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.

    Excellent advice and judgement

    Gregory Ostroff provided outstanding legal advice in a dispute with our former landlord over the return of a substantial deposit at the end of a ten-year commercial lease. What particularly impressed me was his excellent judgement and strategic approach. He knew exactly how and when to escalate the pressure on the landlord, while carefully avoiding unnecessary legal costs and the risk of being drawn into expensive litigation. Throughout the process, he demonstrated an exceptional ability to assess the situation, anticipate the landlord’s response and determine the most effective course of action. I would have no hesitation in recommending Gregory to anyone seeking an excellent litigation lawyer.

    We have used Streathers many times before personally. This time we required legal services for our little business. Gregory Ostroff dealt with our problem and after many months, the outcome was excellent. I would use these solicitors again and highly recommend.
