Seth successfully resisted a highly unusual and complex post-trial application to amend a claim to plead commercial fraud. The application was dismissed and indemnity costs were ordered.

Successfully defended a claim under a deed for £1.3m. Seth successfully argued that (i) estoppel by convention could not be used to remedy a deed that was flawed on its face, and (ii) any estoppel could only operate within a contract to broaden its terms and not to perfect an agreement that would otherwise fail.

Successfully obtained a grant of a new commercial tenancy, overcoming the landlord’s objection under s30(1)(g) of the LTA 1954. Seth was able to establish through cross-examination that the landlord did not have a ‘settled’ intention for the purposes of the act as there was no reasonable prospect of being able to bring their intention about.

Sole counsel for the Claimant in a claim arising from out of a disputed business sale valued at c. £3m. Settled following a fully contested CCMC.

Secured judgment in excess of £100,000 in a case concerning non-payment of a hire-purchase agreement for industrial plant.

Obtained business rates liability orders for totalling £110,000 following a contested trial.

Represented the Claimant in a two day civil fraud trial. Following extensive cross-examination of a senior finance manager, Seth successfully established a case of common law bribery.

Successfully obtained 80% of the marital assets for a client following a contested trial. Seth was successful in establishing a conduct case enhancing his client's share of the martial asset pool.

Seth was able to reveal systematic falsification of disclosed bank accounts, payslips and sick notes via three contested third-party disclosure applications with full costs being awarded to the Applicant. The case settled after a successful FDR.
