Taiwan marital property division with an American spouse

The main Taiwan claim for dividing what a couple built up during a marriage is the remaining property distribution claim in Civil Code Article 1030-1. The spouse who accumulated less can ask the other for half of the difference. It is a claim for money, not a share in particular assets, so a Taiwan court does not itself move a US brokerage account, a 401(k) or a house in the United States from one name to the other. Whether Taiwan law governs your property at all usually turns on where the two of you were domiciled, and a Taiwan judgment generally collects only from assets in Taiwan.

The divorce itself is covered in the divorce lawsuit Q&A, release clauses in divorcing by agreement, and a US decree in getting it onto Taiwan's household register.

Which country's law decides the property

Taiwan's Act Governing the Choice of Law in Civil Matters Involving Foreign Elements, called the Choice of Law Act in this column, handles marital property in Article 48. If the spouses have agreed in writing to apply the national law or the domicile law of one of them, that agreement governs. Without one, the court looks for a law you share: first a common national law, then a common domicile, and if neither exists, the law of the place most closely tied to the marriage. Divorce has its own rule in Article 50, so the divorce and the property can in principle fall under different laws.

Most American and Taiwanese couples have no common nationality, so the common domicile carries the analysis. If one of you holds both nationalities, Article 2 has the court pick the nationality with the closest connection, so a shared-nationality argument is possible but not automatic. A couple who lived together in Taipei will usually be under Taiwan law. In Taiwan High Court Case 111-Jia-Shang-239 (February 15, 2024), a surviving spouse who was a US national challenged gifts that the deceased spouse had made to some of the heirs, and the court stated in one sentence that Article 48(2) pointed to Taiwan law. The marriage there ended by death, not divorce, and the High Court sent the case back to the Shilin District Court on procedural grounds tied to a third party's intervening claim that certain company investments registered under the deceased spouse's name were really theirs. It decided nothing about the merits. It does show an American spouse bringing this kind of claim in a Taiwan court, and the court applying Taiwan law.

A couple who lived together in the United States are in a different position. A common domicile in California or Texas could point to that state's rules. California and Texas use community property and most other states use an equitable-distribution standard, so the rules differ from Taiwan's formula and from each other. Three cautions follow. Article 48 does not say when the domicile is measured, and no official source or judgment reviewed for this column settles it for a couple who moved from one country to the other, so Taiwan counsel should check your dates. If the court is sent to foreign law, Code of Civil Procedure Article 283 puts the burden of proving that law on the parties, although the court may investigate on its own. And Article 8 lets a Taiwan court refuse a foreign rule whose result offends Taiwan's public order or good morals.

Article 48(3) also steps aside for real property where the law of the place where it sits has special rules, so a house can be governed differently from the rest. A prenuptial or postnuptial agreement is the usual way to choose a law, but it must be in writing and choose the national or domicile law of one of you. Whether a particular clause in a US agreement meets that test depends on its wording and on where each of you lived.

What the claim is

When the statutory property regime ends, Article 1030-1 totals each spouse's existing property acquired after the marriage, minus debts incurred during it. If the totals differ, the difference is split equally. Property one spouse inherited or received as a gift is left out, and so is compensation for emotional harm. The statutory regime is the default in Taiwan under Article 1005, applying unless the spouses made a marital property contract.

A hypothetical, only to show the arithmetic: if one spouse's net post-marriage property comes to the equivalent of US$600,000 and the other's to US$200,000, the difference is US$400,000. The spouse with less could claim half, US$200,000, which would leave each at US$400,000. Property from before the marriage is outside the calculation, though what counts as premarital is a matter of proof. Under Article 1017, property you cannot show to be premarital is presumed to be post-marital, and fruits of premarital property earned during the marriage, such as interest, are treated as post-marital. A 401(k) opened before the wedding shows the difficulty. The balance on the wedding date belongs outside the calculation if you can document it, while contributions during the marriage would ordinarily be post-marital. Whether market gains on the premarital balance count as "fruits" under Article 1017 is a question to put to counsel, not to assume.

The equal split is not mechanical. If equal division would be unfair, the court may adjust or waive the amount, weighing housework and child care, the family's overall contribution, how long the spouses lived together and apart, when the property was acquired, and each spouse's economic position. For a court divorce, Article 1030-4 values the property as of the day the divorce action was filed, not the day of judgment. Those are the dates a US statement or appraisal has to match.

A spouse's property claim can be joined to the divorce action under Family Act Article 41. It is a Class C matter under Article 3, and Article 23 requires court mediation before a Class C case can be decided.

US accounts, a US house and a 401(k)

Nothing in Article 1030-1 limits the calculation to property in Taiwan. The sources reviewed for this column include no published Taiwan judgment that counts a US retirement account or house in the arithmetic, so ask Taiwan counsel how a court is likely to value one before you plan around it.

Collecting is the harder part. A Taiwan enforcement title reaches property in Taiwan, as the column on cross-border child support explains. A Taiwan judgment awarding you a sum does not freeze or transfer a US account. To collect from US assets you would need a US court to give the judgment effect, which varies by state and is a question for a lawyer where the asset is. The mirror-image route is described in enforcing a foreign judgment against assets in Taiwan.

A 401(k) adds a constraint. The US Department of Labor explains that a retirement plan divides a participant's benefit under a qualified domestic relations order, meaning an order made under a US state's domestic relations law, and that the plan administrator, not a court, first decides whether an order qualifies (DOL overview). A Taiwan court order is not made under a US state's law, so it is not obviously one of those. The safe assumption is that a Taiwan judgment gives you a money claim measured partly by the plan's value, not a transfer out of the plan. Whether a plan would act on a Taiwan order is for a US lawyer and the plan administrator.

