Indonesia is a unitary republic whose 1945 Constitution, revised to 2002, has a human rights chapter (Arts. 28A to 28J) and a Constitutional Court that reviews statutes against it (Art. 24C). Criminal law has just been recodified: Law No. 1 of 2023 on the Criminal Code was enacted on 2 January 2023 and took effect three years later, on 2 January 2026, and Law No. 1 of 2026, enacted on the same date, adjusted the penalties of statutes outside the Code, rewriting among others the fines of the Domestic Violence Elimination Law and the articles on the death penalty. Aceh is a separate regime: Law No. 11 of 2006 applies Islamic law, including criminal law (jinayah), to Muslims through the Syar'iyah Court (Arts. 125 to 129 and elucidation of Art. 128(2)), and the Criminal Code lets local 'living law' make an act punishable where that law lives and the Code is silent (Art. 2). The statutes are issued in Indonesian, and the official copies used for this guide were read in the legal database of the Audit Board (peraturan.bpk.go.id), which also states whether each text is still in force.

The Marriage Law (Law No. 1 of 1974) defines marriage as a bond between a man and a woman with the aim of a happy and lasting family founded on belief in one God (Art. 1); a marriage is valid when performed under the law of each party's religion or belief, and every marriage must be registered (Art. 2). In principle a man may have one wife and a woman one husband, but a court may allow a husband to take more than one wife where the wife cannot perform her duties, has an incurable disability or illness, or cannot bear children, and only with the wife's consent and proof that he can provide for them and treat them fairly (Arts. 3 to 5). Since Law No. 16 of 2019 both sexes must be 19 to marry, and a court may grant a dispensation on very urgent grounds after hearing both intended spouses (Art. 7). Violence in the family has a dedicated statute, Law No. 23 of 2004, and sexual violence another, Law No. 12 of 2022, which counts child marriage and forced marriage among its offences (Art. 10).

For couples with a foreign partner, a marriage abroad between an Indonesian and a foreigner is valid if it follows the law of the country where it took place and does not breach the Marriage Law, and the marriage certificate must be registered at the marriage registry of the couple's place of residence within one year of their return to Indonesia (Art. 56). A mixed marriage, defined as one between persons subject to different laws because of different nationality, one of them Indonesian (Art. 57), cannot take place until a certificate shows that each party meets the conditions of his or her own law; if the official refuses the certificate, the court decides without appeal (Art. 60). Children born in a lawful marriage between an Indonesian and a foreign parent are Indonesian citizens, but a child with dual nationality must choose one on turning 18 or marrying, by a written statement within three years (Citizenship Law No. 12 of 2006, Arts. 4(c) and (d) and 6), and an adult Indonesian who voluntarily acquires another nationality loses Indonesian citizenship (Art. 23(a)). Visitors and residents should also know two provisions of the new Criminal Code: sexual intercourse with a person who is not one's spouse is punishable by up to one year or a category II fine (Art. 411) and living together as spouses outside marriage by up to six months or a category II fine (Art. 412), but both can be prosecuted only on the complaint of a spouse or, for unmarried persons, of parents or children, and the complaint can be withdrawn until the trial begins.

Fundamental rights

Chapter XA of the Constitution protects the right to life (Art. 28A), the right to form a family through lawful marriage and the child's right to protection from violence and discrimination (Art. 28B), equality before the law (Art. 28D), protection of person, family, honour and dignity and freedom from torture (Art. 28G) and the right to medical care and social security (Art. 28H). Art. 28I(1) lists rights that cannot be reduced in any circumstances, among them life, freedom from torture, freedom of thought, religion and protection from retroactive laws, while Art. 28J(2) allows other rights to be limited by law to protect the rights of others and to meet morality, religious values, security and public order. Art. 29 guarantees freedom of worship, and Art. 24C gives the Constitutional Court, of nine justices, first and final jurisdiction to review statutes against the Constitution. The text consulted is the 1945 Constitution as revised to 2002.

Komnas HAM, the National Human Rights Commission, was set up by Law No. 39 of 1999, with its seat in the capital (Art. 76(3)). Any person or group with strong grounds to believe a right has been violated may file a written or oral complaint, which is served only if it carries the complainant's true identity and initial evidence (Art. 90(1) and (2)); a complaint filed by another person needs the victim's consent, except in certain violations judged by Komnas HAM (Art. 90(3)). The Commission does not examine, or stops examining, a complaint without adequate initial evidence, outside human rights, brought in bad faith, where a more effective remedy exists or while another legal remedy is under way (Art. 91(1)). Hearings are closed unless it decides otherwise (Art. 93), and a mediated settlement is a written agreement, legally binding and valid evidence, which the district court can be asked to enforce (Art. 96(2) to (4)).

