Is it permissible to pay the lawyer's fees from the deceased's estate if a lawsuit is filed against the executor?

If filing a lawsuit against a guardian aims to protect the interests of the ward and necessitates hiring a lawyer and paying his fee from the endowment's funds, then the matter rests with the ruler who has the authority to dismiss the guardian and appoint another. If the guardian's condition changes due to insanity, apostasy, imprudence, or immorality, his guardianship ceases, and the matter reverts to the ruler to appoint a trustworthy guardian. If his dismissal or the establishment of a reason for his dismissal requires paying a lawyer's fee from the endowment's funds, and the ruler deems it to be in the ward's interest, then there is no objection.
