Adverse Possession in Ireland: How Three Brothers Secured 34 Acres in Co Galway
Published April 28, 2026
In a landmark ruling that underscores the complexities of Irish property law, three brothers—Fergal, Pat, and Aonghus Hassett—have been granted legal ownership of 34 acres of land in Co Galway through adverse possession. The decision, handed down by the Circuit Court, resolves a decades-long dispute with their cousin, Claire Keegan, and highlights how long-term occupation can override formal inheritance claims under Irish law.
This case serves as a critical example of how adverse possession—often colloquially referred to as “squatter’s rights”—can reshape property ownership in Ireland. For landowners, heirs, and legal professionals, the ruling offers key insights into the requirements for claiming title through occupation, the role of wills in such disputes, and the potential pitfalls of unchallenged land use.
The Case: A Family Dispute Over 34 Acres
The land in question, located at Tiernascragh in southeast Co Galway, consists of two parcels: one spanning 22 acres and another 12 acres. The dispute traces back to Thomas Keegan, who was registered as the full owner of the property in 1906. Thomas married Margaret Keegan (née Nevin), a widow with two sons from her first marriage, Patrick and John Bohan. Together, they had eight children, including Allan Keegan, the eldest.
Following Thomas Keegan’s death in 1956 (intestate, meaning without a will), his wife inherited a one-third share of the land, while their seven surviving children each received a one-seventh share of the remaining two-thirds. Margaret later died in 1963, leaving all her property—including her share of the Tiernascragh land—to her son John Bohan via her will.
Fast-forward to 1999, when Allan Keegan drafted a will leaving the 34 acres to his three nephews: Fergal, Pat, and Aonghus Hassett. Though, Allan did not formally transfer the land during his lifetime. After his death in 2002, the brothers sought to register their ownership with Táilte Éireann (Ireland’s land registration authority), but their application was initially refused. Their cousin, Claire Keegan, who had been using the land to graze horses, contested their claim but did not participate in the subsequent appeal proceedings.
The Legal Battle: Adverse Possession vs. Inheritance Rights
The brothers’ case hinged on adverse possession, a legal principle that allows a person to claim ownership of land if they have occupied it continuously, openly, and without the owner’s permission for a specified period—in Ireland, typically 12 years for registered land. In his ruling, Judge Gerard Meehan determined that the Hassett brothers had met these criteria, entitling them to be registered as the legal owners.
Key factors in the court’s decision included:
- Continuous Occupation: The brothers demonstrated uninterrupted use of the land for the required period.
- Exclusive Control: Their occupation was not shared with or challenged by the legal owner (Claire Keegan) in a timely manner.
- Acts of Ownership: They performed actions consistent with ownership, such as maintaining the land and excluding others.
The ruling underscores a critical nuance in Irish property law: a will alone does not guarantee ownership. Without formal registration or transfer during the owner’s lifetime, heirs may find their claims contested, particularly if another party has occupied the land under adverse possession rules.
What Is Adverse Possession?
Adverse possession is a legal doctrine that allows a person to claim ownership of land if they have occupied it for a statutory period without the permission of the registered owner. In Ireland, the requirements for a successful claim include:
- Actual Possession: The claimant must physically occupy the land, using it as an owner would (e.g., farming, building, or maintaining it).
- Open and Notorious: The occupation must be visible and obvious, not hidden or secretive.
- Exclusive and Continuous: The claimant must use the land without sharing control with the legal owner for the full statutory period (12 years for registered land in Ireland).
- Hostile Possession: The occupation must be without the owner’s consent. This does not imply ill will but simply that the owner has not granted permission.
Under the Registration of Title Act 1964 and the Statute of Limitations 1957, adverse possession can extinguish the original owner’s right to reclaim the land if they fail to take legal action within the prescribed timeframe. Once the statutory period elapses, the occupier can apply to Táilte Éireann to be registered as the novel owner.
How Adverse Possession Differs from Inheritance
While inheritance is the legal transfer of property upon the owner’s death (typically via a will or intestacy rules), adverse possession is a possessory claim that can override inheritance rights if the following conditions are met:
| Aspect | Inheritance | Adverse Possession |
|---|---|---|
| Basis of Claim | Legal right derived from a will or intestacy laws. | Long-term, uninterrupted occupation of the land. |
| Timeframe | Immediate upon the owner’s death (subject to probate). | Requires 12+ years of continuous occupation (for registered land). |
| Registration | Requires formal transfer via probate or deed. | Requires application to Táilte Éireann or court adjudication. |
| Owner’s Rights | Heirs have a legal claim unless contested. | Original owner’s rights are extinguished after the statutory period. |
Why This Case Matters for Landowners and Heirs
The Hassett brothers’ victory is a cautionary tale for landowners and potential heirs. Key takeaways include:
1. The Importance of Formal Registration
A will alone is not enough to secure ownership of land. Heirs must ensure that property is formally transferred and registered in their names. In this case, Allan Keegan’s will left the land to his nephews, but without a deed of transfer or registration, their claim was vulnerable to challenge.
