Inheritance Disputes and Estate Succession in Greece: Key Aspects

Greek inheritance law imposes strict mandatory rules on how estates pass to heirs, regardless of what a will may say. Foreign nationals and international business owners with assets in Greece frequently underestimate the procedural complexity and the strength of forced heirship protections. This article covers the legal framework, the main dispute mechanisms, the procedural steps for accepting or renouncing an inheritance, and the strategic options available when an estate is contested.

Greece applies the Greek Civil Code (Αστικός Κώδικας, hereinafter the Civil Code) as the primary source of succession law, supplemented by the Code of Civil Procedure (Κώδικας Πολιτικής Δικονομίας). EU Succession Regulation No. 650/2012 applies to cross-border estates involving EU nationals or assets located in Greece, creating an additional layer of rules that international clients must navigate carefully. Understanding where Greek mandatory law overrides a foreign will or a foreign choice-of-law clause is the first practical step for any estate planning or dispute strategy.

Greek succession law is codified primarily in Articles 1710 to 2035 of the Civil Code. The law distinguishes between testate succession (with a valid will) and intestate succession (without a will or where the will is partially invalid). Both routes are subject to the forced heirship regime, which reserves a minimum share of the estate - the 'legitimate portion' (νόμιμη μοίρα, hereinafter the legitim) - for certain close relatives regardless of testamentary instructions.

The legitim under Article 1825 of the Civil Code equals one half of the intestate share that the protected heir would have received had no will existed. Protected heirs include descendants, the surviving spouse, and - in the absence of descendants - ascendants. A testator cannot disinherit these heirs entirely; any disposition that reduces their share below the legitim is subject to challenge through a reduction claim (αγωγή μείωσης).

Intestate succession follows a strict order of priority set out in Articles 1813 to 1824 of the Civil Code. The first class consists of descendants; the second class includes parents and siblings; the third and fourth classes cover more remote relatives. The surviving spouse participates alongside the first three classes and inherits the entire estate if no relatives of those classes exist. Greek law does not recognise common-law partnerships for intestate succession purposes, which frequently surprises foreign clients who have cohabited with a Greek partner for many years.

EU Succession Regulation No. 650/2012 applies to deaths occurring on or after August 2015. Under the Regulation, the default applicable law is the law of the state of habitual residence at the time of death. A testator may choose the law of their nationality instead. However, even where a foreign law governs the succession, Greek courts will apply Greek mandatory rules - including the legitim - as overriding provisions when assets are located in Greece or when Greek heirs are involved.

A non-obvious risk is that a will drafted under English or American law, which does not recognise forced heirship, may be partially unenforceable in Greece if Greek-situs assets are involved. International clients who own Greek real estate, bank accounts or company shares should review their estate plans specifically against Greek mandatory succession rules before any dispute arises.

Every heir in Greece faces a binary choice: accept the inheritance (with or without the benefit of inventory) or renounce it. This choice carries significant financial consequences, particularly where the estate includes debts.

Under Article 1847 of the Civil Code, an heir who accepts unconditionally becomes personally liable for all estate debts, including those exceeding the value of the assets received. Acceptance can be express or tacit; tacit acceptance occurs when an heir performs acts that unambiguously indicate an intention to accept, such as selling estate assets or paying estate debts from personal funds. A common mistake made by international heirs is taking possession of Greek property - even temporarily - without understanding that this act may constitute tacit acceptance under Greek law.

Acceptance with the benefit of inventory (αποδοχή με το ευεργέτημα της απογραφής) under Articles 1902 to 1912 of the Civil Code limits the heir's liability to the value of the inherited assets. The heir must file a declaration of acceptance with the benefit of inventory before the competent court within the statutory period and must complete a formal inventory of estate assets within four months of the declaration. Failure to complete the inventory within this deadline converts the acceptance into an unconditional one.

Renunciation (αποποίηση κληρονομίας) under Articles 1847 to 1859 of the Civil Code must be made by a formal declaration before the court of the last domicile of the deceased within four months of the heir learning of the inheritance. For heirs residing abroad or for estates involving a foreign element, this period extends to one year. Renunciation is retroactive: the renouncing heir is treated as never having been an heir, and the share passes to the next heir in line.

