Notable work & expertise
Ciaran has acted on numerous professional negligence claims against all manner of professionals, including complex and high-value claims brought by companies and individuals against solicitors, accountants, financial advisors and surveyors.
Recent Work
- Acting for two private individuals in a professional negligence claim against a firm of solicitors in relation to advice given to them regarding interest rate hedging products that were later the subject of a review by the Financial Conduct Authority. Settled without the need to issue court proceedings on terms which recovered significant damages for our client and a payment toward their legal fees.
- Acting for an insolvency practitioner in a professional negligence claim against a firm of solicitors in relation to a failure to advise on the application of the statutory charge under the Insolvency Act 1986. Secured an early settlement by which the firm of solicitors agreed to indemnify our client for a six-figure sum it had been ordered to pay to its opponent in court proceedings because of steps taken based on the negligent failure to advise and to meet our client’s legal fees.
Ciaran has vast experience of dealing with all manner of contractual disputes across all sectors and in any number of different contexts, including on cross-border disputes. He has taken high-value contractual disputes to the High Court and won but also regularly achieves favourable outcomes for clients at the pre-action stage, whether by correspondence or the use of alternative dispute resolution, recognising that pragmatic and commercial settlements have real value to clients.
Recent Work
- Acting for a specialist carbon composites manufacturer in bringing a six-figure debt claim against its customer and defending a counterclaim in breach of contract relating to the production of state-of-the-art hydrofoils used on an offshore racing yacht in the prestigious Vendee Globe round-the-world race. Succeeded on the claim and defeated the counterclaim at a multi-week trial at the High Court, recovering a six-figure sum in damages and full costs recovery on account of a pre-action Part 36 settlement offer which was then beaten at trial. See judgment here.
- Acting for the fund managers of an offshore investment fund which held multi-billion-pound investments in the UK in a complex dispute relating to sums due under management agreements for a nationwide student accommodation portfolio. Settled the dispute, valued at several million pounds, at the pre-action stage which unlocked the ability for the fund managers to achieve a highly profitable disposal of the portfolio for more than £420 million.
- Acting for a high net worth individual in a dispute relating to overage provisions on a substantial residential property in a desirable suburb of Sheffield. Successfully contested the local council’s claim for an overage payment exceeding £1.5 million and settled on terms which provided for our client to pay less than 5% of the sum claimed.
Ciaran has been instructed on numerous disputes arising out of corporate transactions, advising upon and acting both in bringing and defending several multi-million pound claims relating to completion accounts, deferred consideration, warranties and fraudulent misrepresentation.
Recent Work
Acting for the former shareholders of a world-leading sports equipment manufacturer in defence of several breach of warranty claims and defective goods claims brought by the acquirer of the shares in a dispute worth over £1.5 million. Successfully defended the most valuable claims and settled the lower value claims at the pre-action stage on terms that were highly favourable to our client.
Acting for the former shareholders of a global logistics company in a dispute with the Australian purchaser of the shares over completion accounts in the share purchase agreement, defending claims valued at over £5 million. Settled a High Court claim on favourable terms for our clients.
Ciaran has acted in bringing and defending many claims relating to breaches of restrictive covenants and often-associated claims in breach of confidence or theft of confidential information, including advising on injunctive relief to prevent the use of confidential information.
Recent Work
- Acting for a market-leading accountancy practice in a series of claims which pursued and prosecute breaches of restrictive covenants by former employees, on every occasion successfully enforcing covenants and securing undertakings from the former employees regarding their future conduct.
- Acting for a heavy engineering company in a dispute relating to its former sale manager, who had taken confidential information to their new employer, a key competitor of our client. Quickly secured disclosure by the former employee of copies of all communications to our client’s customers and suppliers and written undertakings from the former employee regarding their future conduct.
- Advising several companies of amendments to restrictive covenants within their employment contracts and of amendments to company handbooks to protect the clients against former employees taking and using confidential information.
Ciaran regularly engages in alternative dispute resolution processes as a means of resolving matters early and avoiding the disruption, expense and exhaustion of court proceedings. Even where settlement can’t been reached through ADR, Ciaran recognises its value in narrowing issues and getting to the heart of a dispute, which makes it a useful tool in many disputes.
Recent Work
- Acting for a healthcare services provider and its Managing Director in defence of a multi-million-pound claim brought by several claimants in relation to a joint venture agreement. Represented our client at a mediation at an early stage of High Court proceedings at which the claim was settled on highly favourable terms, providing for the client to pay an amount less than 10% of the sum claimed.
- Acting for a charitable trust responsible for redeveloping an historical stately home of national importance in a wide-ranging and challenging dispute arising from a land and business sale agreement, which involved disputes over chattels/fixtures and abandonment (the Torts (Interference with Goods) Act 1977). Represented the charity at a mediation and negotiated a settlement which was hugely favourable in providing for title of chattels and other items to be transferred to the charity.
- Acting for an outdoor event logistics company at the mediation of a dispute relating to defective products, at which a non-monetary settlement was achieved which avoided any financial liability and enabled our client to preserve its commercial relationship and future business with the other party.

- Acting for a leading operator of retirement homes and its Managing Director in a matter in which a former employee’s partner had been harassing senior managers within the business. Succeeded in quickly obtaining written assurances from the individual that such conduct would cease.

- Acting for a minority shareholder and director of a healthcare supplies business in a dispute with the other shareholders and directors relating to allegations of breach of directors’ duties.
