Succession pact in Spain: asset protection
A succession pact in Spain is an irrevocable notarial agreement for the lifetime transfer of property. This instrument eliminates personal income tax for the transferring party.
The institution of lifetime inheritance is a complex mechanism of regional civil law. In 2026, tax planning requires surgical precision when structuring the transfer of large capitals. Wealthy expats, residents, and investors face confiscatory taxation levels when attempting to transfer real estate or business to the next generation. Standard procedures entail colossal financial losses. Competent asset protection requires the application of specialized legal constructs that go beyond the general Civil Code.
Pacto Sucesorio acts as a legal alternative to traditional methods of property alienation. This contract allows fixing the testator's will and executing the actual transfer of property rights before their physical death. The legal nature of this agreement differs radically from standard transactions. The parties conclude a bilateral contract. The testator transfers the asset. The heir accepts it, often waiving further claims to the rest of the inheritance estate.
Law enforcement practice in 2026 confirms the absolute legitimacy of this instrument in specific territories. The Supreme Court of Spain has formed a stable doctrine. The Tax Agency (Agencia Tributaria) must recognize the fiscal advantages of such contracts subject to strict procedural norms. Implementing the pact requires a deep analysis of conflict of laws, the tax residency status of the parties, and the local legislation of autonomous communities.
The problem of classic donation (Donación)
Classic donation triggers two parallel tax obligations. The recipient pays the donation tax, and the donor compensates for the fictitious capital gain.
Donación under general Spanish law (Derecho Común) is considered a gratuitous transfer of assets (inter vivos). Article 618 of the Spanish Civil Code defines this transaction as an act of liberality. A person voluntarily disposes of a thing in favor of another person who accepts it. However, the fiscal consequences of such an act make it economically unviable for high-value assets. Transferring property to children through a standard donation contract triggers a double taxation mechanism.
The state views donation not merely as a change of ownership. The tax system interprets this operation as the realization of an asset. A paradoxical situation arises. The donor receives no funds from the donee. Meanwhile, the law obliges the donor to pay tax as if they sold the property at current market value. This fiscal trap annually leads to the bankruptcy of families who failed to calculate tax consequences before signing the notarial deed.
The donation execution procedure requires mandatory notarial certification if it involves real estate. Article 633 of the Civil Code establishes strict requirements for the transaction form. Failure to comply with the form renders the contract void. The notary must notify the tax authorities about the completed transaction. From this moment, the deadlines for filing tax returns by both parties begin.
Double taxation: ISD for the recipient and IRPF for the donor
The Spanish tax system taxes the gratuitous transfer of assets twice. Impuesto sobre Sucesiones (ISD) arises for the donee and IRPF for the donor.
The asset recipient becomes subject to the inheritance and donation tax (Ley 29/1987). The tax rate is progressive. In 2026, the base scale ranges from 7.65% to 34%. The final amount is adjusted considering multiplication coefficients (coeficientes multiplicadores). These coefficients depend on the degree of kinship and the size of the recipient's pre-existing wealth (patrimonio preexistente). The maximum coefficient can more than double the base rate.
The donor, in turn, falls under the personal income tax law (Ley 35/2006). The asset transfer is classified as an alteration in the composition of wealth (alteración en la composición del patrimonio). The tax base is calculated according to the savings scale (base imponible del ahorro). In 2026, IRPF rates for capital gains are distributed as follows: 19% on the first 6,000 euros, 21% from 6,000 to 50,000 euros, 23% from 50,000 to 200,000 euros, 27% from 200,000 to 300,000 euros, and 28% on amounts exceeding 300,000 euros.
The synchronous application of two taxes creates a cumulative effect. The total fiscal burden on the family can reach 40-50% of the real market value of the transferred object. This makes traditional donation an absolutely inefficient instrument for structuring large capitals. Spanish tax residents must declare such operations regardless of the country where the transferred asset is located.
Fictitious capital gain tax
Fictitious capital gain is calculated as the difference between the asset's acquisition cost and its current market valuation. The donor must pay tax on this non-existent profit.
Ganancia patrimonial arises at the moment of the notarial execution of the donation. The tax agency applies the concept of "reference value" (valor de referencia) to evaluate the transferred property. Since 2022, according to Law 11/2021 on measures to prevent tax fraud, the base for calculation is the cadastral reference value determined by the General Directorate of Cadastre. In 2026, this mechanism operates automatically.
The capital gain calculation formula is as follows. The historical acquisition cost (Valor de Adquisición) is subtracted from the current reference value (Valor de Transmisión). The acquisition cost includes the real purchase price, paid taxes (ITP or IVA), notarial expenses, and capital repair costs. Depreciation is deducted if the property was rented out. The resulting difference forms the taxable base.
