Summary
In BUV v BUU and another and another matter [2019] SGHCF 15, the High Court (Aedit Abdullah J) determined an interrelated set of applications arising from a family dispute over an elderly mother’s property and affairs. The core issue was whether the mother (UWP) lacked mental capacity under Singapore’s Mental Capacity Act (the “MCA”) to make decisions relating to her personal welfare and property and affairs, and whether deputies should be appointed to make decisions on her behalf.
The court found that UWP lacked mental capacity at the material time because of an impairment or disturbance in the functioning of her mind. The decision was grounded in medical evidence from court-appointed experts, with the judge expressing a preference for the evidence of a psychiatrist (Prof Kua) over that of a neurologist (Dr Tang), and also taking into account the judge’s concerns arising from UWP’s testimony in court. The court further held that the incapacity affected the mother’s ability to give instructions for the related civil proceedings and to execute the relevant instruments, including a lasting power of attorney (LPA) and a will executed in 2016.
On the consequential question of who should act as deputies, the court initially adjourned to resolve practical difficulties and potential conflict. Ultimately, the judge appointed the mother’s youngest daughter and daughter-in-law as joint deputies, granting them liberty to write to the court for directions if issues arose.
What Were the Facts of This Case?
The dispute involved four principal actors: (i) the plaintiff/applicant BUV (a son), (ii) BUU (the eldest son), (iii) UWP (the mother), and (iv) BXD Bank (the bank holding the relevant account). The case began with a civil suit (OS 1096/2016) brought by UWP against BUV and the bank. UWP was 89 years old at the time of the application and sought orders relating to monies held in a bank account.
In mid-2016, a bank account was jointly opened in the names of UWP, BUU, and BUV. Shortly thereafter, UWP executed testamentary and decision-making instruments. She executed a declaration of intention dated 21 June 2016 and a lasting power of attorney dated 21 June 2016 (registered on 29 November 2016). The earlier will dated 25 August 2005 was ineffective due to non-compliance with formalities. A later will dated 20 July 2016 (the “2016 Will”) disposed of her assets in specified proportions, with the bulk of the remaining monies going to BUU after debts were paid out of the estate.
UWP’s testamentary capacity and the validity of the instruments became contested. Letters of demand were sent to BUV and culminated in the commencement of OS 1096/2016 on 25 October 2016. In that civil suit, UWP sought declarations that she was the legal and beneficial owner of the monies in the bank account and sought an order that the bank account be closed and the monies returned to her. The litigation thus raised not only property questions, but also the underlying question of UWP’s capacity to manage her affairs and to give instructions.
BUV attempted to obtain a medical examination of UWP’s mental capacity to commence proceedings in OS 1096/2016. That application was denied on 22 December 2016 because the evidence was insufficient to justify infringing her autonomy in the manner prayed for. However, BUV later filed an MCA application on 19 January 2017 (OSM 1/2017), seeking declarations that UWP lacked capacity to make decisions about her personal welfare and property and affairs due to impairment or disturbance in the functioning of her mind or brain, and seeking the appointment of deputies to make decisions on her behalf.
What Were the Key Legal Issues?
The first key issue was whether UWP lacked mental capacity under the MCA in relation to decisions about her personal welfare and her property and affairs. This required the court to apply the MCA’s statutory test for “lack of capacity” and to determine whether, at the material time, UWP was unable to make the relevant decisions for herself because of an impairment or disturbance in the functioning of her mind or brain.
A second issue concerned the legal consequences of the court’s capacity finding. The plaintiff sought not only declarations and deputyship orders, but also relief that would affect the validity or effect of the 2016 LPA and the 2016 Will. The court therefore had to consider how the finding of incapacity impacted UWP’s ability to execute those instruments and to give instructions in the related civil proceedings.
A third issue was practical and institutional: who should be appointed as deputies, and whether the proposed deputies could be trusted to act in the mother’s best interests without undue conflict. The court had to balance the statutory framework for deputy appointment with the realities of family dynamics, including evidence of factionalism and alleged influence within the family.
How Did the Court Analyse the Issues?
The court approached the MCA application as the primary matter and treated the civil application as interrelated. The legal framework was anchored in the MCA provisions invoked by the plaintiff: s 17 (court powers relating to the validity of LPAs), s 19 (declarations as to whether a person has or lacks capacity to make specific decisions and the lawfulness of acts done), and s 20 (powers to make decisions for persons lacking capacity and to appoint deputies). The judge also referenced the statutory definition of lack of capacity in s 4(1), which focuses on whether the person is unable to make a decision for herself at the material time because of an impairment or disturbance in the functioning of the mind or brain.
