If you have money or property that's part of a lawsuit, you can ask the court to hold onto it while the case is being decided. This is helpful when there's a dispute over who the money or property belongs to, and you don't want to be responsible for holding it yourself. To do this, you need to let the other people in the case know you're asking the court to take custody of it.
Once the court agrees to hold the money, it can be placed in an account or invested so it doesn't just sit there losing value. This protects the money while the case moves forward and makes sure it's available once the court decides who should get it.
This rule is often used in cases involving insurance payouts, disputed contracts, or property that multiple people claim rights to. It gives everyone a neutral way to handle the money until a judge sorts out who is entitled to it, instead of one side holding onto funds that might be owed to someone else.
