About Us

What makes us different?

Mason Thomas Law was established in 2019 by a frustrated lawyer – Cathy Thomas.

Having worked in large corporate legal practices Cathy saw first-hand how poor internal communication could cause client frustration and result, in some cases, in a failed purchase. She wanted to do things differently.

In establishing Mason Thomas Law, Cathy has brought together a hand-picked team of legal professionals, all committed to open lines of communication, teamwork and a shared ethos of getting the job done and doing things differently.

We aim to provide the best service for our clients without delay.

If you are looking for a modern, efficient law firm with a difference – one that seeks to add value – then you have found it.

From the outset I wanted to create a commercial law firm that was different from everyone I’d worked for in the past. I take immense pride in the fact we’re different from traditional law firms. We’re a team with agility, thoroughness and communication at our core. Every member of the team is hands-on and knows what is going on with every deal. That’s the difference with Mason Thomas Law.” 

Cathy Thomas, Director and Lawyer, Mason Thomas Law

I have worked with Mason Thomas Law since March 2020 and been impressed. So much so that I am now using them for conveyancing on property purchases which we are then developing. Jo does exactly what she says she will do. They always get everything over the line on time for all deals we’ve been involved with and I couldn’t ask more than that.
Robert Askew, Managing Director of Ralane Properties
Thank you for your professional service and yet also your kindness during the purchase process. You were so thorough and we really felt you had our very best interests at heart. We really appreciate everything and will not hesitate to recommend you, you are a total credit to Mason Thomas Law.
Ms Sutherland

What clients say about us

"Working with Mason Thomas Law has been great. The team handled our lease renewal and it was as straight forward as they said it was going to be - it's been a quick and easy process."
Sue Crossland - Uncle Sam's

What clients say about us

"Huge thanks to the team at Mason Thomas Law. Twice previously we've bought and sold properties and we've not had the greatest experience with solicitors. The experience with Jo and the team at Mason Thomas Law was so different! Everything was slick and super speedy. They were great at explaining things in an easy to understand way, so we always knew what was happening and why. We would have no hesitation in recommending them to others. 5 stars and thank you so much."
Mrs L - Derbyshire

What clients say about us

"I obviously have a certain amount of knowledge and experience when it comes to the practical side of developing properties but having Jo to explain the legal procedures and really break it all down into layman's terms for us has been so helpful. She has been fantastic. I can pick up the phone to her any time – that's crucial when we have to turn deals around and make decisions quickly."
Matt Lipscombe - High Altitude Properties
