SORA RENTAL NOTE · 33
I am 18. Can I sign a Korean lease without a parent?
For a foreign student, legal capacity cannot be decided from age or the Korean age of majority alone.
Content checked · 3 October 2026
The key points
- Korean private international law generally looks to the person’s national law to determine legal capacity.
- Do not assume that every 18-year-old foreign student has the same ability to sign independently.
- Check applicable law and any necessary consent before paying or signing; a parent paying is not automatically a guarantor.

I’m 18 and starting university. Can I sign on my own?
Let’s discuss the contract with your parents before committing.
We must check your national law and whether consent is needed.
Sign only after capacity and any necessary documents have been checked.
University admission does not settle legal capacity
- Age and applicable law
- Legal capacity
Being admitted to university, living independently or holding a student visa does not by itself answer whether you can enter a binding lease without consent. Legal capacity concerns whether you can carry out the transaction on your own. For a foreign tenant, the legal analysis can cross more than one country’s law.
Article 28 of Korea’s Act on Private International Law says a person’s capacity is generally governed by their national law. It is therefore unsafe to apply one Korean age threshold to every international student. Give the adviser your actual date of birth and nationality, rather than relying on school year, appearance or an informal description of age.
An exception needs facts, not a quick assumption
- Legal requirements
- What happened
- Consent
Article 29 protects certain transactions when both parties are in the same country when the transaction is made: someone lacking capacity under their national law may be unable to rely on that lack of capacity if they have capacity under the law of that country. The exception has conditions, including what the other party knew or could have known.
This does not mean “all foreign students can sign in Korea.” Nor should the same result be assumed for a student signing remotely from another country. Nationality questions, laws differing within a country and the circumstances of signature may need individual review. Ask for a legal assessment if capacity is uncertain.
Clarify consent, signatures and financial responsibility
- Guardian consent
- Signature
- Duties to the landlord
Before committing money, establish whether consent or representation is legally necessary and, if so, who can provide it and in what form. Ask what identity, relationship or supporting documents the recipient needs. A generic online consent template or a parent’s informal message may not resolve the applicable legal requirements.
Also separate the roles on the paperwork. The student as tenant, a parent giving consent, a person acting as representative and a guarantor are different roles. Do not add a parent as guarantor simply because they are helping with funds. Read and agree on any guarantee or additional obligation separately before anyone signs.
What to check
- Confirm the student’s exact birth date, nationality and signature location.
- Check the applicable capacity rules, rather than assuming a universal age threshold.
- If consent or representation is required, verify the correct person, form and supporting papers.
- Keep consent, tenancy and any guarantee obligations clearly separated in the documents.
Common questions
My parent sends the deposit. Does that prove they consented to every term?
Do not assume so. Payment, legally effective consent and a guarantee are distinct issues. Confirm the necessary consent and any additional obligations explicitly.
Can I sign first and cancel later by saying I was too young?
Do not rely on that. Applicable national law, the transaction-protection rule and the facts may affect the result. Resolve capacity before signing rather than treating age as an automatic cancellation right.
