Joss is an experienced professional negligence barrister, acting on behalf of claimants, defendants and insurers in claims against solicitors, architects and construction professionals.

Joss is consistently ranked as a leading junior in Chambers UK and the Legal 500.

His solicitors’ negligence caseload often links with his chancery/real estate practice, including claims concerning the negligent drafting of wills, claims surrounding the maladministration of estates and negligence in conveyancing.

In 2022 he appeared in Bracey v Curley [2022] EWHC 359 (Ch) in which the court considered the construction of a will, the alleged negligence of the will draftsman and the potential for a non-party costs order against the solicitors following a declaration for rectification.

Recent cases include:

  • T v FP (2024) – alleged negligence arising out of the drafting of a share purchase agreement for the sale of a components company. Joss acted for the defendant solicitors.
  • S v G (2024) – solicitors’ negligence claim concerning the conduct of litigation and defective drafting of a settlement agreement.
  • C v S (2021) – Joss represented the claimant company in a three-day trial before HHJ Ambrose against both its former solicitors and accountants concerning negligent tax advice following the sale of a golf club.

Early on in his career, Joss spent time on secondment at RPC LLP dealing exclusively with claims against construction professionals, including architects, surveyors, valuers and approved inspectors.

More recently he has acted for a number of claimants in claims involving Buyer-Led Development Schemes – principally against their former solicitors.
