We instantly clicked and she ‘got’ what we were all about

Having never been a business owner before I was so grateful when I came across Karen Holden and A City Law Firm. We instantly clicked and she ‘got’ what we were all about. Karen and her team really work hard to understand your business and treat you as a person, not just a number- so refreshing . I can’t thank Karen enough for putting us back on track, teaching us the basics and expertly formulating our shareholders agreement and applying swiftly and professionally for our IP. Karen’s understanding of start-ups and funding options is second to none. I foresee that A City Law Firm will be holding our hand and being part of our journey for many years to come.

a high settlement which exceeded  my expectations

A City Law firm negotiated a high settlement which exceeded my expectations. Before I approached them I was struggling in knowing how to cope with an increasingly bitter and complex situation which had developed at work. I was scared of going to lawyers and the costs that could be involved but when I sat down in the initial meeting with Karen and Bianca they were so understanding, empathetic and human and explained everything clearly, professionally and with such kindness. It has meant I can start a fresh on my new business.

My sincere and heartfelt thanks

Going to work had become unbearable. I knew I was being bullied and treated very unfairly, but felt powerless to take any action. I found A City Law Firm online and received a quick response and after speaking to Karen, I felt immediately reassured that my treatment was unacceptable, and there was appropriate action that could be taken. I found them to be very understanding and supportive during this difficult time. My confidence has been restored and I look forward to my future and working with pride again. My sincere and heartfelt thanks.


passion and commitment to the LGBT community

A City Law Firm. A refreshing approach to legal information. A City Law Firm offers all the help and guidance you need but with passion and commitment to the LGBT community. A proud partnership that I believe will last a lifetime.


Your success in  negotiations with the opposition

Once again I would like to thank you for your patience, understanding and advice over this very difficult time. I very much appreciated your attention and efficiency in dealing with me and your success in negotiations with the ‘opposition’ which came to such a satisfactory conclusion.” ”


A watertight contract of employment for my staff

The work that Karen did for me in writing a watertight contract of employment for my staff member was done quickly and efficiently. She actually worked over a weekend to ensure that the copy was ready for the Monday morning. Thanks Karen!” ”


Efficient, caring, quick and very responsible

I am so pleased with Karen’s work and help. She was so efficient, caring, quick and very responsible. Whatever she promised she produced it. I will definitely recommend her. Very lucky to have her as my solicitor.
