Thank you for your expert care and attention, it is refreshing to work with a solicitor who speaks plain English and can translate this into an effective legal document that I can now use to expand my business further both here in the UK and internationally. The patient manner in which you answered all my questions and then revised the Agreement to reflect my wishes and needs was also greatly appreciated.

Jonathan Hadley-Piggin of Keystone Law recently assisted us in the purchase of a new build Riva motor yacht. He also assisted the buyer in relation to crewing and flagging. We were impressed with Jonathan’s knowledge of the yachting market – a new venture for us, and his clear constructive advice which was invaluable, especially when dealing with numerous entities during the build and delivery process. We would have no hesitation in using his services again.

From day one of the appointment Jonathan drove the deal forward effectively, with outstanding response times to all parties. He is very knowledgeable in marine law which assisted greatly in what transpired to be a non-standard finance arrangement. Jonathan is both professional and approachable and we would highly recommend his services to others.
