In short: the question occasional lease or standard lease comes down to one thing: an occasional lease and a standard tenancy agreement give you exactly the same grounds for termination — they only differ in what happens if the tenant still refuses to move out. The right choice depends on who you're renting to and how much you're willing to invest upfront in security.
Formal differences — comparison
| Feature | Occasional lease | Standard lease |
|---|---|---|
| Form of agreement | Written, void if not in writing | Written recommended, no such requirement |
| Required attachments | 3 declarations, including a notarial deed | None |
| Tax office filing | Mandatory, within 14 days of tenancy start | No obligation |
| Upfront cost | Notary fee — a few hundred zloty | PLN 0 |
| Who can be the landlord | Only a private individual not renting as a business | Any landlord |
| If the tenant doesn't move out | Enforcement clause on the notarial deed + bailiff, no court | Eviction lawsuit, court ruling, then a bailiff |
| Time to recover the property in a dispute | Weeks to months | Realistically a year or more |
When a standard lease is more than enough
If you're renting to family, friends, or someone you know well and have vetted over time, the extra paperwork of an occasional lease rarely pays off. The same goes for short-term, low-risk arrangements — the cost and time spent on a notary visit aren't always justified if you assess the risk of conflict as low.
When it's worth investing in an occasional lease
An occasional lease pays off most where the risk is real: renting to someone found through a listing, with no prior relationship, for a longer fixed term, at a higher rent or property value, or simply after a bad experience with a tenant who refused to leave. In these situations, the faster path to recovering the property has real value — it works like an insurance policy you buy once, upfront.
Weigh the cost against the risk, not on its own
A few hundred zloty for a notarial declaration looks like an expense — until you compare it with the alternative: a years-long eviction process isn't just court fees and possibly a lawyer, but above all months or years without rent from a property you can't legally hand over to someone else. A one-off notary fee then looks like cheap insurance, not an extra cost.
Can a tenant refuse to sign the notarial declaration?
Yes, they can — and it's your call what to do next. Without that declaration you can't conclude an occasional lease with that particular person; you're left with a standard lease. A refusal itself can also be a signal worth weighing when evaluating a prospective tenant.
Occasional lease pros and cons at a glance
Pros: a faster path to recovering the property without a court eviction process, real leverage with a problematic tenant, the same protection as a standard lease while it's in force.
Cons: extra paperwork upfront (notarial deed, three attachments), a mandatory tax-office filing within 14 days, the risk that a prospective tenant refuses to sign the declaration and you have to look for someone else.
One more practical caveat: with a tenant from abroad the second attachment — naming another property to move out to — is often impossible to satisfy, which quietly removes the whole advantage of this form. The workarounds are described in the article on the letting to a tenant from abroad.
Frequently asked questions
Can I convert a standard lease into an occasional one while it's running?
Yes, but in practice that means a new occasional lease agreement (or an amendment adding the missing elements) — you'll need all three attachments, including the notarial deed, and a tax-office filing within 14 days.
Is an occasional lease more expensive for the tenant?
The rent itself isn't — the amount doesn't depend on the form of the agreement. The tenant usually covers the cost of the notarial declaration, which is capped by law.
Can I use an occasional lease when renting to a company?
The statutory restriction applies to the landlord — they must be a private individual not running a rental business. There's no equivalent restriction on the tenant's side, but in practice an occasional lease is used when renting to individuals for housing purposes.
