If you have a pending inheritance to formalize and there are real estate assets among the property, this change affects you directly. The General Directorate of Legal Security and Public Faith (DGSJFP) has confirmed, through a resolution of May 14, 2026, that the obligation to declare the status of soil regarding contamination applies to all inheritance deeds executed since the entry into force of Law 7/2022, regardless of when the deceased died.
The specific case that gave rise to this resolution is illustrative: the property registrar of Villarcayo suspended the registration of an inheritance acceptance deed because there was no declaration regarding contaminated soil for a single-family home. The notary appealed arguing that the acceptance of inheritance has retroactive effects to the moment of death (which occurred in 2008) and that heirs are acquirers, not transferors. The DGSJFP dismissed the appeal and confirmed the registrar's qualification.
What does this regulation establish?
Law 7/2022 on waste and contaminated soil introduced the obligation that in every transfer of real estate there must be a declaration by the transferor about whether the soil has been subject to potentially contaminating activities. The question debated was whether this obligation applied when the transfer occurs by inheritance and the death is prior to the law.
The DGSJFP establishes the following criteria with clarity:
- The determining date is that of the notarial deed, not that of the death of the deceased. If the deed is executed after the entry into force of Law 7/2022, the obligation is fully enforceable.
- Heirs, as successors of the deceased, assume the obligation to declare whether they have knowledge of potentially contaminating activities in the inherited real estate.
- The argument of retroactivity of inheritance acceptance to the moment of death does not exempt from compliance with the obligation, since the regulation addresses the moment of formalization of the deed.
- This doctrine consolidates previous criteria from 2022, 2023 and 2024, so it is not a new interpretation but a reiterated confirmation.
| Criterion | Position of the appealing notary | Position of the DGSJFP (confirmed) |
|---|---|---|
| Relevant date | Date of death (2008) | Date of notarial deed (after Law 7/2022) |
| Role of heirs | Acquirers, not transferors | Successors of the deceased with obligation to declare |
| Effect of inheritance retroactivity | Exempts from the obligation | Does not exempt from the obligation |
| Result | Appeal granted (claim) | Property registration qualification confirmed — registration suspended |
Economic and operational impact
The impact is not a direct fine, but it can generate indirect costs and significant delays:
- Blocking of property registration: without registration, the heir cannot sell, mortgage or transfer the real estate with full legal guarantees.
- Additional notarial costs: if the deed must be supplemented or redone to include the omitted declaration, new notarial fees and possible management expenses are generated.
- Delays in succession settlements: in inheritances with multiple heirs or with real estate that is to be sold, the registration block can paralyze real estate operations for weeks or months.
- Impact on sales transactions: if the heir had planned to sell the real estate, the lack of registration can cause the transaction to fall through or force a renegotiation.
This doctrine has been applied since 2022, with criteria reiterated in 2023 and 2024. Inheritances with real estate that have not yet been formalized notarially must incorporate this declaration from the outset to avoid suspensions.
Who does it affect?
- Heirs with real estate in the inheritance, especially when the death is prior to 2022 and the deed has not yet been executed.
- Heirs of real estate with industrial, agricultural or commercial history, where the risk of contaminating activities is greater.
- Notaries who must warn heirs of this obligation and incorporate it into the deed.
- Property registrars, who are obligated to negatively qualify deeds that omit this declaration.
- Tax advisors and succession lawyers who manage inheritances with real estate and must include this requirement in their checklist.
- Management firms and property administrators who process inheritance settlements.
Practical example
A family formalizes in 2025 the inheritance acceptance deed of their father, who died in 2008. Among the inherited assets is a single-family home in a town in Burgos. The deed does not include any declaration about the status of the soil regarding contamination.
The property registrar suspends the registration for this reason, exactly as happened in the Villarcayo case that gave rise to this resolution. The heirs must return to the notary to execute a supplementary deed or a corrective deed in which they declare whether or not they have knowledge of potentially contaminating activities in the real estate. This involves new notarial fees, additional processing time and, if they had planned to sell the real estate, a delay that can affect the transaction.
The solution is simple if anticipated: the notary must include the declaration in the original deed. The problem arises when it is omitted due to lack of knowledge or by incorrectly assuming that the death prior to 2022 exempts from the obligation.
What should heirs do now?
- Review whether the inheritance with real estate is pending formalization: if the death is prior to 2022 but the deed has not yet been executed, the obligation to declare the status of the soil is fully applicable.
- Inform the notary before signing: ensure that the inheritance acceptance deed expressly includes the declaration about potentially contaminating activities in each real estate asset.
- Gather information about the history of the real estate: if the inherited property has had industrial, intensive agricultural, commercial uses with chemicals or other risk uses, document it before the deed.
- If the deed has already been executed and suspended: contact the notary to remedy the omission through the corresponding supplementary document, without needing to redo the entire deed.
- Consult with a legal advisor specialized in succession and real estate law if there are doubts about the history of the soil or how to draft the declaration correctly.
Frequently asked questions
Must I declare the status of the soil if the death occurred before 2022?
Yes. According to the DGSJFP resolution of May 14, 2026, what is determining is the date of the notarial deed, not the date of death. If the inheritance acceptance deed is executed after the entry into force of Law 7/2022, the declaration about contaminated soil is mandatory, even if the deceased died in 2008 or earlier.
What happens if I do not include the declaration of contaminated soil in the inheritance deed?
The property registrar may suspend the registration of the real estate, as happened in the case of the Villarcayo Registry that gave rise to this resolution. Without registration, the heir cannot sell or mortgage the property with full legal guarantees. It will be necessary to remedy the deed before a notary, with the additional costs that entails.
What exactly must heirs declare about the soil?
Heirs, as successors of the deceased, must declare whether they have knowledge that the inherited real estate has been subject to potentially contaminating activities. A technical analysis of the soil is not required, but a declaration of knowledge. If there is no information about contaminating uses, it is declared in that sense.
Does this obligation affect only industrial real estate or also homes?
It affects all real estate included in the inheritance deed, including single-family homes. The specific case resolved by the DGSJFP in May 2026 referred precisely to a single-family home whose registration was suspended due to lack of the declaration.
Since when has this criterion been applied?
The DGSJFP has consolidated this criterion through resolutions from 2022, 2023 and 2024, and confirms it again in May 2026. It is not a new interpretation: it has been applied since the entry into force of Law 7/2022. Inheritances formalized since then without this declaration may have been suspended or are at risk of being so.
