Do I need to register our marriage in Korea and in my home country?

In most cases, yes. Korea treats a marriage as existing only once it is reported to a Korean family registration office (혼인신고), and your home country normally keeps its own civil records that Korea does not update for you. If only one side has the marriage on file, you are married in one country and single in the other. That gap is what blocks a marriage migrant visa, confuses a child's birth registration, and causes trouble years later in a divorce or an inheritance. Plan both registrations from the start, and check which order your embassy expects.

Which country's law decides whether we are validly married?

The Korean conflict-of-laws statute, the Private International Act (국제사법), looks at two separate things.

• Who may marry (age, not already married, no close family tie) is checked for each spouse under that spouse's own national law. You must qualify under your law, and your partner under theirs.
• The formalities are valid if they meet the rules of the country where the ceremony or registration happens, or the rules of either partner's nationality. There is one exception that matters to most couples reading this: if you marry inside Korea and one of you is a Korean national, only the Korean form counts, which means the report at a Korean office.

If a spouse holds Korean nationality together with another one, Korea looks only at the Korean one for this purpose.

Where and who	What makes the marriage valid in Korea
In Korea, one spouse Korean	A report at a Korean office. A wedding ceremony or a religious blessing alone is not enough
Abroad, one spouse Korean	The form used in that country, followed by a report of the existing marriage to the Korean records
In Korea, both spouses foreign	The Korean report or the form of either spouse's national law, such as registration at an embassy

What does the Korean office check before it accepts the report?

The office must accept the report unless the marriage breaks a legal rule. Under the Civil Act (민법), both of you must be at least 18, neither may still be married to someone else, and you must not be close relatives within the listed degrees. The form has to be signed by both spouses and two adult witnesses.

For the foreign spouse the office also needs proof that your own country lets you marry. Expect to bring:

1. your passport, and your alien registration card (외국인등록증) if you have one
2. a certificate of your capacity or eligibility to marry (혼인요건구비증명서) or a similar document, usually issued by your embassy in Korea
3. a Korean translation of every foreign document, with the translator's name and contact details
4. an apostille or consular legalisation on documents issued in your home country, depending on which treaty your country has joined

Make sure your name is spelled exactly as in your passport on every page. A missing middle name or a different transliteration is one of the most common reasons a file comes back.

In which order should we register?

There is no single correct order. It depends on what your home country requires.

• Korea first. You report at a Korean office, receive the Korean marriage certificate (혼인관계증명서), and then register it at your embassy or at home. Some countries accept this easily.
• Home country first. The wedding is registered under your home country's rules first. After that, the Korean partner files it with the Korean registry, following the registration statute (가족관계의 등록 등에 관한 법률). Some embassies prefer this, and some countries do not register a marriage formed abroad without extra steps.

Ask your embassy in writing which documents it wants and whether it needs the Korean certificate translated and apostilled. Write down the date you file in each country.

What goes wrong if only one country has it on record?

The visa is usually the first problem. To issue a marriage migrant visa (결혼이민, F-6) for living together, the Korean spouse must invite you and becomes your guarantor, and the consulate may check whether the marriage has been formed under the laws of the countries concerned. A marriage known in only one place may fail that check.

Other gaps appear later:

• Your home country still shows you as unmarried, so a later marriage there would be a second marriage. Korea forbids a person who is already married from marrying again, and such a marriage can be annulled through the court.
• Registering a child at your embassy, or getting the child a passport from your country, may require the marriage to be on your country's records first.
• When the marriage ends, a Korean divorce does not change your home records by itself, and a divorce at home does not change the Korean ones.

Is a marriage registered only for the visa a problem?

Yes, and a serious one. A marriage with no real agreement to live as spouses is void under the Civil Act. Lying to an official so that the register records a sham marriage is also punishable under the Criminal Act (형법): the ceiling is 5 years in prison or a 10 million won fine. Consulates look at how you met and whether you both intend to marry, and a refused applicant generally has to wait 6 months before applying again, unless there is an urgent reason such as a birth.

If someone offers to arrange a marriage "just for papers", walk away.

What if my Korean is not good enough to fill in the forms?

The forms are in Korean, and the office does not have to provide an interpreter for you. Take a friend or a professional translator, read every box before you sign, and ask for a copy of what you hand in. Never sign a blank form for your spouse or a broker to complete later.

Next step

Before you file anywhere, list what each country will ask for, how long each document stays valid, and who will translate it. If your case involves a past marriage, a divorce abroad, or dual nationality, have it checked first. Consultations are paid; when you contact us, a staff member will call you back and explain the fee.
