LEGAL UPDATES – CIVIL PROCEDURE – MENTAL HEALTH – HIGH COURT FREEZES ASSETS BEFORE MENTAL CAPACITY IS DETERMINED

1. Summary and Facts:

Ong Tjoei Aik Harold v Gan Siew Mui @ Gan Yook Hwa (F) & Ors [2026] 10 MLJ 115 concerned an 83-year-old mother diagnosed with dementia, whose properties and overseas shares were progressively transferred to two of her sons. A third son filed a Part X Mental Health Act 2001 inquiry into her capacity, together with an urgent ex parte application to freeze the remaining assets pending that inquiry.

2. Legal Issues:

• Whether the court may grant interim injunctive relief before any finding of incapacity under Section 52 of the Mental Health Act 2001.
• Whether the urgency and full-and-frank-disclosure thresholds for ex parte relief were satisfied.

3. Court’s Findings:

The High Court:

1. granted an interim injunction over the identified movable assets;
2. imposed notice requirements for immovable properties;
3. ordered the plaintiff to provide the usual undertaking as to damages; and
4. fixed the matter for an inter partes hearing.

• The power to grant interim relief comes not from the Mental Health Act itself, but from the High Court’s general jurisdiction under the Courts of Judicature Act 1964, the Specific Relief Act 1950 and Order 29 of the ROC 2012.
  • This jurisdiction may be exercised, with caution, in aid of Part X’s protective purpose so the inquiry is not defeated by dissipation.
• Urgency was made out for the movable assets (overseas shares, safe deposit box, CDS account) given unexplained recent dealings, but not to the same degree for land already protected by the Torrens system.
• Damages would not adequately compensate the estate, and the balance of convenience favoured relief that was the minimum necessary pending the inter partes hearing.

4. Practical Implications:

This decision confirms that concerned family members are not left to wait for a formal capacity finding before they can act to protect a vulnerable relative’s estate, provided the urgency and disclosure thresholds for ex parte relief are properly met.

• Where dissipation risk is shown, an ancillary Order 29 injunction can and should be sought alongside a Part X application, particularly for foreign or easily-liquidated assets.
• Courts will calibrate relief to the actual risk shown – broad, indiscriminate freezing orders covering assets already protected by land registration are unlikely to be granted in full.
• Practitioners should front-load the affidavit with the seven heads of disclosure required by Order 29 rule 1(2A) to withstand later challenge at the inter partes hearing.
