You usually need probate even when a valid will exists. Thai banks, the Land Office, and most institutions require a court order before releasing assets.
A will guides the court and confirms how the estate should be distributed, yet it does not give automatic legal authority to act. The Thai court must still appoint an estate administrator who then holds the legal right to access accounts, deal with property and manage the estate. A Thai will is normally accepted quickly. A foreign will requires translation and legalisation before the court can review it.
