A. A trustee is under a duty to a beneficiary to keep and render clear and accurate accounts of the administration of the trust. If the trust is revocable, the trustee has a duty to account to the settlor only.
B. A trustee shall render to a beneficiary or his legal representative at least once a year a clear and accurate account covering his administration for the preceding year. His first annual account shall relate to the calendar year during which he became responsible for the trust property, or, at his option, the first accounting period of not more than twelve months and shall be rendered within ninety days after the expiration of that calendar year or accounting period. Each annual account shall show in detail all receipts and disbursements of cash and all receipts and deliveries of other trust property during the year, and shall set forth a list of all items of trust property at the end of the year.
C. A trustee upon the termination, revocation, or rescission of the trust, or upon his resignation or removal, shall render to a beneficiary or his legal representative his final account covering the period elapsed since his most recent annual account (or, should the trust have terminated, or have been revoked or rescinded, during the first year, the period elapsed since he became responsible for the trust property), and setting forth the same information required for annual accounts.
D. A written approval by a beneficiary or his legal representative of an account rendered by a trustee shall be conclusive against the beneficiary with respect to all matters disclosed in the account. If a beneficiary or his legal representative fail or refuse to approve in writing an account rendered by a trustee, a trustee may apply to the proper court for an approval contradictorily with a beneficiary. An approval obtained from the proper court is conclusive against a beneficiary with respect to all matters disclosed in the account so approved.
E. A trustee shall not be under a duty, to file his accounts with the court unless he is expressly required to do so by the trust instrument or by the proper court.
