A guardian is the adult who is legally responsible for the needs of a minor. You may only become a guardian in California by being appointed by the court. A guardianship is required in certain situations for minors. There are basically two types of guardianships, “guardianship of the person” – meaning legal custody and responsibility for the minor, and “guardianship of the minor’s estate” – meaning legal responsibility to manage the minor’s assets. In many cases, you will only need to obtain a guardianship of the person, unless the minor has assets in excess of $5,000. If a minor receives an inheritance in excess of $5,000, that minor’s parent must be appointed by the court as the guardian of the estate for that child.
