Del. Code Ann. tit. 6, § 18-106
(e) Any act or transaction that may be taken by or in respect of a limited liability company under this chapter or a limited liability company agreement, including, in either case, any act or transaction by any member, manager, or other person, whether the member, manager or other person is acting in the member’s, manager’s, or other person’s individual capacity or on behalf of the limited liability company, but that is void or voidable when taken, may be ratified (or the failure to comply with any requirements of the limited liability company agreement making such act or transaction void or voidable may be waived) by the members, managers, or other persons whose approval would be required under the limited liability company agreement:
Any such ratification or waiver may be express or implied, including by the statements, action, inaction, or acquiescence of or by such members, managers, or other persons. If the void or voidable act or transaction was the issuance or assignment of any limited liability company interests, the limited liability company interests purportedly issued or assigned shall be deemed not to have been issued or assigned for purposes of determining whether the void or voidable act or transaction was ratified or waived pursuant to this subsection. Any act or transaction ratified, or with respect to which the failure to comply with any requirements of the limited liability company agreement is waived, pursuant to this subsection shall be deemed validly taken at the time of such act or transaction. If an amendment to the limited liability company agreement to permit any such act or transaction to be validly taken would require notice to any members, managers, or other persons under the limited liability company agreement and the ratification or waiver of such act or transaction is effectuated pursuant to this subsection by the members, managers, or other persons whose approval would be required to amend the limited liability company agreement, notice of such ratification or waiver shall be given following such ratification or waiver to the members, managers, or other persons who would have been entitled to notice of such an amendment and who have not otherwise received notice of, or participated in, such ratification or waiver; provided that the giving of the notice is not a condition to the effectiveness of such ratification or waiver. The provisions of this subsection shall not be construed to limit the accomplishment of a ratification or waiver of a void or voidable act by other means permitted by law. Upon application of the limited liability company, any member, any manager or any person claiming to be substantially and adversely affected by a ratification or waiver pursuant to this subsection (excluding any harm that would have resulted if such act or transaction had been valid when taken), the Court of Chancery may hear and determine the validity and effectiveness of the ratification of, or waiver with respect to, any void or voidable act or transaction effectuated pursuant to this subsection, and in any such application, the limited liability company shall be named as a party and service of the application upon the registered agent of the limited liability company shall be deemed to be service upon the limited liability company, and no other party need be joined in order for the Court to adjudicate the validity and effectiveness of the ratification or waiver, and the Court may make such order respecting further or other notice of such application as it deems proper under these circumstances; provided, that nothing herein limits or affects the right to serve process in any other manner now or hereafter provided by law, and this sentence is an extension of and not a limitation upon the right otherwise existing of service of legal process upon nonresidents.
