A more thorough explanation:

Ad colligendum bona defuncti is a Latin term used in law that means "for collecting the goods of the deceased." It refers to special letters of administration that authorize a person to collect and preserve a deceased person's property.

When someone dies, their property and assets need to be taken care of. If the deceased person had a will, the executor named in the will is responsible for managing their property. However, if there is no will or the executor is unable to perform their duties, a court may issue ad colligendum bona defuncti letters to someone else.

For example, if John dies without a will and his brother Tom wants to take care of his property, Tom can apply for ad colligendum bona defuncti letters. Once he has these letters, Tom can collect and preserve John's property, pay off any debts, and distribute the remaining assets to John's heirs.

Another example is if a person dies while they are abroad, and their family members need to collect their property and bring it back to their home country. In this case, the family members can apply for ad colligendum bona defuncti letters to legally collect and preserve the deceased person's property.

These examples illustrate how ad colligendum bona defuncti letters are used to authorize someone to collect and preserve a deceased person's property. Without these letters, it would be difficult for someone to legally manage the property of a deceased person.
