  noun, suru verb, transitive verbThe legal sense: a deposition as sworn testimony or a formal statement given to investigators or a court. Think of witness statements and affidavits rather than anything physical.

• 預託よたくCommon
  suru verb, transitive verb, no-adjectiveDepositing or entrusting money, valuables and the like with a bank or other party. English "deposition" is rarely used this way — think "deposit" — so this is seldom the word you want.