The procedural venue for both acceptance and renunciation declarations is the Single-Member Court of First Instance (Μονομελές Πρωτοδικείο) of the district where the deceased was last domiciled. Declarations are submitted in writing and recorded in the court's inheritance register. Electronic filing is not yet available for these declarations in most Greek courts, and personal appearance or representation by a notarised power of attorney is required.

A will may be challenged in Greek courts on several distinct grounds, each with its own procedural requirements and limitation periods.

Formal invalidity arises where the will does not comply with the mandatory form requirements of Articles 1718 to 1757 of the Civil Code. Greek law recognises three forms of will: the holographic will (ολόγραφη διαθήκη), which must be entirely handwritten and signed by the testator; the public will (δημόσια διαθήκη), executed before a notary and two witnesses; and the secret will (μυστική διαθήκη), which combines elements of both. A holographic will typed on a computer or signed by a third party is void. Courts apply these formal requirements strictly, and even minor deviations - such as a missing date on a holographic will - can render the document invalid.

Substantive invalidity arises under Articles 1758 to 1763 of the Civil Code where the testator lacked testamentary capacity at the time of execution, or where the will was procured by fraud, duress or undue influence. Proving lack of capacity typically requires medical evidence, witness testimony and, in complex cases, expert psychiatric opinion. Greek courts have developed a body of practice on assessing capacity retrospectively, particularly in cases involving elderly testators with documented cognitive decline.

The legitim reduction claim (αγωγή μείωσης) under Articles 1825 to 1838 of the Civil Code is not strictly a will contest but a separate action to restore the protected heir's minimum share. This claim is available even where the will is formally and substantively valid. The limitation period for a reduction claim is five years from the date the heir learns of the testamentary disposition that infringes the legitim, subject to an absolute outer limit of twenty years from the testator's death under Article 1835.

A practical scenario: a Greek national dies leaving a public will that bequeaths the entire estate to a charitable foundation, disinheriting two adult children. The children cannot invalidate the will on formal grounds, but each may bring a reduction claim to recover their respective legitim shares - together amounting to one half of the estate. The foundation retains the remainder. The children must act within five years of learning of the will.

A second scenario: a foreign national habitually resident in Greece dies leaving a holographic will drafted in English. The will is submitted for probate (δημοσίευση διαθήκης) before the competent Single-Member Court of First Instance. A sibling challenges the will on the ground that the testator lacked capacity due to advanced dementia. The court appoints a medical expert, reviews hospital records and hears witness testimony. Proceedings at first instance typically take between eighteen and thirty-six months depending on the complexity of the evidence.

Probate of a will in Greece is a non-contentious procedure before the Single-Member Court of First Instance. Any interested party may submit a will for probate, and the court issues a probate order (απόφαση δημοσίευσης) without adjudicating on validity. A separate contentious action must be brought to challenge validity. This two-stage structure - probate followed by a separate challenge - is a procedural nuance that surprises many foreign clients who expect a single unified proceeding.

Where no valid will exists, or where the will covers only part of the estate, Greek intestate succession rules apply. Disputes in intestate cases typically concern the identification of heirs, the existence of prior gifts that reduce the intestate share, and the valuation of estate assets.

The primary document establishing heirship in Greece is the certificate of inheritance (κληρονομητήριο) issued under Articles 1956 to 1966 of the Civil Code by the Single-Member Court of First Instance. The certificate identifies the heirs and their respective shares. It is required for most practical purposes - transferring real estate, accessing bank accounts, and registering company share transfers. Without a certificate, heirs cannot act on behalf of the estate in dealings with third parties.

Obtaining a certificate requires filing a petition supported by the death certificate, family status documents, and evidence of the absence of a will or the invalidity of any existing will. The court may require publication of a notice inviting any other potential heirs to come forward. Processing times vary considerably: straightforward cases may be resolved within three to six months, while contested applications can take significantly longer.

