TL;DR · WeSearch summary

The article discusses the importance of accessing the Krajowy Rejestr Sądowy (KRS) directly via API for accurate corporate data in Poland. It highlights the risks associated with relying on outdated data from global aggregators, which can lead to misinformed decisions during mergers and acquisitions. The KRS provides a transparent and legally binding record of company structures and changes, essential for compliance and due diligence.

Key facts

▪The KRS records significant corporate changes that are legally binding once entered into the court register.
▪Using a direct API link to the KRS is crucial to avoid acting on outdated information during pre-acquisition checks.
▪Polish corporate data includes essential identifiers and capital structure details, which are vital for accurate cross-checking.
