Does the attorney you selected to handle your mom's affairs answer your questions on how to handle unreasonable siblings?

The attorney I selected to handle mom's affairs comes with high recommendations and this is an attorney that would handle her will; but when you raise a question about how to handle an unruly and hysterical sibling, you never hear back or at all. I understand this attorney's specialization but it raises concern not hearing back. Has anyone else experienced this and what did you do? He has not asked for a retainer yet but has answered questions willingly.
