Guarantor Statement Mistakes and How to Avoid Them

The most common mistakes in the guarantor statement for a Najem Okazjonalny lease: inaccurate data, missing signature, wrong address. Tips to avoid them.

Guarantor Statement Mistakes and How to Avoid Them

The guarantor statement is a key document in a Najem Okazjonalny lease — without it, the lease loses its effect. It confirms the address to which the tenant agrees to relocate if the lease is terminated and underpins the landlord’s legal protection. However, it’s often prepared with errors that render the document invalid or seriously complicate eviction. This article lists the most common mistakes and how to avoid them.

Most common mistakes in the guarantor statement

ErrorConsequencesHow to avoid
Incorrect personal details (name, PESEL, address)The document may be deemed invalidDouble-check all details before submission
No specific address indicatedThe tenant is not formally obliged to move outProvide the full address with postcode and flat number
Missing owner’s signatureThe document loses legal forceEnsure all required signatures are in place
Using an outdated templateRisk that a notary refuses to accept the documentUse current forms from a notary or trusted services
Errors in dates or termsUncertainty about the lease’s validity periodSpecify exact dates and verify their accuracy
No notarial certification (when required)Possible refusal to accept/record the leaseConfirm certification requirements with the notary

Frequent causes of mistakes

  • DIY drafting without advice. People often use incomplete online templates.
  • Haste. Date and data errors usually stem from rushing.
  • Language barrier. Non-Polish speakers make translation mistakes.
  • No prior notary check. Documents arrive to the notary already flawed, delaying signing.

Tips for preparing the guarantor statement correctly

  1. Use up-to-date forms and reliable templates only.
  2. Verify all details before filing: full name, ID, PESEL, address.
  3. Always state the complete move-out address, not just city or street.
  4. Collect all signatures on original documents in time.
  5. When in doubt, consult a notary or lawyer.

Example: incorrect vs correct guarantor statement

IncorrectCorrect
Address: “Warszawa”Address: “ul. Marszałkowska 10/5, 00-001 Warszawa”
Signature of tenant onlySignatures of the property owner + tenant
Date: “2023”Date: “15.05.2023”

Conclusion

Errors in the guarantor statement can make the lease unenforceable and cause serious eviction issues. To avoid trouble, carefully verify all details, use current forms, and prepare documents through a notary or trusted providers. The guarantor statement is not “just an annex” — it is a cornerstone of your legal safety.
