25 Del. C. § 730

If it appears to the commissioners that partition of the lands mentioned in the petition for partition can be made among the primary interests and that a partition of the lands among all persons entitled would be detrimental to such persons, the commissioners shall make a return, with an allotment, accordingly, and shall also appraise the value of all of the lands in money. At any time after such a return of the commissioners and before final decree, any joint tenants, tenants in common or parceners representing an entire primary interest so allotted may apply to the Court to have the share or part of the lands, found by the return to belong to the primary interest, allotted to the persons entitled to the primary interest in kind, to hold to them in severalty or as tenants in common or as joint tenants or parceners as the case may be. In such case the Court may make an allotment of the primary interest concerned in the application, order a sale of the residue of the lands, and make distribution of the proceeds thereof, in accordance with this chapter.
