Judgment Debtor Definition:

A person who is liable to pay a judgment rendered in money against him and payable to the judgment creditor, usually the successful plaintiff.

The judgment debtor is usually the defendant who lost the litigation where the judgment is an award of money payable by the defendant.

Thus, the Ontario Reciprocal Enforcement of Judgments Act:

"Judgment debtor means the person against whom the judgment was given, and includes any person against whom the judgment is enforceable in the place where it was given"

Or, this from the Manitoba Judgments Act:

"Judgment debtor means any person, whether plaintiff or defendant, against whom a judgment has been recovered, and includes a corporation...."

The person to whom the money is owed in regards to the enforcement of the judgment is called the judgment creditor.

French: débiteur judiciaire.
