What Documents Are Needed to Buy Property in Greece in 2026? Full Process From Decision to Registration at the Hellenic Cadastre

Buying property in Greece is not only a simple agreement between a buyer and a seller. It is a legal, technical, tax, and registration process.

In 2026, many parts of the process are digital.

The notary can use the Digital Property Transfer File through gov.g. At the same time,e the Real Estate Transfer Tax declaration can be submitted through myPROPERTY, the digital platform of AADE (Independent Authority for Public Revenue in Greece).

At the end of the process, the deed must be registered with the Hellenic Cadastre, known in Greek as Ktimatologio.

The Ktimatologio is the official national land registry system that records property rights, ownership, cadastral codes, and registered deeds in Greece.

This guide explains the full process in simple language, from the moment a buyer decides to purchase a property to the moment it is registered in the new owner’s name.

1. Decision to Buy and First Property Check

First, the buyer chooses the property and agrees on the basic commercial terms with the seller. These usually include the price, the payment method, and the estimated signing date.

However, the buyer should not rush to pay a deposit before the basic checks. In Greece, a property may look attractive, but it may still have legal, technical,l or tax issues.

At this stage, the buyer should check:

• whether the seller is the legal owner,
• whether the property has mortgages, liens, seizures, or other burdens,
• whether the square meters match the title deed, tax record,s and technical documents,
• whether the property has unauthorized constructions,
• whether the property is correctly recorded in the Ktimatologio,
• whether the seller can collect all required documents.

For this reason, the buyer should involve three key professionals early on: a lawyer, a civil engineer, and a notary.

---

2. Legal Check by a Lawyer

Next, the buyer’s lawyer checks the ownership titles. This legal check usually takes place at the competent Ktimatologio office or, in some areas, at the older Mortgage Registry system, known in Greek as Ypothikofylakeio. The Ypothikofylakeio is the traditional land and mortgage registry that still operates in some areas where the cadastral system has not fully replaced it.

The lawyer checks:

• the seller’s title deed,
• the chain of previous title deeds,
• mortgages or pre-notations,
• claims by third parties,
• pending legal or cadastral issues,
• the KAEK number,
• the correct property description.

KAEK means Cadastral Registration Number. It is the unique identification number of a property inside the Greek Cadastre system. For foreign buyers, this number is very important because it connects the legal deed with the official cadastral record.

The legal check protects the buyer from serious risks. For example, a property may be priced well but still have an old mortgage, an inheritance issue, or an incorrect cadastral record.

Therefore, the buyer should seek a clear legal opinion before proceeding.

3. Technical Check by a Civil Engineer

At the same time, the civil engineer checks the real condition of the property.

The engineer compares the actual property with the building permit, floor plans, square meters, and any previous legalization documents.

The engineer checks:

• whether the property has unauthorized constructions,
• whether older unauthorized works have been legalized,
• whether the square meters are correct,
• whether a new topographic diagram is needed,
• whether an Energy Performance Certificate is required,
• whether the Electronic Building Identity can be issued or updated.

The Electronic Building Identity, known in Greek as Ilektroniki Taftotita Ktiriou, is a digital technical file for the property. It records the building permit, plans, legalizations, surface areas, and the property’s technical status. Through gov.gr, users can access the Register of Building Identities, which is connected with the Technical Chamber of Greece.

For most property transfers, the seller needs a valid Electronic Building Identity or Electronic Identity of Independent Property. A qualified engineer prepares it.

If the engineer finds a serious issue, the buyer should not ignore it. The seller must usually resolve the issue before the notarial deed is executed.

---

4. Documents Collected by the Seller

After the first legal and technical checks, the seller starts collecting the required documents.

The notary confirms exactly which documents are needed for each case.

A typical file includes:

• seller’s title deed,
• ENFIA certificate,
• tax clearance certificate or debt certificate,
• social security clearance certificate, where required,
• TAP certificate from the municipality,
• Electronic Building Identity,
• Energy Performance Certificate, where required,
• topographic diagram, where required,
• cadastral sheet,
• cadastral diagram,
• ID card or passport,
• Greek tax number,
• tax office details.

ENFIA means Unified Property Ownership Tax. It is the annual property tax in Greece. The ENFIA certificate confirms that the property has been correctly declared for tax purposes in the previous years.

TAP means Municipal Real Estate Duty. It is a small municipal property tax associated with the property, usually assessed before a sale.

The notary may also request extra documents. For example, a property inherited by the seller may need inheritance documents. A property with co-owners may need documents from all owners. A property with a bank burden may need additional bank documents.

---

5. ENFIA Certificate

The ENFIA certificate is one of the most important tax documents for a property transfer in Greece.

