Winning a case is worthless if the defendant has already moved the money. Thai civil procedure allows a claimant to ask the court, before judgment, to seize or attach the defendant's assets, to prohibit transfers, to suspend registration of property, and in extreme cases to detain the defendant. These are the most powerful tools in Thai litigation and the most frequently refused, because the court requires real evidence of an intention to defeat enforcement, not merely a worry that the defendant is in financial difficulty. A failed application can also expose the claimant to a compensation order. This guide explains what can be sought, what must be proved, and where applications fail.
