[Amended effective December 1, 2018; January 1, 2022.]
Plain-English Summary
The longest rule in the opening chapters, because getting notice to the right person is where cases most often go wrong.
Issuing. On commencement, the Clerk issues the summons and delivers it with a copy of the petition to the sheriff of the county specified, or to a person the court specially appoints. The summons bears its date of issuance, the Clerk's signature and the court's seal, names the court and the parties, names the person it is directed to, gives the petitioner's attorney's name and address (or the petitioner's own), and states the time within which the respondent must appear.
Who serves. The sheriff, a sheriff's deputy, a deputy designated and sworn by the Chief Judge, or a person the court specially appoints. A subpoena is the exception and goes by Rule 45.
How, on whom. The summons and petition are served together. On an ordinary adult, by handing it over, by leaving it at the dwelling with someone of suitable age and discretion residing there, or by delivering it to an authorised agent. On a child under 18 or an incompetent person, through the parent, custodian, guardian or trustee in this State — and if there is none, in the same manner as on an individual. Where a statute or order prescribes a different method, including publication in print or on the court's legal notices website, that method controls.
Return. The summons is returnable 20 days after issuance unless the court orders otherwise, and the server must return it promptly and in any event on the return day. Process that could not be served is still returned, with the reason.
Afterwards. The court may allow process or a proof of service to be amended unless doing so would materially prejudice the substantial rights of the party served. And once a party or attorney has been served or appeared, notice of a hearing may be given in court, by ordinary first-class mail to the last known address, personally, or in any other reasonable manner the court directs.
Frequently Asked Questions
How is a Delaware Family Court summons served?
By the sheriff, a sheriff's deputy, a deputy designated and sworn by the Chief Judge, or a person specially appointed by the court. A subpoena may instead be served as Rule 45 provides.
How long is a summons good for?
It is returnable 20 days after issuance unless the court specially orders otherwise.
How do you serve someone who cannot be found?
Where a statute, rule or order provides another method for the action, that method controls — including service by publication in print or on the court's legal notices website.
How is a child or an incompetent person served?
Through a parent, custodian, guardian or trustee in this State, served in the same manner as an individual or a corporation as the case may be; if there is none, service is made as upon an individual.
Can a mistake in the paperwork be fixed?
The court may allow process or a proof of service to be amended at any time, on terms it thinks just, unless it clearly appears that material prejudice would result to the substantial rights of the party against whom the process issued.
