Notarial valuation grid 2026: how to find the minimum value of a flat, house or plot of land
The notarial valuation grid is one of the benchmarks used in property transactions: it publishes reference values for categories and areas, which the rules may use for certain fees or tax liabilities. It does not replace legal analysis and is not tax advice, but it is worth checking before signing.
- The 2026 notarial valuation grid indicates minimum reference values by area, property type and relevant characteristics.
- For the authentication of property deeds, if the declared value is below the minimum value in the study, notarial rules require the fee to be calculated using the value in the study.
- For notarial fees when buying a flat, the final cost depends on the price, the property's minimum value, legal status, loan and required documents.
- Verifi Standard brings together the notarial valuation grid value, land register extract and risk indicators that may change the purchase decision in one report.
What the notarial valuation grid tells you
The grid does not set the market price, but helps you estimate the minimum basis for fees and ask questions when differences are large.
Verifi helps you prepare the right questions and identify important warning signs. For complex legal situations, clarify the decision to sign with your notary or lawyer.
The notarial valuation grid is a tax benchmark, not a market valuation
Use the grid for budgeting and questions, then compare it with the negotiated price and the property documents.
Large differences between the grid and price warrant an explanation before signing.
What the notarial valuation grid is
The notarial valuation grid is a set of minimum property values, usually organised by locality, area, property type and characteristics such as floor area, use or age. In practice, the 2026 notarial valuation grid serves as a transaction benchmark, not a personalised valuation of a particular property.
For a buyer, its usefulness is straightforward: it shows whether the price being discussed is close to a threshold used in the notarial procedure and helps you estimate completion costs more realistically. The grid value does not mean that the flat, house or land is worth exactly that amount; it simply indicates a minimum value used as an administrative benchmark.
What the property's minimum value means
The term property's minimum value refers to the estimated threshold in the grid for a property with certain characteristics. For a flat, the value may depend on the locality, neighbourhood, area, floor, year of construction and usable area. For a house, the building and associated land may be assessed separately. For land, location, whether it lies within or outside the built-up area, and the land-use category matter.
Normally, the sale price is freely negotiated between the parties. However, if the price declared in the contract is below the minimum value in the grid, the notary may be required, or follow a practice, to use the higher value for certain calculations. Final confirmation must come from the notarial office handling the deed.
How it applies to a flat, house or land
Flat
For a flat, the grid usually starts with the location and floor area. Adjustments or classifications may apply based on comfort level, year of construction, floor or other local criteria. For notarial fees when buying a flat, the difference between the negotiated price and the grid threshold may change the estimated transaction cost.
House
For a house, the calculation may combine the building's value with the land's value. An old house on valuable land may be assessed differently from a new building on the outskirts. It is therefore important to check both the built area and year of construction, as well as the land register details.
Land
For land, the minimum value is strongly influenced by location and classification: within or outside the built-up area, yards and buildings, agricultural, road frontage, access and sometimes development potential. The grid is only a benchmark; the actual risks may arise from easements, lack of access or planning restrictions.
How it affects the calculation of notarial fees
When looking for a notarial fee calculation, you will usually see estimates for the notary's fee, land register charges and possible costs associated with the loan or authentication. The calculation may be based on the contract price or the property's minimum value in the grid, depending on the circumstances and the rules applied by the notary.
As a buyer, the most prudent approach is to treat online estimates as indicative. Notarial fees for buying a flat may differ from those for a house or land, and the notary will confirm the calculation based on the actual documents, VAT treatment, loan, mortgage, co-owners and other details.
For transfer tax, the Tax Code and its implementing rules distinguish between the declared value, the minimum value in the market study and special cases such as limited rights in rem or bare ownership. It is not correct to apply the same formula automatically to every transaction; the notary confirms the treatment of the specific deed. See the guide to tax on a sale (forms 208 and 209).
How to find the minimum value in the 2026 notarial valuation grid
To find the minimum value, you need to identify the property correctly: address, locality, area, property type and, where available, land register details. For land and houses, cadastral details can be decisive, because the same address may include several buildings, ownership shares or land-use categories.
- Check the area and property description in the available documents.
- Confirm the classification: flat, house with land or separate land.
- Compare the agreed price with the minimum value used as a benchmark.
- Ask the notary to confirm the calculation basis before signing.
With Verifi Standard, the notarial valuation grid value is delivered with the land register extract and an analysis of relevant risks, so that you do not assess the price separately from the legal position. See also the notarial valuation grid for your county.
When the grid value may differ from the price
A difference between the price and the grid often arises when a property has issues that are difficult to capture in a standard value: necessary renovations, seismic risk, litigation, encumbrances, unclear access, difficult surroundings or planning restrictions. The reverse can also happen: an excellently renovated flat or land with potential may sell for much more than the grid value.
A minimum value above the negotiated price does not automatically mean there is something wrong with the transaction. It is a prompt to investigate: why is it selling below the threshold? Is there genuine urgency, a legal problem, a technical issue or simply good negotiation? Look for the answer in documents, not assumptions.
What to check before signing
The grid helps with costs, but the purchase decision rests on risks. Before paying the deposit or signing the contract, at least check ownership, encumbrances, mortgages, prohibitions, recorded litigation, areas and whether the documents match reality.
- Land register extract: owner, encumbrances, mortgages, prohibitions and relevant notices.
- Notarial value: a benchmark for estimating costs and discussing them with the notary.
- Property risks: seismic risk, flood-prone areas, access, easements or restrictions that may affect use.
- Consistency of documents: address, cadastral number, areas, shares and registered rights.
Verifi Standard is designed for precisely this stage: notarial value, land register and risks in a single report, with a clear status for each source and explanations for the buyer.
Frequently asked questions
Does the notarial valuation grid set the sale price?
No. The price is negotiated between seller and buyer. The grid is a minimum-value benchmark used for notarial and tax purposes, not a binding market valuation.
Can I calculate the exact fees using the grid alone?
Not always. The grid helps with estimates, but the final calculation depends on the specific deed, price, loan, mortgage, number of parties and transaction details. The notary confirms the final amount.
Why check the grid if I am going to a notary anyway?
Because you can estimate your budget earlier and spot differences between the negotiated price and the property's minimum value. This helps you ask the right questions before committing money to a deposit.
Does Verifi replace the notary?
No. Verifi does not authenticate deeds or provide notarial advice. Verifi helps you check the property before the transaction: notarial valuation grid, land register and relevant risks, in an easy-to-read format.
