A legal guardian is a person who has been appointed by law to make decisions on behalf of another individual, usually because that person is unable to make those decisions for themselves. This could be due to age (minors), incapacity or disability. The role of the legal guardian is to protect and advocate for their ward's best interests in areas such as healthcare, education, living arrangements, and finances. In some cases, a legal guardian may also have authority over personal decisions like clothing choices, haircuts or entertainment options. The appointment of a legal guardian is usually made by a court after determining that it is in the best interest of the ward.
