Tenant Documents for Life Changes in Poland

GDPR: data protection & tenant documents 2 min read · published September 11, 2025
A change in life circumstances — for example the birth of a child, divorce, job loss or moving — can affect entitlement to allowances and a tenant's obligations in Poland. This guide explains which documents are worth preparing: the tenancy agreement, proof of residence, income certificates, official decisions and evidence of incurred costs and repairs. We also explain how to protect tenant personal data according to GDPR, how to organize evidence and where to submit applications for benefits or information to the municipality. The goal is to help tenants react efficiently and maintain legal security when life circumstances change.

The documents collected below will help when applying for allowances and resolving matters with the landlord.
