regressus

In Solidarity the guarantor who pays the whole has regressus against his co-guarantors, that is to say, has a power of recovering from them contribution of their share of the debt: whereas the Correal debtor who pays has no regressus or right to contribution.

1875, Edward Poste, Gai Institutiones

Hence the pactum non petendo in rem of one correus debendi benefits the rest whenever on payment by one of them he woud have regressus against the others, for otherwise the pactum would be practically inoperative.

On July 30th 1541, at the entreaty of the king of Scots, the pope provides Reid to the Church of Orkney, void by the death of Robert Maxwell, with retention of the monastery of Kinloss and his other benefices and pensions and right of regressus.

The right of regressus allowed a prelate to resign a benefice, possibly retaining a large pension on its revenues, with the assurance that that he could reclaim the benefice and its revenues either when the new incumbent died or if the latter in turn resigned.
