Is the expiation for an oath performed on behalf of a deceased person?

The questioner:
A person says: A man passed away and he had an oath upon him. Do his sons perform this oath on his behalf after his death, given that...?

The Shaykh:
A man. He passed away and he had an oath upon him. I mean, the expiation for an oath. It appears to be the performance of the oath. Yes, he is asking about the expiation; he had an expiation for an oath upon him. No, that is not it. If he died, the way to handle his oath is: if he had an expiation due and did not perform it, it is performed on his behalf. Yes.

The questioner:
He says: We swear on his behalf. Is it permissible for us to swear on his behalf?

The Shaykh:
He had an oath, what kind? It was not specified. They said it was before the judge. This is what appears to be the case, yes. That is it, the dispute is over. If the party in the dispute dies, the dispute ends, unless he was an agent, yes.
