(a) Except as otherwise provided in § 14.5-907 of this subtitle, a beneficiary may not bring a judicial action against a trustee for breach of trust more than 1 year after the date that the beneficiary or the representative of the beneficiary is sent a report that adequately discloses the existence of a potential claim for breach of trust and informs the beneficiary or the representative of the beneficiary of the time allowed for bringing a judicial action.

(b) A report adequately discloses the existence of a potential claim for breach of trust if the report provides sufficient information so that the beneficiary or representative knows of the potential claim or should have inquired into the existence of the claim.

(c) This section does not limit the time for bringing an action against a trustee for breach of trust committed in bad faith or with reckless indifference to the purposes of the trust or the interests of the beneficiaries.
