Finian is Head of the Dispute Resolution team at Thomas Mansfield Solicitors.

He advises on commercial, civil and employment disputes, including breach of contract, agency and professional negligence claims. He has typically represented companies, partnerships and individuals in disputes with larger enterprises.

Finian also advises executors, trustees and beneficiaries on contentious private client and probate matters, and landlords and property owners on property disputes.

Finian takes care to understand a client’s objectives before deciding whether the interest of the client is best served through litigation in the Courts or through alternative dispute resolution techniques such as mediation. His approach is to resolve disputes pragmatically and at an early stage wherever possible.

Prior to qualifying as a solicitor in 2013, Finian worked for fourteen years as a newspaper journalist on regional and national titles in London, Manchester and Dublin. He studied Modern History at Oxford University as an undergraduate and obtained a distinction in his Legal Practice Certificate from the College of Law in London.
