Does a Change of Registered Address Affect a Najem Okazjonalny Lease

Does a change of registered address affect a Najem Okazjonalny

In a Najem Okazjonalny package, one mandatory attachment is a guarantee naming the address to which the tenant will move if the lease is terminated. A natural question follows: if the tenant or guarantor changes their residence registration, does this affect the legal force of the package?

Why the address in the guarantee matters

The indicated address is the landlord’s assurance that, in case of breach, there is a destination for move-out. The notary checks this address and attaches it to the file. If it’s not current, the fast-track eviction mechanism may be weakened.

When a change of registration affects the lease

• If the registration matches the guarantee address. Changing registration means a new guarantee is required.
• If the guarantor changes registration. The old address becomes outdated — an updated guarantee is needed.
• If you used the “address to be added later” variant. If registration changes before the address is filled in, provide the new address.

When a change of registration does not affect it

• If the tenant’s registration differs from the guarantee address (the guarantee points to another property).
• If the guarantor’s new registration does not change the dwelling’s availability (e.g., an admin update within the same building).
• If the package was already executed before a notary and both parties uphold the previously indicated address and the dwelling remains available.

What to do after a registration change

1. Notify the landlord. Do it promptly.
2. Prepare a new guarantee. The guarantor issues a document with the updated address.
3. Notarise if required. If notarisation was required before, the new guarantee should also be notarised.
4. Keep both versions. Retain the old and new guarantees for your records.

Risks of ignoring the change

• The package may be ineffective for the streamlined eviction process.
• The landlord may refuse to extend the lease.
• In court, the tenant’s position may be weaker.

Tips for tenants

• On any change of registration, check whether a new guarantee is needed.
• Make changes formally — avoid verbal arrangements.
• Ensure the notary works with the updated data.

Tips for landlords

• Monitor that the guarantee address stays current.
• Request a new document when registration changes.
• Record all changes in writing and keep copies.
