Validity Period of a Najem Okazjonalny Guarantee in Poland

We explain how the validity period of a guarantee is determined, what happens after it expires, how to renew the document, and the risks of failing to renew on time.

What is the validity period of a guarantee

In a Najem Okazjonalny agreement, the guarantee is a document in which the owner of another dwelling confirms readiness to accept the tenant if the lease is terminated. A key element of this document is its validity period, which determines its legal effect and whether it can be relied upon in a dispute.

How the validity period is determined

The law does not set a fixed validity period for the guarantee. It is usually tied to the term of the Najem Okazjonalny lease itself. For example, if the lease is for one year, the guarantee is issued for the same period. When the lease is extended, the guarantee should be renewed to keep it current.

What happens after the period ends

Once the guarantee expires, it loses legal force. In this situation:

  • The landlord cannot use the document to pursue an expedited eviction procedure.
  • The tenant loses evidence supporting the transparency of their obligations.
  • A notary, when preparing new agreements, will require a current guarantee.

Potential risks

The main risk is that the parties forget to renew the guarantee when they extend the lease. As a result, the landlord is left without legal protection and the tenant faces legal uncertainty.

How to renew the guarantee properly

To avoid problems, it is recommended to:

  • Align the guarantee period with the term of the Najem Okazjonalny lease.
  • Track expiry dates and prepare the renewal in advance.
  • Update the guarantee at the same time as the lease extension.
  • Keep originals and copies for possible checks or court proceedings.

Frequently asked questions

Can the guarantee be issued “without a term”?

No. It should always be linked to a specific period corresponding to the Najem Okazjonalny lease.

Do I need a new guarantee every year?

Yes. If the lease is extended, the guarantee should be renewed for the new term.

Who is responsible for monitoring the validity period?

Both parties — the landlord and the tenant — share responsibility. A notary will also check the document’s validity when the lease is extended.

Conclusion

The guarantee’s validity period directly tracks the Najem Okazjonalny lease and should be renewed at each extension. Both parties must ensure the document remains current to preserve legal protection.