On the evidence, the court heard from two court-appointed medical experts: Prof Kua, a psychiatrist, and Dr Tang, a neurologist. In addition, a neuropsychologist, Dr Yeo, provided evidence based on psychological testing. The judge’s reasoning indicates that the court treated the medical evidence as central to the capacity assessment, but not as the only factor. The court also considered lay evidence from family members and, importantly, the judge’s own observations of UWP’s performance and responses in court.
Although the defendants argued that UWP did not lack capacity despite dementia and relied on earlier medical evidence from 2016, the judge was satisfied that UWP lacked mental capacity for decisions relating to personal welfare and property and affairs. The court placed particular weight on Prof Kua’s evidence. The judge stated that he generally preferred Prof Kua’s evidence to Dr Tang’s, and that there was sufficient medical evidence indicating that UWP did not have sufficient capacity. This preference is significant: it reflects the court’s evaluation of expert credibility and the relevance of the experts’ assessments to the statutory capacity test, rather than simply choosing the expert who concluded “capacity” or “incapacity”.
The judge also considered the content and implications of UWP’s testimony. The judgment records that UWP’s evidence caused “considerable concern” as to her capacity. This is consistent with the MCA’s functional approach: capacity is not assessed by diagnosis alone, but by whether the person can understand, retain, use, and weigh relevant information and communicate decisions. The court’s concerns about UWP’s ability to engage with the decision-making process supported the conclusion that she was unable to make the relevant decisions at the material time.
Having found incapacity, the court addressed the downstream effects. The judge held that the lack of capacity affected UWP’s ability to execute the 2016 Will. The reasoning also extended to the 2016 LPA. While Prof Kua testified that the 2016 LPA could have been properly made by UWP, the judge found that UWP did not have the capacity to do so. This illustrates that the court’s conclusion on capacity was not mechanically tied to any single expert’s view; rather, it was the court’s own application of the MCA test to the evidence, including the judge’s assessment of UWP’s functioning and the overall evidential picture, that determined the outcome.
The court further found that incapacity affected UWP’s ability to give instructions for OS 1096/2016 and to litigate it. This is an important practical point for practitioners: where capacity is in issue, the court may treat the inability to give instructions as part of the broader incapacity analysis, with consequences for the validity and propriety of ongoing proceedings.
Finally, the court dealt with deputy appointment. The plaintiff had sought appointments of the plaintiff and the daughter-in-law as deputies. The judge found that these appointments were “difficult” and adjourned the determination to arrive at a workable solution, extending time for appeal in the meantime. This reflects the court’s duty to ensure that deputyship arrangements are not only legally permissible but also practically workable and aligned with the person’s best interests.
What Was the Outcome?
The court determined that UWP lacked mental capacity under the MCA in relation to decisions about her personal welfare and property and affairs due to impairment or disturbance in the functioning of her mind. The finding had consequential effects on the related civil proceedings and on the instruments executed in 2016, including the 2016 Will and the 2016 LPA, insofar as UWP’s incapacity undermined her ability to execute and instruct.
On deputyship, after adjourning to resolve practical difficulties, the court appointed UWP’s youngest daughter and daughter-in-law as joint deputies on 1 November 2018. The deputies were granted liberty to write in to the court for directions if issues arose in the course of their duties. This ensured ongoing judicial oversight while enabling the deputies to act without constant recourse to fresh proceedings.
Why Does This Case Matter?
BUV v BUU is a useful authority for lawyers and law students because it demonstrates how the High Court applies the MCA’s functional test for capacity in a contested family setting. The case shows that capacity determinations are evidence-driven and require careful evaluation of expert testimony, but they also incorporate the court’s assessment of the person’s actual ability to engage with decision-making. Practitioners should note the court’s willingness to prefer one expert’s evidence over another and to reach a conclusion that may differ from an expert’s view on whether a particular instrument was properly made.
The decision is also instructive on the relationship between capacity findings and the validity or effect of legal instruments and ongoing litigation. Where a person lacks capacity, the court may treat the incapacity as affecting the person’s ability to execute LPAs and wills and to give instructions in proceedings. This has direct implications for estate planning disputes, bank account disputes, and challenges to authority where the alleged decision-maker’s capacity is contested.
From a procedural and practical standpoint, the case highlights the importance of deputyship arrangements that are workable in real life. The court’s adjournment and eventual appointment of joint deputies reflects a pragmatic approach to managing conflict and ensuring that decisions are made in the protected person’s best interests. For practitioners, this underscores that deputy appointment is not merely a formal step; it is a governance mechanism that must function effectively amid family dynamics.
