The Property Disputes Team is led by the ‘superb’ Joanna Osborne.

Highly knowledgeable and experienced, Joanna is committed to identifying what really matters to her clients and to using her strategic insight and technical skills to create innovative, practical and commercially aware solutions. Her priority is always working out what is best for her clients, which usually means looking to exit disputes as quickly as possible and on sensible terms.

 

Joanna has experience of the broadest range of property disputes, covering both residential and commercial properties and sometimes a mix of the two. She encourages a creative and tailored approach by her bright and capable team. Although sometimes litigation is inevitable, the focus is on achieving the right commercial outcome for a client and exploring cost-effective ways of how this can be achieved. 

 

Joanna and her team carry out the highest quality contentious property work from the most complex to quite modest cases. Whilst having extensive technical skills, Joanna is astute, straightforward and tenacious. She receives a high level of referrals from clients, surveyors, accountants and other lawyers.

 

The Property Disputes Team has strong bonds with all departments across the firm, in particular the Property, Restructuring and Insolvency, Commercial and Private Client Teams, which means ready access to insights from very different legal disciplines. This collaborative culture has created very long-standing, trusted relationships, ensuring that strategy can be informed quickly by leading experts in other fields.

 

Joanna advises landlords, tenants, multiple national retailers, developers, local authorities, individual property investors and homeowners. Clients range from substantial PLC’s and ultra-high net worth individuals to small and medium sized businesses, entrepreneurs and private individuals. She particularly enjoys working closely with her clients, constantly learning more about people and businesses and their changing priorities; picking up vital insights which often help unlock seemingly intractable problems. Joanna is always on the lookout for intelligent bespoke strategies to achieve positive outcomes. She leads by example and champions a culture of awareness and great care and attention to detail, coupled with technical acumen and broad legal expertise.

EXPERIENCE
Joanna’s experience includes:
Breach of Option Agreement: Advising a charity on the failure by the purchaser of a nursery school under an option agreement to provide notice under an option to buy back the school. Bringing a claim for the difference between the sale price and the actual value of the property on the subsequent sale of the school.
Professional Negligence: Acting for claimants against property professionals in connection with the purchase and development of property. Advising on claims concerning construction professionals and claims against solicitors due to their failure to deal with landlord and tenant claims correctly, for example, serving adequate notices, such as to protect tenants’ right to renew in 1954 Act renewal cases.
Break Rights: Claims arising from defective (or the lack of) break notices served by both landlords and tenants or the failure to comply with conditions. Acting in professional negligence claims where solicitors have not advised correctly. Advising on claims for new business leases containing break rights on the grounds of redevelopment.
Property Purchase Issues: Claims involving misrepresentation and negligent misstatement in the purchase of property and the failure to complete.
Business Lease Renewals: Uncontested and contested applications for new tenancies including those opposed by landlords on various grounds and advising on the various tactical considerations, including in relation to interim rent and disrepair. Some parties are using proceedings as a negotiating tactic more than in the past.
Dilapidations Disputes: Advising both landlords and tenants, including clients with substantial property holdings, on the full range of dilapidations issues including advice on avoiding claims and on supersession and diminution in value under section 18(1) of the Landlord and Tenant Act 1927.
Landlord/Developer Defect Claims: Advising in relation to several luxury new-build developments of flats or houses, with numerous substantial building defects and fire safety issues. Claims where the landlord/developer has breached the covenant of quiet enjoyment and derogated from the grant of leases by seeking to restrict amenity and subsume land in further development.
Unreasonably withholding consent to assignment or subletting: Acting for landlords and tenants in cases where consent is sought for assignment or subletting. In one case the issue was whether a landlord could withhold consent on the basis that the premises were next door to the landlord’s head office and the proposed assignee was the Probation Service. In the end the assignment was permitted, but with concessions given as to how the premises would be used.
Boundary Disputes: Numerous disputes concerning failure to comply with the provisions of the Party Wall etc. Act 1996, also disputes concerning farmers moving boundaries, problems with roadways and issues arising in relation to the creation of rights to light.
Developer/Joint Venture Disputes: Advising on legal rights and obligations between joint venture partners, including claims for equitable relief arising from an estoppel.
Subsidence claims: Acting for homeowners in claims for and against neighbours, local authorities, new build developers and buildings insurers.
