1-15-417. Claims of garnishee against plaintiff or defendant.
A garnishee may retain or deduct out of the property, effects or credits of the defendant in his hands all demands whether or not due against the plaintiff and against the defendant of which he could have availed himself if he had not been served as garnishee. The garnishee is liable for the balance only after all mutual demands between himself and the plaintiff and defendant are settled, not including unliquidated damages for wrongs and injuries. The verdict or findings, if any, and the judgment shall show against which party any claim is allowed, and the amount thereof.
