Nikki Dundas will join the Edinburgh-based practice next month as a partner, along with associate Shona Brown and paralegal Laura Hamilton.
Dundas will also bring her secretarial support staff with her when she joins the firm.
Robin Hill, head of the private client department at Balfour & Manson, said: “After a busy and successful year, we were keen to strengthen the depth of the private client team.
“Nikki and her team are a very welcome addition to the department, bringing both experience and expertise as qualified practitioners with the Society of Trust and Executry Practitioners.
“These appointments will allow us to further develop the strength of services offered to our clients both in the private client and property fields.”.
Dundas added: “I am looking forward to working with an expanded department and in particular, given my interest in the affairs of the elderly, in having access for my clients to what I understand to be a unique client welfare service offered by the firm.”