The United Nations Treaty Collection records these dates for Indonesia: Convention on the Elimination of All Forms of Discrimination against Women, signed 29 July 1980 and ratified 13 September 1984; Convention on the Rights of the Child, signed 26 January 1990 and ratified 5 September 1990; Convention against Torture, signed 23 October 1985 and ratified 28 October 1998; Convention on the Elimination of All Forms of Racial Discrimination, acceded 25 June 1999; the International Covenant on Civil and Political Rights and the Covenant on Economic, Social and Cultural Rights, both acceded 23 February 2006; and the Convention on the Rights of Persons with Disabilities, signed 30 March 2007 and ratified 30 November 2011. The Optional Protocol to the women's convention shows only a signature, on 28 February 2000, and Indonesia does not appear among the parties to the Second Optional Protocol to the Civil and Political Covenant on abolishing the death penalty.

The death penalty remains in law but is hedged. Under the Criminal Code it is a last-resort sentence always threatened as an alternative (Art. 98). Since Law No. 1 of 2026 rewrote Arts. 99 to 101, a judge imposes it with a ten-year probation period (Art. 100(1)); it cannot be carried out during that period (Art. 100(6)); if the convict shows commendable conduct it is changed to life imprisonment by presidential decree after the Supreme Court's opinion (Art. 100(4)); and it can be carried out only if the convict's conduct during probation was not commendable and either no clemency was requested or the President refused it (Art. 99(1)). If clemency is refused and nothing happens for ten years, the sentence becomes life imprisonment by operation of law (Art. 101). Execution is by firing squad, not in public, and is postponed for a pregnant or breastfeeding woman or a person with a mental illness (Art. 99(2) to (4)). Amnesty International lists Indonesia as retaining the death penalty in law.

The Code also writes local custom into criminal law. Art. 2 preserves 'living law' that makes an act punishable even if the Code does not provide for it, but only in the place where that law lives, only if the Code is silent, and only if it conforms to Pancasila, the Constitution, human rights and general principles recognised by nations (Art. 2(1) and (2)); the Code lets a judge impose compliance with local customary obligations as an additional penalty, treated as equal to a category II fine (Arts. 96 and 97). Aceh adds a separate regime: Law No. 11 of 2006 applies Islamic law, including criminal law (jinayah), to Muslims through the Syar'iyah Court (Arts. 125 to 129).

In practice

  • To complain of a human rights violation, write to or approach Komnas HAM with your true identity and initial evidence; if you act for another person, bring the victim's consent (Law No. 39 of 1999 Art. 90).
  • Check first whether a more effective remedy exists or a legal process is under way: Komnas HAM does not examine, or stops examining, in either case (Art. 91(1)(d) and (e)).
  • If mediation succeeds, ask the Commission to put the settlement in writing: it is binding and valid evidence, and if a party does not comply the other may ask the district court to enforce it (Art. 96).
  • To challenge a statute's compatibility with the Constitution, the route is the Constitutional Court (Art. 24C); the procedure for filing is not covered here.

Recent changes

Law No. 1 of 2026, enacted on 2 January 2026, rewrote Arts. 99 to 101 of the Criminal Code, so that the death sentence is imposed with a ten-year probation period during which it cannot be carried out.

Where to go

  • Komnas HAM, which sits in the capital and may have representatives in the regions (Law No. 39 of 1999 Art. 76(3) and (4)).
  • Constitutional Court (Mahkamah Konstitusi), for review of statutes against the 1945 Constitution.
  • Komnas Perempuan, Jalan Latuharhary No. 4B, Menteng, Central Jakarta; telephone +62-21-3903963.

Worth knowing

Art. 28J(2) subjects the rights of Chapter XA to limits set by law, and Art. 2 of the Criminal Code keeps 'living law' alive locally; both mean the national text must be read with local custom and, in Aceh, with the qanuns that apply to Muslims.

Frequently asked questions

Does Indonesia still have the death penalty?

Yes: Art. 98 of the Criminal Code keeps it as an alternative last-resort sentence, imposed with a ten-year probation period during which it cannot be carried out (Art. 100 as rewritten by Law No. 1 of 2026), and Indonesia is not a party to the Second Optional Protocol to the Civil and Political Covenant.

Where can I complain about a human rights violation?

To Komnas HAM, orally or in writing, with your identity and initial evidence (Law No. 39 of 1999 Art. 90), unless a more effective remedy exists or a legal process is under way (Art. 91).

Which international human rights treaties has Indonesia joined?

The UN Treaty Collection lists CEDAW (1984), the Convention on the Rights of the Child (1990), the Convention against Torture (1998), the racial discrimination convention (1999), both Covenants (2006) and the disability convention (2011).
