Contamination at a judicial auction property: remediation duties and bidder risk

A contamination warning is first a reason to establish the facts. Former use, a documented deposit, a published area, actual contamination and a concrete danger to soil or water must be distinguished. These terms do not have the same legal or economic meaning.

The information position in a judicial auction adds another difficulty. A valuation report may describe soil or use only to a defined extent. Check which areas were examined, which period the information concerns and whether the present condition differs from it.

Section 18(4) ALSAG provides for the publication on the contaminated-sites portal of certain old deposits, former operating sites and contaminated sites. This includes areas where a significant contamination or significant risk is expected after an initial assessment, areas assessed under the statutory procedure and designated contaminated sites. Save the search for the specific plot number or address.

Since 1 January 2025 there has been no public search of a suspected-sites register. The portal also states that an empty map does not prove that no old deposit or former operating site exists at the location. The area search on the contaminated-sites portal is therefore an important part of the review, not a clearance certificate.

Section 3 ALSAG regulates the contaminated-sites contribution. It covers, among other things, depositing waste and certain forms of placing, storing, filling or adapting land with waste. This can become economically relevant during later earthworks or when contaminated material is handled.

Section 3 ALSAG does not automatically mean that the purchaser must remediate or that a particular area is contaminated. Contribution liability, environmental danger prevention, remediation measures and allocation of costs are separate questions. They should not be reduced to one undifferentiated risk figure.

Section 31 WRG requires persons whose facilities, measures or omissions may affect waters to take the necessary care to prevent pollution not covered by a water-law permit. If a danger nevertheless arises, appropriate immediate measures must be taken and the district administrative authority must be informed.

For a purchaser, not every historical soil irregularity automatically creates a personal water-law duty. The relevant facts include the cause, knowledge, danger, previous measures and the particular rules of succession. Section 31(4) WRG also addresses the landowner and successors in defined cases where they knew or should have known of the facilities or measures causing the danger.

Record at least four figures separately: the stated valuation, known investigation or safety costs, possible remediation or disposal costs and your personal bidding limit. A portal entry does not provide a reliable euro amount for remediation.

Also assess whether access, financing, later use and resale may be made more difficult by the uncertainty. The article on the court valuation report helps compare the inspection date, property description and attachments. The environmental questions still require their own assessment beside that review.

In a judicial auction, section 189(2) EO excludes a warranty claim based on incorrect statements in the edict or in the files supplied before the auction concerning the property or its accessories. Open contamination questions should therefore be classified before bidding using the available documents and actual conditions.

This does not make authority information unnecessary. It means that assumptions about clean soil, safe use or low follow-up costs should not be treated as assured properties. Read also the article on bidder risk without warranty and the review of the auction conditions before bidding.
