Hong KongIncapacity planning: the documents nobody wants to discuss
A durable power of attorney appoints a financial agent whose authority survives incapacity. A healthcare proxy appoints a medical decision maker. Without them, a court-appointed guardianship or conservatorship is the only route.
More clients become incapacitated than face estate tax, and far more plans address the second than the first.
The financial power
| Type | What it does |
|---|---|
| General | Broad authority, ends on incapacity unless durable |
| Durable | Survives incapacity - the essential feature |
| Springing | Takes effect only on incapacity, requiring certification |
| Limited or special | Authority for a specific transaction or period |
Durable is the one that matters. A power that ends when the principal loses capacity ends exactly when it was needed, which is not a subtle drafting point.
A springing power sounds safer and creates friction: someone must certify incapacity, and financial institutions can be slow to accept the certification when a decision is urgent.
The healthcare documents
A healthcare proxy appoints the decision maker. An advance directive states treatment wishes. A HIPAA authorization lets the agent obtain medical information at all.
The HIPAA authorization is the one omitted most often, and without it an agent can be appointed and still be told nothing.
A court proceeding for guardianship or conservatorship. Public, slow, expensive, and the judge appoints whoever seems appropriate - which may not be who the client would have chosen. Every incapacity document exists to avoid that.
Choosing the agent
- Someone trustworthy, and available.
- Someone geographically close enough to act.
- A successor named, in case the first cannot serve.
- The financial and healthcare roles considered separately.
- The person actually asked beforehand.
The last is not a legal requirement and it prevents a real problem. Agents who discover their appointment in a hospital corridor are not well placed to act.
The trust alternative
A funded revocable trust with a successor trustee provides incapacity management for the trust assets, and institutions accept a trustee more readily than an agent under a power of attorney.
It does not replace the power of attorney, because assets outside the trust still need one. The two work together.
Reviewing them
Documents more than a few years old should be refreshed. Institutions sometimes resist old powers, statutory forms change, and the named agent may no longer be appropriate after a divorce, a death, or a falling-out.
A question describing a document executed fifteen years ago is usually pointing at that.
The transfer tax exclusion was changed by the 2025 reconciliation act and is indexed thereafter. Confirm the current figure before relying on it, and check state law separately.
Common questions
What is a durable power of attorney?
A financial power whose authority survives the principal's incapacity. A non-durable power ends exactly when it becomes useful, which is why durability is essential.
What is a springing power?
One taking effect only on incapacity. It sounds safer and creates friction, because someone must certify the incapacity and institutions can be slow to accept it.
What is a HIPAA authorization for?
It allows the healthcare agent to obtain medical information. Without it an agent can be appointed and still be told nothing, and it is the document most often omitted.
What happens without incapacity documents?
A court-appointed guardianship or conservatorship - public, slow, expensive, and with the judge choosing the decision maker rather than the client.
Does a revocable trust replace a power of attorney?
No. A funded trust with a successor trustee manages trust assets during incapacity, but assets outside the trust still need a power of attorney. The two work together.
