12 Del. C. § 1183 (2026)

(a) Interest at 0.5% per month on outstanding unpaid amounts accrues from the date the amounts or property were due under this chapter until paid. Interest due in accordance with this subsection may not exceed 50% of the amount required to be paid. Penalties under subsection (b), (c), or (d) of this section are not interest for purposes of this subsection. This subsection applies to any late-filed unclaimed property that is reported and remitted on or after July 1, 2017.

(1), (2) [Repealed.]

(b) If a person fails to file any report required by this chapter on or before the due date prescribed for the report, determined with regard to any extension of time for filing, unless it is shown that such failure is due to reasonable cause and not wilful neglect, the person shall add to the amount of unclaimed property required to be shown on the report the lesser of 5% of the amount thereof if the failure is not for more than 1 month, with an additional 5% for each additional month or fraction thereof during which such failure continues, not to exceed 50% in the aggregate or a civil penalty of $100 for each day the report is withheld or the duty is not performed, but not more than $5,000.

(c) If a person fails to pay the amount of unclaimed property required to be shown on any report required by this chapter on or before the due date prescribed for the payment of such property, determined with regard to any extension of time for payment, unless it is shown that such failure is due to reasonable cause and not wilful neglect, the person shall add to the amount of such property required to be shown on any report 0.5% of the amount of such property if the failure is for not more than 1 month, with an additional 0.5% for each additional month or fraction thereof during which such failure continues, not to exceed 25% in the aggregate. For purposes of this subsection, the amount of property shown on any report is to be reduced by the amount of any property which is paid on or before the beginning of the month for which a calculation is made under this subsection.

(d) If any part of a deficiency in payment of unclaimed property required to be shown on any report is due to fraud, the person must add to the property required to be shown on the report an amount equal to 75% of the portion of the deficiency in payment which is attributable to fraud. The penalty prescribed by this subsection applies only in cases where a report of unclaimed property is filed and only to that part of the deficiency in payment the State Escheator establishes is due to fraud or wilful misrepresentation

(e) If the State Escheator initiates an examination pursuant to information provided by a whistleblower that results in payment from the holder or recovery of property under this chapter, the State Escheator shall award interest and penalties collected under this section to the whistleblower, provided that the whistleblower and any of its agents and counsel have complied with the obligations set forth in the written agreement required by § 1191(a) of this title.
