Our history
Damon Parker founded Harcus Parker in 2019 with the vision of creating a world leading firm combining commercial discipline with access to justice.
He was a pioneer when it came to running successful group actions in the UK and secured the first financial services Group Litigation Order. With a successful track record of running large-scale collective actions against companies like Tesco and Lloyds TSB at Harcus Sinclair LLP, Damon was instrumental in establishing the use of litigation funding to enable claimants to pursue their claims.
Harcus Parker has built on those foundations, adapting to a changing legal landscape and delivering the highest quality client service. They have the operational infrastructure to run high volume claims and a strong claimant acquisition and client communications capability.
Since 2019, our firm has grown from a team of 12 to more than 50 professionals. At the same time, our practice has developed
Large group claims require more than legal analysis. They require systems for onboarding claimants, collecting and verifying data, managing communications, protecting client information, monitoring limitation, and progressing claims efficiently. Harcus Parker has built a legal operations capability around the demands of high-volume litigation.
We work with funders, insurers and strategic partners to structure claims responsibly, so that our clients have the best chance of securing an outcome they are happy with.
Our social impact
We are committed to bringing about positive social change, raising awareness of legal rights, and encouraging more people to access justice.
Many of our cases highlight critical failings in regulatory oversight and corporate governance, societal issues such as the gender pay gap, and address major financial scandals, instances of hidden conflicts of interest, fraud, and ‘greenwashing’. Our cases regularly capture the attention of national and international media, with our lawyers invited to share insights and updates – you can read more here.
