An international couple can marry legally in Korea by filing a marriage report at a local government office, and according to SeoulStart’s guide the filing itself carries no fee. The costs that actually add up sit around it: home-country documents, translations, and any wedding services you book. The eligibility test for the foreign partner is mostly about proving, with documents from their own country, that they are free to marry.
Who is eligible to marry
Songpa-gu Office’s English page says that when an international couple registers a marriage in Korea, the foreign national must provide documents proving nationality (a passport copy, family register, birth certificate or identity register, for example) and proof, issued by a government office or embassy, that they meet the legal requirements to marry under their home country’s law.
In practice that means a document often called a certificate of no impediment or an affidavit of eligibility to marry. SeoulStart’s guide lists different names for it by country, such as “Certificate of Marital Status” for Vietnam and “Legal Capacity to Contract Marriage” for the Philippines. Dongdaemun-gu’s page calls it the foreign spouse’s affidavit of eligibility for marriage and asks for the original with a Korean translation.
SeoulStart also states that two adult witnesses are needed, each aged 19 or older, and that same-sex marriages are not currently recognised for registration in Korea. Ask your local office to confirm both points.
What the registration costs
SeoulStart says there is no filing fee and that a marriage certificate costs about 1,000 won when issued separately. Treat these as typical figures rather than guarantees, because fees can differ by office and document. The real expense is usually time and the documents behind the form.
Document costs to budget for
SeoulStart’s guide to home-country documents describes authentication by apostille for countries that belong to the Hague apostille system, and consular legalisation for those that do not. It adds that the Korean translation must be signed by the translator, while a government certification of the translation is not legally required. Dongdaemun-gu’s page says translations must include the translator’s personal information and signature.
Costs and timing depend on your country. The same guide gives one example: for a US citizen, an affidavit can be notarised at the embassy in Seoul for a fee of 50 US dollars, while it lists several weeks for some other countries. For other nationalities, it says to contact the embassy for fees. It also notes that Korean law does not set one fixed validity window for the certificate and that district offices apply their own practice, so ask the specific office before ordering documents. For Vietnamese readers, the guide says the route for the certificate of marital status was changing from consular legalisation to apostille on September 11, 2026; confirm the current route with the Vietnamese embassy and the Korean office.
Add to the budget: translation, courier costs, and possibly time off work for appointments. Do not assume numbers from another couple’s route apply to yours.
Wedding service costs: where couples overspend
A ceremony is optional and separate from the legal marriage, according to SeoulStart. If you do book wedding services, consumer authorities have flagged this area. Asiae reports that dispute-resolution requests about wedding services rose from 905 to 1,076 cases, and that about 88.1 percent of complaints involved cancellation, penalty fees or withdrawal of offers.
The Economist (Korea) reports on a Fair Trade Commission action against wedding preparation agencies. It says that essential items such as photo files and dress fitting fees were being sold as separate options, and that a survey found customers paid on average 1.44 million won more than their first quote. The commission’s standard terms now put such items in base services, according to Seoul Shinmun.
Practical steps drawn from these reports:
- Ask for base services and add-ons priced separately, in writing.
- Compare prices on the Korea Consumer Agency’s Chamgagyeok (참가격) site, which Asiae mentions.
- Read the refund and penalty table before paying a deposit.
- Keep the contract and all receipts.
If the foreign spouse plans to live in Korea
SeoulStart states that registering with a Korean national can open the F-6-1 spouse visa route, and lists a minimum income for the Korean spouse of 25,195,752 won for a two-person household and a basic Korean-language requirement, both waived if the couple has a child together. This is a secondary source and the thresholds are the kind of figure that is updated, so confirm them with the Ministry of Justice’s immigration service before relying on them. Budget separately for visa-related documents and any language test.
A budgeting checklist
- Ask the local office which home-country document it requires and how recent it must be.
- List each document with its authentication route and likely lead time.
- Get a quote for a signed Korean translation.
- Decide whether you want a wedding event at all, and set a ceiling before collecting quotes.
- Check the visa conditions for the foreign spouse if they will live in Korea.
Common mistakes and what to verify
- Confusing the ceremony with the legal marriage. The report is what registers the marriage.
- Ordering a certificate before asking how long the office accepts it.
- Submitting translations without the translator’s details.
- Signing a wedding package that lists optional charges without amounts.
- Using a visa income figure from an old blog post.
Rules change: confirm with the official body
This is general information, not legal or financial advice. Requirements, fees and thresholds vary by office and change over time. Confirm the current rules with the district office where you will file, your embassy, the immigration service (HiKorea), and the Korea Consumer Agency for wedding-service contracts.
