Mr Inglis, a property law specialist who has been with Mitchells Roberton for 30 years and was made a partner in June 2005, said: “Despite the many changes in the Scottish legal scene, Mitchells Roberton has always been a fiercely independent firm and plans to remain so.

“Independence and continuity are vital to how we operate as a successful family-friendly firm, which promotes a work-life balance for all members of our team, while consistently providing high quality service to our clients.

“I should like to thank my fellow partners in honouring me with their trust and in particular, my sister Morag, who has done an exceptional job shaping Mitchells Roberton into the firm it is today.”

Ms Inglis, a commercial law specialist who will continue as a consultant to the firm, added: “Ronald and I are fourth-generation lawyers so it is in our bones. Like me, he trained here and has remained with the firm ever since so he fully supports the ethos we have and which we all value.”

Both are children of Alistair Inglis, professor of conveyancing at Glasgow University from 1978 to 1993, who helped implement the map-based registration of title system in Scotland and was a former dean of the Royal Faculty of Procurators in Glasgow.
