YAP MEI LEE & ORS v LAU MONG FIU & ORS [2024] CLJU 870
Factual Background
The plaintiffs, as the deceased investor’s executrix and beneficiaries, sued two remisiers and CGS-CIMB, alleging negligence, breach of contractual and fiduciary duties arising from post-death dealings with the deceased’s margin financing and share trading accounts, which resulted in forced sales and alleged investment losses.

Summary of the Findings and Principles
The High Court dismissed the Plaintiffs’ claims after finding that they had failed to establish any breach of contractual, fiduciary or common law duties on the part of the Defendants. The Court’s central finding was that the contractual documents governing the deceased’s share trading and margin financing accounts remained binding upon his estate after his death. Unless a contract is invalidated by a recognised vitiating factor or is one of a personal nature that terminates upon death, the estate assumes both the rights and obligations of the deceased. Consequently, the Plaintiffs could not rely on the contractual documents to assert rights against the Defendants while simultaneously denying that the estate remained bound by the same contractual terms.
A key issue considered by the Court was to whom the Defendants owed their duties after the deceased’s death and when those duties arose. The Court held that any duties owed by the Defendants were owed only to the deceased’s legally recognised personal representative, namely the executor or administrator appointed by the Court. Such authority only arises upon the issuance and production of a valid Grant of Probate or Letter of Administration. The broker was therefore entitled to insist on satisfactory documentary proof before recognising or acting upon instructions concerning the deceased’s trading accounts. A death certificate alone, or a defective Grant of Probate containing material errors, was insufficient to confer legal authority. The Court also found that although the first defendant had delayed forwarding the amended Grant of Probate to CGS-CIMB, the Plaintiffs failed to establish that this delay gave rise to the losses claimed.
The Court further rejected the Plaintiffs’ contention that the Defendants owed broad implied contractual, advisory or fiduciary duties beyond those expressly contained in the contractual documents. It reaffirmed the principle that where parties have expressly agreed on their respective rights and obligations, the Court will not imply terms or impose common law duties that contradict those express contractual provisions. The Court therefore declined to impose additional duties requiring the remisiers or CGS-CIMB to advise the Plaintiffs on investment strategies, protect the value of the portfolio, or supervise the trading accounts beyond their contractual responsibilities.
The Court also considered the Plaintiffs’ allegations concerning the post-death trading activities, the issuance of margin calls, and the eventual forced sale of the securities. It held that the margin facility was governed by clear contractual provisions which entitled CGS-CIMB to issue margin calls, terminate the facility upon default, and liquidate the pledged securities where the estate failed to regularise the margin position. The evidence showed that CGS-CIMB repeatedly afforded the Plaintiffs opportunities to settle the outstanding indebtedness, including allowing instalment payments and accommodating requests not to immediately liquidate the collateral. When those opportunities were not taken, CGS-CIMB was contractually entitled to exercise its rights of liquidation. The Court therefore found that the forced sale was carried out pursuant to the contractual framework rather than as a consequence of any wrongful conduct.
Finally, the Court found that the Plaintiffs had failed to prove that any alleged acts or omissions by the Defendants caused the losses complained of. Having failed to establish any actionable breach of duty or causation, all claims against the Defendants were dismissed with costs.
