What defines guardianship?

Guardianship is defined as a legally enforceable arrangement that grants one individual (the guardian) the authority to make decisions on behalf of another individual (the ward) who is unable to make those decisions due to various reasons, such as incapacity or mental disability. This legal framework ensures that the rights and needs of the ward are protected by providing a structured process for decision-making.

In this context, the guardianship arrangement is formalized through legal proceedings, typically involving the court system, which establishes the guardian's responsibilities and the scope of their authority. This framework is significant because it allows for oversight and accountability, ensuring that the guardian acts in the best interests of the ward.

The other choices refer to more informal or temporary arrangements. A voluntary arrangement for support does not have the legal weight or enforceability that guardianship entails. Temporary guardianship can occur in emergencies, but it is not the complete definition of guardianship, which is generally intended to be a long-term arrangement. An informal understanding of care duties lacks the legal recognition and structure that define a guardianship relationship. Thus, option B accurately captures the essence of what guardianship is.
