Quick answer: The biggest difference is what happens to each owner's interest. Under joint tenancy, HDB states that co-owners hold equal shares and the right of survivorship applies, so a deceased owner's interest passes automatically to the surviving joint owner(s). Under tenancy-in-common, each owner holds a defined share, and that share forms part of the deceased owner's estate and is distributed under a will or the applicable intestacy rules.
Key takeaways
- Joint tenancy is commonly chosen when owners want survivorship and do not need separate legal shares.
- Tenancy-in-common is useful when owners want clearly defined ownership proportions.
- A will does not override the survivorship feature of a joint tenancy for the deceased joint tenant's interest.
- For tenancy-in-common, the deceased owner's share does not automatically pass to the surviving co-owner.
- HDB permits eligible co-owners to change the manner of holding between joint tenancy and tenancy-in-common, subject to its process.
- This is an ownership and estate-planning decision, not merely a form-filling choice.
Joint tenancy: the survivorship structure
HDB's ownership guidance describes joint tenancy as a structure where all flat owners have an equal share and the right of survivorship applies. If one owner dies, that person's interest automatically passes to the remaining joint owner or owners, regardless of a will made by the deceased owner.
For many married couples buying a family home, that simplicity can be attractive. But it can be the wrong structure if the owners intend their respective interests to pass to different beneficiaries.
Tenancy-in-common: separate defined shares
Under tenancy-in-common, each co-owner holds a separate and definite share. The percentages do not have to be equal where the relevant transaction and rules allow different proportions.
HDB states that the right of survivorship does not apply. When a tenant-in-common dies, that owner's share is distributed according to the will, if there is one, or under the applicable intestacy law if there is no will.
A simple example
| Structure | Ownership | If one owner dies |
|---|---|---|
| Joint tenancy | Equal legal shares under HDB's description | Interest passes to surviving joint owner(s) by survivorship. |
| Tenancy-in-common | Defined separate shares, e.g. 70/30 where permitted | Deceased owner's share passes through the estate. |
Which structure is better?
There is no universally better choice. The question is what you want the ownership to achieve.
Joint tenancy may suit:
- spouses who want the surviving spouse to own the home automatically;
- owners who do not need unequal legal shares; and
- households seeking a simpler survivorship outcome.
Tenancy-in-common may suit:
- co-owners contributing in clearly different proportions who want those legal shares recorded;
- siblings or non-spousal co-owners with separate estate plans; or
- owners who want their share to pass under a will rather than automatically to the co-owner.
Can HDB owners change the manner of holding later?
HDB currently allows two or more flat owners to apply to change their manner of holding from joint tenancy to tenancy-in-common, or vice versa. Existing tenants-in-common may also apply to change ownership proportions. HDB describes this as a legal conveyancing process and notes that the shares for tenancy-in-common must add up to one.
A later change can involve legal documentation and, depending on the circumstances, other financial or estate consequences. Do not assume changing the label is cost-free simply because there is no sale to an outsider.
NexDoor's view: choose based on the exit, not only the purchase
Most buyers focus on getting the keys and barely discuss the ownership structure. The better time to think about it is before completion.
Ask:
- If one owner dies, who should receive that person's interest?
- Are your contributions intentionally equal or unequal?
- Do you each have children or beneficiaries from different family circumstances?
- Could one owner later want to sell or transfer a share?
- Does the ownership structure align with your will and wider estate plan?
The correct answer is personal, and for complex families it should be confirmed with a lawyer.
Three ownership situations where the choice becomes clearer
Married couple buying a long-term family home: joint tenancy may be attractive where both spouses want the surviving spouse to take the property interest automatically and there is no intention to ring-fence unequal shares for different beneficiaries.
Siblings buying together: tenancy-in-common may deserve closer consideration where contributions are different or each sibling intends his or her share to pass under a separate estate plan.
Blended family: where one or both owners have children from earlier relationships, the survivorship effect of joint tenancy can materially change the eventual inheritance outcome. This is a situation where legal estate-planning advice is especially important.
Contribution percentage and legal ownership are not the same conversation
Couples sometimes assume that whoever pays more of the downpayment or monthly instalment automatically owns a larger legal share. The manner of holding and registered ownership structure should be considered deliberately. If you want unequal legal shares, the conveyancing documents must reflect the permitted structure rather than relying on an informal family understanding.
Questions to resolve before completion
- If one owner dies first, should the surviving owner receive the property interest automatically?
- Do the owners want equal or defined unequal legal shares?
- Are there children or other beneficiaries whose inheritance should be protected?
- Will one owner contribute materially more cash or CPF?
- Could the owners later need to change the manner of holding?
- Does the ownership choice align with existing wills and insurance arrangements?
Why changing later is not always as simple as changing a form
HDB provides processes for eligible flat owners to change the manner of holding or ownership proportions, but the exercise is a legal conveyancing transaction. For private property, a change of shares can also create stamp-duty, financing and CPF consequences depending on how it is carried out. The cheapest time to think through the ownership objective is usually before the original purchase completes.
FAQ
If we are joint tenants, can my will give my share to my child?
The right of survivorship applies to the joint-tenancy interest, so the deceased owner's interest passes to the surviving joint owner(s) rather than under the will.
Does tenancy-in-common mean one owner can only use part of the home?
No. HDB states that all co-owners are entitled to use the whole flat regardless of their percentage share.
Should unmarried couples automatically choose tenancy-in-common?
Not automatically. The right structure depends on contributions, intended inheritance and legal advice.
Buying with someone else?
NexDoor can help you identify the ownership questions to resolve before you buy. For estate planning and the legal effect of the chosen structure, obtain advice from a conveyancing or estate-planning lawyer.
