When a Vietnamese ancestor altar changes: a first altar, moving house, mourning and replacing old items
Short answer: a Vietnamese ancestor altar is not fixed for life. It changes as the family changes: a new altar when a son or daughter sets up their own home, a careful move when the family relocates, a separate altar when someone dies, a merging ceremony after the mourning period, and replacement of worn or broken items. Each of these moments has a broad custom behind it, but the details vary by region and by family line. The safest approach is to ask the elders, act sincerely and keep fire and smoke under control.
Other articles on this site explain what sits on an altar, where it goes and the monthly rhythm of incense. This one covers the moments when the altar has to change. Those are the moments families find most confusing, especially young couples, people living far from their home province, and foreigners who have married into a Vietnamese family and suddenly find themselves helping to carry an incense bowl across town.
Why an altar has a life of its own
For most Vietnamese families, the bàn thờ gia tiên (ancestor altar) is where the living keep their bond with those who have died. When the family changes, the altar changes too. Someone who has just passed away needs to be honoured. Children move to another city. A new house needs to "invite" the ancestors in. Each change is marked with a small ritual, so that everyone involved feels the transition has been done properly, from beginning to end.
It is worth saying clearly from the start: almost everything below is custom and belief, not rule. There is no single national standard. A family line in Nghệ An, a household in Saigon and a devout Buddhist family may each do things differently and all be right by their own tradition.
Setting up an altar for the first time
The common pattern is that the eldest son keeps the main altar in the family home. When younger children move out, families handle it in different ways. Some set up a "remote" altar, called thờ vọng, to honour parents and grandparents from afar. Some keep only a Buddhist or household-deity altar. Some set up nothing until their own parents pass away. These days many families are flexible, particularly when the children live in a city far from home. Before setting one up, ask your parents or the head of the family line what your family does, so you do not end up putting up an altar and then having to take it down.
What you need
A minimal set usually includes an incense bowl, lamps or candles, a flower vase, a fruit plate, a small cup of water and, if you are honouring a parent who has died, their portrait. You do not need to buy everything at once. Choose an incense bowl with sound glaze and no cracks, sized to fit the altar shelf. If you use electric lamps, pick ones with a recognised electrical safety mark. Our piece on what is on a Vietnamese ancestor altar goes through each item.
Installing the incense bowl
A new incense bowl is usually prepared before it goes on the altar. It is cleaned, filled with clean ash or sand, and in some regions a few small symbolic items are placed inside according to local custom. Many families ask an experienced older relative or the local pagoda to do this. Then the family picks a day, prepares a simple offering and invites the ancestors to the new altar. The most important part is that the bowl is set level and secure, and is not casually moved after that.
Moving an altar to a new home
Moving house is when altars tend to be treated most carelessly: the incense bowl thrown into a box with the saucepans, the portrait squeezed between duvets. Older relatives notice this. The common practice looks like this:
- Light incense at the old house and ask permission. Tell the ancestors the family is moving. If your family checks dates, pick a suitable day and hour.
- Wrap the incense bowl and portraits separately. Use a clean cloth, put them in their own box and have a family member carry them, not the removal truck.
- Do not empty the ash. Keep the bowl as it is. If you are worried about spills, cover the top with red paper or a clean cloth.
- Altar first, furniture second. At the new home, the altar is installed first and the incense bowl placed on it before other things are unpacked.
- Hold the move-in ritual. We cover that in moving house in Vietnam.
Families who rent and move often can use a compact wall-mounted altar that is easy to take down and put up, and keep the same set of altar items through every move. For elders, continuity of the objects matters more than the size of the altar.
When someone in the family dies
This is the biggest change, and the time when the family has the least energy for details. Most of the funeral and mourning rituals are guided by senior relatives, the pagoda or the funeral organiser. This section only sketches the broad milestones, so that family members, especially those who did not grow up in Vietnamese culture, understand what is happening around them.
A separate altar for the recently deceased
In many places, a person who has just died is honoured at a separate small altar, set lower than or beside the main ancestor altar. It holds their portrait, their own incense bowl and a lamp, and for a period the family offers a bowl of rice and food each day. The milestones most families observe are the 49th day, the 100th day, the first death anniversary and the end-of-mourning anniversary, often two or three years after the death. The names and the details of each milestone vary by region and by the family's religion.
