Gregory Ostroff

Gregory focuses his practice on high-value and complex commercial and property disputes. He has extensive trial experience, and has established a strong track record in dealing with high-profile and often sensitive disputes to trial, including:

  • Acting for the successful Claimant in the 4-day trial of Maria Jesus El Massouri v Omani Estates Limited [2024] EWHC 534 (Ch), reported in national newspapers, including The Times and The Telegraph. The case involved important and evolving areas of law, the new adverse possession regime, estoppel and remedies for possession of land not capable of occupation.
  • Acting for 6 successful Claimants in the 4-day trial of Benton and Others v Paes and Others (2023, County Court at Central London), also reported in national newspapers. This case related to a major boundary dispute concerning a 20ft disputed strip, dismissal of a counterclaim for a prescriptive easement and indemnity costs.

Gregory is also frequently instructed on urgent High Court injunctive relief. This has involved obtaining a without notice interim injunction to protect an MOD “X” listed site by restraining the landlord from turning off electricity; an interim injunction to restrain acts of trespass and nuisance at another sensitive defence contractor site; an injunction to enforce restrictive covenants against former employees engaged in a cybersecurity company, compromised by undertakings to Court; and a without notice injunction to prevent repeated break-ins to residential tenanted premises.

He has a broad civil litigation practice, encompassing loans, guarantees, secured lending, defendant mortgage possession work; contract claims, misrepresentation, professional negligence; landlord and tenant work, both residential and commercial, to include 1954 Act business lease renewal and termination; issues relating to trespass, adverse possession, boundaries and easements; and estate and probate matters.

Gregory understands that litigation is expensive, time consuming and stressful and, where possible, looks for opportunities for an early resolution, including by mediation.

Over the course of years Gregory provided unwavering, strategic and sound legal advice which contributed significantly in bringing a very complex dispute to a much needed close. He often went over and above, delivering against short deadlines and in highlight stressful situations whilst keeping me, his client, always up to speed with clear and supportive direction…I have no hesitation in highly recommending Gregory going forward. Polished service all round.
