Therefore, it's advisable to seek impartial legal advice and guidance from, for example, a lawyer or legal aid before deciding to grant a power of attorney. At a minimum, it's crucial to have a thorough conversation with the person you're granting the power to so they understand your wishes. Documenting the agreement is essential.
