Del. Code tit. 10 § 4712
Immediately from and after the minuting and certifying upon the record of the original judgment, or of the testatum fieri facias, as the case may be, of the agreement for the extension of the lien thereof, or the entry of final judgment in the Superior Court in favor of the plaintiff or plaintiffs in the writ of scire facias, or the entry of final judgment in the Supreme Court restoring and continuing such lien, such lien shall continue for the further term of 10 years next thereafter unless sooner lost by final judgment of the Supreme Court. In like manner and with like effect such liens so renewed or restored and continued may, by a like agreement filed, minuted and certified upon the record of such original judgment, or of such testatum fieri facias, as the case may be, before the expiration of the extended term or by final judgment in scire facias, be again renewed or restored and continued for the further term of 10 years, and so from time to time as often as is found necessary.
