Slovakia does not recognise same-sex marriage or civil unions. However, there is some limited legal recognition for cohabiting same-sex couples, notably with regard to inheritance rights.Zák. č. 40/1964 Z. z. Občiansky zákonníkZák. č. 301/2005 Z. z. Trestný poriadok The Constitution of Slovakia has limited marriage to opposite-sex couples since 2014, and bills to allow same-sex civil partnerships have been introduced several times, most recently in 2023, but all have been rejected by the National Council of Slovakia. In May 2023, a group of lawmakers submitted a motion to the Constitutional Court to address the lack of legal recognition for same-sex couples, while a separate proceeding, initiated in March 2022, focuses on the refusal of Slovak authorities to grant permanent residency to the foreign same-sex spouses of Slovak citizens. The Constitutional Court accepted both petitions for review, but has yet to issue a final ruling.

In June 2018, the European Court of Justice (ECJ) ruled that the same-sex spouses of European Union citizens should be granted a right of residency in Slovakia. Slovak authorities announced that they would comply with the ruling.JUDGMENT OF THE COURT (Grand Chamber) 5 June 2018 However, according to media reports, as of April 2026, foreign same-sex spouses were still unable to meet residency requirements because family law requires spouses to possess a valid marriage license, and marriage under Slovak law is defined as "a union between a man and a woman". The ECJ expanded on the previous ruling on 22 November 2025, when it ruled in Jakub Cupriak-Trojan and Mateusz Trojan v Wojewoda Mazowiecki, a Polish case, that all member states of the European Union must recognise same-sex marriages validly performed within the European Union.

Limited legal rights Since 2018, Slovak civil and penal law has recognised a new definition of a "close person" (), previously limited to a sibling, relative or spouse. A family member or a person in a relationship shall be considered under law as a "close person" "if an injury suffered by one of them is reasonably felt by the other person as an injury suffered by him or her." Only limited rights are granted, namely in the area of inheritance. While the provision theoretically includes same-sex unions, it may be more difficult for these couples to prove their relationships and have their rights guaranteed.

In 2023, Minister of Justice Viliam Karas introduced a cohabitation bill to the National Council, which was approved at first reading in a 72–21 vote in May. However, later that same month, Jana Dubovcová, who succeeded Karas as minister of justice on 15 May, withdrew the legislative proposal due to criticism from LGBT organizations.

Registered partnerships Background In 2008 and 2009, the Otherness Initiative (), an LGBT advocacy group, launched a public awareness campaign for the recognition of same-sex registered partnerships (, ). Previously, bills to recognise same-sex civil partnerships had been defeated in 1997 and 2000. In January 2008, activists met with Deputy Prime Minister Dušan Čaplovič to discuss proposed partnership legislation. also held a number of public discussions about registered partnerships throughout 2008.Iniciatíva Inakosť During this time, the Green Party announced its support for registered partnerships for same-sex and opposite-sex couples.7 bodov pre krajšie a zdravšie Slovensko "podpora registrovaných partnerstiev medzi ľuďmi rozdielneho aj rovnakého pohlavia"

As a member of the Council of Europe, Slovakia falls under the jurisdiction of the European Court of Human Rights (ECHR). In January 2023, the Grand Chamber of the European Court of Human Rights ruled in Fedotova and Others v. Russia that Article 8 of the European Convention on Human Rights, which guarantees a right to private and family life, imposes a positive obligation on all member states of the Council of Europe to establish a legal framework recognising same-sex partnerships. The ECHR has also issued similar rulings with respect to Romania in Buhuceanu and Others, Ukraine in Maymulakhin and Markiv, Bulgaria in Koilova and Babulkova, and Poland in Przybyszewska and Others.

The bill was supported by 50 MPs with 37 opposed, but failed as it required 76 votes to pass. President Zuzana Čaputová criticized the bill's defeat, saying, "We need to act. Our society is not threatened by the love of two people of the same sex or their partnership." The Catholic Church opposed the legislation, and was widely criticized by civil society after Archbishop Ján Orosch said that the two victims of the terrorist attack were "steeped in immoral behaviour" and "should not have been referred to as innocent".

In 2023, registered partnerships were opposed by most Slovak political parties represented in the National Council, including For the People, the Christian Union, People's Party Our Slovakia, Ordinary People and Independent Personalities, Direction – Social Democracy, and We Are Family.OĽaNO nevstúpi do koalície, ktorá rieši drogy a registrované partnerstvá.
