What is the ruling on the action of the eldest daughter who holds a general power of attorney for her mother, and is being pressured by her divorced sister to sign a procedure related to the mother's pension without the mother's knowledge and approval, while knowing her mother's complete refusal of the matter?

The trustee must safeguard and fulfill the trust exactly as it is; for safeguarding it is a matter of faith, and betraying it is an act of hypocrisy. Therefore, the daughter should not dispose of her mother's pension except with her permission.

If the divorced sister does not find sufficient support, it is obligatory for the wealthy mother to spend on her daughter. If she refuses, then it is permissible for the divorced sister to take from her mother's money what suffices her, within reasonable bounds, without her knowledge.

However, this should not involve forgery in pension documents, nor should it be with the assistance of the entrusted elder sister, as this contradicts her trust.

The elder sister must refrain from forgery and betrayal of trust. And if her sister's maintenance is obligatory upon her mother, then she should advise her mother about the obligation of providing maintenance, and she is not permitted to take money without the mother's knowledge to give it to her sister.