If a US court has already divided the property in a divorce decree, put the decree in front of Taiwan counsel first. If Taiwan recognizes it, the property question may be settled and a second claim in Taiwan would run into that. If Taiwan does not recognize it, the Taiwan claim stays open. The recognition test is in the column on US decrees linked above.

Proving what the other spouse owns

Civil Code Article 1022 gives each spouse a duty to report on post-marital property to the other. How a court uses that duty once the marriage is in litigation is a question for counsel. Taiwan civil procedure has no US-style pretrial discovery. A party must produce certain categories of document under Code of Civil Procedure Article 344, including documents the party has cited in the case and business account books, and if a party refuses without good reason, Article 345 lets the court treat the other side's account of the document as true after hearing both sides. These provisions operate on the parties. A Taiwan court has no practical way to compel a US bank or plan administrator to produce records.

So the American spouse's best evidence is usually already in their own hands: statements for each US account and plan from the marriage date onward, tax returns and account tax forms, deeds, closing statements and mortgage statements for any house, and records of transfers between accounts. Documents from before the marriage matter as much. A statement from just before the wedding is what lets you keep a premarital balance out of the calculation, and a record of a gift or inheritance does the same for property received that way. Ask the court or counsel which English documents need Chinese translations before paying for them.

Courts have their own tools for Taiwan records. In the Taipei District Court order discussed below, the judge ran a tax-records query on the respondent on the court's own initiative and found property still in the respondent's name. That query covered Taiwan records, not a US account.

The deadlines are short

Article 1030-1 gives the claim two clocks. It ends if the claimant does not exercise it within two years from the time the claimant learns there is a difference in the spouses' remaining property, and in any event once five years have passed since the statutory regime ended. The two years start from knowledge, not from the divorce. How a Taiwan court reads that knowledge on your facts is worth reviewing early, not something to plan around by using the whole period. If a US divorce was granted years ago and nothing was filed in Taiwan, check the five-year limit now. When the statutory regime ended for a divorce granted abroad is itself a point for Taiwan counsel.

Gifts to relatives and other third parties follow separate rules. Under Article 1020-1, a spouse can ask a court to revoke the other spouse's gift of post-marital property during the marriage if it harms the claim, unless it was a fitting gift to meet a moral duty. Article 1020-2 ends that right six months after the spouse learns of the ground, or one year after the act. Separately, Article 1030-3 adds back property a spouse disposed of within the five years before the regime ended to reduce the other's share, and the claim against a third party who received it has its own two-year and five-year limits. The High Court case above was built on this machinery.

If the marriage is still intact but the other spouse is improperly reducing post-marital property in a way that threatens your claim, Article 1010 lets a court, at your request, declare a switch to the separate property regime. That ends the statutory regime, so it matters for the deadlines above.

Freezing assets before judgment

A court can attach property in advance. Code of Civil Procedure Article 522 allows provisional attachment for a money claim to preserve later enforcement. Article 523 requires a risk that enforcement will otherwise be impossible or very difficult, and treats that risk as present where the judgment would have to be enforced abroad. The application can go to the court hearing the main case or to the district court where the asset is located (Article 524), and Family Act Article 51 applies these rules to family lawsuits.

The applicant has to make a showing on both the claim and the reason for attachment (Article 526). If the showing falls short, the creditor can offer security to make up the gap. Even where the showing is complete the court may require security, and for a spouse's remaining property claim, paragraph 4 caps that security at one-tenth of the amount claimed. In a divorce case before the Taichung District Court (Case 113-Jia-Quan-37, order of October 11, 2024), the first order had required NT$270,000 for an attachment of up to NT$800,000. On the applicant's challenge, the court cut the security to NT$80,000, citing paragraph 4.

The showing can also fail. The Taipei District Court (Case 113-Jia-Quan-38, order of December 6, 2024) refused to attach assets for a spouse's remaining property claim. The applicant sought up to NT$15 million while the amount claimed in the pending main case was NT$1 million plus interest. The account records submitted showed withdrawals and fund redemptions in 2018 to 2020, but they did not show where the money had come from, or that it was still gone when the regime ended about four years later, so they did not establish concealment or waste. The court's own tax-records query showed that the respondent still had eight items of property, worth more than NT$10 million. These are two district court orders and bind no other judge, but they show what a Taiwan judge looks for: records current to the reference date, an amount that matches the claim, and a concrete risk of non-collection.

Where attachment is sought before a case is filed, Article 529 lets the debtor ask the court to set a deadline for filing the main case. If the applicant has also asked a court under Article 1010 to switch the couple to the separate property regime, the applicant has ten days from the day that ruling becomes final to sue for the remaining property difference. A Taiwan attachment order reaches only assets in Taiwan. Steps to restrain US assets belong to a US lawyer.

Having a Taiwan lawyer look at it

If you want a Taiwan lawyer to review the choice-of-law question and the deadlines before anything is filed, you can write to Attorney Wei Tseng (曾雋崴) at Hovering International Law Firm at wei@hoveringlaw.com.tw. The Taipei office is at 7F-2, No. 35, Sec. 1, Chengde Rd., Datong Dist., Taipei City 103, Taiwan (103 臺北市大同區承德路一段35號7樓之2). The column on instructing a Taiwan lawyer from abroad explains how an appointment works from overseas. A short summary is enough to start: the marriage date, any separation date, any prenuptial agreement, where each of you was domiciled and when, the US and Taiwan cases so far, and a rough list of accounts and property in each country. This column is general information, and the outcome depends on your documents and the facts.
