Inheritance lawyer in Bilbao: the Basque foral regime and its tax advantages for heirs
Estates in Bilbao and across the Basque Country are governed by rules specific to the region, distinct from both the national Civil Code and the tax system of general-regime autonomous communities. The Basque Country has its own foral succession law (Fuero Civil Vasco) and its own fiscal framework: the Juntas Generales de Bizkaia have exclusive regulatory competence over the Inheritance and Gift Tax in Bizkaia. The tax rates, reductions and reliefs applicable in Bizkaia differ from those of other communities, and the foral civil law establishes its own institutions including the troncalismo, the comunicacion foral de bienes and the saca foral. Administering an estate in Bilbao without knowing this specific framework can result in costly tax errors and complex civil disputes.

The problem
Estates in Bilbao and across the Basque Country are governed by rules specific to the region, distinct from both the national Civil Code and the tax system of general-regime autonomous communities. The Basque Country has its own foral succession law (Fuero Civil Vasco) and its own fiscal framework: the Juntas Generales de Bizkaia have exclusive regulatory competence over the Inheritance and Gift Tax in Bizkaia. The tax rates, reductions and reliefs applicable in Bizkaia differ from those of other communities, and the foral civil law establishes its own institutions including the troncalismo, the comunicacion foral de bienes and the saca foral. Administering an estate in Bilbao without knowing this specific framework can result in costly tax errors and complex civil disputes.
Our solution
At BMC we have specialist inheritance lawyers in Bilbao with command of Bizkaia foral law and the tax rules of the Juntas Generales de Bizkaia. We manage the complete administration: succession documentation, asset inventory, partition deed respecting foral law, ISD self-assessment before the Diputacion Foral de Bizkaia, municipal capital gains tax (plusvalia municipal) before Bilbao City Council and Land Registry registrations. Where there is a dispute, we act before the Bilbao Courts of First Instance.
How we do it
Initial documentation and foral analysis
We obtain the death certificate, the certificate of last wills and the copy of the will from the Colegio Notarial del Pais Vasco. We analyse whether the deceased held Bizkaia personal civil law status (vecindad civil vizcaina) for the purpose of applying foral law, and whether the assets include real estate subject to foral troncalismo. If there is no will, we process the intestate declaration of heirs.
Inventory and valuation under foral criteria
We compile the asset inventory taking into account the peculiarities of Bizkaia foral law: the foral community of property in marriage (comunicacion foral de bienes), troncalismo (the rights of troncal relatives over foral real estate) and asset valuation under the criteria of the Diputacion Foral de Bizkaia.
Partition deed and foral rights
We draft the partition deed taking into account the Bizkaia foral forced shares (four fifths of the estate in favour of the children, with freedom of distribution among them), the rights of the surviving spouse and the troncalismo over foral real estate. Where there is a dispute, we intervene in mediation or judicial proceedings.
Settlement before the Diputacion Foral and Land Registry registrations
We file the ISD self-assessment before the Diputacion Foral de Bizkaia, applying the foral reliefs (up to 95% for the spouse and descendants). We manage the municipal capital gains tax (plusvalia municipal) before Bilbao City Council and process registrations in the Bilbao Land Registries.
My father had an apartment in the Bilbao Casco Viejo and an account with Banco Bilbao. We knew nothing about the Basque Fuero or how estates are handled here. BMC explained the troncalismo system, applied the foral relief correctly and resolved everything within the deadline. Outstanding handling at a very difficult time.
Estates in Bilbao: Basque foral law on succession
Bilbao and the Territorio Historico de Bizkaia as a whole are governed by their own legal framework, the Fuero Civil de Bizkaia, which establishes specific succession rules that differ from the national Civil Code applicable in the rest of Spain. In tax matters, the Juntas Generales de Bizkaia have exclusive regulatory competence to govern the Inheritance and Gift Tax in their territory, meaning that the rates, reductions and reliefs applicable in Bilbao are those of the Basque foral regime.
This dual specificity, civil and fiscal, means that administering an estate in Bilbao requires specialist knowledge. The BMC inheritance lawyers in Bilbao combine command of Bizkaia foral law with experience before the Diputacion Foral de Bizkaia and the city’s Land Registries.
Inheritance and Gift Tax in Bizkaia: one of the most favourable foral regimes for direct heirs
The Bizkaia Inheritance and Gift Tax rules, approved by the Juntas Generales, establish a very favourable taxation system for the deceased’s direct heirs. The relief applicable to spouses, descendants and ascendants is 95% of the gross tax liability, meaning that an inheritance between parents and children in Bilbao is taxed at only 5% of what would apply without the relief.
This 95% relief in Bizkaia applies automatically to Group I and II heirs. For siblings and collaterals (Group III), the relief is 50%. For Group IV heirs (strangers to the family), there is no relief and the full tariff applies.
