In the field of international succession, one of the assumptions that most often gives rise to practical difficulties is the belief that a will made in the deceased’s home country is, by itself, enough to ensure the smooth transfer of assets located in Spain. From a strictly legal standpoint, that may be true in certain cases. However, from a notarial, registry, documentary and tax perspective, relying exclusively on a foreign will usually adds a significantly higher level of complexity to the administration of the estate.

Where a succession includes cross-border elements, the heirs must not only prove their status as beneficiaries of the estate, but also adapt the documentation to the requirements of Spanish law. This may involve sworn translations, apostille or legalisation of documents, evidence of the content and current validity of the applicable foreign law and, more generally, a heavier evidential and administrative burden than in a purely domestic succession.

For that reason, at Certus Legal Firm we frequently make a practical preventive recommendation: if a foreign national owns assets in Spain, it is well worth seriously considering making a Spanish will before a notary.

This does not necessarily mean replacing the deceased’s wider estate-planning arrangements. Rather, it means adding a complementary instrument that makes it possible to organise the succession of assets located in Spain more efficiently and to reduce interpretative, documentary and operational friction when the estate falls to be administered.

Why it is legally advisable to make a Spanish will

A Spanish will, particularly when it is drafted in coordination with the testator’s wider international succession strategy, serves a clear purpose: it simplifies the technical handling of the estate and strengthens legal certainty. It not only makes it easier to identify the relevant testamentary instrument, but also helps ensure that the deceased’s wishes are better integrated into the working framework of Spanish notaries, tax authorities and registries.

Its main advantages are as follows.

  1. It simplifies proof of the succession instrument in Spain

Where the deceased has made a will in Spain, the existence of that instrument can be verified through the General Registry of Wills. From there, the interested parties may request an authorised copy from the notary who holds the original protocol. This sequence considerably reduces documentary uncertainty and allows the succession file to be activated more quickly.

By contrast, where the only succession instrument is foreign, additional steps are usually required to give it practical effect in Spain. Its mere physical existence is not enough. It is essential to determine whether it is formally valid, compatible with the law applicable to the succession and capable of supporting the division, allocation and registration of assets.

  1. It helps structure the succession within the Spanish legal framework

International successions raise a number of highly technical issues: the law applicable to the estate, any choice of law (professio iuris), the interpretation of testamentary provisions, the legal position of forced heirs, and the coordination of different civil and tax systems.

A properly drafted Spanish will does not eliminate these issues altogether, but it can play a decisive role in structuring the file, avoiding contradictions between documents and providing Spanish legal practitioners with a clearer interpretative framework. This is particularly useful where the estate includes real estate, bank accounts, shares or other assets located in Spain.

  1. It reduces indirect costs and processing times

From an economic perspective, the value of a Spanish will should not be measured solely by the cost of making it, but also by its ability to prevent future expenses linked to documentary issues, delays in distributing the estate or duplicated administrative work.

In practice, the clearer and more accessible the succession instrument is, the smoother the preparation of the inheritance deed, the assessment of the taxable base for the relevant taxes and the subsequent registry formalities will be. In succession matters, prevention is usually far more efficient than correcting a poorly structured file after the event.

  1. It makes the process more predictable for the heirs

The role of a will should not be analysed only in doctrinal terms. It also functions as a mechanism for reducing conflict and bringing practical order to the succession process. In complex family situations or emotionally sensitive contexts, the existence of a clear and formally accessible statement of wishes reduces the risk of conflicting interpretations, documentary deadlock and unnecessary delay.

From this perspective, a Spanish will provides not only legal certainty, but also greater manageability throughout the inheritance process.

From a practical standpoint, all of these advantages have a direct impact on the handling of the succession file, which is best understood through its main stages.

How an inheritance is administered in Spain: key stages of the process

Although every succession has its own particular features, and estates with international elements require more sophisticated case-by-case analysis, it is still possible to identify a basic procedural sequence in most inheritance matters involving assets in Spain.

  1. Obtaining the death certificate

The starting point is the death certificate issued by the competent Civil Registry. This document is the essential initial record for any subsequent step, whether notarial, registry-related, administrative or tax-related.

Without formal proof of death, the succession process cannot validly begin.

  1. Applying for the certificate of last wills

Once 15 working days have passed since the death, the Certificate of Acts of Last Will may be requested. Its purpose is to establish whether the deceased made a will in Spain and, if so, to identify the notary before whom the latest valid will was executed.

At the same time, it is common to request the certificate of life insurance and death cover policies, which makes it possible to verify the existence of life insurance or other policies with financial consequences for the estate.

Both certificates are essential in defining the scope of the inheritance file correctly.

  1. Compiling the succession document pack

Before the inheritance can be formalised before a notary, a set of documents must be assembled. Its scope will depend on the composition of the estate, the nationality and residence of the deceased and the status of the heirs.

As a general rule, the following will need to be gathered:

  • an authorised copy of the will, where one exists;
  • identification documents for heirs, legatees or representatives;
  • an NIE or NIF, where required for legal and tax identification in Spain;
  • title deeds for any real estate forming part of the estate;
  • bank certificates showing balances as at the date of death;
  • tax or cadastral documents relating to real estate, including the IBI receipt where relevant;
  • documents relating to vehicles, vessels or other registrable assets; and
  • where applicable, duly formalised powers of attorney.

Where there is no will, this preliminary stage will normally require an intestate declaration of heirs, which is essential in identifying those entitled to inherit under the applicable rules.

