The deal sees the transfer of responsibility of around 1,500 wills to GSB.

Tony O’Malley, managing partner of GSB, said: “This is a really solid step for us. We’ve been focused on growing in the right way – and being chosen by Shoosmiths to take on this work reflects the strength and stability we’ve built across the business.

“We’ve invested heavily in the last couple of years, revamping our whole IT infrastructure including moving to a cloud-based system, replacing all our telephony and will shortly be moving our case management system to Denovo. This all gives us more flexibility, dynamism and the platform to grow further.

“It fits well with our direction of travel, expanding our private client base and deepening our presence in Edinburgh, without losing the personal approach that’s always been at the heart of what we do.”

“We’d also love to hear from firms looking to exit the private client market or sell their will bank.”

The deal follows a decision by Shoosmiths to exit private client services across the UK, including Scotland, and focus on its core commercial offering.

Transition support is being led by GSB’s Catriona Miller, a private client solicitor with more than 30 years’ experience, and a former partner at Anderson Strathern. She will be supported by head of private client, Kwan-Nga Yeung.

Ms Yeung said: “Our first priority is ensuring a smooth transition for clients. Many may not have reviewed their wills in some time, so our experienced team will be on hand to guide them through any updates they may wish to make.”
