Scenario: Nam, a Vietnamese, and Sofia, an Italian, married in Ho Chi Minh City in 2021 without signing any property paperwork. They have since bought an apartment titled in both names, while Nam wants to invest his pre-marital savings in stocks. They disagree: would the apartment be split equally on divorce, and do investment gains from his separate savings count as joint property? The answer lies in the property regime the law applies automatically when spouses agree on nothing — something most couples ignore until a dispute erupts.
The statutory regime: automatic when there is no agreement
Articles 33 to 36 of the 2014 Law on Marriage and Family build the default regime. Joint property covers assets created by the spouses during the marriage, income from work and business, yields and profits generated by separate property during the marriage, and assets jointly inherited or jointly gifted. Separate property covers what each person owned before marriage, assets separately inherited or gifted during the marriage, and assets serving personal essential needs.
The biggest surprise for most people: yields and profits from separate property arising during the marriage are still joint property, unless the spouses agree otherwise. So the interest on Nam’s separate savings in the example, if earned after the wedding, is joint property by default. On divorce, joint property is in principle divided equally, adjusted for family circumstances, each party’s contributions and fault; separate property stays with its owner and is not divided.
The agreed regime: designing your own rules
Articles 47 and 48 let spouses override the default with a written agreement notarized or certified before marriage registration. The core difference is freedom: spouses may decide for themselves what counts as joint or separate, including items the statutory regime automatically treats as joint — for example, keeping yields from separate property as separate, or fixing a jointly bought apartment’s ownership at a ratio other than 50-50.
The agreed regime is also more flexible for cross-border assets, which the statutory regime does not address in detail. Vietnamese-foreign couples can spell out in the document how to handle real estate abroad, investment accounts or stakes in foreign companies, reducing conflicts of law if a cross-border dispute arises.
The two regimes side by side
As to origin, the statutory regime is imposed by law and applies automatically; the agreed regime is chosen by the spouses and only arises with a valid document. As to form, the statutory regime needs no paperwork at all; the agreed regime requires a notarized or certified document executed before the wedding. As to content, the statutory regime classifies property by the rigid formula of Articles 33–36; the agreed regime lets spouses redraw the joint-separate boundary within the law’s limits. As to effect on third parties, the agreed regime binds a good-faith third party only if they knew or should have known — so presenting the agreement in major transactions is essential self-protection.
Which regime: three deciding questions
- Do either of you hold significant pre-marital assets in one or both countries? The more separate property, the stronger the case for an agreement.
- Do you want yields from separate property to stay separate? The statutory regime defaults them to joint.
- Do you plan investments or business ventures with debt risk? An agreement ring-fences debt liability more clearly.
If the answer is no across the board and both fully trust the law’s equal-split formula, the statutory regime suffices. Otherwise, one session with a lawyer before the wedding costs far less than a multi-year property fight after a divorce.
Frequently asked questions
1. Without signing anything, each keeps what is theirs — right?
Wrong. With no agreement, the statutory regime applies automatically: assets created during the marriage and yields from separate property are joint property — not whoever-earned-it-keeps-it.
2. Does a house bought before marriage become joint property?
No, if proven to have been bought with separate pre-marital funds and never merged into the joint pool by agreement. But rental income from that house during the marriage is joint property under the statutory regime.
3. Can spouses switch from statutory to agreed regime after the wedding?
Not through Articles 47–48, since the document must predate marriage registration. After the wedding, spouses can only divide joint property through a different procedure.
4. Must one spouse help repay the other’s separate debts?
Under the statutory regime, debts meeting the family’s common needs are joint debts; pre-marital personal debts or debts not serving the family stay with the borrower, unless agreed otherwise.
5. Does the property agreement bind a bank in a mortgage?
Yes, if the bank knew or should have known about it. So when taking a large loan, present the property-regime agreement to the bank from the start.
