydenLaw in 2010. Prior to that he was a partner at Manches LLP (now Penningtons), having trained and qualified as a solicitor with DLA Piper in the City.

During the course of his career, Piers has been on secondment in-house with large multinational companies such as Taylor Woodrow, Hasbro, Granada TV (now ITV) and Vodafone.

Piers is a regular speaker at public seminars and training courses and is an active member of the Society for Computers and Law.

Family life seems to hoover up what is left of time outside the office, but every now and then Piers does a spot of swimming, cycling and running (AKA triathlon) and he is an avid supporter of Wasps Rugby Club and England Rugby.



Piers is ranked in both the Chambers & Partners and Legal 500 directories, Thames Valley, for his expertise in Information Technology. Clayden Law and Piers are reported as:


Piers Clayden is well versed in the negotiation of various types of IT contracts including master service agreements, reseller agreements and software development contracts. “I have worked with Piers Clayden through complex client negotiations in which he has always taken a calm approach that gets the right results.””He is very good at seeing the bigger picture and drafting a contract to include clauses others hadn’t thought of.”

Piers Clayden of Clayden Law is well versed in the negotiation of various types of IT contracts including master service agreements, reseller agreements and software development contracts.

“Piers is an excellent solicitor.”

“Piers is expert and personable – a lawyer that establishes instant and well-deserved trust.”

“Piers Clayden is excellent – he is responsive and always tries to accommodate our requirements and timelines. He also takes a pragmatic view, understanding our commercial drivers.”



Strengths are domain specialisation (knowledge), accessibility of resource, flexibility in approach, right-size delivery, calm and unfazed commercial negotiation style. Being a small team it doesn’t feel like you are paying for multiple resources when they are not all needed which can be an issue with other companies.

“Piers and his team have consistently provided quality, right-size advice and their expertise in Technology, SaaS and data privacy have been pivotal to us. I have also worked with Piers through complex client negotiations through which he has always provided a calm approach that gets the right results.”

“Clayden Law is a practice focused on Information technology, data privacy and cybersecurity law. We are a start up SaaS business and Clayden Law provides services directly relevant to our industry and stage of development – as an added bonus they are also within our geographical area. Clayden Law has directly relevant expertise and experience which ensures that we get the most relevant advice at a great price. Nailing our terms and conditions, order form and maintenance and support SLAs at an early stage will reap significant rewards as we progress.”

Clayden Law demonstrates ‘exceptional industry knowledge‘, particularly in EdTech and advises on data protection, cybersecurity, and commercial matters, including digital content licensing, IP and provides notary public services for international transactions. Clients may benefit from department head Piers Clayden‘s complementary expertise in the fields of publishing and new media alongside his IT practice, which spans SaaS agreements and data privacy issues.

“The approach is friendly, collaborative (with lots of patience to explain concepts to us, as well understand our point of view), but most of all knowledgeable and quick to act when urgent deadlines suddenly appear. I was also extremely appreciative to experience what happens when something falls outside of their area of expertise. They reached out to their network and found us the right partner to work with in that area as well.”

“The 2 individuals at the company who I had the most time with both exhibited different styles that gave me confidence in both their knowledge and having our best interests at heart.”

“Exceptional industry knowledge and truly understands what the problem is we are trying to solve. They look at things from a business and operational standpoint and not just a legal precedent. They will always ensure that they think of potential risks, scenarios and events that may occur and add in coverage. They are a rare firm that looks at the operational, logistical and commercial needs of contracts and SLA documents as opposed to what are the legal implications.”
