A temporary administrator is someone appointed to manage a person's estate for a limited time, often while other matters get sorted out. This rule explains what happens if someone believes the estate owes them money and wants to get paid while that temporary administrator is in charge.
Under this rule, a person who has a claim against the estate can ask the court to make the temporary administrator explain why the claim hasn't been paid. The court will look at the situation and decide what to do. It might throw out the claim entirely, or it might order the temporary administrator to pay all or part of what's owed.
If the court does order payment, it can also require the person receiving the money to sign a refunding bond. This is basically a promise, backed by money, that they'll pay the money back later if it turns out they weren't actually entitled to it. This protects the estate in case the full picture of debts and assets changes once a permanent administrator or executor takes over.
