A duty of care is a legal obligation to take the care required in a particular relationship or situation. In an ordinary negligence claim in Ireland, an injured person must establish more than an accident: a duty owed to them, a failure to meet the required standard, a causal link to the injury, and resulting harm. The rules differ between workplaces, roads, premises and healthcare.
This guide explains those distinctions and the evidence that can help answer them. It concerns personal injury claims in the Republic of Ireland.
What does duty of care mean in Irish law?
The starting point is the relationship and the law governing it. An employer’s responsibility for a system of work differs from a shop operator’s responsibility for the condition of its premises. Identifying who was responsible, and for what, comes before deciding whether they fell short.
Foreseeable harm matters, but foreseeability alone does not create every legal duty. Existing legal authority, the relationship between the parties and the scope of any relevant legislation matter too. The High Court’s discussion of Barlow in AB v An Taoiseach [2026] IEHC 236, paragraph 185 explains why the familiar duty-of-care factors should not be treated as a universal test.
What are the four parts of a negligence claim?
People sometimes call these the “four principles of duty of care”. More accurately, they are four questions about a negligence claim; they do not all concern whether a duty exists.
- Duty: Did this person or organisation owe you a relevant legal obligation?
- Breach: Did their conduct fall below the standard required in those circumstances?
- Causation: Did that failure cause or contribute to the injury for which you seek compensation?
- Damage: What injury and associated losses resulted?
A duty can exist without a breach. A breach can occur without causing the particular injury alleged. These distinctions underpin the Law Reform Commission’s explanation of negligence in Chapter 3 of its 2009 report.
How does the duty change in different settings?
At work
Under section 8 of the Safety, Health and Welfare at Work Act 2005, an employer must protect employees’ safety, health and welfare so far as reasonably practicable. Its duties include safe systems of work, suitable equipment, and necessary information, training and supervision.
For an employee injured while lifting, the investigation might examine the task assigned, available lifting aids, instructions and staffing. A signed training sheet is one piece of evidence; the actual arrangements on the day also need examination. Our accidents at work guide explains the wider claim process.
On the road
Section 52 of the Road Traffic Act 1961 prohibits driving in a public place without due care and attention. That criminal provision does not itself answer every question in a civil injury claim. Evidence about position, speed, visibility and what each road user did helps establish how a collision happened. See our road traffic accident claims guide.
In a shop, building or outdoor space
The Occupiers’ Liability Act 1995 focuses on control over premises and the danger concerned. The responsible occupier is not necessarily the legal owner, and more than one person may have relevant control.
For visitors, section 3 requires reasonable care in the circumstances. Its amended wording expressly considers the likelihood and seriousness of injury, the practicality and cost of precautions, and relevant social utility. It also considers the care reasonably expected of the visitor.
Different rules ordinarily apply to recreational users and trespassers, with an important exception concerning certain recreational structures. A warning sign is not automatically enough: section 5 addresses whether it enables a visitor to avoid injury. Voluntarily accepted risks can also affect liability.
During medical treatment
Clinical negligence requires assessment against the relevant professional standard. In its 2020 Annual Report, pages 102–103, the Supreme Court explains the Morrissey decision and the role of expert evidence in establishing the standard expected of a comparable professional. An adverse outcome alone does not establish negligent treatment. The alleged failure and its effect on the patient’s injury both require investigation. Our medical negligence guide addresses this separate area.
Which evidence helps prove each part?
Organise records around the questions they answer. This also helps distinguish something you witnessed from an explanation suggested afterwards.
| Question | Useful material to identify or preserve | What still needs checking |
|---|---|---|
| Who was responsible? | Employer details, business names, location, relevant instructions and correspondence. | Which person or organisation controlled the task, premises or activity? |
| What allegedly went wrong? | Photographs, witness details, incident reports, available CCTV and relevant maintenance or inspection records. | What reasonable precaution was allegedly missing, and what was happening before the incident? |
| How did it cause injury? | Your account of the sequence, medical records, symptom history and appropriate expert evidence. | Does the evidence connect the alleged failure with the injury, rather than just show both occurred? |
| What loss followed? | Receipts, treatment expenses, earnings records and a factual note of practical restrictions. | Which losses relate to this injury, and what documents support the amount? |
Irish court pleadings require particulars of the alleged wrong, injuries and special damage under section 10 of the Civil Liability and Courts Act 2004. Keeping a clear record early can make those particulars easier to establish. The personal injury evidence guide gives further practical detail.
What is an example of a possible breach?
Hypothetical example: a customer slips beside a leaking refrigerator. A photograph of the puddle helps record the condition. The investigation would still ask who controlled the area, how long the leak had existed, what inspections or precautions were reasonable, and whether that puddle caused the fall.
A medical report may support the injury, but it does not by itself establish the condition of the floor. Equally, identifying a leak does not prove that every later symptom resulted from the fall. This is an illustration of the questions to investigate, not a prediction of a claim’s outcome.
What if you were partly at fault?
Your own contribution does not necessarily defeat a claim. Under section 34 of the Civil Liability Act 1961, damages may be reduced where your lack of reasonable care contributed to the damage alongside another person’s wrong. The reduction reflects responsibility; it is not automatically 50%. See our guide to contributory negligence in Ireland.
What should you do after an injury?
Get appropriate medical attention, record the incident accurately and keep the records already available to you. Identify any CCTV promptly and ask that relevant footage be preserved. Do not guess at missing details: note what you know and what remains uncertain.
Check the applicable claim deadline promptly rather than waiting for every document. The correct process depends on the type of claim. A discussion with a personal injury solicitor can establish which duty applies, what evidence is missing and whether the facts support a claim.
