A more thorough explanation:

A custodian is a person who is responsible for taking care of something. This can include managing property or assets, enforcing liens, or general administration of property for the benefit of creditors.

• Under the Uniform Transfers to Minors Act (UTMA) and Uniform Gifts to Minors Act (UGMA), a custodian is a person named to manage property left or given to a child until they reach the age specified by state law.
• In the context of bankruptcy, a custodian can be a receiver, trustee, assignee, or agent appointed to take charge of property for the purpose of enforcing a lien or general administration for the benefit of creditors.
• A school custodian is responsible for maintaining and cleaning the school building and grounds.

These examples illustrate how a custodian can have different responsibilities depending on the context. In all cases, however, a custodian is someone who has been entrusted with the care and management of something valuable.
