In Spain, we defend international heirs and families when a significant inheritance becomes complicated due to a disputed will, assets in Spain, hidden assets, multiple wills, or heirs in different countries. We analyze what rights the client has, what documents can be challenged, what assets should be claimed, and what actions should be taken in Spain in the following situations:
The will favors a specific person, excludes expected heirs, or was signed when the testator was ill, isolated, or dependent on others. We review whether it can be contested in Spain.
The inheritance includes real estate, companies, accounts, investments, or other assets in Spain. It may also include undeclared assets, previous transfers, or suspicious transactions. We analyze which assets should be included in the inheritance.
The deceased, the heirs, the assets, or the documents are spread across several countries. We organize the strategy in Spain and coordinate actions with other professionals when necessary.
If you need to raise an international inheritance dispute in Spain, here you will find the ways to contact RRYP Global.

Our international inheritance lawyers' practice is geared towards foreign heirs who need to maintain a serious legal position in Spain in successions with significant assets, complex assets or patrimonial structures distributed between several countries. We intervene if any of these situations are recognized:

RRYP Global lawyers litigate international successions before the Courts of Spain. In an international inheritance case, the conflict usually begins with two questions: which law governs the inheritance and what is the validity of the will that is intended to be executed in Spain? The answer to this question determines not only the distribution of the estate, but also the legal standing of each heir and the legal actions that can be taken.
Therefore, we must:

When the deceased was a foreigner or there are assets in several countries, a will signed in Spain must be analyzed within the context of the entire estate. We review its actual scope and whether it could unduly prejudice heirs located abroad.
Spanish law does not always apply. Residence, nationality, assets, and the choice of law can all affect who inherits, how much they inherit, and whether the will is valid.
There may be a will in Spain, a will in the country of origin, and conflicting documents. We organize dates, content, and effects to determine which document should prevail or be challenged.
A notarized will does not eliminate all doubts if there was illness, dependency, isolation, or cognitive decline. We analyze medical documentation, the context of the signing, and any third-party involvement.
Sudden changes of heart, unexpected beneficiaries, family isolation, or dependence on a favored person can all be relevant. The key is to turn suspicion into useful evidence.
In high-value inheritances, real estate, companies, accounts, shares, or previous transfers may be missing. We reconstruct the assets to determine what should be claimed.
A Spanish will, power of attorney, deed, company, or property can affect an inheritance opened abroad. We analyze what can be done in Spain to protect the inheritance rights of the heirs.
Being right isn't enough. You have to prove ability, willingness, assets, documents, dates, and relevant actions. That's why we start with a strategic analysis.
Challenging a complex international will requires understanding how different legal systems operate and mastering the rules of private international law. At RRYP Global, we handle these types of proceedings with an international, technical, and asset-focused perspective, tailored to situations involving multiple nationalities, residences, assets, and legal frameworks.
From the first contact, the matter is analyzed and managed by Mar Gámez. From the outset, the client has a clear point of contact, capable of assessing the viability of the appeal, the evidentiary risks, and the best strategy in Spain.

Each international will contest is structured in specific legal phases: analysis of the will, review of the law applicable to the estate, examination of the statutory share, the testator's capacity, potential defects of consent, undue influence, asset documentation, and procedural strategy. The client knows at every stage what will be done, why it is being done, and what the next step is.

We work in Spanish and English and are prepared to review probate documents in other languages with specialized technical and professional support. We coordinate death certificates, foreign wills, declarations of heirs, apostilles, legalizations, sworn translations, and communications with notaries, registries, embassies, consulates, and professionals in other countries when the case requires it.


We have worked from Spain on issues related to countries such as Mauritania, Indonesia, Vanuatu, the USA, Argentina, Cuba, Panama, Sweden, Switzerland, the UK, France, Portugal, Italy, Belgium and Germany, among others.
RRYP Global handles complex international will contestation cases in Spain when the succession requires clearly determining which law is applicable, which court has jurisdiction, the validity of the will executed in Spain or abroad, and how the rights of heirs and statutory beneficiaries should be protected when there are assets, relatives, or succession documents in several countries.

Countries involved, habitual residence of the deceased, nationalities, location of assets, wills executed in Spain or abroad, affected heirs, and potential inheritance rights. We identify risks, deadlines, key documents, and the feasibility of contesting an international will.
We define the legal and procedural framework in Spain: applicable law for succession, judicial jurisdiction, validity of foreign wills, possible grounds for challenge, protection of the statutory share and strategy against other heirs, executors or administrators of the estate.
We work with documentation and professionals from other jurisdictions when the case requires it, to avoid contradictions, duplications or poorly planned actions.
We take care of preparing the strategy, gathering the necessary documentation, analyzing the testator's capacity, undue influence or violation of the statutory right, coordinating experts and interpreters, and representing the client in legal proceedings for challenging international wills in Spain.
Our team combines expertise in international law with the ability to represent clients in Spanish courts. We understand that every family law case with cross-border implications requires a well-designed legal strategy, respect for the legal framework of each country involved, and sensitive conflict management.
