High Court Strikes Cavan Solicitor Ronan O'Brien Off the Roll

In a significant regulatory ruling delivered at the High Court, former practitioner Ronan O'Brien has been formally struck off the Roll of Solicitors. The order was made on 11 June 2026 by the President of the High Court following an application brought by the Law Society of Ireland under Section 85 of the Legal Services Regulation Act 2015. The proceedings, registered under High Court record 2026 No. 42 SA, follow extensive disciplinary findings relating to the severe mishandling of client funds and regulatory breaches at his practice in County Cavan.

Mr O'Brien, who previously practised under the title of Ronan O'Brien & Company Solicitors at 69 Church Street, Cavan, was the subject of an inquiry before the Legal Practitioners Disciplinary Tribunal. On 14 October 2025, the Tribunal concluded under record reference 2024-LPDT12 that the practitioner was guilty of misconduct across multiple grounds. The determination substantiated systemic failings in the maintenance of client moneys, unauthorised withdrawals, and direct breaches of statutory accounting regulations governing the legal profession in Ireland.

Misappropriation of Client Funds and Property Transactions

Central to the Tribunal's findings was the misappropriation of €239,500 from a client ledger account. This substantial sum was diverted to partly finance two property transactions located in Cavan, specifically the premises at 69 Church Street for Mr O'Brien himself, and 37 Connolly Street on behalf of his client, Drumesta Limited. The improper use of these funds was formally admitted by Mr O'Brien in a replying affidavit sworn on 13 May 2024 during the course of the disciplinary process.

The Tribunal's inquiry further revealed that this initial diversion formed part of a wider pattern of unauthorised financial actions. An unauthorised payment executed on 30 November 2022 resulted in a direct deficit of €239,500 on a client file. In a separate incident on 21 December 2023, Mr O'Brien made an unauthorised payment of €22,500 on his own behalf, precipitating a deficit of that exact amount on another client reference.

Widespread Deficits and Accounting Failures

The disciplinary findings detailed several additional instances where client accounts were placed in deficit through unauthorized transactions. On 27 September 2023, an unauthorised payment led to a €6,150 deficit on the client ledger of a deceased person's estate. In another matter, on 3 March 2023, an unauthorised payment generated a debit balance of €10,000 on a client reference at a time when no client moneys were being held to the credit of that client.

The Tribunal also identified substantial breaches in respect of internal accounting standards and regulatory transparency. On 8 April 2024, a transfer of €105,750 was made from the client account to the firm's office account without suitable vouching documentation. The Tribunal found that Mr O'Brien failed to maintain proper books of account and essential supporting records, rendering client moneys incapable of being duly vouched and recorded in accordance with professional obligations.

Breaches of Statutory Regulations and High Court Sanctions

The collective conduct was determined to be in direct breach of both the Solicitors Accounts Regulations 2014 and the updated Solicitors Accounts Regulations 2023. These statutory frameworks impose rigorous safeguards on legal practitioners to ensure client funds remain entirely segregated and protected from firm operations. Additionally, the Tribunal established that Mr O'Brien failed to document requisite client risk assessments across seven separate client references, in breach of the Money Laundering and Terrorist Financing Regulations 2020.

Following these findings, the President of the High Court granted the Law Society's application to remove Mr O'Brien from the profession. Under Section 85(7)(f) of the Legal Services Regulation Act 2015, the court ordered that his name be struck off the Roll of Solicitors. Under Section 85(7)(h)(iii), the respondent was ordered to pay €10,114.50 to cover the Law Society's costs incurred during the Tribunal proceedings. Pursuant to Section 85(8), the High Court also ordered Mr O'Brien to pay forthwith the measured costs of the High Court application itself, which were fixed at €3,978.
