Del. Code tit. 12, §§ 61-413

Upon request of the income beneficiary, if the trustee determines that the assets of a trust consist substantially of property that does not provide the income beneficiary with a reasonable income from or use of the trust assets, and that the amounts that the trustee transfers from principal to income under § 61-104 of this title and distributes to the income beneficiary from principal pursuant to the terms of the trust are insufficient to provide the income beneficiary with the beneficial enjoyment of the income interest, the trustee shall make such property productive of income, convert such property within a reasonable time, or exercise the power conferred by § 61-104(a) of this title, as such action or combination of actions are deemed appropriate in the trustee’s discretion.