2. The Risks of Unchallenged Occupation
Claire Keegan’s use of the land for grazing horses was not sufficient to establish adverse possession, but her failure to actively contest the brothers’ claim weakened her position. Landowners must monitor their property and take legal action if they suspect unauthorized occupation.
3. The Role of Táilte Éireann
Táilte Éireann plays a critical role in adjudicating adverse possession claims. Applications must include detailed evidence of occupation, such as:
- Affidavits from witnesses attesting to the claimant’s use of the land.
- Photographic or documentary proof of occupation (e.g., fencing, farming records, utility bills).
- Evidence that the legal owner was aware of the occupation and did not object.
If Táilte Éireann has doubts about a claim, it may require court adjudication, as was the case here.
4. Family Disputes and Adverse Possession
Adverse possession claims often arise in family disputes, particularly where land has been informally used by relatives over generations. The Hassett case is a prime example of how inheritance and occupation rights can collide, leading to protracted legal battles.

How to Protect Your Land from Adverse Possession Claims
For landowners concerned about adverse possession, the following steps can help safeguard their property:
1. Regularly Inspect Your Property
Conduct periodic inspections to ensure no unauthorized parties are occupying the land. Early detection allows for timely legal action.
2. Document Ownership and Use
Maintain records of property taxes, utility bills, and any leases or licenses granted to others. This documentation can serve as evidence of active ownership.
3. Grant Licenses, Not Possession
If you allow someone to use your land (e.g., for grazing or farming), grant a license rather than a lease. A license does not confer possession and can be revoked at any time, reducing the risk of an adverse possession claim.
4. Take Legal Action Promptly
If you discover unauthorized occupation, consult a solicitor immediately. Under Irish law, the 12-year clock for adverse possession starts when the owner becomes aware of the occupation and does not act. Filing an eviction notice or initiating legal proceedings can reset this timeline.
5. Update Your Will and Register Transfers
Ensure your will is up to date and that any land transfers are formally registered with Táilte Éireann. This reduces the risk of disputes among heirs and strengthens their claims against third-party occupiers.
Frequently Asked Questions About Adverse Possession in Ireland
Q: How long must someone occupy land to claim adverse possession in Ireland?
A: For registered land, the statutory period is 12 years. For unregistered land, the period is likewise 12 years, but the claimant must apply for first registration with Táilte Éireann.
Q: Can adverse possession apply to residential property?
A: Yes, but it is less common. Adverse possession claims typically involve agricultural or undeveloped land where occupation is easier to establish. However, cases involving residential properties do occur, particularly in disputes over boundaries or abandoned homes.
Q: What happens if the legal owner objects to an adverse possession claim?
A: If the legal owner contests the claim, Táilte Éireann may refer the matter to court. The court will examine evidence of occupation, the owner’s awareness, and whether the occupation was truly “adverse” (i.e., without permission).
Q: Can a tenant claim adverse possession against a landlord?
A: Generally, no. Tenants occupy land with the landlord’s permission, which negates the “hostile” requirement for adverse possession. However, if a tenant remains in possession after the lease expires and the landlord takes no action, a claim may arise.
Q: Is adverse possession the same as squatting?
A: While the terms are often used interchangeably, squatting typically refers to the illegal occupation of vacant or abandoned property, whereas adverse possession is a legal process that can lead to ownership if the statutory requirements are met. Squatting alone does not guarantee a successful adverse possession claim.
The Future of Adverse Possession in Ireland
The Hassett brothers’ case has reignited debates about the fairness of adverse possession laws in Ireland. Critics argue that the current system can lead to unfair outcomes, particularly in family disputes where heirs may lose land to relatives who have occupied it for years. Some legal scholars, such as Una Woods in her 2025 paper published in the Irish Judicial Studies Journal, have called for reforms to introduce a “qualified veto” for registered owners, allowing them to block adverse possession claims even after the statutory period has elapsed.
Proponents of the current system, however, argue that adverse possession serves a valuable purpose by ensuring land is used productively. In cases where the legal owner has abandoned or neglected the property, adverse possession can facilitate its transfer to someone who will maintain and develop it.
For now, the law remains unchanged, and landowners must remain vigilant. As Judge Meehan’s ruling demonstrates, the line between inheritance and occupation is not always clear-cut—and in Ireland, possession can indeed be nine-tenths of the law.
