Dying without a will in Ireland

About one in five Irish adults dies without a valid will. Sometimes the omission is deliberate, sometimes it is simply that a will was never made or was lost. Either way, the consequences are identical: the estate is distributed not by the deceased's wishes but by the default rules set out in the Succession Act 1965. Those rules are clear, inflexible, and frequently at odds with what the family would have expected.

This page covers the intestacy rules in full, who applies for the Grant of Administration, and the situations where a solicitor is essential.

The short version

If someone dies without a will in Ireland, their estate passes under the rules in Part VI of the Succession Act 1965. The rules are rigid. Who inherits, and in what proportion, depends entirely on what relatives are still living.

In summary:

• Spouse only, no children. Spouse takes everything.
• Spouse and children. Spouse takes two-thirds, children share one-third equally.
• Children only, no spouse. Children share everything equally.
• Parents only, no spouse or children. Parents share everything equally (or sole parent takes all).
• Siblings only. Siblings share everything equally.
• Nieces and nephews only. Nieces and nephews share everything equally, per stirpes (by the share their deceased parent would have taken).
• Further relatives. Wider rules continue through the degrees of relationship.
• No relatives at all. The estate passes to the State as ownerless property.

Each of these produces outcomes that may or may not match what the family expected.

Spouse and children in detail

This is the most common intestacy case and the one most likely to produce surprises.

Under the Succession Act, a surviving spouse or civil partner with children takes two-thirds of the estate as of right. The remaining one-third is divided equally among the children. If any child has predeceased the parent leaving children of their own (grandchildren of the person who died), those grandchildren take their parent's share between them.

This is the rule that surprises families most often. A typical case: father dies leaving his wife and two adult children. The wife believed the house would pass to her alone. Under intestacy, two-thirds of the estate passes to her and one-third is split between the two children (one-sixth each).

If the house is the main asset, this can force a sale. The wife owns two-thirds, the children own one-sixth each, and the parties may disagree about whether to keep the house or sell it. In practice, most families negotiate a solution where the wife stays in the home and the children take their share in cash, but this requires willing cooperation. The statutory rule does not force that outcome; it forces the ownership split.

A will avoids the problem. A simple will leaving everything to the surviving spouse, with the children as substitutes if the spouse has died first, produces the outcome most couples expect.

Children only, no spouse

If there is no surviving spouse (either because the spouse died first or there was no spouse), the entire estate is divided equally among the children.

Adopted children are treated identically to natural children. Stepchildren are not included unless legally adopted. Children born outside marriage are treated identically to children born within marriage, provided the parentage can be established (typically via the birth certificate or a court declaration).

If a child has died before the parent but has children of their own, those grandchildren take their parent's share between them. This is the per stirpes rule and it operates automatically.

More distant relatives

If there is no surviving spouse, no children, and no grandchildren, the estate passes up the family tree under a fixed priority:

1. Parents share the estate equally. If only one parent survives, they take all.
2. If no parents, siblings share the estate equally. Half-siblings take the same share as full siblings. If a sibling has predeceased with children (nieces and nephews of the person who died), those nieces and nephews take their parent's share.
3. If no siblings or their descendants, nieces and nephews share the estate equally, per stirpes if any have died leaving their own children.
4. If none of the above, grandparents, then aunts and uncles, then first cousins, following the statutory priority.

The tests go out to several degrees of relationship before the estate becomes bona vacantia (ownerless property passing to the State). In practice, almost all estates find a living relative within the first three tiers.

Who applies for the Grant

A Grant of Administration is required to administer the estate. There is no executor because there is no will; the person who manages the estate is called an administrator.

The Rules of the Superior Courts set out who has priority to apply for the Grant. The order broadly mirrors the order of entitlement to inherit:

1. Surviving spouse or civil partner
2. Children (or grandchildren by representation)
3. Parents
4. Siblings (or nieces and nephews by representation)
5. More distant relatives in order

A person lower in the order can apply only if every person ahead of them has renounced their right to apply, or if the Probate Office is satisfied that higher-priority applicants cannot be located. Renunciations must be formal and in writing.

Evidence of entitlement

Unlike a probate application where the will identifies the executor, intestate applicants must prove their entitlement to apply. The Probate Office requires documentary evidence of the family relationship.

For a surviving spouse: original marriage certificate, plus the death certificate proving widowhood.

For a child: original birth certificate showing the person who died as a parent. Adopted children produce the adoption certificate.

For a parent, sibling, niece or nephew: a chain of birth and marriage certificates proving the relationship through the line of descent. This can get complex. A niece applying for her aunt's estate needs her own birth certificate, her parent's birth certificate (showing the parent and the aunt were siblings with common parents), and the aunt's birth certificate showing the same parents.

Missing or old certificates can take weeks to obtain from the General Register Office or from overseas registrars. Start this process early.

When intestacy is complicated

Intestacy cases that are genuinely simple (one surviving spouse, or one set of adult children, no disputes, all relatives known and traceable) are within the scope of a well-prepared personal applicant.

Intestacy cases that are not simple, and where a solicitor is the right call, include:

• Multiple marriages. Was the person divorced? Was the spouse a full legal spouse under Irish law or a cohabiting partner with no intestacy rights?
• Estranged children. Does a surviving child whose whereabouts are unknown need to be located and served notice?
• Children born outside marriage. Is parentage established on the birth certificate, or will a court declaration be needed?
• Children from a previous relationship. Are they entitled as children of the person who died even if they had limited contact?
• Blended families. Stepchildren have no automatic rights unless legally adopted. Is the distribution producing an unintended result?
• Overseas relatives. Are there siblings, nieces, or nephews living abroad who must be notified or located?
• Section 117 claims. A child who was not provided for adequately may have a separate claim, even where the strict intestacy rules do not allow for adjustment.

If any of these apply, the intestacy paperwork alone is a small fraction of the work. Locating people, resolving disputes, and potentially defending claims is the main cost. A solicitor is essential.

The planning message

Most families are better served by a straightforward will than by intestacy, even in apparently simple cases. A will that leaves everything to a surviving spouse with children as substitutes if the spouse has died first avoids the two-thirds / one-third split entirely. A will that names an executor avoids the administrator paperwork and makes the application 10 to 15% faster on average.

The cost of a simple will from an Irish solicitor is typically €100 to €300. The cost of intestacy, in both family friction and extra paperwork, is routinely several multiples of that. It is not ProbatePack's job to sell wills, but anyone reading this page who does not have one should consider making one.

For estates that have already landed in intestacy, the rules are what they are. The Preparation Pack handles the paperwork side; a solicitor handles the relationship side if that is where the complexity is.
