Yes, a grandparent or other relative can be appointed as a temporary guardian if they meet the necessary requirements and are deemed capable of providing proper care and support for the dependent. In fact, appointing a close relative can be beneficial, as they are likely to have an existing relationship with the dependent and a better understanding of their needs. However, the legal guardian must still complete a "Temporary Guardianship Form" to formalize the arrangement and grant the relative temporary guardianship authority.
