The recent Court of Appeal case involving Topland Limited and Smiths News Trading Limited was a salutary lesson about the strict rules that protect guarantors and the perils of forgetting them.  The facts of the case were relatively simple:  Topland owned a commercial property, leased to the rather aptly named Payless DIY Ltd, which became insolvent.  Topland brought a claim against the tenant’s guarantor, Smiths, for arrears of over £280,000 and required them to take a new lease for the remainder of the term.
