The Globe talks to probate lawyers who say the register's office under Felix Arroyo is a mess - but that that's no change from the way it was under predecessor Patty Campatelli. The state trial-court system, which relieved Arroyo of his duties - but with pay - says it's found "serious deficiencies" under him, but won't say what they are. Arroyo wants a public investigation, but won't release the trial-court letter detailing the charges against him.
