The main difference between a guardian and a welfare guardian is that a guardian's role is limited to a child's upbringing, while a welfare guardian's role is to make decisions for someone who can't make them for themselves.

• Guardians

Guardians are responsible for a child's care, growth, and upbringing, and have the same legal powers and responsibilities as the child's parents. Guardianship typically ends when a child turns 18. 

• Welfare guardians

Welfare guardians are appointed by the Family Court to make decisions for someone who can't make them for themselves. They act in the best interests of the person they represent, and can make decisions about their personal care, healthcare, and accommodation. However, they can't make decisions about property or money. 

Welfare guardians are usually appointed for a maximum of three years, but can be re-appointed for up to five years. The court will normally appoint a relative, but may appoint a volunteer if no suitable relative is available. Welfare guardians aren't paid, but they can claim reimbursement for reasonable expenses from the person they're acting for.
