The recent decision of the Court of Appeal of Singapore in WMLM v NSRJ [2026] SGCA 27 is one of the most significant property law judgments concerning 99:1 ownership structures, resulting trusts, and beneficial ownership of residential property.

The judgment provides important guidance for purchasers who adopt unequal ownership structures, particularly unmarried couples and investors contemplating future “decoupling” arrangements to facilitate subsequent property acquisitions.

The dispute concerned a condominium at Hillcrest Arcadia purchased for S$1.865 million by an unmarried couple registered as tenants-in-common in a 99:1 ratio, notwithstanding that their financial contributions differed substantially from their registered ownership interests.

The male partner contributed approximately S$359,949 towards the acquisition.
The female partner contributed approximately S$159,678.
The balance was financed by a bank loan.

Following the breakdown of their relationship, the Court was required to determine whether the registered ownership reflected the parties’ true beneficial interests.

In a landmark decision, the Court of Appeal overturned the High Court’s ruling and held that the agreed 99:1 ownership structure represented the parties’ intended beneficial ownership. The Court also examined the legal implications of ownership arrangements associated with the avoidance of Additional Buyer’s Stamp Duty (ABSD).

Three key lessons emerge from the Court of Appeal’s decision:

legal ownership and beneficial ownership are not always identical;
the parties’ intentions at the time of acquisition are critical; and
ownership structures adopted to facilitate the evasion of stamp duty or ABSD may be tainted by illegality, potentially rendering trust claims arising from those arrangements unenforceable.

The Dispute

The male partner contended that, despite holding only a 1% registered legal interest, he possessed a substantially larger beneficial interest because he had contributed significantly more towards the purchase price. He therefore sought a declaration that a resulting trust arose in his favour.

The female partner argued that the registered 99:1 ownership ratio accurately reflected both the legal and beneficial ownership of the property. She maintained that the male partner had knowingly agreed to confer the larger share upon her.

The dispute raised three fundamental legal questions:

Did a resulting trust arise because of the male partner’s greater financial contribution?
Did the parties intend the registered 99:1 ratio to represent their true beneficial interests?
What effect did the parties’ intention to facilitate future property acquisitions without incurring ABSD have on the resulting trust claim?

The High Court’s Decision

The High Court found in favour of the male partner.

Having regard to the parties’ respective financial contributions, the High Court concluded that the male partner held a significantly larger beneficial interest than his registered 1% legal share.

The Judge held that the female partner held part of her registered 99% interest on resulting trust and determined that the male partner was beneficially entitled to approximately 54.22% of the property.

The female partner subsequently appealed.

The Court of Appeal’s Decision

The Appeal Was Allowed

The Court of Appeal reversed the High Court’s decision.

The Court held that the evidence demonstrated that the parties intended the registered 99:1 ownership ratio to reflect their beneficial ownership, and not merely the legal title.

Central to the Court’s reasoning was its analysis of the parties’ intentions at the time the property was acquired. The Court concluded that the parties had consciously adopted the ownership structure and intended the beneficial interests to correspond with the registered legal shares.

Accordingly, no resulting trust arose in favour of the male partner.

The Court’s Analysis of ABSD-Related Arrangements

The Court also considered evidence that the 99:1 structure had been adopted with a view to enabling the male partner to later transfer his 1% interest, acquire another residential property without incurring ABSD.

Although this issue was not determinative of the appeal, the Court observed that such a purpose tainted the resulting trust claim subsequently advanced by the male partner.

The judgment provides valuable guidance on how under-stamping and tax evasion may arise where a trust exists over property held under a 99:1 ownership arrangement.

Under-Stamping and Tax Evasion: Two Distinct Scenarios

Scenario 1 — Transfer of the Entire Beneficial Interest While Declaring Only a 1% Transfer

Where the parties’ beneficial interests differ from their registered legal ownership:

X transfers his entire beneficial interest to Y.
However, only the transfer of the 1% registered legal share is declared for stamp duty purposes.
Stamp duty is therefore assessed only on the 1% legal interest rather than the entire beneficial interest transferred.

The Court explained that this gives rise to:

Under-stamping, because insufficient stamp duty is paid; and
Tax evasion, because there is a knowing misrepresentation of the extent of the transfer in order to reduce stamp duty liability.

Once the beneficial interest has been completely transferred, X no longer retains any interest in the first property and may subsequently purchase another residential property without further ABSD consequences.

Scenario 2 — Transfer of Only the 1% Legal Interest While Retaining a Beneficial Interest

Alternatively:

X transfers only the 1% legal interest.
Stamp duty is correctly paid on that transfer.
X nevertheless retains a beneficial interest in the first property.

In this situation:

There is no under-stamping at the point of transfer because the correct duty has been paid on the legal interest conveyed.

However, complications arise when X later acquires another residential property.

If X:

incorrectly claims to hold no remaining interest in the first property, ABSD remains payable;
genuinely does not realise that a beneficial interest has been retained, the failure to pay ABSD constitutes under-stamping; or
knowingly conceals the retained beneficial interest to avoid ABSD, the conduct amounts to tax evasion, as there is deliberate intent to evade stamp duty.

Key Distinction

The Court emphasised the distinction between the two concepts:

Under-stamping

Payment of less stamp duty than is legally payable.

Tax evasion

Under-payment accompanied by intentional concealment or misrepresentation designed to avoid stamp duty or ABSD.

Knowledge and dishonest intention distinguish tax evasion from mere under-stamping.

Practical Lessons for Property Purchasers

The Court of Appeal’s decision serves as an important reminder that disputes concerning property ownership are ultimately resolved by reference to:

the parties’ true intentions at the time of purchase;
the legal structure they deliberately adopted; and
the contemporaneous evidence supporting those intentions.

Purchasers should therefore:

ensure their choice of registered ownership, for instance joint tenancy or tenants in common, accurately reflects the intended beneficial interests of all co-owners;
avoid informal understandings concerning beneficial ownership;
document ownership arrangements carefully;
obtain legal advice before adopting 99:1 or other ownership structures; and
recognise that tax-avoidance arrangements will taint the transaction and may carry significant legal consequences.

The Changing Landscape for Trust-Based Property Ownership

The judgment also comes against a significantly changed regulatory backdrop.

In recent years, purchasers seeking flexibility in future property acquisitions have explored ownership structures involving:

99:1 ownership arrangements;
declarations of trust; and
trust-based acquisitions.

However, the stamp duty regime has evolved considerably.

Under the current framework, the acquisition of residential property by a trustee generally attracts ABSD (Trust) at 65% of the higher of the purchase price or the market value of the property.

The duty is payable upfront upon acquisition by the trustee, subject to any applicable remission and satisfaction of the relevant statutory conditions.

Although the availability of remission depends on the particular facts, purchasers should appreciate that trust structures are now subject to substantially greater stamp duty scrutiny than in previous years.

From a practical perspective, a purchaser acquiring a S$2 million residential property through a trust may incur an upfront payment of 65% ABSD (Trust) liability of S$1.3 million before any remission is considered. This materially alters the commercial attractiveness of many trust-based ownership structures.

Conclusion

The Court of Appeal’s decision in WMLM v NSRJ [2026] SGCA 27 reinforces that the legal effectiveness of a 99:1 ownership arrangement depends not on the parties’ subsequent assertions, but on their objectively ascertainable intentions at the time of acquisition.

The judgment also underscores the increasingly rigorous scrutiny applied by the courts and revenue authorities in 99:1 ownership arrangement.
