Other forms: conservatorships
When a judge appoints a guardian to manage another person's money, it's called a conservatorship.
When a court establishes a conservatorship, it's meant to protect someone who is unable to care for themselves or make their own financial decisions. That can be because they're too young, or because they have a mental illness or a condition like dementia. A conservatorship can be an elderly person's grown child managing their finances, or a guardian assisting someone who has developmental disabilities. The Latin root of conservatorship means "keeper" or "defender."
