One who is given the lawful custody and care of another (called a ward). The ward might be a minor, an insane person or a spendthrift. The guardian may upon court approval sell the ward’s property, if it is in the best interest of the ward. The grantee would receive valid title under a guardian’s deed. A “Guardian Ad Litem” is one appointed by a court to bring or defend a legal action on behalf of his ward.
