The People at Marr-Johnson & Stevens

Prosper joined MJ&S after graduating in September 1990 and worked alongside his father, Simon, on enfranchisement matters, for several years. The founding partners have both retired from the partnership, and Prosper now runs the firm with Tim Martin.

Prosper jointly heads the residential valuation department with Tim, and carries out professional valuation work for enfranchisement, taxation, rent review, matrimonial and dispute purposes. The majority of his work is within the leasehold enfranchisement field on houses, flats and blocks of flats. Prosper frequently advises clients on the Bedford, Cadogan, Church Commissioners, Crown, Day, Grosvenor, Howard de Walden, Ilchester, Phillimore, Portman, and Wellcome estates, as well as tenants of other large property companies such as the Freshwater Group and Scottish Widows Investment Partnership. He has acted as an expert witness many times in front of tribunals as well as for mediation purposes.

Prosper won Valuer of the Year at the Enfranchisement and Right to Manage Awards 2012.

After a short service commission in the cavalry, Tim joined Grosvenor in 1991. He qualified as a chartered surveyor in 1998, joined MJ&S in 2002, and was quickly made up to partner the following year.

Tim jointly heads the residential valuation department with Prosper, and carries out professional valuation work for enfranchisement, taxation, rent review, matrimonial and dispute purposes. He has particular expertise in all matters relating to Leasehold Reform, but it is his attention to detail along with a strict interpretation of the statutory legislation that provide him with the greatest negotiating leverage. 

Tim frequently advises clients on the Bedford, Cadogan, Church Commissioners, Crown, Day, Grosvenor, Howard de Walden, Ilchester, Phillimore, Portman, and Wellcome estates, as well as tenants of other large property companies such as the Freshwater Group and Grainger Trust. He has acted as an expert witness many times in front of tribunals.

Tim won Valuer of the Year at the Enfranchisement and Right to Manage Awards 2014.

Having previously worked for John D Wood, Marie joined MJ&S as a property manager in September 2004 to run our client property portfolio. However she dedicated herself to further studies and qualified as a chartered surveyor in October 2008. Marie now works in the valuation department and advises clients on a range of residential property, but primarily the firm’s speciality of lease extensions and enfranchisements, acting for both landlords and tenants. Marie is well respected within the Leasehold Reform community and has appeared in front of the Leasehold Valuation Tribunal (now the First-tier Tribunal) on several occasions very successfully.

Marie was Highly Commended as Young Professional of the Year at the Enfranchisement and Right to Manage Awards 2013.

Oliver has worked in Central London residential property since 2007, and at Marr-Johnson & Stevens since 2012. He is a partner in the firm and is a qualified Chartered Surveyor and RICS registered valuer and holds a Master of Arts degree in Property Investment and Finance. His principal focus is residential valuations in Prime Central London but he also carries out work elsewhere across the UK for larger cases or clients. The majority of his work comprises:

• Formal RICS compliant ‘Red Book’ valuations for Capital Gains and Inheritance Tax purposes and matrimonial disputes,
• Pre-purchase valuations for HNW individuals, family offices and their advisors,
• Leasehold Reform Act valuations and negotiations for enfranchisement of houses and blocks of flats, and lease extensions of individual flats, and
• Landlord & Tenant valuations for consents to alterations, change of use and rent reviews.

Oliver also acts as an Expert Witness and has had recent successes acting for landlords and for tenants before the First-tier Tribunal (FTT) and defending an appeal to the Upper Tribunal.

Prior to taking his Masters, Oliver held a commission in the Grenadier Guards performing both operational and ceremonial duties, latterly serving in the Royal Household for two years as an Equerry to HRH the late Duke of Edinburgh.

Away from the office Oliver lives in Leicestershire with his wife and two daughters. He is a keen sportsman, Francophile and chef, and even perhaps an aspiring Master Chef contestant!