  1. Execution of the deed of acceptance and distribution of inheritance

Once the documentary basis has been completed, the heirs, either in person or through a representative with sufficient authority, appear before a notary to execute the deed of acceptance and distribution of inheritance.

This public instrument performs several functions at once: it identifies the successors, incorporates the inventory of estate assets and liabilities, sets valuation criteria, records the division of the estate and specifically allocates the assets to each party.

Its importance is central, as it forms the documentary basis both for tax settlement and for the subsequent registration of the allocated assets.

  1. Settlement of tax obligations

The tax side of an inheritance requires particularly careful review, since the transfer on death of assets located in Spain may trigger several tax liabilities. Their configuration depends on the type of asset, the family relationship involved and the relevant territorial rules.

The most significant taxes include the following.

Inheritance and Gift Tax

Inheritance and Gift Tax must generally be filed within six months from the date of death, without prejudice to the possibility of requesting an extension where legally permitted.

Its calculation does not follow a uniform logic throughout Spain. The actual tax burden may vary significantly depending on the relevant autonomous community, the degree of kinship, the pre-existing wealth of the beneficiary, the net value of the acquisition and other connecting factors.

For that reason, in succession matters, any generic tax approach should be replaced by a territorial and case-specific analysis.

Municipal capital gains tax

Where the inherited assets include urban real estate, the Tax on the Increase in Value of Urban Land, commonly known as municipal capital gains tax, may become payable.

This is a local tax, and its application, calculation and actual enforceability must be assessed in light of the legislation in force and the relevant municipal tax ordinance. There is therefore no automatic or uniform answer for all cases.

  1. Registration at the Land Registry

If the estate includes real estate, full completion of the process requires not only the notarial deed and tax compliance, but also filing with the Land Registry in order to update registered ownership.

Although the status of heir does not arise from the registry entry itself, registration plays an essential role in enforceability, legal certainty and practical operability. Without it, significant practical limitations may arise when attempting to sell, mortgage, merge, subdivide or otherwise dispose of the inherited property.

Timeframes for inheritance matters in Spain: differences between a Spanish will, intestate succession and foreign documentation

There is no single standard timeframe applicable to every succession. The duration of the process will depend, among other factors, on the number of heirs, the degree of agreement between them, the composition of the estate, whether a will exists, the presence of assets in several jurisdictions and the need to provide foreign documents.

Even so, it is useful to distinguish between three basic scenarios.

Inheritance with a Spanish will

Where a Spanish will exists, the estate structure is properly identified and there is no dispute between the persons entitled to inherit, the file can usually be progressed within a reasonable timeframe of a few months.

Inheritance without a will

Where no will exists, the process becomes slower because it first requires the intestate declaration of heirs and, from there, the reconstruction of the succession title before moving on to the division and allocation stage.

Inheritance involving foreign documentation

Where the succession relies wholly or partly on foreign documentation, the need to prove the applicable law, complete legalisation or translation formalities and coordinate actions across different jurisdictions usually extends the process substantially.

Where there is only a foreign will: greater complexity, not an absolute barrier

The fact that the only will is a foreign one does not in itself make the inheritance procedure unworkable in Spain. However, it does mean that the matter must be handled on a more demanding technical level.

In such cases, it will be necessary to verify, among other matters, the formal validity of the document, its effectiveness under the law applicable to the succession, how its content must be evidenced before the Spanish authorities and whether it is capable of supporting the division and allocation of assets located in Spain.

Accordingly, this is usually not an absolute obstacle, but rather a scenario involving greater documentary and evidential complexity.

The need for individual analysis in international successions

In succession law, and especially in international contexts, standardised solutions are rarely satisfactory. The legal answer depends on a combination of connecting factors and patrimonial elements that require individual analysis.

The aspects to be assessed include:

  • the nationality of the deceased;
  • their habitual residence at the time of death;
  • the existence of one or more wills and their internal coordination;
  • the location and nature of the assets;
  • the autonomous community with civil or tax relevance;
  • any application of special regional civil law; and
  • the specific legal position of heirs, legatees or forced heirs.

Only after that analysis can a succession strategy be designed that is both technically sound and tax-efficient.

The issues we solve in international successions and how we approach them at Certus Legal Firm

International successions often raise a common problem: the gap between what the client believes will be enough to transfer their assets and what, in practice, is actually required by the notary, the tax authorities and the registry in Spain.

At Certus Legal Firm, we help bridge that gap by assisting international clients and their families with the planning and administration of inheritances involving assets in Spain from a notarial, asset-management, tax and registry perspective.

Our work may include, among other services:

  • preparing Spanish wills coordinated with international succession structures;
  • carrying out legal review of inheritance documentation;
  • liaising and coordinating with notaries;
  • managing the documents required for non-resident heirs, including the NIE where appropriate;
  • analysing and settling the tax obligations arising from the inheritance; and
  • completing the registry formalities for the allocated assets.

The aim is not simply to complete formalities, but to build a succession pathway that is technically well structured, legally secure and operationally efficient.

Why a Spanish will is a key preventive tool in international successions

For a foreign national with assets in Spain, making a Spanish will can be a highly valuable preventive tool. Its usefulness does not lie solely in expressing the deceased’s wishes. It also helps reduce documentary burdens, improve file traceability and optimise the practical execution of the inheritance.

In a context where civil, tax, notarial and registry issues all converge, planning succession matters in advance is often the best way to reduce future contingencies.

If you hold assets in Spain and would like to assess whether making a Spanish will would be advisable, or how the future administration of your estate should be structured, Certus Legal Firm can help you evaluate the matter through a comprehensive legal approach.
