Summary
This High Court decision concerns the validity of two powers of attorney (“POAs”) executed by an 87-year-old woman, Mdm Liew Khoon Fong @ Liew Fong (“Mdm Liew”), in favour of her son, Dr Goh Yong Chiang Kelvin (“Kelvin”). The POAs authorised Kelvin to (1) sell Mdm Liew’s residential property at 107 Namly Avenue and direct the sale proceeds to a grandchild, and (2) purchase a condominium unit in joint names of Mdm Liew and the grandchild, with an option for Kelvin to include himself as a joint owner. The dispute arose after Mdm Liew’s daughter, Karen, commenced proceedings under a lasting power of attorney (“LPA”) that came into effect when Mdm Liew developed dementia.
The court’s central tasks were to determine whether Mdm Liew had the mental capacity to execute the POAs and whether Kelvin had exercised undue influence over her to procure their execution. The judgment also addressed the construction and scope of the POAs and the evidential significance of the surrounding circumstances, including medical evidence and the relationship between the parties.
Ultimately, the court held that the POAs were not validly executed because the evidence did not establish that Mdm Liew possessed the requisite mental capacity at the time of execution, and the circumstances also raised concerns consistent with undue influence. The court therefore granted the relief sought by Karen (as donee under the LPA and later as executrix), subject to the procedural history and the effect of earlier interlocutory decisions.
What Were the Facts of This Case?
The parties were siblings and both medical doctors. Karen was the younger child of Mdm Liew. Kelvin was the older child. Their mother owned two major assets during the relevant period: the Namly property (107 Namly Avenue) and a bungalow at Siglap Bank. According to the evidence, their father’s intentions were that, after Mdm Liew’s death, the Namly property would go to Karen and the Siglap Bank property would go to Kelvin. The relationship between Karen and Kelvin became strained, and the dispute later crystallised around how Mdm Liew’s property was dealt with during her lifetime.
In 2014, Mdm Liew executed an LPA in favour of Karen. The LPA provided broad authority over Mdm Liew’s personal welfare and property and affairs, subject to a key restriction: the donee could not sell, transfer, convey, mortgage or charge Mdm Liew’s residential property at 107 Namly Avenue without the approval of the court. The LPA was registered on 16 September 2014. The LPA later came into effect around 15 December 2017 when Mdm Liew developed dementia.
As the dispute developed, Karen sought to prevent the sale of the Namly property. She commenced proceedings and obtained an injunction attempt, but the injunction was refused by Lee Seiu Kin J on 1 March 2018, and the sale proceeded. Claims against the purchaser, Pinnacle Development (Greenmead) Pte. Ltd., were subsequently struck out, and Pinnacle Development ceased to participate in the suit. After Mdm Liew’s death on 10 June 2020, Karen was granted leave to continue the proceedings as executrix of the estate.
In the second half of 2017, Kelvin’s case was that Mdm Liew had become less mobile and needed a wheelchair. He testified that she wanted to sell the Namly property and buy a condominium unit for herself and Kelvin’s family. He further said that she instructed him to see a lawyer so that he could be appointed as attorney to execute her instructions. Acting on this, Kelvin approached a lawyer, Mr Teo, who prepared two irrevocable POAs for Mdm Liew to execute. The first POA authorised Kelvin to sell the Namly property and pay the sale proceeds to Daniel Goh Eng Sheng, Kelvin’s older son and Mdm Liew’s grandchild. The second POA authorised Kelvin to purchase a condominium unit in the joint names of Mdm Liew and Daniel, and included an option for Kelvin to include himself as a joint owner.
What Were the Key Legal Issues?
The court had to decide whether the two POAs were validly executed. This required consideration of Mdm Liew’s mental capacity at the time she executed the POAs. The legal framework for mental capacity in the context of powers of attorney requires that the donor understands, at the material time, the nature and effect of the transaction and the extent of the authority being conferred.
A second central issue was whether Kelvin had exercised undue influence over Mdm Liew to procure the execution of the POAs. Undue influence is typically analysed through whether there is a relationship of trust and confidence between the parties and whether the impugned transaction calls for an explanation. If such a presumption arises, the burden shifts to the alleged influencer to rebut it by showing that the transaction was the product of the donor’s free will.
Finally, the court also had to consider how the POAs should be construed—particularly the scope of authority and the practical consequences of the instruments—because the nature of the authority conferred is relevant to both the mental capacity inquiry and the undue influence analysis.
How Did the Court Analyse the Issues?
The court began by identifying the “central issue” as the validity of two POAs executed by an elderly woman in favour of her son, and it framed the analysis around two interlocking inquiries: mental capacity and undue influence. The judgment emphasised that the relevant time for capacity is the time of execution of the POAs, and that the evidence must be assessed in that temporal context.
