When a husband or wife dies, most families do not realize that half of the couple's marital property already belongs to the surviving spouse and is not part of the estate to be divided. Dividing that share too, or conversely folding separate property into the estate by mistake, is an error that voids the estate declaration, gets the title-transfer file rejected, and pulls family members into drawn-out disputes.
The home that both spouses built together, now that one has died, must it be divided among all the heirs? How much does the surviving spouse keep, and does that person still receive a further share as an heir? Land registered in the deceased's sole name, is it automatically their separate estate, or can it still be marital property? Answer any of these questions wrongly, and you may divide away someone else's share or forfeit your own. The article below analyzes how Vietnamese law determines what is common property and what is separate property, why the marital property must be separated before the estate is divided, and the concrete steps to get it right from the start.
Why Marital Property Must Be Separated Before Dividing the Estate
The starting point of every inheritance division where the deceased was married is a simple principle that is often overlooked: the estate is not all the property in the deceased's name, but only the share that belongs to them alone.
For a married person, "property held in common with others" is first and foremost the couple's marital property. So before any division among the children or other heirs, the law requires an intermediate step: splitting this marital property in two.
What does this mean for you? Suppose the couple owns a home that is marital property worth VND 4 billion, and the husband dies. First, the home is split in half: VND 2 billion belongs to the surviving wife as her separate property, entirely outside the estate. Only the remaining VND 2 billion, the husband's share, is the estate to be divided. If the family divides the full VND 4 billion among the children, they have unwittingly taken away half of the property that was the wife's all along.
That is not all. The surviving wife not only keeps half of the marital property, but is also a first-rank heir to the husband's estate, on equal footing with the children.
Returning to the example above, if the husband dies without a will and leaves a wife and two children, the VND 2 billion estate is divided into three equal shares: the wife, the first child, and the second child each receive about VND 667 million. In total, the wife receives VND 2 billion (half of the marital property) plus about VND 667 million (the inheritance share), that is, nearly VND 2.67 billion out of the VND 4 billion. Skip the splitting step, and this figure is calculated entirely wrong.
Distinguishing Marital Property from Separate Property
Because only the deceased's share is the estate, the entire dispute usually narrows to one question: which property is common and which is separate? This boundary determines whether the estate is large or small, and how much each person receives. The law determines common property by the time and origin of its formation, not by whose name is on the paperwork.
Under Article 43 of the same law, separate property includes property each person owned before the marriage; property separately inherited or separately given during the marriage; property allocated separately to a spouse; and property serving each person's essential needs. Importantly, property formed from separate property remains separate property, for example money from the sale of a pre-marriage home used to buy another. But here is where many families lose their share: if a person cannot prove that an asset is separate, the law presumes it to be common property.
The practical consequence is clear. Heirs of the deceased who want to establish that an asset was that person's separate property, so as to keep it fully within the estate, must hold documents proving its origin. Conversely, the surviving spouse who wants to prove that an asset is their own, so it is not drawn into the estate divided among others, must do the same. Without evidence, everything reverts to the "common property" presumption and is split in half.
Procedure for Determining and Separating Marital Property When Dividing the Estate
In practice, determining marital property is not an abstract calculation but is tied to the procedure for declaring and dividing the estate at a notarial organization or before the court. The basic procedure comprises the following steps.
- List and classify all property. Compile an inventory of every asset connected to the deceased: real estate, deposits, shares, vehicles, capital contributions; then, for each asset, determine when and from what source it was formed in order to classify it as common property or separate property.
- Split the marital property in half. For the portion that is common property, half is recorded as belonging to the surviving spouse. The other half, together with the deceased's separate property, forms the estate.
- Execute the estate division document. The heirs jointly agree and request notarization of the estate division document; in it, the surviving spouse usually participates in two capacities: as a co-owner reclaiming half of the marital property, and as an heir receiving a share of the estate.
- Public posting and completion of title transfer. The notarial practice organization publicly posts the estate division before notarizing it; the parties then complete the notarization and register the title transfer according to the shares divided.
When notarization is requested, the heirs prepare the estate division document, and the notary is responsible for checking it to ensure the division complies with the Civil Code (Article 59, Law on Notarization 2024). A mandatory step before notarization is public posting, so that anyone who believes they have a right or have been left out can speak up before the estate is fully divided.
If the parties cannot agree on what is common property and what is separate, or if an heir believes the division is wrong, the determination will be resolved by the court. At this stage, the marital property is still separated under the split-in-half principle above, but with an added protective mechanism: if dividing the estate would seriously affect the life of the surviving spouse and the family, that person may request the court to limit the division of the estate (Clause 3 Article 66, Law on Marriage and Family 2014).
Legal Risks and Common Mistakes in Practice
Most inheritance disputes among family members stem not from a lack of affection, but from wrongly determining the marital property at the outset. Below are the mistakes that recur again and again.
Treating all property in the deceased's name as the estate. This is the most common error. A home bought during the marriage but registered only in the husband's name is still marital property; when the husband dies, only half the home is the estate. If the whole family assumes the entire home is the husband's alone and divides all of it, the wife is stripped of half of her own property, and the estate division document may be declared void when she sues.
Folding separate property into the estate by mistake, or omitting common property. A home that the husband's parents gave to him separately, or land he owned before the wedding, is separate property and should go fully into his estate; if it is mistaken for common property and split in half first, the children lose a portion. Conversely, a savings book formed from common income during the marriage but in the wife's name is still common property; overlooking it leaves the husband's estate under-declared.
Believing that "whoever holds the title has full power." Many people believe that property in the surviving spouse's sole name is theirs to dispose of freely, or that property in the deceased's sole name is automatically divided in full. Both are wrong: what decides the matter is whether the property is common or separate, not the name on the paperwork. A surviving spouse who unilaterally sells a marital asset before the estate is divided may render the transaction void, dragging the buyer into the dispute.
Failing to keep documents proving the origin of separate property. As noted, when separate property cannot be proven, the asset is deemed common and split in half. After many years, heirs often no longer hold the purchase contract, gift deed, or cash-flow statements, so even if an asset truly is separate property, it remains hard to protect before the court.
DEDICA's Role in Determining Marital Property and Dividing the Estate
Determining the boundary between common and separate property is work that demands both reading the rules correctly and reconstructing the formation history of each asset. DEDICA helps clients review the couple's entire property base, classify it as common or separate based on time and origin, and gather and standardize documents proving origin, so as to determine the estate correctly before proceeding with the declaration.
When family members have not yet agreed, DEDICA represents them in negotiations so the parties reach a reasonable division and avoid going to court; where litigation is unavoidable, DEDICA lawyers take part in the proceedings to protect the surviving spouse's marital property as well as the client's inheritance rights. DEDICA also accompanies clients in notarizing the estate division document and registering the title transfer, so the outcome is fully recognized by law.
Conclusion
To divide an inheritance correctly when the deceased was married, the procedure has three core steps: (1) list and classify all property as common property and separate property, based on the time and origin of formation rather than the name on the paperwork; (2) split the marital property in half, keeping one half for the surviving spouse; (3) add the other half to the deceased's separate property to arrive at the estate, then divide it by rank of heirs, in which the surviving spouse is also a first-rank heir. The three errors that most often cost families their share or spark disputes are: treating all property in the deceased's name as the estate, folding separate property into common property by mistake (or omitting common property), and failing to keep documents proving origin to rebut the "common property" presumption. Before signing any estate declaration or division document, determine the boundary between common and separate property clearly, and check whether a prenuptial agreement exists.
