Use "depositor" in a sentence
"By law, the depositor is the one responsible for any deposits he makes, so unfortunately you're stuck with the bill."
"For example, a big bank has been required to keep a higher level of cash reserves than a small bank, although the risk to the depositor is obviously in the other direction."
"A gratuitous deposit for the sole benefit of the depositor is a much stronger case for the denial of these remedies to the depositary; yet we have a decision by the full court, in which Lord Ellenborough also took part, that a depositary has case, the reasoning implying that a fortiori a borrower would have trespass."
