About us

Welcome to the Serious Law corporate site. Recommended by The Legal 500, we are one of the UK’s leading law firms in the field of catastrophic injury claims, with a particular emphasis on high-value, difficult liability cases.

Recommended by many leading organisations to act in such cases, we have achieved numerous multi-million pound settlements in cases of the utmost complexity, and have dealt with some of the largest cases to have taken place in the UK to date. A number of these high value settlements have been achieved in cases that were rejected by other firms, having concluded that there were insufficient prospects of success.

We are dedicated to excellence in all areas of client care, and offer a nationwide face-to-face client service that is delivered professionally and sensitively. This has helped the practice to develop close relationships with leading charities, spinal centres, medical and care experts, specialist barristers and other leading professionals in the field of serious and catastrophic injury.

In order to help our clients rebuild and regain control of their lives, we offer an all-encompassing service that not only includes legal assistance, but also the facilitation of rehabilitation, vocational training, housing adaptation, nursing care, and more.

As part of our corporate strategy, we may engage with prospective clients and their families utilising our 'Serious Injury Law' trademark and trading style. Comprehensive details of our services are available on the seriousinjurylaw.co.uk website.

‘Serious Law LLP’ is established. Originally known as 'Sherrington & Co.’ and subsequently 'Sherrington Law', it is one of the first law firms in the country to work exclusively in the field of personal injury.


As the firm begins to deal with an increasing number of very serious and catastrophic injury cases, a specialist 'Catastrophic Injuries Unit' is established in order to cater for the very complex nature of this work.


The business is re-branded as Serious Law LLP to reflect its increased focus on serious and catastrophic injury cases.


The firm is awarded both the Lexcel and Investors In People accreditations on its first application. All subsequent reapplications have been successful.


The inaugural 'Serious Law LLP Charity Golf Classic' takes place on behalf of Spinal Research at The Belfry's Brabazon Course.


Having achieved numerous multi-million pound settlements over the years, a landmark is reached as a case is settled by Serious Law LLP with a capitalised value in excess of 10 million pounds.


The firm is admitted to the prestigious Legal 500.


The launch of ALP Law is announced, a new ABS venture in conjunction with Allianz. With a 2013 annual turnover of £91.6bn, Allianz is the world’s largest insurance company. Allianz selected Serious Law LLP because of our “proven experience and technical expertise”.

Core values

At Serious Law, we are dedicated to excellence in all areas of our practice. We recognise that the success of our firm is determined by our relationships with all those we encounter, whether they are clients, employees, or business partners. The firm's core values underpin this pursuit:

Professional Excellence

In order to maintain our position as leading experts in the field of serious and catastrophic injury cases, we continually strive for professional excellence.

This extends beyond legal expertise, and also encompasses a deep understanding of the practical and medical implications of serious injury. 

Personalised Support

Our clients must often allow our lawyers access to very personal and sensitive areas of their lives. It is important that this intimacy is not taken for granted.

Every situation must be treated as unique, because every case will have its own particular nuances and bespoke requirements. 

Our ultimate aim is to establish close relationships with our client and their loved ones. These relationships will continue throughout the lifetime of a case, and beyond.


We recognise that our clients will want to know exactly what is happening with their case at all times. It is through regular and transparent communication, in whatever way they feel most comfortable, that we can build a trusting and long lasting relationship.


Continuous Innovation

Whilst always staying abreast of changes in the law, we must embrace innovation as a means of progression and development.

We must be dynamic and take decisive action; balancing our forward-thinking and long-term vision with the requirements of the here and now.


The firm has a first-class reputation for honesty and integrity. We aim to lead by example in this regard, and we recognise that our actions must reflect this at all times.