A non-obvious risk arises where an heir obtains a certificate based on incomplete family documentation, particularly in cases involving children born outside marriage or adopted children. Greek law under Article 1813 of the Civil Code treats legitimate, illegitimate and adopted children equally for succession purposes following constitutional amendments, but proving parentage retrospectively can require DNA evidence and separate civil status proceedings.

Disputes over the valuation of estate assets - particularly real estate and business interests - are common in intestate cases involving multiple heirs. Greek courts appoint independent valuators, but parties frequently challenge valuations, extending proceedings. The cost of valuation disputes can be disproportionate to the amounts at stake in smaller estates, making negotiated partition agreements a commercially rational alternative.

Greece's membership in the EU means that cross-border estates involving Greek assets are frequently governed by EU Succession Regulation No. 650/2012. The Regulation applies to the succession as a whole, not merely to Greek-situs assets, when the deceased was habitually resident in Greece at the time of death.

Under the Regulation, a testator who is not a Greek national but is habitually resident in Greece may choose the law of their nationality to govern the succession. This choice must be made expressly in a will or in a declaration made in the form of a disposition of property upon death. A common mistake is assuming that a will drafted under foreign law automatically constitutes a valid choice-of-law under the Regulation; the choice must be explicit and unambiguous.

Even where a foreign law is validly chosen, Greek courts retain jurisdiction to apply Greek overriding mandatory provisions. The legitim is treated by Greek courts as an overriding mandatory rule under Article 35 of the Regulation, meaning that Greek forced heirship protections apply to Greek-situs assets regardless of the chosen law. This position has been consistently maintained in Greek court practice and creates a significant constraint on estate planning for non-Greek nationals with Greek property.

The European Certificate of Succession (ECS) introduced by the Regulation is increasingly used in Greek practice to establish heirship across EU member states without the need for separate national probate proceedings in each jurisdiction. Greek notaries and courts accept the ECS as proof of heirship for the purposes of real estate transfers and bank account access. However, the ECS does not replace the Greek certificate of inheritance for all purposes, and practitioners should verify the specific requirements of each Greek authority before relying solely on the ECS.

A practical scenario: a German national habitually resident in Athens dies intestate, leaving real estate in Greece and bank accounts in Germany. The succession is governed by Greek law as the law of habitual residence. The German heirs must obtain a Greek certificate of inheritance for the Greek property and may use the ECS for the German assets. Greek inheritance tax applies to the Greek real estate, while German inheritance tax applies to the German accounts, subject to any applicable double taxation arrangements.

The risk of inaction is significant in cross-border estates: Greek real estate that remains unregistered in the heirs' names for an extended period may become subject to adverse possession claims by third parties, and the Greek land registry (Κτηματολόγιο) imposes deadlines for registration of inheritance transfers that, if missed, trigger administrative complications and additional costs.

Inheritance disputes in Greece can be resolved through litigation before the civil courts, through mediation, or through negotiated settlement agreements formalised before a notary.

Litigation is the default mechanism for contested inheritance claims. The competent court depends on the nature and value of the claim. The Single-Member Court of First Instance (Μονομελές Πρωτοδικείο) has jurisdiction over most inheritance matters, including will challenges and reduction claims. The Multi-Member Court of First Instance (Πολυμελές Πρωτοδικείο) has jurisdiction where the value of the claim exceeds the statutory threshold. Appeals lie to the Court of Appeal (Εφετείο), and further review on points of law is available before the Supreme Civil and Criminal Court (Άρειος Πάγος, hereinafter the Areios Pagos).

First-instance proceedings in contested inheritance cases typically take between two and four years, depending on the complexity of the evidence and the court's caseload. Appeals add a further one to three years. The total duration of a fully contested inheritance dispute through to a final Areios Pagos decision can exceed seven years. This timeline has significant implications for the business economics of litigation: legal fees, which typically start from the low thousands of euros for straightforward matters and can reach the mid-to-high tens of thousands for complex multi-party disputes, must be weighed against the value of the estate and the probability of success.

