Limitation in medical liability claims – deadlines, late effects & what you need to know

If you suspect a treatment error, your first question is whether there was an error at all. Just as important, but easier to overlook, is time: claims for damages in medical liability cases become time-barred. If you wait too long, you can lose an otherwise valid claim – however clear the error was. This page explains calmly and without jargon which time limits apply in Austria, when they start to run, how to protect claims for late effects and what to do if your claim is about to become time-barred.

The time limits: three years and thirty years (§ 1489 ABGB)

§ 1489 ABGB governs the limitation of claims for damages. Two time limits apply side by side:

• Three years from knowledge – the short period starts to run as soon as the injured party knows of both the damage and the identity of the person who caused it. Both conditions must be met.
• Thirty years from the event – regardless of any knowledge, the claim becomes time-barred no later than 30 years after the event that caused the damage, that is, after the faulty treatment. This absolute limit protects against claims being brought after a very long time.

In practice, it is almost always the short three-year period that matters. It runs out faster than many people expect – and it requires the injured party to act promptly as soon as it becomes apparent that there may have been a treatment error.

When ‘knowledge’ begins – the most important and most difficult point

The three-year period does not start as soon as something has gone wrong or symptoms appear. It only starts once the injured party knows enough about the facts to bring a claim with a prospect of success. This requires knowledge of the damage, of the person who caused it and of the causal link – that is, knowledge that the damage results from a treatment error.

In medical liability cases, this point is particularly delicate. A poor outcome after an operation is not necessarily recognisable as the result of an error – it can just as well be the result of a treatment risk that has materialised. Often, only a medical expert report or a specialist second opinion makes it clear that the treatment was faulty at all. Under the case law, the period therefore often only begins in such cases when the patient actually knew of the treatment error and its causal link with the damage, or could have recognised them by making reasonable enquiries – not at the first suspicion.

Important: if you have indications of an error, you cannot wait as long as you like. Case law requires you to make reasonable enquiries. If you remain inactive despite specific grounds for suspicion, the period can start to run even without final certainty. Because the start of the period can be highly disputed in an individual case, never assess it on your own – have a lawyer clarify it.

Protecting claims for late effects: action for a declaratory judgment under § 228 ZPO

Late effects are a particular problem. Some damage only becomes apparent years after the treatment or cannot yet be quantified today – for example a progressive impairment or permanent damage that only becomes recognisable later. If you waited until the damage had run its full course, the claim would risk becoming time-barred.

This is where an action for a declaratory judgment under § 228 ZPO helps. While the period is still running, it allows you to obtain a court ruling that the treating doctor or hospital is liable for future damage from the treatment error that cannot yet be quantified. This has a twofold effect: the claim for future damage remains open as to its amount, and the limitation period is interrupted. Once the declaratory judgment becomes final, a new, long period generally runs for the claims it covers. This means you do not have to put a figure on every euro today, and yet future claims are not lost through the passage of time. The action for a declaratory judgment is therefore a key tool, particularly in serious or unclear cases.

Why you should not wait

Even if the time limit has not yet expired, there are many reasons not to wait. Over time, the evidence usually becomes weaker:

• Memories fade. After several years, it is almost impossible to reconstruct conversations about risks and the information you were given.
• Records become incomplete. Test results, notes and witnesses are easier to get hold of early on than later.
• The start of the period becomes unclear. The longer you wait, the more likely a dispute becomes about when ‘knowledge’ existed – a risk you avoid by acting early.

In medical liability cases, the burden of proof generally lies with the patient, and the proceedings rest on a report by a court-appointed medical expert. Securing the complete medical records early is therefore one of the most important steps of all.

What to do if your claim is about to become time-barred

If the end of the period is approaching and a final assessment is not yet possible, there are ways to secure the claim instead of letting it lapse:

• Waiver of the limitation defence / standstill agreement: You can agree a time-limited waiver of the limitation defence with the liability insurer or the hospital operator. This buys time for the review.
• File a claim or an action for a declaratory judgment in time: Filing the claim interrupts the limitation period. For damage that cannot yet be quantified, you file an action for a declaratory judgment under § 228 ZPO.
• Get a lawyer’s assessment quickly: A few weeks can be decisive. An early review clarifies which step will stop the limitation period running.

How we help

We start with the time-critical question: when did the period begin, and how much time is left? We request the medical records and make a realistic assessment of when the period started. If the deadline is about to expire, we secure your claims – for example with an action for a declaratory judgment or a waiver of the limitation defence. We tell you honestly if a course of action has little prospect of success. If the period may already have expired, we tell you that just as clearly.
