Right to petition for trust information enables interested parties to obtain particulars and audited account directions. Any person having an interest in an express or constructive trust for a public charitable or religious purpose may petition the Court within whose local jurisdiction any substantial part of the trust is situated to compel trustees to furnish particulars as to the nature and objects of the trust, the value, condition, management, application and income, and to direct that the trust accounts be examined and audited, subject to a statutory limitation on retrospective account claims.
