A more thorough explanation:

Quando acciderent is a Latin term that refers to a legal judgment entered against a deceased person's personal representative. This judgment is to be paid out of the assets that the representative receives after the judgment.

For example, if a person dies and leaves behind debts, their personal representative (such as an executor or administrator) may be held responsible for paying those debts out of the assets of the deceased person's estate. If the representative fails to do so, a quando acciderent judgment may be entered against them, requiring them to pay the debts out of their own pocket.

Another example might be if a personal representative is found to have mismanaged the assets of the estate, resulting in financial losses. In this case, a quando acciderent judgment could be entered against them, requiring them to repay the losses out of their own funds.

These examples illustrate how a quando acciderent judgment can hold a personal representative accountable for their actions and ensure that the debts and obligations of the deceased person's estate are properly paid.
