Nothing in this article shall be construed to abridge the power of any court to require trustees to file an inventory, to account, to exhibit the trust property, or to give beneficiaries information or the privilege of inspection of trust records and papers, at times other than those herein prescribed; and nothing in this article shall be construed to abridge the power of such court for cause shown to excuse a trustee from performing any or all of the duties imposed on him or her by this article.

Nothing in this article shall prevent the trustee from accounting voluntarily when it is reasonably necessary, even though the trustee is not required to do so by this article or by court order. And nothing in this act shall require a trustee to qualify or to file an inventory or any accounting when the devise or bequest is to any governmental unit or department or solely for religious, charitable, or educational purposes, or for the maintenance of a cemetery or any part thereof or a place of burial, unless the court for good cause shown, or the will shall so require.
