About Harriet

Whilst we would all like to avoid disputes and litigation wherever possible, that cannot always happen. If a dispute does arise, I am able to assist to try to resolve the issue in an efficient, commercial and cost-effective way.

Harriet assists businesses and individuals in managing and resolving disputes in relation to both commercial and residential properties, including, if possible, avoiding a dispute arising. 

Her areas of expertise include commercial landlord and tenant disputes, including arrears recovery and forfeiture of commercial leases. Harriet also works closely with our commercial real estate department on lease renewals, assisting with the statutory notice formalities and lease renewal proceedings, for both landlords and tenants. 

Harriet also has experience in dealing with residential property disputes, in particular in relation to applications for consent to alterations, interpretation of restrictive covenants, and service charge disputes.  

Harriet Allsop is conscientious, hard-working, thorough and responsive and willing to backup any written advice with additional verbal advice on a commercial basis to match the reality of any given situation. She is very professional and a pleasure to work with.

Notable cases

Harriet has been involved in:

  • advising a residential freeholder on a service charge dispute with a leaseholder, with the matter settling the day before trial

  • assisting on a high-profile rights to light claim (acting for the claimant/adjoining owner) which settled on confidential terms immediately before trial

Her client service, general level of service and level of sophistication are very strong. Her commercial awareness and vision are strong.
