The Two Co-Ownership Structures
When two or more people buy a property together in Singapore, they must choose between two legal co-ownership structures: joint tenancy or tenancy-in-common. The choice affects what happens to the property on death, whether shares can be sold or mortgaged independently, how ABSD is calculated on future purchases, and how CPF monies are refunded on sale.
CEA agents are not legal advisers and should not tell clients which structure to choose — that is the role of the conveyancing solicitor. However, agents who can explain the practical implications of each structure clearly will be better trusted advisers and will avoid transactions that fall through because buyers made uninformed structural decisions at the outset.
Key Differences at a Glance
| Feature | Joint Tenancy | Tenancy-in-Common |
|---|---|---|
| Shares defined? | No defined shares — co-owners hold the whole property jointly | Yes — each owner holds a defined percentage (e.g. 50/50, 99/1, 70/30) |
| On death of one owner | Surviving owner automatically inherits the deceased's interest (right of survivorship); overrides will and intestacy rules | Deceased's share passes under their will or intestacy rules — does not automatically go to the co-owner |
| Can one party sell their share? | No — cannot sell a portion without converting to tenancy-in-common first (by severance) | Yes — each co-owner can sell, mortgage, or gift their defined share independently (subject to any co-ownership agreement) |
| ABSD property count impact | Both owners are deemed to own the property; each is counted as owning one property for ABSD purposes | Same as joint tenancy — both co-owners are counted as owning one property regardless of share percentage |
| CPF usage | Each co-owner can use their own CPF OA up to their withdrawal limit; CPF refund on sale is per-person based on actual withdrawal | Same CPF rules apply; each owner's CPF refund is based on their actual CPF contribution and accrued interest |
| Typical use case | Married couples who want automatic survivorship and simpler estate planning | Unmarried couples, family members buying together, investment co-buyers, decoupling strategy |
Joint Tenancy: How It Works
In a joint tenancy, all co-owners hold the entire property together as a single unit — there are no separate shares. The defining feature is the right of survivorship: when one joint tenant dies, their interest passes automatically to the surviving joint tenant(s), regardless of what the will says. This is why joint tenancy is common for married couples — it ensures the surviving spouse owns the property outright without probate delay.
A joint tenancy can be converted to a tenancy-in-common at any time through a process called severance. Severance requires a formal written notice and registration at SLA and converts the joint tenancy into equal shares (50/50 for two owners) unless otherwise agreed. The conversion has no stamp duty implications. Decoupling — where one co-owner transfers their share to the other to free up property count for a new purchase — requires first converting to tenancy-in-common if the property is held as joint tenants.
Tenancy-in-Common: How It Works
In a tenancy-in-common, each co-owner holds a defined, divisible share in the property. The shares are recorded on the title and can be unequal (e.g., one party holds 99% and the other 1%). There is no right of survivorship — each co-owner's share is a separately transmissible asset that passes under their will or intestacy rules.
Common scenarios where tenancy-in-common is chosen:
- Unequal financial contributions: One buyer contributes significantly more (e.g., larger CPF top-up or cash down payment) and wants their share to reflect this in their estate
- Decoupling preparation: Couples who anticipate decoupling in future choose tenancy-in-common (often 99/1) so that one party can transfer their share without converting the tenure first
- Investment co-purchase: Investors who want to protect their individual interest and ensure it can be willed to their own family
- Parent-child co-purchase: Where the child is added as a co-owner to assist with TDSR but the parent wants to retain the beneficial interest
ABSD Implications of Co-Ownership
For ABSD purposes, both joint tenancy and tenancy-in-common result in each co-owner being counted as owning the property — even if one co-owner holds only a 1% share. This is a critical point for upgrade planning: a spouse holding a 1% share in a tenancy-in-common is counted as owning one property, and will pay ABSD at the second-property rate on any future purchase unless they first dispose of their share.
