Mental capacity assessments play a crucial role in ensuring that individuals who may face difficulties in managing their personal affairs receive the right support. In Singapore, these assessments are essential for applications related to deputyship and the activation of Lasting Power of Attorney (LPA). Navigating these processes can be complex, but understanding the purpose, criteria, and procedures involved can help individuals and families make informed decisions.

What Is Mental Capacity Assessment?
Mental capacity assessment evaluates a person’s ability to make decisions about their personal welfare, property, and financial matters. It determines whether an individual can understand, retain, and weigh relevant information to make informed choices. This assessment is vital when there are concerns about cognitive impairments due to conditions such as dementia, stroke, or other mental health issues.
In Singapore, mental capacity assessments are often required for legal processes like deputyship applications and activating an LPA, which allow trusted individuals to manage affairs on behalf of someone who lacks capacity.
Why Mental Capacity Assessment Matters for Deputyship and LPA
Deputyship Applications
Deputyship is a legal arrangement where the Court appoints a deputy to manage the personal and financial matters of someone who cannot do so themselves. This process requires a formal mental capacity assessment to prove that the individual lacks the capacity to make decisions independently.
There are two types of deputyship applications:
Simplified Deputyship Application
This applies when the person only needs help managing their property and financial affairs. It is a quicker process with less documentation.
Standard Deputyship Application
This is necessary when the person requires assistance with both personal welfare and financial matters. It involves a more detailed assessment and court process.
Activation of Lasting Power of Attorney (LPA)
An LPA allows a person (the donor) to appoint one or more attorneys to make decisions on their behalf if they lose mental capacity in the future. Before an LPA can be activated, a mental capacity assessment confirms that the donor no longer has the ability to make decisions independently.
Without a valid assessment, attorneys cannot legally act on behalf of the donor, which could delay critical decisions about healthcare or finances.
The Mental Capacity Assessment Process in Singapore
The assessment is conducted by qualified medical professionals, typically psychiatrists or doctors trained in mental capacity evaluation. The process involves:
Referral and Appointment
The individual or their family arranges an appointment with a medical centre offering mental capacity assessments, such as MyHealth Medical Centre.
Clinical Evaluation
The doctor reviews medical history, conducts cognitive tests, and interviews the individual to assess understanding, reasoning, and decision-making abilities.
Report Preparation
The doctor prepares a detailed report outlining the findings, including whether the individual has the capacity to make specific decisions.
Submission to Authorities
For deputyship applications, the report is submitted to the Court. For LPA activation, it is shown to whatever relevant authority that the donee needs to act on behalf of the donor together with sharing the LPA by the Office of Public Guardian website.
The entire process can take a few weeks, depending on the complexity of the case and the availability of medical professionals.
Criteria Used in Mental Capacity Assessments
Doctors assess capacity based on the individual’s ability to:
Understand information relevant to the decision
Retain that information long enough to make the decision
Use or weigh the information to arrive at a choice
Communicate the decision clearly
Capacity is decision-specific and can vary over time. A person may have capacity for some decisions but not others.

Common Misconceptions About Mental Capacity Assessments
Assessment means loss of all decision-making rights
Capacity is decision-specific. Losing capacity for financial matters does not mean losing capacity for personal care decisions.

Mental capacity issues can affect anyone with cognitive impairments, including younger adults with brain injuries or mental illnesses.
The process is quick and simple
Assessments require thorough evaluation and documentation, which can take time.
Family members can act without assessments
Legal authority to act on behalf of someone else requires proper court orders or activated LPA, both needing valid assessments.
Mental capacity is permanent
Capacity can fluctuate. Regular reviews may be necessary.
