A more thorough explanation:

LETTERS AD COLLIGENDUM BONA DEFUNCTI

Letters ad colligendum bona defuncti is a legal document that authorizes a person to collect and manage the assets of a person who has died without leaving a will. These letters are issued by a judicial officer only when there is no representative or creditor to perform this task.

• After her father passed away without a will, Jane was granted letters ad colligendum bona defuncti to manage his estate.
• The court issued letters ad colligendum bona defuncti to John, allowing him to collect and distribute the assets of his deceased neighbor who had no heirs.

These examples illustrate how letters ad colligendum bona defuncti are used to authorize a person to manage the assets of someone who has died without leaving a will.
