Handwritten house-sale promise secures S$300,000 each for brothers left out of will

David Chan Yip Tong needed to sign before a S$5 million sale of the semi-detached house he owned with his brother could proceed. He refused until Franklin Chan Yip Tong agreed in writing to set aside S$600,000 for two other brothers who had been left out of their mother’s will. Both signed a handwritten note on 11 September 2021; David then signed the Option to Purchase.

That exchange has now proved decisive. On 19 October 2026, Justice Christopher Tan held that the handwritten agreement was binding: George Chan Yip Tong and Jack Chan Yip Tong were to receive S$300,000 each. Their entitlement came from the later bargain between the house’s co-owners—not from a court rewriting their mother’s will.

A family promise before there was a buyer

The dispute began with an uneven distribution of the family’s inheritance. The brothers’ mother died on 21 December 2012. Her will named David, Franklin, their late brother Peter’s daughter Dione, and George’s daughter Joanne as beneficiaries. George and Jack themselves were not named.

David and Franklin received equal shares in the semi-detached house on Eng Kong Road. That house was only part of the estate: the will also dealt with a retail unit at Far East Shopping Centre and a Springdale condominium unit at Hindhede Walk. The later S$600,000 dispute concerned money from the house sale, rather than a redistribution of all those assets.

Around June 2018, the brothers’ Mauritius-based uncle, Tam Sook, travelled to Singapore to try to reconcile the family. He proposed that David and Franklin each contribute S$300,000, allowing George and Jack to receive S$300,000 apiece. The brothers agreed in principle, but that oral arrangement was never carried out.

The proposal therefore preceded the eventual house-sale agreement by more than three years. It supplied the background to David’s demand when Franklin later arrived with a buyer’s paperwork.

The signature that unlocked the sale

On 11 September 2021, Franklin brought David an Option to Purchase for the Eng Kong Road house at S$5 million. David would not sign unless Franklin agreed to the payment for George and Jack. After an argument, the two co-owners signed the handwritten note, followed by David’s signature on the sale document.

The sequence mattered. David was not simply asking Franklin to repeat a family promise after the transaction was settled. His consent to sell was still needed, and he made that consent conditional on the written agreement. That connection became central to the court’s reasoning.

The amount was substantial but specific. S$600,000 represented 12% of the S$5 million sale price, with each intended recipient’s S$300,000 equivalent to 6%. Those are calculations against the gross sale price, not estimates of either owner’s net proceeds after costs.

The sale completed on 8 April 2022. To allow completion while the agreement remained disputed, David and Franklin placed S$600,000 in a joint Standard Chartered Bank account. The house could change hands without first settling who was entitled to that reserved money.

Why the handwritten note held up

Franklin challenged the note on two grounds: that it lacked “consideration”, and that he had signed under economic duress. Both arguments failed.

Consideration means something of legal value given in exchange for a contractual promise. Here, the court found that David’s agreement to sell provided that value. As a co-owner, he could withhold his consent; agreeing to sign the Option to Purchase was therefore a meaningful part of the bargain.

In everyday terms, the exchange was straightforward: Franklin agreed to the payment arrangement, while David agreed to a sale he otherwise would not approve. The court treated those linked commitments as an enforceable contract, rather than an unsupported promise to make a gift.

Franklin’s economic-duress defence also did not succeed. Justice Tan rejected his argument that the circumstances in which he signed invalidated the agreement. The finding was that the note’s terms had to be honoured—not that Franklin’s allegation of duress was established.

An inheritance dispute, but a separate entitlement

For George and Jack, the important distinction is the source of their payment. They remained outside the beneficiaries named in their mother’s will. The S$300,000 each arose instead from an agreement signed by David and Franklin years after her death, when the inherited house was being sold.

The judgment addresses a wider collection of family, rental, estate-account and defamation disputes; this ruling on the handwritten note should not be read as resolving every disagreement between the brothers. The published judgment also states that it remains subject to final editorial corrections or redaction.

For this part of the family dispute, however, the consequence is clear: the S$600,000 reserved when the sale completed must be distributed under the agreement. An uncle’s proposed reconciliation had remained unfulfilled, but the written bargain made at the point of sale was binding.
