- The basics are the land register number and the acquisition document.
- You need certificates from the owners' association or cooperative and on registered residents.
- Since 2023 an energy performance certificate has been required for a sale.
One missing certificate can delay the notarial deed by several weeks. That is why I gather the documents at the very start, before the listing reaches buyers. Below is a list of the documents most often needed. The notary always confirms the final set.
An apartment with its own land register (separate ownership)
- the land register number,
- the acquisition document: a notarial deed, a deed of gift, a court decision confirming inheritance or a notarial certificate of inheritance,
- a certificate from the property manager or owners' association confirming there are no arrears,
- a certificate of the persons registered as resident at the property (or that there are none),
- an energy performance certificate.
Cooperative ownership right to a unit
- a certificate from the cooperative confirming the right, no arrears and the land register number (if one exists),
- the other documents as above.
An apartment with a mortgage
- a bank statement of the outstanding balance and the account number for repayment,
- the bank's undertaking or consent to remove the mortgage after repayment.
Taxes: what to remember
If you sell within five years of the end of the year in which you acquired the property, as a rule you pay 19% income tax on the gain from the sale. One exemption is spending the proceeds on your own housing needs within a set period (the so-called housing relief). On the resale market, the civil law transactions tax (PCC) is usually paid by the buyer.
As of October 2026. Tax rules change, so check the details of your situation with a notary or tax adviser.
