Monthly Costs Law RoundUp | January 2026

Monthly UK costs law update covering solicitor-client assessment, trust indemnity, Part 36 and fixed recoverable costs – TMC Legal
This month’s update covers fifteen decisions across the full breadth of costs practice. The Court of Appeal overruled Mundy on Part 36 liability-only offers, whilst the Senior Courts Costs Office delivered notable judgments on solicitor-client assessment, unless orders and fixed recoverable costs for police claims. Trust and estate practitioners received contrasting guidance on fiduciary indemnity following removal, and the Technology and Construction Court ordered a £43 million payment on account in the BHP dam litigation despite limited costs evidence.