Additionally, the Bizkaia foral rules establish specific reductions for the acquisition of a family business, for a disabled heir and for the transfer of the main residence.
The Fuero Civil de Bizkaia: specific institutions affecting estates
The Fuero Civil de Bizkaia (contained in Ley 5/2015 on Basque Civil Law) establishes a set of specific succession institutions that do not exist in the national Civil Code:
Foral troncalismo
The troncalismo is the most distinctive institution of Bizkaia foral law. It applies to real estate located in the infanzonado territory of Bizkaia (most of the historic territory, excluding the municipalities of the Tierra Llana which follow general Spanish law). Foral troncal assets are those which the deceased acquired by inheritance or gift from the troncal family.
Troncal relatives have two fundamental rights over these assets:
- Saca foral: if the deceased disposes mortis causa of the troncal assets in favour of someone who is not a troncal relative, the troncal relatives may exercise the right of redemption (saca) within four years of the transfer, paying the acquisition price.
- Preferential right in intestate succession: if the deceased dies without a will, the troncal assets pass preferentially to the troncal relatives, following the line of acquisition of the asset.
Identifying the troncal assets in an estate requires a specific analysis of the acquisition history of each property.
Foral community of property (comunicacion foral de bienes)
In a marriage governed by the Bizkaia fuero, the spouses may have a foral community of property regime, by which all the assets of both spouses, including individually owned assets, form a common pool. This regime has direct consequences on the estate: on the death of one spouse, the surviving spouse is entitled to half of the foral community, thereby reducing the estate assets on which the heirs’ rights are calculated.
The surviving spouse’s usufructo poderoso
The surviving spouse in Bizkaia has, where stipulated in a marriage settlement or will, the right to the “usufructo poderoso”: a usufruct with extensive powers that may include the power to dispose of assets for their own benefit. This right is broader than the mere universal usufruct under the national Civil Code.
The Bizkaia foral forced share (legitima)
The forced share under the Fuero Civil de Bizkaia is four fifths of the estate in favour of the children and descendants, with the testator free to benefit some descendants over others within that limit. This means the testator may favour one child over the others (unlike general Spanish civil law, where the strict forced share must be divided equally among all children), provided that the total left to all descendants is not less than four fifths of the estate.
Inheritance disputes in Bilbao: specific patterns
Casco Viejo and Bilbao Ensanche: Bilbao’s property market has seen significant appreciation. Apartments in the Casco Viejo, Ensanche, Indautxu, Deusto or Algorta (Getxo) generate disputes when heirs cannot reach agreement. The division of the estate may require judicial proceedings before the Bilbao Courts of First Instance.
Troncal assets with non-family heirs: Where the deceased leaves foral troncal assets to heirs who are not troncal relatives (for example, to a spouse who is not part of the troncal family), the troncal relatives may exercise the saca foral. This situation generates disputes that require a specific analysis of the Land Registry history of each asset.
Industrial family businesses: The Bizkaia industrial fabric (manufacturing, shipbuilding, steel, energy) generates estates with company shares of complex valuation. The foral ISD family business reduction requires compliance with specific requirements that must be planned in advance.
Estates with assets in several autonomous communities: It is common for a Bilbao resident to also have assets in other autonomous communities (an apartment on the Cantabrian coast, a property in Madrid). In that case, the ISD on assets outside Bizkaia is settled before the tax authority competent for each territory, while the ISD on assets in Bizkaia falls to the Diputacion Foral.
Estates with non-resident heirs in Bilbao
Heirs not resident in Spain have the same tax obligations as residents with respect to assets in Bizkaia. The deadline is the same (six months) and tax competence lies with the Diputacion Foral de Bizkaia where the deceased was resident in the Territorio Historico.
At BMC we manage the representation of non-resident heirs before the Diputacion Foral de Bizkaia, the obtaining and apostillation of documents, coordination with advisers in the heirs’ country of residence, and correct settlement of the foral ISD. We also advise on the interaction between the estate and the wealth tax in Bizkaia when the inherited assets exceed the taxation thresholds.
Succession planning in Bilbao: make the most of foral law
The Fuero Civil de Bizkaia offers specific succession planning tools that do not exist in general Spanish civil law. These include:
- Wills with improvements: The greater freedom of disposition under the Bizkaia fuero (only one fifth of the estate is protected from unequal distribution among children) allows for more flexible wills than under general Spanish law.
- Foral community of property: The foral community of property regime can be advantageous in certain matrimonial situations for optimising the tax burden and the distribution of assets among the heirs.
- Succession agreements: Basque civil law permits certain succession agreements during the deceased’s lifetime.
At BMC we offer a succession planning service specifically adapted to Bizkaia foral law, covering analysis of troncal assets, simulation of succession scenarios and design of the most efficient will.
