How to Verify the Authenticity of a Najem Okazjonalny Guarantee

Why verify the guarantee’s authenticity

Key traits of a genuine guarantee

• Document format. The guarantee must be in Polish and include the basics: guarantor details, address, signature.
• Owner’s signature. It should be original and consistent with register records.
• Property details. The address and ownership should be stated clearly and unambiguously.
• Issue date. The document should be current and aligned with the Najem Okazjonalny lease term.

How to check it yourself

1. Verify the address. Make sure the address exists and corresponds to a real property.
2. Confirm the owner. Ask the guarantor for proof of title (e.g., an extract from the Land and Mortgage Register).
3. Compare signatures. Match the signature on the guarantee with the one on the owner’s ID or other documents.
4. Ask a notary. If notarized, the notary can confirm the document’s authenticity.

Checks via official sources

For added certainty, use official databases:

• Land and Mortgage Register (Księgi Wieczyste). The online service lets you verify the property owner.
• Notarial acts registers. If the document was notarized, you can locate it in the official register or confirm with the notary who drew it up.
