Charlotte and James – You’ll always be famous in my house!

“I recently lost my brother unexpectedly, and dealing with everything that followed was one of the hardest experiences of my life. My early experiences with family, police, hospitals, coroners, etc, were met with cruelty and dismissal at a time when I was already overwhelmed with grief.

The first law firm I hired only made things worse and couldn’t answer my questions, offered no real support, and I was left with more questions and a big bill.

A friend of my brother’s recommended this firm, and from the moment I reached out to them, everything changed. James McMullan (a partner) and Charlotte Barbaroussis (a solicitor) treated me with genuine care, compassion, and professionalism, guiding me through every step at a time when I truly needed it. Not only were my needs met, but they were also anticipated. I learnt so much along the way, and everything was explained in layman’s terms. Their support has been empathetic and exceptional, and I wouldn’t hesitate to work with them again.

If anyone is feeling uncertain about which firm to trust, I wholeheartedly recommend choosing them.

10/10 no notes!”

Dealing with a complicated estate

“From day one, we were provided with comprehensive details in a very professional manner, always received very prompt and detailed responses and were kept up to date throughout the entire process. Very efficient firm and would strongly recommend, many thanks to Charlotte Barbaroussis and James McMullan in particular”



Siobhan, June 2025

“A fantastic service from start to finish. Going through the probate process is a stressful and upsetting experience but James McMullan and his team were always contactable, proactive when required, reactive when required and so so understanding, empathetic and compassionate. I wouldn’t hesitate to recommend them to anyone going through a loss or indeed any legal matter that they could help with.”


Malcolm & Sheila Blackmore, May 2025

“My wife and I engaged RIAA Barker Gillette to prepare our wills and LPOA’s. James McMullan and Charlotte Barbaroussis were the epitome of professionalism – responding quickly, talking us through the legalese, clearly answering any questions that we had. The final documents were issued in very quick time. We would have no hesitation in recommending them to friends, family, and colleagues.”


Patrick, April 2025

“We had a long process handled by Charlotte & James from RIAA Barker Gillette. Even though we were outside the UK Charlotte & James we’re always available and we developed a great working relationship with them.
They gave sound advice, and we trusted their judgment.”


Leann Paris, March 2025

“From the beginning to the end, the support we have received throughout the case with all the staff members has been far more than we expected, we got kept up to date with every single matter, I have had stressful few years but Charlotte and her team have been very supportive and understanding.. I cannot fault anything, they have always gone far and beyond and always kept us up to date with everything that was happening.”


Nim, November 2024

“I highly recommend James McMullan and his team. They all did a fantastic job with helping me through a particularly difficult family situation. They are extremely professional, caring, and experts in their field.”

Probate and contentious probate


Tom Mulligan, September 2024

“Charlotte and James did a very professional job, replied promptly to emails, usually within an hour, and were available to meet when necessary. Key though is their specific experience in these areas [LPA, Probate and Wills].”

Wills, tax and trusts


Caroline, August 2024

“I’ve used RIAA for both Wills and Nuptial Agreements, as well as Deed in Trust. They are an intelligent and friendly group of people, looking out for their clients. The only ding is 1) change of attorneys mid-case due to the departure of previous and 2) an IT issue that delayed work for a few weeks. This is not the fault of the law firm so would still very much recommend.”