With this certificate, the seller proves that the property appears correctly in the seller’s tax records for the required previous years. If the certificate contains incorrect details, the transfer may be delayed.

The notary usually checks whether the ENFIA certificate matches:

• the title deed,
• the property surface,
• the floor,
• the ownership percentage,
• the use of the property,
• the cadastral record.

If there is an error, the seller’s accountant must correct the E9 before the transaction proceeds.

E9 is the Greek electronic property declaration form.

Every property owner in Greece uses E9 to declare real estate assets to the tax authority.

The E9 data affects ENFIA and must align with the real property status as closely as possible.

AADE provides digital services for E9 and ENFIA.

---

6. TAP Certificate From the Municipality

The seller may also need a TAP certificate from the local municipality.

TAP, or Municipal Real Estate Duty, is connected with the municipality where the property is located. The certificate usually confirms that there are no unpaid municipal property duties for the specific property.

In practice, the municipality may ask for:

• a recent electricity bill,
• property details,
• title deed,
• owner details,
• application form.

This step can delay the sale if the municipality has a backlog or if the property details do not match the municipal records.

Therefore, the seller should start this process early.

---

7. Tax Clearance and Social Security Clearance

In addition, the seller must usually provide a tax clearance certificate.

If the seller has no tax debts, the process is simple. If the seller has tax debts, the transfer may continue in some cases. The tax authority may issue a debt certificate, and the notary may withhold part of the purchase price to pay the debt.

AADE provides electronic services for real estate transfer tax declarations and related property tax procedures through myPROPERTY. In a notarial sale, the notary completes the tax return, and the contracting parties accept it digitally.

In some cases, the seller may also need social security clearance. This may apply when the seller has certain professional or insurance obligations in Greece.

For foreign buyers, this is important because a seller’s debt can delay the execution of the notarial deed. The notary and lawyer should check this before the signing date.

---

8. Real Estate Transfer Tax Through myPROPERTY

Before the notarial deed is signed, the Real Estate Transfer Tax declaration must be submitted.

The Real Estate Transfer Tax, known in Greek as Foros Metavivasis Akinitou (FMA), is the tax paid when real estate is transferred for consideration. In a standard sale, the buyer is responsible for paying this tax. gov.gr states that the real estate transfer tax is imposed on the property’s value and that the buyer is liable for payment.

The declaration is submitted through myPROPERTY, the AADE digital platform for property tax declarations. AADE explains that when a notarial deed is drawn up, the notary completes the real estate transfer tax return and submits it or has it accepted by the contracting parties.

The usual process is:

1. The notary prepares the tax declaration.
2. The buyer and seller check the details.
3. The parties accept the declaration digitally.
4. AADE issues the tax assessment, where tax is due.
5. The buyer pays the tax.
6. The notary proceeds with the final deed.

The buyer should not treat this as a simple formality. The tax declaration must match the property details, the agreed price, and the official taxable value.

---

9. First Home Tax Exemption

If the buyer purchases a first home in Greece, they may qualify for a first-home tax exemption.

This is known in Greek as apallagi protis katoikias. It means an exemption from the real estate transfer tax for the purchase of a primary residence, subject to specific legal conditions. gov.gr provides information about the exemption from real estate transfer tax for the purchase of a primary residence.

The buyer should check:

• family status,
• existing property ownership,
• property value,
• property size,
• residence requirements,
• documents required by the notary.

However, the buyer should not assume automatic eligibility. The notary and accountant must confirm it before the tax declaration is finalized.

This is especially important for foreign buyers, Greek expatriates, and buyers who already own property in Greece or abroad.

---

10. Digital Property Transfer File

In 2026, the notary may use the Digital Property Transfer File, known in Greek as Psifiakos Fakelos Metavivasis Akinitou.

This is a digital file that helps organize the transfer of registered properties. On gov.gr, buyers, sellers, and notaries can complete the transfer process online for property sales.

In practice:

1. The notary starts the digital transfer file.
2. The seller logs in to the platform and selects the property.
3. The buyer accepts the invitation.
4. The notary gathers the required documents.
5. The tax declaration is completed.
6. The deed is signed.
7. The deed is submitted for registration.

The Digital Property Transfer File does not replace legal and technical due diligence.

It only helps the process move faster and more efficiently.

Therefore, the buyer should still use a lawyer and an engineer before signing.

---

11. Draft Notarial Deed and Final Review

Before signing, the notary prepares the draft deed.

The notarial deed, known in Greek as symvolaio, is the official legal document that transfers ownership from the seller to the buyer.

The buyer and the buyer’s lawyer should review the draft carefully.

