Mediation Profile

Róisín is a founding Partner of ARC Mediation, founded in 2010, is the Chair of the Irish Professional Mediators’ Organisation CLG, and is a legal academic and qualified barrister.

Róisín has completed almost 600 mediations since 2009 including Family (Separation/Divorce), Work-place, Farm family, SME mediations, Founder Disputes, Commercial disputes, Succession disputes, Wards of Court and EPA (Enduring Power of Attorney) disputes and Personal Injury claims. Many of these cases have been referred to Róisín after legal proceedings have been initiated, and the majority of cases subsequently came to a mutually satisfactory agreement.

In recent years she is mediating international business and international family mediation cases.

She is a valued expert and legal academic and was awarded a Ph.D. in 2014 for her doctoral research on Judicial Separation and Divorce in the Circuit Court, Ireland. She continues to carry out academic research with a particular focus on mediation and civil justice systems and publishes regularly in peer reviewed journals/books and is a frequent guest presenter at seminars/conferences both nationally and internationally.

  • August 2023 – Róisín was appointed by University College Cork as an external panel member to the Programme Approval Panel for the LLM/PG Dip Mediation and Dispute Resolution
  • June 2023 Invited by Department of Justice to participate in the Family Justice Development Forum
  • June 2022 - June 2023: She and two fellow researchers, Dr Sinead Conneely and Dr Niamh Maguire, were awarded the tender by the Judicial Council's Sentencing Information and Guidelines Committee, 'SCIG', for a confidential research project. The research project titled 'Study of District Court Judges' views on Sentencing & Relationship Violence' forms part of the ongoing work of SGIC, who identified sentencing in the District Court as an area in need of study.
  • July 2021: She successfully completed the barrister-at-law degree at King’s Inns and was called to the Bar.
  • June 2020: Dr O’Shea was appointed by the Minister for Employment Affairs and Social Protection as a member of the Child Maintenance Review Group (2020-2022) chaired by former Circuit Court Judge Catherine Murphy. Róisín was a Director of the Mediators Institute of Ireland 2015-2021.
  • May 2019: She was appointed as an external independent evaluator for the revalidation of a Qualifications Ireland (QQI).

Róisín is the Principal Investigator for ‘The Family Mediation Project’ (2015-2023), trialing a family mediation process she developed, informed by global innovations, the final phase of which commenced in 2023. She and her colleague Dr Conneely carried out empirical research attending family law sittings with Ministerial consent in the District Courts in Ireland 2017-2019. She was invited by Government in 2019 to make an expert submission on the “Reform of the Family Law System” including the use of ADR.

Róisin has significant experience as a mediator completing almost 600 cases since 2009 including Family (divorce/separation), Work-place, Farm family, SME mediations, Commercial disputes, Succession disputes, Wards of Court and EPA (Enduring Power of Attorney) disputes and Personal Injury claims.  Her preferred model of mediation is co-mediation and is expert at managing multi-party disputes and disputes involving legal representatives, both on a national and international level.

Róisín's preferred mediation model is co-mediation and her mediation style is primarily facilitative, but she also uses transformative and evaluative (option development as provided in section 8 (4) of the Mediation Act 2017). She takes a pragmatic approach, assisting parties to find workable solutions, based on the facts and the needs of the parties. She ensures that the parties are well informed and receive legal advice where they intend the mediation settlement to be legally binding between them and in international cases assists the parties to agree where any agreement would be enforceable. Her practice ARC Mediation exclusively offers co-mediation and ensures that the mediators are a good fit in terms of competencies for the issues that are the subject of a dispute.

Róisín primarily works in the area of civil disputes; including Family mediation involving parenting, financial arrangements, legal separation and divorce (often inter-jurisdictional),  farm family and succession/probate disputes and inter-sibling disputes. She has mediated business disputes involving companies or partnerships, Founder disputes, contract disputes, workplace disputes, and personal injury disputes.