Joining the main altar
After the mourning period, often after that final anniversary, many families hold a ceremony to move the deceased onto the main altar with the other ancestors. The portrait goes up to the main altar, and some ash or incense stubs from the separate bowl are added to the shared one; the old bowl is then burned, buried respectfully or taken to a pagoda. The timing and the method vary widely, and some families do it earlier or keep the separate altar longer. This is a question for the senior relatives, not for an article.
Daily incense and smoke
In the first weeks, families often keep incense burning almost constantly and offer food every day. In a tube house or a sealed apartment, smoke builds up fast. Open a window, use low-smoke incense, keep someone near any burning candles and keep flames away from curtains, mourning cloths and paper flowers. When the whole family leaves for the burial, put candles out and leave only electric lamps on.
Daughters, daughters-in-law and sons-in-law
By old custom, a daughter who marries joins her husband's family's worship. In practice things are now much more varied. Families with only daughters often have a daughter who continues honouring her own parents. Some couples keep two incense bowls, one for each side. Some share one altar for both. None of these is "wrong" if both families agree. What is worth avoiding is deciding alone and leaving one side of the family offended.
For foreign spouses, or spouses of another faith, most Vietnamese families do not expect full participation in every ritual. Many Catholic families in Vietnam keep portraits of their ancestors and light candles in remembrance in their own way. A simple gesture, such as standing quietly before the altar, bowing your head, or helping to set out the meal on a death anniversary, is warmly received.
Old, cracked or faded altar items
Altar items wear out over the years: an incense bowl cracks, a portrait fades, a vase chips, a painted statue peels. Folk custom says broken items should not stay on the altar, and should not go in the household rubbish. Common ways to handle them:
- A cracked incense bowl: light incense to ask permission, transfer the ash to a new bowl, and take the old one to a pagoda or break it up and bury it somewhere clean. Some people release old ceramics into a river; if you do, only ceramic, never plastic bags or plastic items.
- A faded portrait: print a fresh copy; the old one can be burned with votive paper or kept in the family album.
- An overfull incense bowl: trim the stubs at the end of the lunar year, as described in our piece on cleaning the altar before Tết.
- A chipped Buddha or deity statue: many people take it to a pagoda to be left there respectfully, never at a rubbish tip or the foot of a roadside tree.

A worked example: a city couple, a father who died in the countryside
A younger son lives in the city with his wife, who is from abroad. His father dies in their home province; the funeral and the main altar are handled by his eldest brother. Afterwards, he wants somewhere to light incense for his father in their apartment.
He asks his brother and his mother first. His mother agrees to a remote altar and tells him to keep it modest. He buys a small wall-mounted altar, an incense bowl, a reprint of his father's portrait and electric altar lamps. His wife helps pick the spot: a solid wall in the living room, not facing the door, near a window so smoke can clear. On the first death anniversary, the couple travel home for the main ceremony, then light incense at their own altar that evening. When the main altar later holds the merging ceremony, he checks with his mother again and keeps his remote altar as it is, only changing the words of his prayer. None of the steps is complicated. What matters most is that everyone was asked.
Common mistakes
- Setting up or moving an altar without asking the elders. A small decision can turn into a family dispute.
- Packing the incense bowl like any other object. Older relatives notice; wrapping it separately and carrying it by hand shows respect.
- Burning incense non-stop in a closed room during mourning. Hard on elderly people and children; open a window and use low-smoke incense.
- Believing "a wrongly placed incense bowl will bring disaster". This is fear selling a service. Get a second opinion before paying anyone.
- Throwing broken altar items in the bin. It upsets neighbours, and broken porcelain can cut waste collectors.
When to bring in a professional
For ritual questions, ask senior relatives, the local pagoda or a well-regarded ritual officiant. Be wary of anyone who charges a lot, rushes you, or tells you not to mention it to others; those are signs to slow down. For installation, a heavy wall altar in an apartment is worth checking with an engineer or the building management, and altar lamps and sockets are a job for an electrician. Legal questions about inheriting a house that holds the family altar belong with a lawyer. And if someone at home is grieving for a long time, cannot sleep or stops eating after a death, encourage them to see a doctor or a counsellor. Looking after the altar does not replace looking after the living.
If your family needs to replace an old incense bowl or put together a set for a new altar, the Vietnamese shop Vật Phẩm Phong Thuỷ, which delivers within Vietnam, lists a range of incense bowls where you can compare sizes against your altar shelf before buying.
