Notable Cases

TOSB v B & WE: Represented the Claimant mortgage lender in seeking possession of a property on the basis of mortgage arrears. The 2nd Defendant defended the claim on the basis that she had entered into the mortgage as a result of the undue influence of the 1st Defendant and that the Claimant had been on constructive notice of the same. The Court found that the Claimant lender was not on notice of any undue influence and therefore granted possession of the property together with judgment for balance outstanding under the mortgage.

Future Properties SE Ltd v Favorite (Restaurants) Ltd [2022] EWHC 3052 (Ch): Represented the Defendant tenant on a rolled up application for permission to appeal and appeal against a determination of the rent payment under a new business tenancy (Landlord and Tenant Act 1954). The appeal was allowed in part in relation to the assessment of the Respondent’s costs.

FM v TB Limited: Represented the Defendant landlord in proceedings pursuant to Part II of the Landlord and Tenant Act 1954. The Landlord sought to oppose the grant of a new tenancy on the basis of grounds (a), (c) and (f) within section 30(1) of the Act. In particular, there were disputes as to whether an extraction system installed by the tenant caused a nuisance in breach of the lease, whether the tenant had failed to comply with health and safety legislation, and whether a denial of access by the tenant had prevented the landlord from taking the steps necessary to be in a position to successfully rely on ground (f).

Bhat & Anor v Patel & Anor [2021] EWHC 2960 (Ch): Represented the Claimant landlords in a claim for possession of commercial premises operating as a GP surgery. The claim was defended on the basis that the Defendants claimed to have acquired a beneficial interest in part of the premises. The defence was dismissed at trial and possession granted. On appeal, relief from forfeiture was granted in respect of part of the premises only, resulting in the unusual situation of the Claimants being entitled to repossess only part of the premises.

Silkman v Love: Successfully represented the executor of an estate in obtaining an order for sale of co-owned property in the name of the deceased and her ex-partner pursuant to section 14 TOLATA. The case was reported in the national news.

NCP v Wonder Wash: Represented the Defendant in a claim to possession of part of a car park, which was used by the Defendant to operate a car wash. The case involved a legal dispute as to whether the Defendant occupied the car park under a lease or a licence.

(1) Mansing Moorjani (2) Samir Yousf (3) Lena Yousf (4) Nadia Seifeldin v (1) Durban Estates Ltd (2) Ivor Court Freehold Ltd [2019] EWHC 1229 (TCC): Application by the 1st Defendant to strike out the 1st Claimant’s claim for damages following the freeholder’s alleged breach of its repairing obligations on the basis that it was barred by cause of action estoppel and merger

Butt v Rashid: Successfully represented the Claimant in a claim for wrongful interference with goods, where the property occupied by the Claimant was repossessed by the Defendant

Wilkins v Mund: Successfully obtained a restriction over property held in the sole legal name of the Respondent on the basis of a beneficial interest.

Bowes v Norman: Successfully represented the Claimant in a TOLATA matter in obtaining a declaration that a property was owned in equal shares and an order for sale.

Walton Lodge Veterinary Group Ltd v (1) Thomas Knight (2) Roger Michael Knight and Mrs Natalia Wickens (as personal representatives of Arthur Edward Knight deceased): Advised in a dispute over what amounts to a ‘forfeiting event’ where the tenant was a company controlled by the lessee rather than the lessee itself. The advice provided facilitated settlement.

Arora v Yazdi: Successfully represented the Applicant in reducing service charges payable by a residential long leaseholder in proceedings before the First Tier Tribunal (Property Chamber).
