Simon Williams
Call: 1984
Barrister

Simon Williams has a property, commercial and professional negligence practice consisting of advocacy, drafting, advisory work and mediating in a range of property and business-related matters. More than 30 years at the Bar have equipped Simon with the sort of experience which for some time has been recognised by the leading legal directories. As an advocate he appears frequently in the Business and Property Courts of England and Wales, in the Court of Appeal, in the First Tier and Upper Tribunals, and in mediation and arbitration. In February 2009 he appeared in one of the last cases to be heard by the Judicial Committee of the House of Lords.
Simon’s property practice extends to disputes relating to title, easements, boundaries, covenants, trusts of land, nuisance, conveyancing, landlord and tenant (commercial and residential), leasehold enfranchisement, mortgages, construction contracts and property-related insolvency.
He is instructed by or on behalf of private individuals, companies, institutional clients and a variety of property professionals and is frequently to be found in all the domestic courts and tribunals where property disputes are heard whether on applications, including for urgent interlocutory relief, at trial or on appeal, or alternatively in mediation or arbitration.
Simon is recommended as a leading junior for his property litigation expertise by both Chambers UK Bar and The Legal 500 UK Bar. The directories say that he has “in-depth knowledge of property law and is a persuasive advocate” (Property Litigation, The Legal 500 UK Bar 2020), “very user-friendly and has an innate ability to remain calm during a crisis” and “thorough, inventive and always communicates in a clear and unfussy way.” (Real Estate Litigation, Chambers UK Bar 2020).
He has appeared in a number of significant property cases including:
- Baxter & Others v Stancomb [2018] EWHC 2529 (Ch) – Acting in relation to a TOLATA application in the High Court concerning a property which was part only of a large estate and whether it should be ordered to be sold to enable the sale of the whole estate to go ahead
- Food Converters Ltd v Newell [2018] EWHC 926 (Ch) – Acting for the Appellant who was seeking to overturn the trial judge’s conclusion that, on the particular facts of the case, he had not taken factual possession of land in question and had not therefore dispossessed the paper title owner of the land for the purposes of the transitional provisions of the Land Registration Act 2002

- at trial on behalf of a client whose property was severely damaged when a fire which started accidentally in a neighbour’s pottery studio spread to her property
- at trial on behalf of a property owner on the question whether a wall in which she had inserted a window and a boiler flue was a party wall and therefore whether what she had done amounted to a trespass and/or a nuisance and, if so, whether the appropriate remedy was a mandatory injunction or damages or both.
He is also currently advising:
- the occupants of premises whose neighbours are conducting a business which gives rise to a potential nuisance
- developers of land the subject of a restrictive covenant concerning the types of building permitted on the land
- a vendor of land seeking specific performance of the contract by the purchaser who claims that the contract is unenforceable because it does not satisfy the requirements of section 2 of the Law of Property (Miscellaneous Provisions) Act 1989

He appears regularly in the Commercial, Business, TCC, Insolvency and Companies lists of the Business and Property Courts of England and Wales on both interlocutory matters, including applications for urgent interim relief, and at trial, and in the Court of Appeal.

He has recently acted for a company whose workshop was flooded following the admitted negligence of a contractor involved in the renovation of adjacent pipework and is currently acting for a purchaser of property whose conveyancing solicitor failed to protect her interest in the property pending a delayed completion resulting in part of the property being conveyed to a third party.
He has also recently acted on behalf of purchasers of property whose solicitor negligently failed to advise them of the existence of a report about damp in the building in which the property was situated.
Current instructions include those on behalf of a litigant whose solicitor failed to advise him as to the inadequacy of a statement prepared by him for a trial which resulted in an order for costs thrown away to be paid to the other side, significant wasted costs on his own side and other consequential losses.
Simon is again recommended as a leading junior for professional negligence work in the latest edition of The Legal 500 which describes him as “sound, clear and analytical”. The 2015 edition of the Legal 500 reported the comment from clients that “He is first class and really knows what he is doing”
