Founder of Keogan Law & Tax, Aileen Keogan, has been advising clients since 1993. Aileen set up her own practice in 2009 originally as Aileen Keogan Solicitor & Tax Consultant to provide private clients with specialist succession planning combining both legal and taxation advice. Previously developing her speciality area in Ireland’s leading law firms, A&L Goodbody and McCann FitzGerald, and the boutique tax firm Warren & Partners, Aileen has over 30 years’ experience advising clients on complex succession planning issues. Her particular areas of expertise are trusts and taxation issues including cross border matters.

A key feature of Aileen’s service is her willingness where required to collaborate closely with her clients’ other advisers. This ensures an integrated approach to meeting the specific needs of the client. As a respected thought leader in the area, Aileen works with general practice solicitors, accountants and professional advisers to support their clients. She complements their work with her deep knowledge of complex probate, trust, capital taxation, estate planning and succession issues.
