Power of attorney
An instrument by which a grantor authorises an agent to act within a defined scope.
Authority: Issued by the grantor; the receiving body may prescribe its own form.
A power of attorney lets someone act within a stated scope, and the grantor must already hold that authority. A court order appointing an administrator confers statutory power over the estate. Heirs’ consent merely records that they do not object; it does not itself authorise a transfer. Registries and banks generally ask for the court order.

| Criterion | Power of attorney | Court-appointed administrator | Heirs’ written consent |
|---|---|---|---|
| Authority conferred | Only what the grantor holds and has expressly stated | Statutory power over the estate as set by law and the order | Confers no operative authority; records non-objection only |
| Issuer | The grantor | The court | Each heir individually |
| Effect once the owner has died | A POA the deceased gave is not a substitute for a court order over the estate | The principal basis registries rely on | Supports the file but does not replace the order |
| What banks and registries usually ask for | Useful for sub-steps, such as an agent filing on the administrator’s behalf | The court order plus any finality certificate the body requires | May be requested at the petition stage |
| When the signatory is abroad | Signature certification and the local certification chain are typically needed | The petitioner may appoint a representative to conduct the case in Thailand | Signatures likewise need certification for the court to accept them |
| Main risk | Scope drafted too broadly or too narrowly and then rejected | Incomplete proof of heirship delaying the case | A non-signing heir requiring additional proceedings |
