why does the insurer ask if my company owns real estate

Real estate on the balance sheet is risk assessment, not liability

An insurer usually asks this for risk assessment in connection with a business damage or liability insurance policy, not as client due diligence under the Wwft. Ownership of a business premises entails a different risk profile than leasing: fire damage to an owned property directly affects the balance sheet of the insured, whereas in the case of leasing, the landlord often bears the building risk and the tenant only insures inventory or business damage. The question is therefore related to the coverage being requested, and not to an assessment of the enterprise as a whole — other questions are used for that, such as those about the average payment term to suppliers or the financial health of the company.

If the enterprise does not own real estate, "no" is the answer — that is not a problem, it only determines which policy terms apply. If the enterprise does own a property, it is often asked about the year of construction, use and sometimes the WOZ value or rebuilding value; these data are usually not in the supply chain file because they do not come from a legal register, but from the enterprise's own administration or valuation.

Where this comes from and where it does not come from

Ownership of real estate is not information that the Trade Register Act 2007 records about an enterprise, nor is it part of client due diligence under the Anti-Money Laundering and Counter-Terrorist Financing Act, which focuses on identity and ultimate beneficial owners — see also the question about who are the ultimate beneficial owners of the company. The question stems from the insurer's own acceptance policy when determining premium and coverage. The supply chain file therefore contains no source for this, and the system does not suggest an answer here until the enterprise provides it itself.