An example from practice. An investor purchased a villa in 2010 for 300,000 euros. In 2026, the reference value of the object is 1,000,000 euros. When donating the villa to his son, the investor receives no money. However, the tax agency records a capital gain of 700,000 euros. The investor must pay IRPF on this amount according to a progressive scale up to 28%. The tax amount for the donor will exceed 180,000 euros. This is a classic example of fiscal expropriation when using standard civil law mechanisms.
Pacto Sucesorio in regional law (Derecho Foral)
The institution of the succession pact is regulated exclusively by the norms of Derecho Foral. The national Civil Code of Spain expressly prohibits such contracts regarding future inheritance.
The Spanish legal system is characterized by the pluralism of civil legislation. Article 149.1.8 of the Spanish Constitution guarantees the preservation, modification, and development of special civil rights (derechos civiles forales o especiales) where they historically exist. The general Civil Code (Código Civil) applies to most of the country's territory. Article 1271 of the Civil Code categorically prohibits concluding contracts regarding future inheritance. Any succession pact in Spain concluded by residents of common law territories (for example, Madrid or Andalusia) is declared void (nulo de pleno derecho).
Regional law offers a completely different paradigm. The historical compilations of civil law of Aragon, the Balearic Islands, Catalonia, Galicia, Navarre, and the Basque Country allow contractual inheritance. These territories have preserved ancient institutions aimed at keeping family property intact. In 2026, these archaic norms have become a powerful instrument of modern tax planning.
The application of regional law depends on the concept of civil neighborhood (vecindad civil). This is not the same as administrative registration (empadronamiento). Civil neighborhood determines exactly which civil legislation an individual is subject to. Acquiring vecindad civil requires either ten years of continuous residence in the territory of an autonomous community or two years of residence with the submission of a special application to the civil registry offices (Registro Civil).
Application in the Balearic Islands and Catalonia
The legislation of Catalonia and the Balearic Islands allows the conclusion of lifetime inheritance contracts. This legally bypasses federal restrictions.
In Catalonia, succession pacts are regulated by Law 10/2008 (Book IV of the Civil Code of Catalonia). Article 431-1 and subsequent articles establish strict frameworks. The contract can only be concluded between persons related by blood or marriage (spouses, cohabitants, direct relatives, collateral relatives up to the fourth degree). Catalan law distinguishes two main types of pacts: the heir institution pact (pacto de institución de heredero) and the specific attribution pact (pacto de atribución particular). The latter allows transferring a specific asset (e.g., an apartment) during the testator's lifetime. Donation tax Catalonia does not apply in this case, as the transaction is classified as inheritance.
The Compilation of Civil Law (Decreto Legislativo 79/1990) operates in the Balearic Islands. The legal regime varies depending on the specific island. On Mallorca and Menorca, the "Pacto de Definición" is applied. Under this contract, a descendant (emancipated or of legal age) waives their rights to a future legal share (legítima) in exchange for the immediate receipt of assets from the parents. On Ibiza and Formentera, the "Pacto de Finiquito" is used, having a similar legal nature. Inheritance tax Balearics in such transactions is calculated applying maximum regional benefits.
The procedure requires the mandatory participation of a notary. The Notario must verify the presence of the appropriate civil neighborhood of the testator. The contract is executed as a public deed (escritura pública). The document text details the transfer conditions, possible clauses on the right of usufruct (usufructo) for the transferring party, and the conditions for canceling the pact. Strict compliance with formalities is a critical factor for the subsequent recognition of the transaction by tax authorities.
Complete exemption of the donor from paying IRPF
The transfer of assets through a pact is classified as inheritance, not donation. This completely exempts the transferring party from paying income tax.
The key fiscal advantage of the succession pact lies in the absence of fictitious capital gain tax. Article 33.3.b of the Personal Income Tax Law (LIRPF) explicitly states that a capital gain or loss does not arise when property is transferred due to death (mortis causa). For a long time, the tax agency tried to challenge the application of this norm to lifetime pacts, arguing that the transfer occurs during the testator's life.
The Supreme Court of Spain put an end to the disputes. In a series of precedent-setting decisions (specifically, STS 252/2021), the court ruled that Herencia en vida (lifetime inheritance) through regional law pacts has a "mortis causa" nature for tax purposes. Consequently, the transferring party is completely exempt from paying IRPF. The donor's tax base remains zero, regardless of the difference between the acquisition cost and the current market valuation of the asset.
