Suspension of Limitation Periods and Mediation

A frequently cited advantage of mediation in Austria is that mediation suspends the statute of limitations - that the clock effectively stops, allowing parties to pursue mediation or commercial mediation without losing time. This assumption, however, is only partly correct. Misunderstandings that do not withstand legal scrutiny may lead to significant risks, particularly in high-stake disputes arising from business transactions and liability matters.

This article examines the circumstances under which limitation periods are in fact suspended through mediation under Austrian law, how this mechanism should be understood from a legal perspective, and what parties must observe in practice to safeguard their rights.

Understanding the Suspension of Limitation Periods in Austria

Once a contractual or statutory claim arises, parties have only a limited timeframe to assert that claim in court or arbitration. After the limitation period expires, the claim can no longer be legally enforced.

If parties enter into negotiations while the limitation period continues to run, there is a risk that the claim becomes time-barred before a resolution is reached. In extreme cases, negotiations may even be prolonged until enforcement is no longer possible.

To address this risk in the context of mediation and commercial mediation, Austrian law provides for the suspension of limitation periods. Where the statutory requirements are met, the limitation period does not continue to run during the mediation. The running of time is effectively paused for the duration of the mediation process.

The practical benefit is clear: parties gain the time necessary to work towards solutions without having to initiate court or arbitration proceedings merely to preserve their claims or to negotiate a separate agreement on tolling the limitation period.

However, several key parameters require careful attention.

Suspension vs. Prevention of Expiry: A Vital Distinction

Austrian law distinguishes between different mechanisms that affect limitation periods. In the context of mediation, it is essential to differentiate between a suspension of the limitation period (Fortlaufshemmung) and situations in which the expiry of the limitation period is merely prevented (Ablaufshemmung).

• In the case of a suspension, the duration of the mediation is excluded from the calculation of the limitation period. Put simply, a pause button is pressed. The clock resumes only once the suspension ends (e.g. after the termination of mediation proceedings).
• In contrast, the limitation period continues to run, if only the expiry of the limitation period is prevented. Once the preventing event ceases to apply, the party must assert the claim within a reasonable period. According to prevailing legal doctrine and case law, this period is often estimated at around three months, thus there is not a fixed statutory grace period.

Failing to distinguish between these two mechanisms may lead to a serious miscalculation of the time remaining to assert a claim.

Requirements for Statutory Suspension (Fortlaufshemmung)

Statutory suspension applies only if the mediation falls within the scope of the Austrian Civil Mediation Act (ZivMediatG). According to Section 22 ZivMediatG, the limitation period is suspended upon the commencement of mediation, provided that specific statutory requirements are met.

• The dispute must be of a civil-law nature, meaning a conflict that could in principle be resolved before a state court or an arbitral tribunal. This includes contractual disputes between companies, shareholder disputes and other commercial conflicts arising from B2B relationships.
• The process must be conducted by a mediator, who is registered on the list of the Austrian Federal Ministry of Justice.
• The process must be expressly agreed upon and conducted as a formal mediation and the scope of the mediation must be clear. Informal discussions, facilitated negotiations or mere settlement talks do not suffice.
• The mediation must be duly continued within an appropriate timeframe.

If these requirements are not met - for example if the process is facilitated by a non-registered mediator or consists merely of settlement discussions - Section 22 ZivMediatG does not apply. In such cases merely the expiry of the limitation period is prevented.

Practical Advice for Safeguarding Claims in Commercial Mediation

Against this legal background, several practical issues deserve particular attention where limitation periods may be economically material.

Which Legal Mechanism Applies?

Assume a mediation lasts for six months and, at the outset, six months remain before the limitation period expires. If the mediation fails, it makes a critical difference whether a suspension or merely a prevention of expiry is applicable.

Where statutory suspension applies, the limitation period is paused for the duration of the mediation. After the mediation ends, the remaining six months are still available to initiate court or arbitration proceedings.

Where only prevention of expiry applies, the situation is considerably tighter. Following the end of the process, only a reasonable grace period remains – often estimated at around three months – to file a claim.

For companies and in-house legal teams, it is therefore strategically essential to assess (i) whether the mediation falls within the scope of ZivMediatG, (ii) whether its statutory requirements are fulfilled, and (iii) which form of staying the limitation mechanism follows in the specific case.

The applicability of the ZivMediatG cannot always be determined conclusively at the outset. In practice, processes often fall into a grey area between mediation, facilitation and settlement negotiations. For this reason, particular attention should be paid to the mandate and assignment of the mediator.

When Does the Suspension Begin?

The point in time at which mediation commences is legally relevant, as it marks the beginning of the suspension. According to section 17 ZivMediatG, mediation is deemed to commence once the parties agree to address their dispute by way of mediation. This may coincide with the conclusion of a written mediation agreement, but it does not necessarily do so. An earlier oral agreement may suffice (provided it can be substantiated).

Because this starting point is not always clear-cut, precise contemporaneous documentation is essential.

How Can Parties Ensure That the Suspension Continues?

Initiating mediation alone is not sufficient. For limitation periods to remain suspended, the mediation must be duly continued within an appropriate timeframe.

This requires active engagement in the process, ongoing mediation activity, visible procedural progress and cooperation by all parties involved. If the process effectively comes to a standstill for a prolonged period, the suspension ends and the limitation period resumes.

When Do Limitation Periods Resume?

Limitation periods resume once the mediation is no longer duly continued or has come to an end. This may occur when the parties reach a full or partial settlement, when one or more parties terminate the process because no agreement appears achievable, or when the mediator terminates the proceedings and resigns.

What matters is the point in time at which the mediation effectively ends, whether through an express declaration or through factual inactivity. For reasons of legal certainty, this point should be clearly documented.

Which Claims are Covered?

The suspension of limitation periods applies only to legal relationships between the parties to the mediation. Claims involving third parties are not affected.

This distinction is particularly relevant in complex commercial settings, such as multi-party contracts, corporate group structures or ongoing business relationships. Participation in mediation with one party does not automatically suspend limitation periods vis-à-vis other contractual partners.

Who is Responsible for Documenting Evidence for the Suspension?

As a general rule, the mediator is required to document the commencement, course and termination of the mediation, as well as the circumstances relevant to whether the mediation was duly continued (Section 17 ZivMediatG).

This documentation must be retained for at least seven years after the end of the mediation and made available to the parties upon request.

Regardless of this obligation, responsibility for monitoring limitation periods ultimately remains with the parties themselves. Particularly in commercially significant matters, parties are well advised to keep their own records of all relevant dates and procedural steps.

Takeaway

The suspension of limitation periods through mediation is clearly regulated under Austrian law, but it is subject to defined conditions. It does not apply automatically and requires a structured and well-documented process.

Where commercially relevant claims are at stake, mediation should therefore be understood not as a substitute for legal risk management, but as part of a legally coordinated dispute resolution strategy (in more detail here).