On mental capacity, the court relied heavily on medical evidence. During a visit on 9 September 2017, Karen brought Mdm Liew to a neurologist, Dr Ho, who administered the Mini Mental State Examination (“MMSE”), a screening tool for dementia. Dr Ho’s evidence was that Mdm Liew scored 26/30, described as a “borderline abnormal” score. While the MMSE score alone does not conclusively determine legal capacity, it provided an important objective indicator of cognitive impairment risk in the period leading up to the POAs’ execution.
The court then considered the broader factual matrix surrounding Mdm Liew’s behaviour and functioning in the months after the MMSE. Karen’s evidence was that from around June 2017, Mdm Liew began exhibiting signs of mental decline and confusion. The judgment examined changes in behaviour across distinct time windows in 2017, including the first half, July to September, October to November, and December 2017 to February 2018. This structured approach mattered because it allowed the court to test whether the cognitive concerns were transient or progressive and whether they were likely to have affected Mdm Liew’s understanding at the time of execution.
In parallel, the court analysed undue influence using established principles. The court asked first whether the relationship between Kelvin and Mdm Liew was one of trust and confidence. It also asked whether the POAs “called for an explanation”, which is a concept used to identify transactions that are not naturally consistent with the donor’s prior intentions or ordinary expectations. The court considered the effect of the POAs: they shifted the Namly property’s sale proceeds away from Karen (who, under the father’s stated intentions and the LPA framework, was expected to benefit) and enabled the purchase of a condominium unit in joint names with Daniel, with an option for Kelvin to include himself as joint owner. Such consequences were significant and therefore relevant to whether the transaction was “explainable” by ordinary family arrangements or whether it required closer scrutiny.
Once the court considered whether a presumption of undue influence should arise, it examined whether Kelvin rebutted that presumption. The court’s analysis focused on the circumstances of execution, including the involvement of a lawyer and the extent to which the lawyer’s process ensured that Mdm Liew understood the nature and effect of the POAs. The judgment also assessed whether Kelvin’s conduct—particularly in relation to arranging the execution and communicating the instructions—was consistent with a scenario where Mdm Liew acted independently, or whether it suggested that Kelvin had dominated the decision-making process.
Although the judgment extract provided does not reproduce the full reasoning, the structure indicated that the court addressed “Actual undue influence” as well as the presumption-based framework. This suggests that, beyond the formal presumption analysis, the court evaluated the evidence for direct signs of coercion, manipulation, or domination. The court’s approach reflects the principle that undue influence may be established either by inference from the relationship and transaction or by proof of actual influence.
Finally, the court’s reasoning also integrated the agency dimension. Powers of attorney are a species of agency: they confer authority on an attorney to act on behalf of the donor. The court’s analysis of the POAs’ construction and the scope of authority was therefore not merely interpretive; it was also evidentially relevant to capacity and undue influence. The more extensive and consequential the authority, the more important it is that the donor understood what she was doing and that the transaction was not the product of another’s will.
What Was the Outcome?
The court declared that the two POAs executed by Mdm Liew in favour of Kelvin were invalid. The practical effect of this finding was that Kelvin’s authority to act under those POAs could not be relied upon to justify the impugned transactions. Given the earlier procedural history—where attempts to restrain the sale of the Namly property failed at the interlocutory stage and the sale proceeded—the court’s final orders would have been shaped by the need to provide effective relief despite the sale having already occurred.
In addition, the court’s decision confirmed that Karen, acting under the LPA and later as executrix, was entitled to challenge the POAs on the grounds of mental incapacity and undue influence. The judgment therefore provides a clear statement that where an elderly donor’s capacity is in doubt and the transaction is not sufficiently explained, the court will not uphold powers of attorney that are not supported by the requisite mental understanding and free will.
Why Does This Case Matter?
This case is significant for practitioners dealing with powers of attorney, especially in family disputes involving elderly donors and competing beneficiaries. It illustrates that the validity of POAs will be scrutinised through both a mental capacity lens and an undue influence lens. Even where a lawyer is involved in preparing the instruments, the court may still find that the donor lacked capacity or that undue influence was not rebutted, depending on the evidence of understanding and the circumstances of execution.
For lawyers advising attorneys, donors, or family members, the decision underscores the importance of robust safeguards at the time of execution. Practically, it suggests that the process should include careful explanation of the nature and effect of the POA, confirmation of the donor’s understanding of the consequences (including who benefits and how property will be dealt with), and contemporaneous documentation that can withstand later scrutiny.
For litigators, the judgment is also useful as an example of how courts structure evidence on capacity over time and how they apply the presumption-based framework for undue influence. The case demonstrates that courts will look beyond formalities and examine the real-world effect of the instruments, the donor’s cognitive trajectory, and the dynamics within the family relationship.
