Seller Verification

Due Diligence·Updated 27 Jun 2026·8 min·Confidence: High

How to verify a seller, company and communication pattern before trusting the transaction.

Seller KRS NIP

Identity

The seller profile must match records, property title and invoice issuer. A company seller requires NIP, KRS and signatory authority.

Key takeaway. This section is designed as an operational reference, not a motivational note. Every claim should eventually map to a document, observation or calculation.

Communication pattern

Piotr responded quickly, provided structured explanations and did not aggressively pressure. This improved trust but did not replace verification.

Company footprint

Domy pod Gwiazdami Sp. z o.o. had a website, NIP and visible property activity. The website did not look ultra-corporate, but it was consistent with a small operator.

Red flags

Refusal to provide documents, changed bank accounts, pressure to pay before checks, unclear ownership or hostility toward notary questions are major red flags.
