Successor agent

What it means

A power of attorney names an agent — sometimes called an attorney-in-fact — to act on the principal's behalf. A successor agent is named in the same document to step in if that person dies, becomes unable to act, or declines the role.

A successor is not a co-agent. A co-agent acts alongside the first agent from the beginning; a successor acts only once the first cannot.

Naming one costs nothing at the time of drafting, and it cannot be added later without the principal's capacity to amend the document.

Why it matters

Spouses routinely name each other and stop there. If the named agent dies first, or is incapacitated by the same event, the document has nobody to act under it and the family is back to a court appointment — which is the outcome the document was signed to prevent.

It matters more the further away the agent lives. A single named agent several states from the institutions involved is one delayed flight from an arrangement that does not work.

When you are likely to meet it

• When a power of attorney is being drafted or reviewed.
• When the named agent has died, become ill, or moved away.
• When an institution asks who is authorized to act and the only name on the document is unreachable.

How this varies by state

Whether co-agents must act together or may act alone, and how a successor's authority is proved to an institution, are set by state law and by the document's own wording.
