Deciding on an administrator

This morning I had this idea of appointing Ying as the sole administrator in case anything happens to me.

She will have the full authority to handle and manage whatever I have in my name. Most share-holdings are already in her account. And also the joint bank account serves its good purposes. I also have credit cards debts to settle. Because I would not have too much assets or nett worth, there is no point splitting it. She will have to manage it according to the needs of any family members, any little help that might assist. She will have to do the needs assessment as the needs arise.

I repeat here that she will have the full authority and nobody can question her decisions.
