Which action requires a guardian to act in line with the guardian's fiduciary responsibilities?

A guardian has a fiduciary responsibility to act in the best interests of their ward, which includes safeguarding the ward's assets. Ensuring that the ward's assets are properly insured is a crucial step in protecting those assets from loss or damage. This action demonstrates the guardian's commitment to preserving the ward's wealth and providing financial security, which is at the core of fiduciary duties.

The other options illustrate behaviors that do not align with a guardian's level of responsibility. Consulting with friends about financial decisions, for instance, may lead to conflicts of interest and undermine the guardian's obligation to make decisions solely based on the ward's best interests. Allowing the ward to manage their own assets can lead to situations where the ward may not be capable of making informed financial decisions due to their circumstances, which could result in financial harm. Disregarding the ward's financial history fails to acknowledge the importance of understanding the ward's past in order to make informed decisions that protect their current and future financial well-being. Thus, acting to insure the ward's assets is a clear demonstration of fulfilling fiduciary duties effectively.
