We advise international couples with ties to Korea who are considering marriage to consider a Korean-legal prenuptial agreement that is enforceable in both Korea and abroad. Many misunderstandings are prevalent online (even from Korean law firms) on the usefulness of prenuptial agreements in Korean divorce proceedings. The reality is that even if all clauses in a prenuptial agreement are not enforceable in Korean courts, the fact remains that Korean courts, at least, consider these agreements as “reference” documents that can assist in understanding the parties’ intentions and, thus, assisting the Korean court in making a decision that complies with the pre-marital wishes of the parties. Additionally, a divorce may be concluded outside of Korea in a jurisdiction where prenuptial agreements are more effectively enforced.

Prenuptial Agreements in Korea

IPG Legal’s Family Law Team emphatically believes that if you want to assist in more efficiently and predictably dividing assets in divorce and/or via inheritance, it is advisable to have a prenuptial agreement, an estate plan, a will, a living will, and in some cases, a trust. We also advise including all potential issues related to marriage in a long-form prenuptial agreement that considers not only matters related to the division of property but also issues such as inheritance, pensions, the habitual residence of the child, child support, and child-rearing.

If you reside in Korea or have assets there, it is advisable to have a proactive Korean attorney assist with the planning and drafting of your prenuptial agreement – do not merely pull an agreeement of the internet.

Enforceability of Prenuptial Agreements in Korean Courts

Prenuptial agreements, often called “prenups,” are becoming increasingly common in South Korea, particularly as more couples delay marriage, accumulate individual assets, and/or enter into international marriages. However, the legal status and enforceability of prenuptial agreements in Korea differ significantly from those in Western jurisdictions.

Under Korean law, a Korean prenuptial agreement is a legally binding contract between two individuals who intend to marry, outlining the division of property and other matters in the event of divorce or the death of one of the parties. While the term “prenuptial agreement” is commonly used even in Korea, the Korean Civil Act refers to such an agreement as a “marital property agreement” (Article 829).

Korean Prenuptial Agreement Formalities

For a Korean prenuptial agreement to be a valid and enforceable agreement, the agreement must be:

1. In writing;
2. Executed before marriage;
3. Registered;
4. Based on the voluntary consent of the parties; and
5. Both parties must have the legal capacity to enter into the agreement.

It is essential to follow these formalities and also comply with the formalities of your home jurisdiction, any jurisdiction in which you have assets, and any jurisdiction in which you intend to reside. We here at IPG Legal err on the side of utilizing the most formalities, and we have the agreement, in most cases, notarized, witnessed, registered, and have a certified translation of the document.

Scope Limitations on Prenuptial Agreements in Korea

The governing law limits the scope of prenuptial agreements to matters related to property rights and financial arrangements; however, this does not mean that other issues cannot be addressed within prenuptial agreements. Even if not enforceable, on its face, in Korea, if a divorce matter is filed in a Korean court, the prenuptial agreement can be used as a reference document to demonstrate the parties’ wishes prior to marriage.

In many cases, this wish is the key to deciding in favor of the moving party who wishes to enforce the prenuptial agreement. Additionally, in some cases, a prenuptial agreement may be utilized in a divorce proceeding outside Korea, in a jurisdiction where such agreements are enforceable for matters beyond property rights.

Common property rights and financial arrangements noted in prenuptial agreements in Korea include:

• Separation of property acquired before and during the marriage
• Distribution of marital property in case of divorce
• Management of jointly owned assets
• Liability for debts
• Separation of pensions
• Separation of inheritances

International Prenup Agreements Enforceability in Korea

With the rise in international marriages in Korea, it’s not uncommon for a couple to draft a prenuptial agreement in another jurisdiction. However, foreign prenups are not automatically recognized in Korea; thus, it is advisable to discuss the matter with an experienced lawyer in Korea and have the lawyer follow the formalities for registration in Korea. In some cases, we advise multiple prenuptial agreements.

Prenuptial agreements in Korea can be a valuable tool for protecting individual assets, clarifying financial expectations, and reducing conflict in the event of divorce. However, to ensure enforceability, careful attention must be paid to the specific legal requirements under Korean law, the law of your home jurisdiction, and the law of the location of assets.

For both domestic and international couples, early legal advice and proper registration are key. If you’re considering a prenup in Korea or already married and wondering about your options – it is strongly recommended to Schedule a Call with IPG Legal.
