Rule 632 A thing delivered by one to another is presumed to have belonged to the latter.

If someone gives you an object, the court will assume that object was yours to begin with. In other words, the person receiving something is presumed to be the owner.

This can matter in legal disputes about property. If there is no other evidence about who owned something, the fact that it was handed over to you is enough for the court to assume it belonged to you. The other side would need to show proof that this assumption is wrong.