They should check:

• the agreed price,
• payment method,
• seller details,
• buyer details,
• property description,
• KAEK number,
• square meters,
• floor,
• ownership percentage,
• storage room or parking space,
• rights attached to the property,
• debts withheld from the price,
• special terms.

For example, if the apartment includes a parking space or storage room, the deed must clearly state whether these are separate properties or accessory rights.

This detail matters because it affects ownership, future resale, and tax declarations.

---

12. Signing the Deed

After all checks and documents are ready, the buyer and seller sign the notarial deed.

The buyer usually pays the price through the banking system. This creates clear proof of payment. The buyer should avoid unclear payment methods, especially in cross-border transactions.

After the signing, the buyer does not yet stop the process. The deed must be registered.

In Greece, signing the deed is essential, but registration with the competent land registry (Ktimatologio) completes the public record of ownership.

---

13. Registration at the Ktimatologio

The final and critical step is registering the deed with the Ktimatologio, the Hellenic Cadastre.

The Ktimatologio records ownership rights, property boundaries, cadastral codes, and registered deeds. It is the official system that confirms the new owner’s right against third parties.

The Hellenic Cadastre provides digital services through which users can submit notarial deeds to cadastral offices, obtain a registration certificate, obtain a copy of a cadastral sheet, and access cadastral diagrams.

The buyer should keep:

• copy of the signed notarial deed,
• proof of submission,
• registration certificate,
• cadastral sheet,
• cadastral diagram,
• tax payment proof,
• notary invoices and related receipts.

If there is an error in the registration, the buyer should correct it as soon as possible. An incorrect KAEK, percentage, or property description can create problems at a future resale.

---

14. E9 Update After the Purchase

After the purchase, the new owner must check the E9 property declaration.

As mentioned above, E9 is the Greek property declaration form used by the tax authority. It records the owner’s real estate assets and affects the annual property tax.

The buyer’s accountant should check:

• square meters,
• floor,
• property use,
• ownership percentage,
• type of right,
• electricity supply number, where relevant,
• correct location,
• correct cadastral details.

If the E9 has an error, the owner should correct it early. Otherwise, the owner may pay the wrong ENFIA or face delays in a future sale.

15. Who Pays What in a Greek Property Purchase?

In a typical Greek property purchase, the buyer usually pays:

• Real Estate Transfer Tax,
• notary fees,
• Ktimatologio registration fees,
• lawyer fee, if represented by a lawyer,
• bank costs, if there is a mortgage,
• buyer-side real estate agency fee, if agreed.

The seller usually pays:

• seller-side certificates,
• debts that block the sale,
• cost for legalizing unauthorized constructions, if needed,
• engineer cost for the Electronic Building Identity, depending on the agreement,
• seller-side real estate agency fee, if agreed.

However, parties may agree differently on some costs. For this reason, all costs should be clarified before the signing date.

---

16. Practical Checklist for Buyers

Before paying a deposit, the buyer should have:

• first legal check,
• first technical check,
• clear ownership picture,
• First review of possible burdens,
• clear price agreement,
• clear cost estimate,
• First check for first-home tax exemption, if relevant.

Before signing the deed, the buyer should have:

• completed title check,
• completed technical check,
• Electronic Building Identity,
• real estate transfer tax declaration,
• tax payment or approved exemption,
• final draft deed,
• safe payment method.

After signing, the buyer should have:

• registration at the Ktimatologio,
• registration certificate,
• updated E9,
• complete property file.

This process helps the buyer reduce risk and avoid unpleasant surprises after the purchase.

17. Common Problems in Greek Property Purchases

Many issues appear late in the process.

For this reason, early due diligence is very important.

Common problems include:

• wrong square meters,
• differences between the title deed, E9, andthe actual property condition,
• unauthorized constructions,
• old mortgages or legal burdens,
• wrong KAEK number,
• delayed TAP certificate,
• seller tax debts,
• inheritance issues,
• unclear parking or storage rights,
• missing floor plans,
• old deeds with unclear descriptions.

Therefore, the buyer should not look only at the price. The buyer should also examine the quality and clarity of the property file.

Conclusion

Buying property in Greece in 2026 can be faster than in the past because several steps are now digital.

However, digital speed does not replace proper legal, technical, and tax due diligence.

A safe purchase follows a clear order:

1. The buyer selects the property.
2. The lawyer checks the title.
3. The engineer checks the technical condition.
4. The seller collects the documents.
5. The notary prepares the tax declaration.
6. The buyer pays the transfer tax or confirms an exemption.
7. The parties sign the notarial deed.
8. The deed is registered at the Ktimatologio.
9. The buyer checks the E9 declaration.

A good property purchase does not start with the signature.

It starts with the right checks.
