Del. Code tit. 12 § 3543
If the terms of a will or a writing creating a trust, including, but not limited to an inter vivos trust agreement, provide for the establishment of a trust all the assets of which, due to the circumstances existing at the time the trust is to be established, are required to be distributed to the trust's beneficiary or beneficiaries immediately, the executor, trustee, or other party having possession of the property with which such trust will be established, is authorized to make direct distribution to the beneficiary or beneficiaries of the trust, rather than to the trustee, without the necessity of a Court petition. The receipts of such beneficiaries shall protect the executor, trustee, or other party having possession of the property with which such trust would be established, to the same extent as the receipt of the trustee.
