Durable Power of Attorney (DPOA)

A durable power of attorney, or DPOA, is a document in which a person, called the principal, authorises an agent to act on financial, legal, or property matters. Its defining feature is that the authority is designed to continue if the principal later loses capacity. The document may grant broad powers or limit the agent to specified accounts, entities, transactions, or periods.

The names, execution requirements, permitted powers, and rules on when authority begins vary by jurisdiction. Some documents take effect immediately, while others are designed to become effective only after a defined incapacity process. A financial DPOA generally does not authorise healthcare decisions, which are covered through separate documents under local law.

Why it matters for family offices

Complex family wealth cannot be managed if no authorised person can sign, instruct a bank, handle a tax filing, or exercise ownership rights during a principal's incapacity. A valid, current DPOA can reduce that interruption, provided that its powers cover the required action and the receiving institution accepts it. It does not transfer ownership or permit the agent to disregard duties owed to the principal.

Family offices need to know which documents exist, where originals are held, which agents are appointed, and whether the powers fit the current structure. A document signed years before a new holding company or banking relationship was created may not work as expected. Local counsel typically reviews validity, conflicts, gifting powers, digital assets, and cross-border recognition.

How it shows up in practice

Suppose a family principal suffers a sudden illness and cannot manage financial affairs. The appointed agent needs to pay property costs, communicate with investment managers, and sign documents for a company interest. The family office retrieves the relevant DPOA, confirms with counsel that it is effective, and provides certified copies to the institutions involved. Each institution reviews the authority under its own procedures.

The office records which powers were used and keeps the principal's assets separate from the agent's. A healthcare decision remains with the person authorised under the applicable healthcare document. Preparation does not eliminate every delay, especially across jurisdictions, but it gives the family a documented route to keep essential financial administration running.