However, in 2021, Law 11/2021 was adopted, introducing an important anti-fraud amendment to Article 36 of the LIRPF. This amendment remains in effect in 2026. The essence of the restriction: if the heir sells the property received under the pact before the expiration of five years from the moment of signing the pact or before the testator's death (whichever comes first), the heir must use the original acquisition cost of the asset by the testator when calculating their capital gains tax. This norm prevents the use of pacts exclusively for quick "laundering" of the tax base before the immediate sale of real estate to third parties.

Succession pact in Spain: Frequently Asked Questions
This section contains precise legal answers to the most frequent questions from VissumLex clients. The information is current for 2026.
Can a Pacto Sucesorio be concluded in Madrid or Valencia?
No, residents of common law territories (Derecho Común) cannot use this instrument. Civil residence (vecindad civil) in the respective region is required.
Madrid, Valencia, Andalusia, and most other regions of Spain are subject to the general Civil Code. Article 1271 expressly prohibits contracts regarding future inheritance. If a resident of Madrid attempts to conclude such a contract, the notary will refuse to certify the transaction. If the transaction is executed fraudulently, the tax agency will reclassify it as a regular donation (Donación) and assess taxes with penalties. To use the pact, it is necessary to legally change the vecindad civil by moving to Catalonia, the Balearics, Aragon, or Galicia, and living there for the required time (10 years automatically or 2 years with an application).
What happens if the heir sells the real estate immediately after receiving it?
Upon selling the asset before the expiration of five years or before the death of the transferring party, the heir will pay capital gains tax. The base will be the original acquisition cost of the asset by the donor.
This is a direct consequence of the anti-fraud Law 11/2021. The state closed the loophole for speculation. If a son receives a villa under a pact (appraised value 1 million, father's historical cost 300 thousand) and sells it a year later for 1.1 million euros, he will pay IRPF on the difference between 1.1 million and 300 thousand (base 800 thousand euros). If the son waits 5 years (or if the father passes away before this period expires), the base for calculating the tax upon sale will be the difference between 1.1 million and 1 million (base only 100 thousand euros). This is a critically important nuance for liquidity planning.
Can a non-resident of Spain use the Succession pact?
Yes, European Regulation 650/2012 allows non-residents to apply the law of the region where the real estate is located. However, a thorough analysis of conflict rules is required.
EU Regulation 650/2012 (Brussels IV) unifies inheritance rules in Europe. Article 25 of the Regulation directly regulates succession agreements (pactos sucesorios). If a German citizen owns a villa in Mallorca, they can choose Spanish law (specifically the law of the Balearic Islands) to regulate the transfer of this asset. However, it is necessary to consider the tax consequences in the recipient's country of residence. The German tax agency may not recognize the Spanish classification of the transaction as "mortis causa" and tax it with donation tax at German rates. International structuring requires the participation of lawyers from both jurisdictions.
Can a Pacto Sucesorio be canceled if relations with children deteriorate?
As a general rule, the pact is irrevocable. Cancellation is possible only with the mutual consent of the parties or the occurrence of conditions strictly stipulated in the contract.
This is the main difference between a pact and a will. A will is a unilateral act that can be rewritten even every day. A pact is a bilateral contract. The testator cannot simply go to a notary and annul it unilaterally. Cancellation (revocación) is allowed only in exceptional cases provided by regional law (for example, gross ingratitude of the heir, attempt on the testator's life) or upon the heir's failure to fulfill conditions explicitly stated in the pact itself (for example, the obligation to care for the testator in old age).
Does this mechanism apply to the transfer of business shares (S.L.)?
Yes, corporate rights can be the object of a succession pact. This is an effective tool for planning the succession of a family business.
The transfer of shares (participaciones sociales) in a Spanish limited liability company (Sociedad Limitada) through a succession pact allows not only avoiding IRPF for the business founder but also applying a 95% exemption on inheritance tax (ISD) for family enterprises. Article 20.2.c of the ISD Law establishes strict requirements for this exemption: the founder must be over 65 years old, cease performing managerial functions, and stop receiving remuneration for them. The pact allows smoothly transferring control over the company to successors, fixing corporate agreements in a notarial deed.
What is the difference between a Succession pact and a regular will?
A will comes into effect only after the testator's death and can be changed at any time. A pact has immediate effect and is not subject to unilateral cancellation.
A will (Testamento) does not transfer property rights during life. Heirs receive assets and pay taxes only after obtaining a death certificate and signing an act of inheritance acceptance. A succession pact in Spain (in the form of transferring assets de presente) means that the change of owner in the Property Registry (Registro de la Propiedad) occurs immediately, on the day the contract is signed. The heir becomes the full owner (or the owner of bare ownership if a usufruct is established) even during the testator's lifetime.
