Del. Code tit. 6, § 7715

Any settlement of the dispute submitted to ADR shall be reduced to writing as soon as possible after the settlement is reached, with such writing to be prepared by the ADR Specialist (unless the parties otherwise agree as part of their settlement that they will prepare the writing) and shall be signed by the parties to be valid and binding upon them. If no settlement is reached at the close of business on the day the ADR is commenced or after further mediation at the parties request until an impasse is declared, the ADR Specialist shall declare the ADR has concluded by advising the parties in writing.
