International will in Italy
The Italian legal system provides for various forms of will, instruments essential to ensure the transmission of patrimony in conformity with the wishes of the deceased. Among these, a relevant form in international scope is the international will for foreigners in Italy, introduced with legge n. 387 of 29 November 1990.
With such regulation, Italy has adhered to the Convenzione di Washington of 1973, an international agreement that aims to create a uniform modality of will with validity recognised also beyond the borders of the adhering Countries.
This instrument facilitates the management of successions for foreign citizens residing in Italy and for any person residing abroad outside the national territory.
The Convenzione di Washington responds to a need increasingly widespread in a globalised world: reducing the interpretative problems linked to the law applicable to the will.
In international cases, in fact, the differences between legal systems can create uncertainties and difficulties, both for testators and for heirs, and lead to legal disputes or bureaucratic obstacles that could complicate the execution of the wishes of the deceased. The Convention therefore aims to ensure uniformity and legal certainty in testamentary provisions, facilitating persons who possess patrimonies in multiple Countries or who, for personal or professional reasons, live a transnational reality.
Recourse to the international will
From the point of view of legal effects, the international will is comparable to the other testamentary forms provided for by the Italian Codice civile, such as the public, holographic and secret will.
Its validity is recognised at international level, thanks to the Washington Convention of 26 October 1973, ratified by Italy with legge n. 387/1990.
This convention introduced a uniform form of will that aims to facilitate succession in international contexts, where assets and beneficiaries can be located in multiple States, reducing legal barriers and difficulties of recognition between different legal systems.
The international will is distinguished from the other testamentary forms provided for in Italy for its particular formal modalities of drafting, which require the presence of a notary and of two witnesses. This formal requirement has the purpose of conferring certainty and solemnity on the document, reducing the possibility of fraud or contestations.
During the drafting, the testator declares before the notary and the witnesses that the document is their will, without however being obliged to reveal its content.
This form of will is similar to the secret will, since, as in the latter, the content of the international will may remain unknown both to the witnesses and to the notary. The testator can therefore keep their provisions confidential, avoiding their being known by third parties during their life.
After the testator’s declaration, the notary draws up a certificate that attests to compliance with the formalities provided for by law, attaching it to the will itself.
Such certificate represents an essential element to ensure the validity of the international will, since it provides proof of the modalities with which it was drafted, strengthening its recognisability and applicability abroad.
Italian succession law regulates the content of the international will, ensuring that the wishes of the testator are respected and managed according to the ordinary provisions on succession matters. In other words, even if the will is drafted following an international form, the provisions of the testator must nevertheless respect the principles and limits of Italian inheritance law, such as respect for the shares of forced heirship reserved to necessary heirs. Furthermore, should the international will contain provisions that are not valid or applicable according to Italian law (for example, in the case of clauses that violate the rights of legitimate heirs), these provisions could be declared void, although the rest of the will remains valid.
It is fundamental that the international will respects all the formalities required, since the lack of one of the requirements provided for could entail its invalidity. For example, the absence of witnesses, the lack of presence of the notary or the lack of the certificate of conformity could lead to a declaration of nullity of the will, thus rendering ineffective the provisions of the testator. For this reason, the drafting of an international will requires particular attention and professional competence, ensuring that it produces legal effects not only in Italy but also at international level.
The international will, furthermore, represents a valuable instrument for those who possess assets in multiple Countries or for those who have family members residing abroad, since its validity and recognisability are ensured by the 1973 Washington Convention in the adhering Countries. This means that an international will drafted in Italy and compliant with the convention can be recognised and applied in another signatory State without the need for further formalities, facilitating the succession process and protecting the rights of heirs according to the wishes of the testator.
Who can make an international will
The 1973 Washington Convention is based on principles of inclusiveness, designed to allow the greatest number of persons to avail themselves of the international will. This instrument can be used by various subjects, without any distinction of nationality, who meet the requirements of capacity to draft a will.
The following can avail themselves of the international will:
- Italian citizens, both those who live in Italy and those who reside stably abroad. For Italian citizens residing in foreign Countries, it is provided that the will can be received by an Italian diplomatic or consular agent authorised in the Country of residence, thus avoiding the need to turn to a foreign notary and ensuring greater legal continuity with the Italian system.
- Foreigners residing in Italy, coming from Countries that have adhered to the Convenzione di Washington or that recognise the validity of a will drafted abroad. This also allows foreign citizens to benefit from Italian testamentary provisions, on condition that their legal system of origin does not contradict the principles of the Convention.
Italian law does not specify particular requirements of capacity to draft an international will, limiting itself to requiring that the testator understands the provisions they are formalising.
Consequently, even persons who present disabilities, such as deafness, blindness or incapacity to read and write, can draft an international will. This characteristic represents a relevant difference compared to the secret will, for which it is necessary that the testator possesses the capacity to read and write.
A lawyer for succession matters can help to manage all legal aspects linked to the inheritance, ensuring that the drafting of the will and the provision for every wish takes place in compliance with the regulation in force.
What are the differences between international will and Italian will?
The international will is distinguished from the Italian will mainly for the formal modalities of drafting and conservation. While a holographic or secret will in Italy can be written and kept without the need for witnesses, the international will requires the presence of a notary and witnesses for its validity.
Furthermore, the content of the international will can remain confidential to the testators alone, similar to the secret will.
As regards revocation, the international will follows the same general rules provided for Italian wills: it can be revoked expressly, implicitly (through the drafting of a new will) or physically (for example by destroying the document). The revocation must be registered with the Registro Generale dei Testamenti, thus ensuring that testamentary wishes are always updated.
Our Studio Legale offers support to foreigners residing in Italy for the management of international successions, ensuring that the rights of heirs are protected in compliance with Italian and international laws.
Requirements for the validity of an international will
A fundamental aspect for the validity of the international will is conservation.
This requirement ensures that the will is easily traceable and kept securely, especially in international succession contexts, where multiple legal systems may be involved.
In Italy, the Registro Generale dei Testamenti, managed by the Ministero della Giustizia, plays an essential role in the registration and traceability of wills. This register collects information both on wills drafted by persons residing in Italy and on those of Italian citizens residing abroad or of foreigners who hold assets in Italy.
Registration with the Registro Generale dei Testamenti offers a guarantee of traceability and security, fundamental for those who wish to ensure that their wishes are respected and easily identifiable after death.
Italian law requires that the notary who receives an international will provide for its registration in the Registro Generale to ensure traceability and accessibility of the document. This obligation also extends to cases in which the will is drafted by a foreign citizen residing in Italy or with property on the national territory.
Registration in the Registro Generale is particularly important when the will concerns assets located in multiple jurisdictions, since it facilitates legal cooperation between different Countries and protects the rights of heirs.
According to what is established by article 8 of legge n. 387/1990, the testator can indicate an alternative place for the conservation of the will.
This indication is then noted on the certificate that accompanies the document. Should the testator choose a location different from the notary for the custody of the will, this choice is officially registered, and the indicated place of conservation is recorded in the register, contributing to greater security and flexibility for those drafting a will with international value.
In the absence of a specific indication by the testator, the will is kept at the notary who took care of its drafting, thus ensuring future traceability of the document in legal or notarial offices. This default procedure provides additional security, especially in case of uncertainties or conflicts between heirs regarding the wishes of the deceased.
