William has expertise in advising trustees as to the identification of charitable trusts, their purposes, public benefit, construction and the exercise of powers under them.

In doing so William advises upon matters including the exercise of powers to sell or lease, the application of the doctrine of cy-près, the duties of trustees and the role of the Charity Commission.

William frequently acts for charities as beneficiaries under wills and trusts in all matters arising in respect of their beneficial interests and any challenges to them.

Examples of recent work in this area include:

• Advising local authorities on trusts governing civic buildings and land including pleasure gardens, clinics and community care institutions, concert halls and libraries

• Advising charity trustees on the potential development of a city-centre cricket ground held upon charitable trusts.

William has handled a variety of commercial work both advising and in litigation, across a wide range of contractual disputes in the Chancery and Queen’s Bench Divisions as well as the County Courts, Commercial Court and the Court of Appeal.

William has acted for a range of clients from well-known banks and life assurance companies to large and small business involved in trade, manufacture and retail. He has particular experience of the sale of goods and supply of services, contracts of agency (estate agencies, recruitment agencies and financial consultancies), franchise agreements, seeking and resisting injunctive relief in cases concerning covenants in restraint of trade and misuse of confidential information, contracts of guarantee (enforceability and construction of terms), civil fraud, bailment and conversion, debt recovery and restitutionary remedies.

William has developed an expertise in disputes relating to contracts vitiated by mistake and in claims relating to actionable misdescription of goods, including innocent, negligent or fraudulent misrepresentations at common law and actions under the Misrepresentation Act 1967.

William has been complimented for his ability to work quickly in cases of urgency, seeking interlocutory relief where a client’s commercial interests require it, and has considerable experience of seeking and resisting applications for freezing orders.

William has acted in a wide range of partnership disputes, with particular emphasis on the existence and obligations in informal partnership agreements and partnerships at will, the breakdown of joint ventures, dissolution, orders for sale of (and rights to buy) partnership property, secret profits, analysis of partnership accounts, expulsion and retirement, the duties of partners, and taking steps to protect confidential information and preserve partnership assets on an urgent basis.

William has acted in respect of joint ventures in a wide range of commercial spheres, but has developed particular familiarity with farm business partnerships including questions of family land ownership (often over several generations) and agricultural tenancies and subsidies, as well as partnerships of accountancy and IFA practices, medical practices and in the information technology spheres. William also has experience of unfair prejudice petitions in the context ‘quasi-partnerships’ where small private companies are used as vehicles for joint ventures.

William is also frequently instructed to advise on, and draft, terms in partnership agreements.

William acts for both claimants and defendants, with particular experience in claims against solicitors, building contractors, valuers, local authorities, surveyors and architects.

William has expertise in claims of negligence relating to conveyancing transactions, defective construction of buildings and the detection of such defects, valuations of real property and businesses, and the drafting and administration of trusts and wills by solicitors. William has recently given a series of seminars on liability of solicitors to potential beneficiaries in the preparation of wills under the principal in White v Jones.

A number of recent cases have involved defective dispositions of land, failures in the creation of trusts, and failures in the administration of funds held upon trust including failures to invest trust monies.

William is frequently instructed to represent and advise clients at mediation, in a wide range of disputes covering his areas of practice. He is commended particularly for his persuasive and tactically astute opening position statements and speeches, and for his guidance on changing circumstances and arguments, the inclusion of matters of compromise outside the ambit of the proceedings and an adaptability in testing the case of opponents whilst seeking common ground.

William is also involved in questions of determination by experts, international and domestic arbitration, advising on the enforceability and construction of arbitration agreements, as well as the process of arbitration itself and its relationship with any court proceedings (from interim remedies, stays, appointment and replacement of arbitrators, enforcement and appeals).

Much of William’s work involves an international element. He frequently acts for or against parties outside the UK and his work often involves questions of the proper law governing a contract, jurisdiction, and the interpretation and effect of regulations and conventions concerning enforcement of judgments.

This international element spans the entire scope of William’s practice, from commercial litigation to private wealth, estates and trusts (such as estates and settlements including property in more than one jurisdiction) which often involve questions of private international law and the conflict of laws.
