A legal guardian is a person who has the legal authority (and the corresponding duty) to care for the personal and property interests of another person, called a ward. Usually, a person has the status of guardian because the ward is incapable of caring for his or her own interests due to infancy, incapacity, or disability. Most countries and states have laws that provide that the parents of a minor child are the legal guardians of that child, and that the parents can designate who shall become the child's legal guardian in the event of their death.
Some jurisdictions allow a parent of a child to exercise the authority of a legal guardian without a formal court appointment. In such circumstances the parent acting in that capacity is called the natural guardian of that parent's child.

A guardian is a fiduciary and is held to a very high standard of care in exercising his powers. If the ward owns substantial property the guardian may be required to give a surety bond to protect the ward in the event that dishonesty or incompetence on his part causes financial loss to the ward.
In some jurisdictions a legal guardian is called a conservator or custodian. Many jurisdictions and the Uniform Probate Code distinguish between a "guardian" or "guardian of the person" who is an individual with authority over and fiduciary responsibilities for the physical person of the ward, and a "conservator" or "guardian of the property" of a ward who has authority over and fiduciary responsibilities for significant property (often an inheritance or personal injury settlement) belonging to the ward. Some jurisdictions provide for public guardianship programs serving incapacitated adults or children.
