Shoosmiths is providing legal advice to ambitious convenience chain One Stop on its move into franchising.
The national law firm, which has acted for the convenience store chain for around 10 years, will help it open up to 20 new franchises by the end of February.
Five pilot stores have already opened successfully in England and Wales.
One Stop says its franchise model is aimed at 'good independent retailers who want to develop a long-term retail partnership and take their business to the next level'.
Led by commercial, Shoosmiths already provides the West Midlands-based chain with a full range of legal services, including real estate, property litigation, regulatory, employment, and intellectual property.
National head of commercial David Jackson said: "We've lots of franchising experience that we'll be bringing to bear to help this long-standing client realise its growth ambitions.
"We regularly advise both franchisees and franchisors on high profile franchise arrangements, and the results of deals our specialists have completed can be seen throughout the UK - on the high street and even in motorway service areas."
Shoosmiths has advised several household name companies on franchising, including Alliance Boots, Marston's, TK Maxx, Poundland, WHSmith, Thorntons and Roadchef.
Jackson added: "Our team understands that franchising is an excellent way for established businesses to expand into new territories and increase brand awareness without all the risks associated with organic growth. "
He explained that One Stop is looking for franchise partners with established businesses turning over at least £10,000-a-week, sales space of 1-3,000sq ft, and an excellent credit history. It will offer five-year agreements.
Based in Brownhills, One Stop has more than 700 stores and outperformed the convenience store market by 3% in 2012. Its sales in the year to February 2013 were more than £720m.
