First marriages in Tilos In 2008, the LGBT rights group OLKE announced its intention to sue
municipalities that refused to marry same-sex couples, pointing out a loophole in the 1982 law that legalized
civil marriage between "persons", without reference to
gender. On 3 June 2008, Mayor Anastasios Aliferis of
Tilos married two same-sex couples, two lesbians and two gay men, citing the legal loophole. He was heavily criticized by clergymen of the
Church of Greece, which in the past had also opposed the introduction of heterosexual civil marriage, the original intent of the 1982 law.
Justice Minister Sotirios Hatzigakis declared the Tilos marriages "invalid" and
Supreme Court prosecutor Georgios Sanidas warned Aliferis of the legal repercussions of his "breach of duty", but he said he had "no intention of annulling the marriages". Government officials filed a court motion to annul the two same-sex marriages, triggering demonstrations and protests among the LGBT community. A hearing in the case by a court of appeal was held on 14 January 2011. The court issued a decision invalidating both marriages on 14 April 2011. On 30 November 2017, this ruling was upheld by the Supreme Court. The couples subsequently announced their intention to sue Greece at the
European Court of Human Rights (ECHR).
Tsipras governments Syriza, the main party in Greece's coalition governments from 2015 to 2019 under Prime Minister
Alexis Tsipras, had promised to legalize same-sex marriage as part of its September 2015 campaign platform, though no legislation was ever proposed. On 10 June 2019, a few weeks ahead of the
parliamentary election held on 7 July 2019, Tsipras repeated the promise, stating that his party would push through same-sex marriage legislation if it won the election. However, his party was not re-elected.
Passage of legislation in 2024 On 17 March 2021, Prime Minister Mitsotakis formed a committee mandated to prepare a national strategy for LGBT equality. The committee was chaired by
Linos-Alexandre Sicilianos, a former president of the ECHR. Its members included experts in family and constitutional law, representatives of civil society including spokespeople from the Transgender Support Association, Thessaloniki Pride and the Rainbow Families of Greece, as well as several government officials. On 29 June 2021, the committee presented the national strategy to Mitsotakis, which included a section addressing same-sex marriage. A dedicated team within the Prime Minister's office was subsequently formed to develop an action plan based on the strategy's recommendations. Numerous meetings were held with relevant ministries, and the plan's proposals were integrated into their respective annual action plans. As a result of these policies,
ILGA-Europe raised Greece's score on its "Rainbow Map" from 47% in 2021 to 57% in 2023, ranking the country 13th in
Europe. In June 2022, Syriza lawmakers introduced a same-sex marriage bill to the Hellenic Parliament, however, Syriza was not elected. In July 2023, Prime Minister Kyriakos Mitsotakis, whose
New Democracy party was re-elected in the
June 2023 election, announced his
government's intention to legalize same-sex marriage. In an interview with
Bloomberg Television, Mitsotakis added that "Greek society is much more ready and mature." In September,
Kathimerini reported that a draft bill legalizing same-sex marriage was expected to be introduced to Parliament "in the coming months". The bill would define marriage as the union of "two persons of the same or different sex", and guarantee all the rights and obligations of marriage to married spouses irrespective of
sexual orientation. Mitsotakis also said New Democracy MPs would be granted a
conscience vote. In November 2023, media reported that the government was "finalising" the bill. In December, the
monastic community of Mount Athos expressed its opposition to the bill. The Church of Greece also released a statement opposing the proposed bill. It also expressed its opposition to adoption by same-sex couples and argued that children "are being treated as 'accessories' and 'companion pets' for gay couples". Government spokesman Pavlos Marinakis reacted to the statement, "We always listen to the opinions of the Church with respect. But at the same time, we are implementing our policy, and will listen to the views of society, civil society, the citizenry, institutions, and parties in total." An
opinion poll conducted in December showed that 52% of Greek citizens supported same-sex marriage. Prime Minister Mitsotakis confirmed the government's intention to legalize same-sex marriage and adoption on 10 January, adding that he hoped to have the bill approved before Easter. On 11 January,
Stefanos Kasselakis announced his support for the government bill despite its "imperfections" on parental rights, and said he would instruct all Syriza lawmakers to vote for the proposal, though some Syriza MPs eventually did not vote for the bill. The government ruled out holding a referendum on the issue on 19 January. A public consultation period lasted from 25 January until 31 January, with the bill being introduced to Parliament on 1 February by
Minister of State Akis Skertsos. A final vote on the legislation took place on 15 February with the bill passing by 176 votes to 76. It was signed into law by President
Katerina Sakellaropoulou and took effect upon publication in the
Government Gazette on 16 February 2024 (
Law 5089/2024). According to some analysts, the backlash from this event was a contributing factor in Sakellaropoulou not being nominated for a second term. The first same-sex marriage took place in
Nea Smyrni,
South Athens on 2 March 2024 between Stavros Gavriliadis and Dimitris Elefsiniotis. The law amended article 1350 of the Greek Civil Code to state:
Marriage shall be contracted between two persons of different or the same sex. In addition to granting same-sex couples full adoption rights, the law also recognizes their parental rights over children born abroad. Three religious organisations subsequently challenged the new law at the
Council of State, arguing that the legalisation of same-sex marriage "alter[ed] the traditional concept of family and disadvantage[d] adopted children". The Council ruled 21–6 on 30 May 2025 that the law was constitutional and dismissed the lawsuit. It found that the marriage law "complies with constitutional provisions regarding equality and the protection of marriage, family, motherhood, and childhood". The court decision was officially published on 20 March 2026.
Statistics More than 400 same-sex marriages had taken place in Greece by February 2025, of which around 65% were between two men.
Religious performance The
Church of Greece strongly opposes same-sex unions. Although the majority of Greeks (who are mostly Christian) support same-sex marriage according to opinion polls, the Church of Greece, along with the
Catholic Church and the
Greek Orthodox Church, continue to oppose it. In early February 2024, an encyclical read out at Orthodox churches at a Sunday morning liturgy opposed measures it said would "promote the abolition of fatherhood and motherhood… and put the sexual choices of homosexual adults above the interests of future children". The Church of Greece campaigned heavily against legalization in 2024, issuing a statement in January: "This legislation conflicts with both Christian anthropology and with society's duty to ensure children's well-being and proper upbringing, but also with the children's right to have a paternal and maternal presence and care. For all those reasons, and with a sense of pastoral responsibility and love, our Holy Church is strongly opposed to the proposed bill." Further, Archbishop
Ieronymos II of Athens reiterated the Church's opposition to civil marriage regardless of gender and called for a referendum on the legalization of same-sex marriage. Representatives of the
monastic community of Mount Athos also expressed opposition to the same-sex marriage law, which does not apply to the autonomous region as it has its own sovereignty within Greece and the European Union. ==Public opinion==
