Conservatorship is similar to guardianship in that it is a legal relationship between a protected person and one or more individuals appointed by the court to make decisions on behalf of the protected person. However, while a guardianship may encompass all personal affairs of a protected person, a conservatorship is limited to the management of the property and financial affairs of a protected person. As with guardianship, a conservatorship may be full, limited, temporary, or joint. 
A guardian is an entity appointed by a probate court and given power and responsibility to make certain decisions about the care of another individual. These decisions might include treatment decisions or where the individual should live. If the individual has a reduced life expectancy due to advanced illness, the guardian may have power to make an informed decision on behalf of the individual regarding receiving, continuing, discontinuing, or refusing medical treatment. 
A representative payee is an individual or organization appointed to receive benefits for someone who cannot manage his or her money. The main responsibilities of a payee are to use the benefits to pay for the current and foreseeable needs of the beneficiary and properly save any benefits not needed to meet current needs.