| Scenario | ABSD on Next Purchase | Strategy |
|---|---|---|
| SC couple owns one property jointly (joint tenancy); wants to buy a second property together | 20% ABSD (second property for both) | Sell first property first (no ABSD on replacement); or decouple so one spouse holds the first property alone while the other purchases the second (0% ABSD for the unencumbered spouse) |
| SC couple owns one property as tenants-in-common (99/1); wants to decouple so 1% holder buys another property | 0% ABSD for the 1% holder after decoupling (first purchase for that person) | 1% holder transfers their 1% share to the other spouse; BSD payable on the transfer value (1% of property value, not purchase price); 1% holder then buys new property at 0% ABSD |
| SC and SPR buying jointly; SC's first property, SPR's first property | 5% ABSD (joint purchase assessed at higher applicable rate; SPR first property rate applies) | Consider purchasing in SC's name only (0% ABSD) if TDSR permits on single income; SPR co-ownership triggers 5% ABSD |
Severance: Converting Joint Tenancy to Tenancy-in-Common
Severance converts a joint tenancy to a tenancy-in-common. Either co-owner can sever the joint tenancy unilaterally — there is no requirement for the other party's consent, although the other party must be notified. After severance, each party holds an equal share (50/50 for two co-owners) as tenants-in-common. The shares can then be transferred between the parties to create unequal holdings.
Severance is relevant to decoupling strategies. A couple holding a property as joint tenants who wish to decouple must first sever the joint tenancy to create defined shares before one party can transfer their share to the other.
Severance alone attracts no stamp duty. However, the subsequent transfer of a share from one co-owner to the other is a dutiable instrument — BSD is payable on the higher of the consideration paid or the market value of the share transferred.
HDB Flats: Co-Ownership Rules
HDB flats have specific co-ownership rules that differ from private property:
- All owners of an HDB flat must be listed as essential occupiers or owners under the same eligible household nucleus
- HDB resale flats can be held as joint tenants or tenants-in-common; BTO flats are typically held as joint tenants by default
- Decoupling is not permitted for HDB flats — one owner cannot transfer their share to the other without HDB approval, and HDB generally does not approve such transfers except under specific circumstances (divorce, death, financial hardship)
- HDB co-owners who wish to add or remove co-owners must apply to HDB directly; consent of the existing mortgagee (HDB or bank) is also required
Frequently Asked Questions
Q: If a property is held as joint tenancy and one owner dies, does the surviving owner pay ABSD on the inherited share?
A: No. The transfer of a deceased joint tenant's interest to the surviving joint tenant by right of survivorship is not a purchase — it is a statutory transmission. No stamp duty (including ABSD) is payable on the transmission. However, the surviving owner now holds the property alone and their property count remains at one (for that property). Any future property purchase would be assessed at the relevant ABSD rate for their updated ownership profile.
Q: Can tenants-in-common with unequal shares both use their CPF for the same property?
A: Yes. CPF usage is not limited by share percentage — each co-owner can use their own CPF OA to service the mortgage or fund the down payment, subject to their individual CPF withdrawal limits and the property's Valuation Limit. The CPF withdrawal limit is calculated based on the property's lower of purchase price or valuation, not the individual's ownership share.
Q: A buyer wants to hold 99% and add their parent as 1% holder. Will this affect the parent's ABSD on their next property?
A: Yes. The parent holding even 1% as a tenant-in-common is counted as owning one residential property for ABSD purposes. If the parent later purchases another property, they will pay ABSD at the second-property rate. Before proceeding with this structure, ensure both the buyer and the parent understand the ABSD implications for the parent's future purchases.
Q: Should agents recommend joint tenancy or tenancy-in-common to their clients?
A: No. The choice of co-ownership structure has legal, tax, and estate planning implications that vary significantly by each buyer's circumstances. CEA agents must not give legal advice. The appropriate course is to explain the practical differences in factual terms, note that the choice should be discussed with their conveyancing solicitor, and refer clients accordingly. Agents who recommend a specific structure and it results in adverse consequences may face CEA disciplinary action for providing advice outside their competence.
