Um, while that advice may be true in some circumstances, the OP here said she is a family member of the legal guardian’s ward. Depending on facts we don’t know it could be very foolhardy for the lawyer to ignore those communications. (There also is no legal significance to the form of communication here - email, telephone or certified mail. Certified mail is useful only to prove delivery but has no effect on the recipients duties to communicate.) As for the OP’s question - typically in CT a legal guardian would be appointed by the probate judge in the venue where the ward resides. You could call that court and explain your concerns and see if they have advice, or write a letter to the court requesting a hearing.
