Practice overview

Harriet Holmes is a property litigator, whose practice covers property disputes before the domestic courts and tribunals and, from time to time, from other jurisdictions.

Harriet has been recommended by the leading directories as a leading real estate practitioner since she was three years into practice. She has been repeatedly noted for being a formidable advocate who brings with her both technical ability and commercial astuteness. In 2021, Harriet was one of three finalists for Real Estate Junior of the Year at the Chambers & Partners Bar Awards.

Her practice comprises: real property; landlord and tenant; property insolvency; trusts of land and settled land; and professional negligence cases arising from those areas. Harriet enjoys, and is known for, being a specialist in some more unusual or niche areas of land law, such as mines, minerals and manorial rights and rights of light, as well as for dealing with complex commercial property / development-related disputes. Fossicking around archives is something she has had cause to do (and enjoys). She is an expert in rights of light and in the property aspects of telecommunications law and is regularly instructed by household name mobile phone operators and infrastructure providers.

Harriet has appeared in her own right in a range of domestic courts and tribunals, including the Court of Appeal, and has acted in disputes before the Privy Council and Supreme Court.

She sits on the Bar Council as part of the Regulatory Review Working Group and is a contributor to Hill & Redman’s Law of Landlord and Tenant.

Property

Harriet is a well-known property junior, who advises on and acts as sole counsel or as part of a counsel team in a wide range of real estate disputes.

She was recognised as an ‘up and coming’ junior for real estate litigation after only three years in practice and has since been ranked as a leading property practitioner by all the leading directories – Chambers & Partners, Legal 500 and Who’s Who Legal.

Harriet was, by some margin, the most junior of the three finalists for Real Estate Junior of the Year at the Chambers & Partners Bar Awards 2021.

She is a specialist property litigator with extensive experience of the ‘usual’ issues which arise (such as 54 Act matters, break clauses, easements and freehold land covenants etc.) but one who has experience of some more unusual or niche areas of land law (such as mines and minerals, pre-1925 Act land law, and rights of light) and is used to dealing with property cases which stray into other areas, such as property insolvency and trusts of land matters.

Harriet acted as junior counsel for the successful parties in the two important recently reported Court of Appeal cases of Bath Rugby v. Greenwood, which concerned annexation of restrictive covenants, and Wynne-Finch v. Natural Resources Body for Wales, a case concerning the interpretation of mines and minerals reservations and inclosure acts (and awards) and adverse possession of sub-strata.

More recently, she has been acting (with John McGhee KC) for the developer of a large office building in the City of London in a rights of light dispute, Adjoin Limited v FortyTwo House Sarl. She is also instructed as sole counsel for a claimant alleging infringement with rights of light to a commercial building in Birmingham. These cases build on Harriet’s previous experience of rights of light, acting in Beaumont v Florala at the interlocutory stages and for the developer in a rights of light dispute concerning a tower development in Leeds.

Harriet has acted in property disputes in the main domestic courts and tribunals through to the Supreme Court and Privy Council. She also has experience of property disputes from the Caribbean jurisdictions and on the Channel Islands.

She is a member of the Chancery Bar Association and the Property Bar Association. She sat on the PBA’s committee (and as the association’s Bar Council representative) for a number of years and is a contributor to Hill and Redman’s Law of Landlord and Tenant.

Her experience includes:

  • Commercial and residential landlord and tenant, including ’54 Act renewals, rent review litigation and arbitration, forfeiture, break clauses etc.

Professional liability

Harriet regularly accepts instructions in professional indemnity matters, particularly those with a property dimension. She acts both on her own account, or as junior in more substantial matters.

In the year between bar school and pupillage, Harriet worked at a solicitors’ firm as a fee earner in group litigation against various conveyancing solicitors’ firms for failure to adequately advise on right-to-buy conveyances. This, together with her experience as a property litigator who has considerable experience of development disputes, makes her well-placed to deal with solicitors’ negligence claims involving conveyancing.

Notable recent instructions include:

  • Acting for the developer claimants in a multimillion-pound claim against three firms of solicitors (and the administrators of an estate of a solicitor) relating to a development of residential flats which had been sold off-plan and a ‘scheme’ which attempted to avoid unilateral notices placed on the title to the development site by the flat purchasers (led by Martin Hutchings KC).
  • Acting for and advising a claimant suing for damages relating to an alleged failure to properly terminate an agreement with a telecommunications operator (led by Martin Hutchings KC).
  • Acting as sole counsel for the claimant developer in a claim against transactional solicitors concerning advice given in respect of a development agreement and conveyance of the development site.
  • Advising on the prospects of a claim against conveyancers for failure to advise on various title issues, including rights of way and services easements, over a residential development site.
  • Acting for defendant solicitors in a multimillion-pound professional negligence claim concerning alleged failures to advise of risks of a non-party costs order in a multimillion-pound claim in deceit and for breach of public procurement rules (led by Jonathan Seitler KC).
  • Acting for the tenant of commercial premises in a multimillion-pound claim against their solicitors for failing to exercise a break clause in a lease of the tenant’s headquarters (led by Jonathan Seitler KC).
