The Alternative Premises Owner's Declaration – Template and Requirements
October 6, 2026
What is the alternative premises owner's declaration?
The alternative premises owner's declaration is a document in which a person holding legal title to another dwelling consents to the tenant — together with the people living with them — residing there if the obligation to vacate the rented premises is ever enforced. Alongside the tenant's notarial declaration and the tenant's indication of the address, it is the third mandatory attachment to an occasional tenancy agreement.
Without this document, the occasional tenancy agreement — even if all other requirements are met — will not be fully effective. It is precisely the owner's consent that gives a bailiff somewhere to move the tenant to, if they do not voluntarily leave the apartment once the tenancy ends.
Legal basis
This requirement follows directly from Article 19a(2)(3) of the Act of 21 June 2001 on the Protection of Tenants' Rights, Municipal Housing Resources, and Amendment of the Civil Code. The provision requires attaching to the agreement a declaration from the owner of the premises (or a person holding legal title to it) consenting to the tenant and the people living with them residing in the premises indicated in the declaration referred to in point 2 of the same article — that is, in the tenant's indication of the alternative premises.
The Act also provides that, at the landlord's request, the alternative premises owner may be asked to provide a notarially certified signature — but this is the exception, not the rule. As a general rule, a plain written form is enough.
What the alternative premises owner's declaration must contain (requirements)
So the document does not raise doubts with the landlord, or later at the stage of granting the enforcement clause, it should include:
- the alternative premises owner's details — name and identifying information (or the company name and details, if the owner is a legal entity),
- confirmation of legal title to the premises — ownership, cooperative right, or sometimes a tenancy with a right to sublet — together with the basis of that title (e.g. a land register number),
- the exact address of the alternative premises — street, building and unit number, city,
- a reference to the specific occasional tenancy agreement — the parties (landlord and tenant) and the date it was concluded,
- a clear and irrevocable consent for the tenant and the people living with them to reside in the alternative premises if enforcement takes place,
- the period for which the consent is granted — usually tied to how long the owner holds legal title to the premises,
- the date and the owner's signature — a plain written form is enough, unless the landlord has requested notarial certification.
Missing any of these elements does not automatically invalidate the occasional tenancy agreement, but it may lead a court to refuse to grant the enforcement clause at the enforcement stage — which undermines the whole point of occasional tenancy.
Two different documents that are easy to mix up
The alternative premises owner's declaration is not the same thing as the tenant's indication of another premises, referred to in Article 19a(2)(2) of the Act. These are two separate documents, drawn up by two different people:
- The indication of the alternative premises — drawn up and signed by the tenant. It tells everyone which address the tenant will move to.
- The alternative premises owner's declaration — drawn up and signed by the owner of the indicated premises. It confirms that they actually agree to take the tenant in.
Both documents must match — the address given by the tenant must be the same address to which the owner consents. Here is what a sample tenant's indication of the alternative premises looks like:
| Document element | What it contains |
|---|---|
| Heading | "Indication by the Tenant of another premises in which they will be able to reside in the event of enforcement of the obligation to vacate the Premises" |
| Date and tenant details | Place and date drawn up, name(s) of the tenant(s) |
| Legal basis | Reference to Article 19a(2)(2) of the Act on the Protection of Tenants' Rights of 21 June 2001 |
| Content of the declaration | Indication of the rented premises' address and a declaration that, in the event of enforcement, the tenant will reside in the alternative premises |
| Alternative premises address | The exact address and the details of the owner the tenant will move to |
| Signature | A legible signature of the tenant (or of all tenants, if the agreement covers several people) |
Why you need both documents together
An address indicated by the tenant alone means nothing without the consent of that premises' owner. If a tenant could simply "indicate" someone else's apartment without the owner's knowledge, a bailiff still would have no grounds to move anyone there. That is why the Act requires both documents together — the tenant's indication of the address and the owner's consent to that address. Only the complete set of these two declarations, together with the tenancy agreement and the notarial submission to enforcement, forms a full, effective occasional tenancy package.
How this works with us: two ready-made documents in one order
Most tenants get stuck right at this point — they have an occasional tenancy agreement ready to sign, but no one willing to lend them an address and sign the alternative premises owner's declaration. That is why we offer an address-provision service for occasional tenancy, through which you receive from us a complete set of two documents, not just one:
- The tenant's declaration indicating another premises — prepared and filled in with the data from your order (your name, the landlord's details, the date the agreement was concluded, and the alternative premises address), ready for you to sign,
- The alternative premises owner's declaration of consent to residence — already signed on behalf of our company, confirming consent for you and the people living with you to reside in the indicated premises.
You receive both documents by email together with your order confirmation, in PDF and Word format, ready to attach to your occasional tenancy agreement straight away. You do not need to look for the owner of another apartment yourself, or worry about whether the declaration contains all the required elements — we prepare them in line with the requirements of Article 19a of the Act on the Protection of Tenants' Rights.
Does the owner's declaration need to be notarized?
No. Just like the tenant's indication of the premises, the alternative premises owner's declaration only needs a plain written form. A notary is needed for only one element of occasional tenancy — the tenant's declaration of submission to enforcement. We cover this in more detail in our article Does the Alternative Address for Occasional Tenancy Need to Be Notarized?
Frequently Asked Questions
Does the alternative premises owner's declaration have an expiry date?
Yes, the consent is usually granted for as long as the owner themselves holds legal title to the premises (e.g. until their own tenancy agreement ends, or until a specific date). It is worth checking this before concluding the occasional tenancy agreement, so the consent covers the whole planned tenancy period.
Does the alternative premises owner need to be related to the tenant?
No, the Act does not require any kinship or other special relationship. The alternative premises owner can be any person or entity holding legal title to the premises — including a company providing this kind of service commercially.
What if the alternative premises owner changes their mind?
The consent given in the declaration is, by its own terms, irrevocable for the whole period for which it was granted. This is one of the elements that should, in practice, appear in the document's content, to protect both the tenant and the landlord against a situation where the alternative premises "disappears" during the term of the agreement.
Can I get both documents separately, without ordering the whole package?
As part of a single order, we prepare the complete set of both documents straight away — the tenant's indication of the premises and the owner's consent — so nothing needs to be filled in by hand or chased up separately.
Summary
The alternative premises owner's declaration is a mandatory, if often overlooked, third pillar of occasional tenancy — alongside the notarial declaration and the tenant's indication of the address. It does not require a notary, but it must precisely identify the owner, the premises, and the scope of the consent. If you have no one to ask for such a declaration, order the complete set of two documents from us — the indication of the premises and the owner's consent — ready to sign alongside your occasional tenancy agreement.