Mediation (διαμεσολάβηση) became mandatory as a pre-litigation step for certain civil disputes under Law 4640/2019. Inheritance disputes involving monetary claims above a specified threshold are subject to mandatory initial mediation session (MIMS) before proceedings can be filed. The MIMS must be completed within a short period - typically no more than a few weeks - and the parties are not required to reach agreement; the session merely satisfies the procedural precondition for filing. If mediation fails, litigation proceeds normally. In practice, mediation has produced settlements in a meaningful proportion of inheritance disputes, particularly where the parties are family members who wish to avoid the reputational and relational costs of prolonged litigation.

Negotiated partition agreements (συμβολαιογραφική πράξη αποδοχής και διανομής κληρονομίας) executed before a notary are the most efficient resolution mechanism where all heirs agree on the distribution of assets. The notary verifies the identity and capacity of all parties, confirms the absence of encumbrances on real estate, and registers the transfer with the land registry. Costs are generally lower than litigation, and the process can be completed within weeks once all documentation is assembled.

A common mistake made by international clients is attempting to resolve Greek inheritance disputes through foreign arbitration or foreign court proceedings. Greek courts have exclusive jurisdiction over succession matters involving Greek-situs real estate under Article 22 of the Brussels I Regulation (recast) and under Greek procedural law. Any foreign judgment purporting to transfer title to Greek real estate will not be recognised or enforced in Greece.

The loss caused by an incorrect strategy can be substantial. An heir who brings a will challenge without first securing interim measures (ασφαλιστικά μέτρα) to freeze estate assets may find that the estate has been dissipated or transferred to third parties before judgment. Greek courts can grant interim measures on an expedited basis - sometimes within days of application - but the applicant must demonstrate urgency and a prima facie case. Failure to act promptly at the outset of a dispute is one of the most costly mistakes in Greek inheritance litigation.

What happens if a foreign will conflicts with Greek forced heirship rules?

Greek courts treat the legitim as an overriding mandatory rule that applies to Greek-situs assets regardless of the law governing the succession. A foreign will that purports to disinherit a protected heir entirely will be partially unenforceable in Greece to the extent it infringes the legitim. The protected heir must bring a reduction claim before the competent Greek court within five years of learning of the infringing disposition. The foreign will remains valid for the portion of the estate that exceeds the legitim. International clients should review their estate plans against Greek mandatory rules before finalising any testamentary documents.

How long does a Greek inheritance dispute typically take, and what does it cost?

A contested will challenge or reduction claim at first instance typically takes between two and four years. If the losing party appeals, the total duration can extend to five to seven years or more. Legal fees vary considerably depending on the complexity of the case and the value of the estate; straightforward matters may involve fees starting from the low thousands of euros, while complex multi-party disputes with expert evidence can reach the mid-to-high tens of thousands. State court fees are calculated as a proportion of the value of the claim. Mediation, where available, can reduce both cost and duration significantly if the parties are willing to negotiate.

Should an heir accept a Greek inheritance unconditionally or with the benefit of inventory?

The answer depends on the composition of the estate. Where the estate includes significant debts or contingent liabilities - such as guarantees, tax arrears or pending litigation - acceptance with the benefit of inventory is strongly advisable, as it caps the heir's personal liability at the value of the assets received. Unconditional acceptance is appropriate only where the heir has a clear picture of the estate's assets and liabilities and is confident that assets exceed debts. The four-month deadline for renunciation or for filing a benefit-of-inventory declaration runs from the date the heir learns of the inheritance, not from the date of death. Missing this deadline can have irreversible financial consequences.

Greek inheritance law combines mandatory forced heirship protections, strict procedural deadlines and complex cross-border rules that create significant risks for unprepared heirs and estate planners. The legitim cannot be circumvented by will, the four-month renunciation deadline is unforgiving, and contested disputes can take years to resolve. Acting promptly, with accurate knowledge of Greek procedural requirements, is the decisive factor in protecting inheritance rights or defending an estate against unfounded claims.
