After the wedding is over, a surprising number of couples discover they are not sure which of their documents is the official one. People use the terms buku nikah, akta nikah, and kartu nikah interchangeably in everyday conversation, but they are not the same thing. Getting this wrong means extra trips to different government offices. This article explains each one in plain language. This is general information, not legal advice. Always confirm current requirements with the relevant office.
Three Documents That Are Commonly Confused
The Marriage Book (Buku Nikah)
The buku nikah is issued by the KUA (Kantor Urusan Agama, the Office of Religious Affairs) for Muslim marriages. Its official name is kutipan akta nikah, meaning an extract of the marriage register. Couples typically receive two books, one for each spouse. It contains the names of both parties, the date of the contract, the wali (guardian), and the witnesses. This is the document most commonly requested for administrative purposes after the wedding.
The Marriage Record (Akta Nikah)
The akta nikah is the official record of the marriage as held in the state register. The buku nikah you hold is an extract of this record, so the two are not competing documents but related ones. For non-Muslim marriages, the equivalent is called an akta perkawinan, issued by the civil registry office (Dukcapil). According to Hukumonline (27 February 2024), the KUA handles Muslim marriages while non-Muslim marriages are recorded by a civil registry officer at the Dukcapil office.
The Marriage Card (Kartu Nikah)
The kartu nikah is a card-sized document introduced by the Ministry of Religious Affairs as a supplement to the buku nikah. Based on reporting by NU Online (November 2018) and Bisnis.com, it was never intended to replace the buku nikah. A digital version is also available through the Simkah Web system. Availability varies by KUA and by period, so always ask your KUA directly, and never treat the kartu nikah as your primary proof of marriage.
| Document | Issuer and primary purpose |
| Buku nikah (kutipan akta nikah) | Issued by KUA for Muslim marriages. Primary proof of marriage recorded by the state. |
| Akta nikah (in the register) | Official marriage record. The buku nikah is your extract of this record. |
| Akta perkawinan | Issued by Dukcapil for non-Muslim marriages. Primary proof of state registration. |
| Kartu nikah | From the Ministry of Religious Affairs via KUA. A supplement, not a replacement for the buku nikah. |
Which Document Is Used for What
In practice, it is the buku nikah or the akta perkawinan that gets requested most often. The kartu nikah will only come up if an institution specifically asks for it. The list below is a general guide; individual institutions may have different requirements.
- Updating your family card (kartu keluarga) and national ID: your marital status is updated using the buku nikah or akta perkawinan.
- Passport or visa applications: some immigration offices and embassies require proof of marriage, especially if you are changing your name or traveling together.
- Joint mortgage applications: banks generally require marriage documentation to assess combined income.
- Adding a spouse as a dependent: insurance providers, BPJS, and employer benefits usually require a copy.
- Registering a child’s birth: parents who are legally married will be asked to show their marriage document.
For Non-Muslim Couples: The Akta Perkawinan from Dukcapil
Non-Muslim couples do not register at the KUA, so they do not receive a buku nikah. Their official document is the akta perkawinan from the Dukcapil office. The process has two separate steps: the religious blessing or sanctification, then the state registration.
Religious Blessing and State Registration Are Two Separate Things
A church ceremony, temple blessing, or other religious sanctification makes the marriage valid under your religion. After that, the marriage must be reported to Dukcapil so it is recorded by the state. Because these are separate steps, make sure the registration does not slip through the cracks once the celebration is over.
General Requirements and Reporting Deadline
According to information from Dukcapil Kemendagri published by detikNews on 31 March 2026, general requirements for an akta perkawinan include a letter of marriage from a religious official, both spouses’ e-KTP, family card, and a color photo of the couple. Reporting is stated to be due within 60 days of the marriage, under Law Number 24 of 2013. If you miss the deadline, registration is still possible but usually requires additional documents or verification. Always confirm the current requirements with your local Dukcapil office, since procedures vary by region and may change.
Documents to Update After Getting Married
Having your buku nikah or akta perkawinan is only the first step. Update these records as well:
- Family card (kartu keluarga): create or merge cards based on your domicile.
- National ID (KTP): update your marital status, and address if you are moving.
- Passport: if you are changing your name, check with the immigration office what is required.
- Bank accounts, insurance, and BPJS: add your spouse as a beneficiary or dependent if needed.
- NPWP (tax identification): ask your tax office whether your marital status needs to be updated.
How to Check and Safeguard Your Documents
Marriage documents tend to be ignored until they are urgently needed. A few simple habits prevent that scramble.
Check the Details as Soon as You Receive Them
Verify the spelling of names, dates of birth, ID numbers, and the wedding date the moment the document is in your hands. Errors are much easier to correct when they are new.
Keep Originals and Copies Separately
Store the original in a secure place and keep both physical and digital copies somewhere separate. If an institution asks for a certified copy, ask where and how to get one, since the process differs by office.
Know What You Actually Received
If you are unsure whether the document you brought home is the buku nikah, an extract of the register, or simply a letter from a place of worship, ask the issuing officer. A religious letter is not the same as state registration.
Marriage Documents for Couples Getting Married in Bali
Many couples who marry in Bali are based in other cities, so document planning needs to start early, not after the event. On weddings accompanied by Mara Bali Wedding (marabaliwedding.com), the team forwards the couple’s documents and the couple receives a religious marriage certificate on the wedding day. That religious certificate is separate from the state registration described above, so couples still need to handle their own registration through KUA or Dukcapil according to their religion and home domicile.
For couples whose ID cards are registered outside Bali, the timing and location of registration can be different from the wedding date. Read When to Register Your Marriage If You Are Getting Married Outside Your Home City to understand how that works.
Conclusion
The buku nikah, akta nikah, and kartu nikah are not three competing documents. The buku nikah is an extract of the marriage register for Muslim couples; the akta perkawinan is the state registration document for non-Muslim couples from Dukcapil; and the kartu nikah is a supplementary card that does not replace either. Start by confirming which registration applies to your religion, handle it on time, and then update your other identity documents. Always confirm current requirements with your local KUA or Dukcapil.
