Meet the Team

I’m Sinéad Costello, and my core expertise lies in Probate, Wills and Estate Planning. With extensive experience in this area, I guide clients through the administration of estates and help families plan for the future with clarity, structure and confidence.

I have been appointed as a Notary Public by the Chief Justice of Ireland, a role that reflects both professional trust and long-standing experience. I have also completed the Personal Insolvency Practitioner Course and hold a Certificate in Assisted Decision-Making Capacity (ADMC Act) from the Law Society of Ireland.

Whether you need advice on planning your estate, navigating the administration process or understanding your options for the future, I’m here to help.
