Most people assume that being a spouse, child, or next-of-kin automatically gives them the right to manage a loved one’s finances or healthcare decisions if that person can no longer do so themselves.
It does not.
In Singapore, losing mental capacity without a Lasting Power of Attorney (LPA) in place can leave your family locked out of your bank accounts, unable to pay your bills, and facing a lengthy and expensive court process — all while you are still alive.
This article explains what mental capacity means under Singapore law, what happens when someone loses it without an LPA, and what you should do now to protect yourself and your family.
What Is Mental Capacity?
Mental capacity refers to a person’s ability to make decisions for themselves.
Under the Mental Capacity Act (MCA), a person lacks mental capacity if, at the relevant time, they are unable to:
- Understand the information relevant to a decision;
- Retain that information long enough to make a decision;
- Use or weigh that information as part of the decision-making process; or
- Communicate their decision (by any means).
Importantly, a person is not assumed to lack capacity just because they have a condition like dementia, a brain injury, or a psychiatric illness. Capacity is assessed decision-by-decision, not as a blanket label. Someone may have capacity to decide what to eat for lunch but not to manage a complex investment portfolio.
Common causes of lost capacity in Singapore include:
- Dementia and Alzheimer’s disease
- Stroke
- Traumatic brain injury
- Severe mental illness
- Prolonged unconsciousness
What Is an LPA?
A Lasting Power of Attorney is a legal document that lets you — while you still have mental capacity — appoint someone you trust (called a donee) to make decisions on your behalf if you ever lose that capacity.
There are two types of decisions your donee can be authorised to make:
1. Personal welfare — decisions about your day-to-day care, medical treatment, and where you live.
2. Property and affairs — decisions about your money, property, and financial matters.
You can grant one or both. You can also set conditions and restrictions on what your donee can and cannot do.
An LPA only takes effect when you have lost mental capacity. Until then, you remain fully in control.
What Happens If You Lose Capacity Without an LPA?
This is where things get difficult — and expensive.
This is where things get difficult — and expensive.
Your family cannot simply step in.
There is no automatic right for your spouse or children to manage your finances or make healthcare decisions on your behalf. Even a joint bank account has limits: banks may freeze or restrict access once they are notified that an account holder has lost capacity.
The only legal route is a court application for deputyship.
Without an LPA, anyone who wants to manage your affairs must apply to the Family Justice Courts to be appointed as your deputy under the MCA.
A deputy is essentially a court-appointed substitute decision-maker. The process involves:
- Filing an originating application with supporting medical evidence of incapacity
- Providing details of the proposed deputy and their relationship to you
- Potentially notifying other family members, who may object
- Attending court hearings
- Purchasing a security bond (a form of insurance to protect the person who has lost capacity)
- Ongoing reporting obligations to the court after appointment
It takes time — often months.
A deputyship application is not a quick fix. In straightforward cases, the process can take three to six months or longer. In contested cases — where family members disagree about who should be appointed or what decisions should be made — it can take much longer and cost significantly more.
During this time, your family may be unable to access funds to pay for your medical care, housing, or daily expenses.
It costs money.
Legal fees, court fees, and the cost of the security bond all add up. For a contested matter, costs can run into the tens of thousands of dollars.
Compare this to setting up an LPA, which costs a few hundred dollars and a few hours of your time.
A Possible Real-World Scenario
Consider this situation:
Mr Tan, 71, suffers a severe stroke and is hospitalised. He has no LPA. His wife wants to withdraw money from his sole bank account to pay the hospital bills and household expenses. The bank refuses — they cannot accept instructions from her because she has no legal authority over his account.
His children apply to court to be appointed as deputies. The application takes four months. During this time, the family has to fund expenses out of pocket. One sibling disputes who should be the primary deputy, complicating matters further.
Eventually, deputies are appointed. But the process has cost the family time, money, and considerable stress — at an already difficult time.
All of this could have been avoided with an LPA.
Frequently Asked Questions
Q: Can’t my spouse make medical decisions for me automatically?
No. Under Singapore law, there is no automatic right for a spouse to consent to medical treatment on behalf of an incapacitated partner. Without an LPA granting personal welfare powers, doctors will generally follow clinical guidelines and consult family members informally, but your spouse has no legal authority to make binding decisions on your behalf.
Q: What if I recover capacity?
An LPA automatically ceases to apply once you regain capacity. You remain in control when you have capacity; the LPA only operates when you do not.
Q: Can I revoke an LPA?
Yes. You can revoke an LPA at any time while you still have mental capacity, by executing a deed of revocation and notifying the Office of the Public Guardian (OPG).
Q: Who can be a donee?
A donee must be at least 21 years old. For property and affairs decisions, they cannot be an undischarged bankrupt. You should choose someone you trust completely — a spouse, adult child, sibling, or close friend. You can appoint more than one donee, and specify whether they must act jointly or can act independently.
Q: What if I don’t trust anyone enough to appoint as donee?
You can apply to have a professional deputy appointed — a lawyer or other qualified person. You can also appoint the Public Trustee for property and affairs matters. Speak to a lawyer about the options available to you.
Q: Is an LPA the same as a will?
No. A will deals with what happens to your assets after you die. An LPA deals with who can make decisions while you are alive but unable to decide for yourself. You need both.
How to Make an LPA in Singapore
Making an LPA involves the following steps:
- Choose your donee(s) and discuss the role with them. They must agree to act.
- Choose the scope — personal welfare, property and affairs, or both. Consider any specific conditions or restrictions you want to include.
- Complete the prescribed LPA form — either Form 1 (standard powers, simpler) or Form 2 (customised powers, requires a lawyer to draft).
- Have the LPA certified by an authorised certificate issuer — this must be a practising lawyer, psychiatrist, or accredited medical practitioner. The certificate issuer will confirm that you understand the document and are not being pressured.
- Register the LPA with the Office of the Public Guardian. Registration takes approximately three to four weeks. The LPA is not valid until it is registered.
The OPG periodically offers fee subsidies for LPA registration. Check the OPG website for current rates.
The Bottom Line
An LPA is one of the most important legal documents you can have — and one of the most commonly overlooked.
It is not just for the elderly. Accidents and sudden illness can happen at any age. Having an LPA in place means that someone you trust can step in immediately, without court involvement, to take care of you and your finances.
Without one, your family faces a court process that is slow, costly, and stressful — at precisely the moment when they can least afford it.
If you do not have an LPA, the best time to make one is now, while you still have capacity to do so.
