Because a court treated a form combining debt acknowledgement with other transactions, whose hidden purpose was to extend limitation, as an unfair commercial practice and the acknowledgement itself as absolutely invalid for conflict with good morals. An acknowledgement of a time-barred debt also has effect only if the debtor knew it was time-barred. The consumer must therefore receive clear information about limitation and its consequences, preferably in the same document.
Acknowledgement without knowledge of limitation has no acknowledgement effect
Under the second sentence of Section 558 of the Civil Code, an act has the effects of acknowledging a time-barred debt only if the debtor knew it was time-barred. A creditor who has a consumer sign an acknowledgement of a time-barred claim without informing them about limitation therefore does not obtain what they thought they were obtaining.
The National Bank of Slovakia adds that if the creditor knows a claim may be time-barred, the documentation should pay particular attention to material information about the effects of limitation and debt acknowledgement. This information should be transparent, clear, comprehensible and unambiguous, preferably in the same document as the acknowledgement.
A consumer’s willingness to pay depends on understanding that the debt is time-barred. Withholding that information is therefore more than a formal defect: it interferes with their decision-making.
A form combining several transactions
The Slovak Supreme Court assessed an agreement on a form prepared in advance by the creditor that combined several legal relationships: a unilateral acknowledgement of an obligation, a declaration of knowledge about limitation and its consequences, an instalment agreement and an arbitration clause.
The court concluded that the agreement’s hidden purpose was to secure acknowledgement of the obligation and thereby extend limitation to ten years from acknowledgement. It assessed this as an unfair commercial practice, finding both lack of professional diligence by the supplier and a potential risk of distorting the consumer’s behaviour. In those circumstances, it considered the acknowledgement itself contrary to good morals and therefore absolutely invalid (Slovak Supreme Court decision of 30 May 2016, case No. 2MCdo/5/2015).
This underlies the National Bank of Slovakia’s recommendation: the act of debt acknowledgement should be distinguished within contractual documentation so there is no doubt that incorporating it into a broader document could have distorted the consumer’s behaviour to the point where they did not even appreciate the legal consequences. The NBS identifies placing the acknowledgement in a separate document as good practice.
A time-barred consumer contract right cannot be enforced
Under Section 54a of the Civil Code, a time-barred right arising from a consumer contract cannot be enforced. The explanatory memorandum describes this as enforcement through court, enforcement or arbitration proceedings, but it also affects the out-of-court stage.
The creditor is expected to exercise professional diligence in reliably determining whether the claim is time-barred, thereby avoiding warnings to consumers unsupported by applicable law. Supervisory authorities pay particular attention to out-of-court recovery of time-barred claims.
Practical implications
If you handle older consumer claims, settle three matters in advance: a reliable method for determining each claim’s limitation status; debt acknowledgement in a separate document with clear information about limitation and its consequences; and a separate instalment agreement so it cannot be interpreted as a device for obtaining acknowledgement.
