How Can a Property Be Sold When the Owner Has Lost Mental Capacity?

The Problem: When an Owner Can No Longer Sign

Consider the following scenario, which reflects a situation our firm has encountered: a father who had agreed in principle to sell his property to relatives began showing signs of cognitive decline in 2017. By the time the intended purchasers had gathered the necessary funds, his condition had deteriorated to the point where he was unable to understand the contents of a sale and purchase agreement or execute any legal documents. His solicitor declined to witness his signature, as the owner could not demonstrate the requisite understanding of the transaction. This presents a genuine legal difficulty. A sale and purchase agreement requires the vendor to have the mental capacity to contract. Where that capacity is absent, neither the vendor nor any family member may unilaterally sign on his behalf without proper legal authority.

Under the Mental Health Act 2001 and the Rules of the High Court, the appropriate legal mechanism is to apply to the High Court of Malaya for the appointment of a Committee of the Estate (known in Bahasa Malaysia as Jawatankuasa Harta). Once appointed, the Committee is authorised by the court to manage all financial and property affairs of the incapacitated person, including the execution of property transactions on their behalf.

Who May Be Appointed?

The Committee of the Estate is typically constituted by two or more family members who are willing and able to act in the best interests of the incapacitated person. The court will assess the suitability of the proposed members. In most cases, close family members such as spouses, adult children, or siblings are appointed.

What Can the Committee Do?

Once appointed by the High Court, the Committee has the legal authority to:

  • Execute sale and purchase agreements and other property documents on behalf of the incapacitated owner;
  • Manage the incapacitated person’s bank accounts, investments, and other assets;
  • Settle debts and liabilities owed by the incapacitated person;
  • Make decisions regarding the incapacitated person’s property in their best interests.

All actions taken by the Committee remain subject to the supervision and oversight of the High Court.

The Application Process: Step by Step

Step 1 Obtain Medical Evidence

The application must be supported by a medical report from a registered psychiatrist or medical practitioner confirming that the person in question lacks the mental capacity to manage their own affairs. This report is a prerequisite for the court application and should be obtained as early as possible.

Step 2 Engage a Solicitor

A solicitor must be engaged to prepare and file the originating summons and supporting affidavits in the High Court. The application will set out the identity of the proposed Committee members, the nature of the incapacitated person’s assets, and the specific transactions or matters requiring the Committee’s authority.

Step 3 File the Application at the High Court

The application for the appointment of a Committee of the Estate is filed at the High Court of Malaya. The court will fix a hearing date and may require the attendance of the applicants. In straightforward cases where there is no dispute among family members, the process is generally more expedient.

Step 4 Obtain the Court Order

Upon satisfaction of the application, the High Court will issue an order formally appointing the named individuals as the Committee of the Estate. This order confers full legal authority on the Committee to act on behalf of the incapacitated person in all property and financial matters specified therein.

Step 5 Proceed with the Property Transaction

With the court order in hand, the Committee may proceed to execute the sale and purchase agreement and all related transaction documents on behalf of the incapacitated owner. The solicitor handling the property transaction will require a certified copy of the court order before proceeding.

A Note on Lasting Power of Attorney

It is worth noting that the Committee of the Estate application arises precisely because no prior legal planning was put in place. Had the property owner — while still mentally capable — executed a Lasting Power of Attorney (LPA) or an Enduring Power of Attorney, a trusted person could have been authorised in advance to manage his affairs upon loss of capacity, without the need for a court application. This underscores the importance of advance estate planning. Families are strongly encouraged to consult a solicitor to prepare appropriate documents while their loved ones retain full mental capacity.

Conclusion

Where a property owner has lost mental capacity, the proper legal avenue is to apply to the High Court for the appointment of a Committee of the Estate. This process, while procedurally involved, provides the legal authorisation necessary to manage the incapacitated person’s affairs — including the completion of property transactions — in a manner that is both lawful and protective of that person’s interests.
