Decision-Making Representative Ireland: The Capacity Act and What It Means for Estates

If you are currently managing the affairs of a parent or family member who is losing capacity — or if someone close to you has recently died after a period of cognitive decline — Ireland's Assisted Decision-Making (Capacity) Act 2015 is directly relevant to your situation. The Act introduced a new legal framework for supporting people with diminished capacity, and it has significant implications for how estates are managed and what happens when the person eventually dies.

What the Assisted Decision-Making (Capacity) Act 2015 Changed

Before this Act came into force, Ireland's capacity law was built around the Wards of Court system — an archaic Victorian-era mechanism where a court could declare a person of "unsound mind" and place their entire affairs under judicial control. The system was widely criticised as paternalistic and inflexible.

The Assisted Decision-Making (Capacity) Act replaced the Wards of Court system with a graduated framework that starts from the presumption that every adult has capacity, and provides progressively more structured support only when needed. The Decision Support Service (DSS) was established to administer the system.

The transition is ongoing. Existing Wards of Court are being reviewed and their wardship orders replaced with appropriate arrangements under the new Act. The process is expected to complete by 2027.

The Three Tiers of Decision Support

The Act creates three distinct support structures, each suited to different levels of need.

Decision-Making Assistance Agreement The least restrictive option. A person who has capacity but wants help understanding complex decisions can appoint a Decision-Making Assistant. The assistant helps gather information and explains options, but the person retains full decision-making authority.

Co-Decision-Making Agreement Where a person's capacity fluctuates or is diminishing, they can appoint a Co-Decision-Maker who shares decision-making authority in specified areas — typically financial or personal welfare decisions. Both parties must agree before any decision is made. The agreement is registered with the Decision Support Service.

Decision-Making Representative Order Where a person lacks the capacity to appoint a support arrangement themselves, a family member or other appropriate person can apply to the Circuit Court or High Court to be appointed as a Decision-Making Representative (DMR). This is a court-ordered appointment. The DMR makes specified decisions on behalf of the person, within the scope defined by the court order.

The DMR is the closest equivalent to the old committee of a Ward of Court, but it is more focused in scope and subject to greater oversight by the Decision Support Service.

When a DMR's Authority Ends

This is the point that catches families off guard. A Decision-Making Representative's legal authority ends immediately and automatically upon the death of the person they are supporting. There is no grace period, no wind-down period, and no requirement for a court order to terminate it.

From the moment of death, the DMR cannot make any further decisions about the deceased's affairs. They cannot continue to operate bank accounts, pay outstanding bills, manage property, or access any assets — even if they have been doing so for years with full legal authority. Any actions taken after death under the guise of the DMR role are legally void.

The same rule applies to Enduring Powers of Attorney (EPAs) registered with the Decision Support Service. An EPA that was validly created and registered during the donor's lifetime is automatically revoked upon their death.

All legal authority shifts entirely to whoever holds the right to administer the estate: the executor named in the will, or the administrator appointed under a Grant of Letters of Administration if there is no will.

The Transition From DMR to Executor

For families where the deceased was subject to a Decision-Making Representative arrangement, the transition period between death and the appointment of an executor (or administrator) creates a legal gap. No one has legal authority to act.

This matters practically because:

• Bank accounts that the DMR was managing cannot be accessed.
• Bills that were being paid from the deceased's accounts must temporarily stop.
• Property management decisions cannot be made.
• Third parties who were receiving instructions from the DMR must be notified that the authority has ceased.

If the deceased left a will, the named executor steps into this role — but an executor only has formal legal authority to act after obtaining the Grant of Probate from the Courts Service. In the interim, the executor has some informal authority to take protective actions (securing the property, notifying institutions), but cannot distribute assets or make binding commitments on behalf of the estate.

In practice, the most important immediate actions are to locate the will, confirm who is the named executor, notify all institutions that were dealing with the DMR that the arrangement has ended, and begin the process of obtaining death certificates.

Enduring Powers of Attorney and the New EPA Framework

The Assisted Decision-Making (Capacity) Act introduced a new form of Enduring Power of Attorney to replace the old-style EPAs created under the Powers of Attorney Act 1996. New EPAs under the Act must be created using specific prescribed forms, registered with the Decision Support Service, and activated by a statement from a capacity assessor if the donor's capacity is in question.

Old-style EPAs created before the Act's commencement remain valid. However, their authority — whether old or new format — terminates at the point of death.

Families managing the estates of people who had an active EPA should ensure that all financial institutions, property managers, and utility companies are notified of the termination of the EPA promptly after death.

Pre-Death Estate Planning: What the Capacity Act Makes Possible

For caregivers supporting a parent who still has capacity, the Act creates tools that can significantly simplify future estate administration.

A Co-Decision-Making Agreement in the financial domain, set up while the parent still has capacity, can help ensure all accounts and assets are documented, accessible, and understood by the person who will likely administer the estate later. This reduces the risk of hidden or forgotten accounts appearing long after the estate has been distributed.

The Act also reinforces the importance of a well-structured Enduring Power of Attorney — one that clearly documents the extent of the donor's assets and financial arrangements — which directly prepares the ground for a smoother estate administration.

If the parent's capacity is declining and they have not yet made a will or EPA, this is an urgent situation. A solicitor can assess whether the person still has sufficient testamentary capacity to execute a valid will. Once capacity is lost, making a new will becomes legally impossible and the estate will pass under the rules of intestacy.

What This Means for Estates Currently in Administration

If you are currently acting as executor of an estate where the deceased was under a DMR arrangement or had an active EPA, you should:

1. Confirm in writing to all institutions that the DMR/EPA terminated at the date of death.
2. Request that your authority as executor is substituted in all ongoing correspondence.
3. Obtain the Grant of Probate before attempting to access or transfer any assets.
4. Review the Decision Support Service's records to understand the scope of any decisions made by the DMR during the administration period — particularly regarding property or financial transactions that will need to be accounted for in the Revenue SA.2 Statement of Affairs.

The intersection of the capacity framework and estate administration is one of the less-understood aspects of Irish succession law — and one where errors carry genuine legal risk.

The When Someone Dies in Ireland — Estate Settlement Guide covers the complete estate administration sequence, including how the executor's authority interacts with pre-existing capacity arrangements, the DSP notifications required at death, and the full Revenue and Probate Office process. If you are managing an estate that has passed through a period of capacity-related support, the guide provides the procedural roadmap from the date of death through to final distribution.
