What happens in a Delaware unclaimed property audit?

The short answer
The State Escheator examines the holder's records to determine compliance under 12 Del. C. section 1171, almost always through an outside audit firm retained by the state, and commonly with a group of other states joined to the same examination. The defining features are duration and reach: examinations routinely run three to seven years, and the statute permits enforcement for 10 years after the duty to report arose, with the examination tolling that period once it begins. The financial center of gravity is estimation. Where the holder has not retained the records section 1145 requires for the lookback years, section 1176(a) authorizes the State Escheator to determine the amount due using a reasonable method of estimation, including extrapolation and statistical sampling, and because estimated property has no owner address, it defaults under the second priority rule to the state of incorporation, which is Delaware for a large share of the companies being examined. Interest accrues at one half percent per month on unpaid amounts, capped at 50 percent of the amount due, under section 1183(a). Two structural protections matter as much as the exposure. Delaware cannot open a new examination without first inviting the holder into the Secretary of State's voluntary disclosure program, subject to narrow exceptions, so an audit notice almost never arrives without a declined or ignored invitation behind it. And the whole framework, the 10-year lookback in section 1156, the 10-year record retention rule in section 1145, and the estimation regulations required by section 1176(b), exists because a federal court held the state's prior practices unconstitutional; the statute is a settlement with the Due Process Clause, and its limits are enforceable ones.
How the examination arrives and who conducts it
Under section 1172(a), the State Escheator may not initiate a new examination unless the Secretary of State has first notified the holder in writing of the opportunity to enter a voluntary disclosure agreement, or the holder has failed to comply with the program's requirements, with limited exceptions enumerated in section 1172(d). The practical sequence is therefore invitation first, examination second; a separate article in this library covers the invitation letter and its 90-day clock. Once an examination opens, the day-to-day work is performed by third-party audit firms under contract with the state, frequently compensated in whole or in part on a contingent basis, and the engagement letter typically discloses a roster of additional states participating in the same examination, ten to fifteen being unremarkable. Each participating state's claim rides on its own priority-rule entitlement, which means the address analysis is being run for the whole group at once.
The document requests track the property, not the tax returns: outstanding and void check registers for payables and payroll, bank reconciliations, credit agings and unapplied cash, write-off and miscellaneous income activity, gift card and suspense detail, chart of accounts, and the policies and procedures that governed all of it, for every year in the lookback. Section 1145 requires holders to retain the supporting records for 10 years after the report was filed or was due, which is precisely the period the examination will test.
Estimation, and the case that disciplined it
Estimation is where examinations of long-time nonfilers are decided. For years where records exist, the examination identifies actual items and actual owners. For years where they do not, section 1176(a) permits a reasonable estimate built from the years that can be tested: the examiner derives an error or escheat rate from the reviewed periods and extrapolates it across the missing ones. Because the extrapolated liability is by construction addressless, it flows to Delaware as the state of incorporation, and no other state's exemptions apply to it. That mechanism is lawful today because it operates inside limits that did not always exist. In Temple-Inland, Inc. v. Cook (D. Del. 2016), the federal district court reviewed an examination that combined a lookback of more than two decades, no obligation to have retained records for that span, and an extrapolated demand for property that in significant part had likely been owed to other states or already paid, and held that the combination violated substantive due process, characterizing the state's course of conduct as shocking the conscience. The case settled after the ruling, and the General Assembly rebuilt the statute in 2017: the 10-year enforcement limitation of section 1156, the matching record retention period of section 1145, and the requirement in section 1176(b) that the Secretary of Finance, in consultation with the Secretary of State, adopt regulations governing estimation methodology, base periods, exclusions, and what counts as complete records. An examined holder should read the estimate against those regulations line by line, because base-period selection, outlier exclusion, and the definition of researchable items each move the number materially.
Interest, penalties, and the newest pressure point
Interest accrues at one half percent per month from the date the amounts were due, capped at 50 percent of the amount required to be paid, under section 1183(a); penalty provisions sit in sections 1183 and 1184. The voluntary disclosure path exists in large part because it resolves with interest and penalty relief that an examination does not offer. The 2024 legislation known as Senate Substitute 1 for Senate Bill 266 added a further asymmetry: it created a formal whistleblower framework for unclaimed property noncompliance, with percentage awards for informants, and, in what is now 12 Del. C. section 1185, it bars the State Escheator from waiving interest and penalties in examinations initiated by whistleblower information. The same section sets interest floors for ordinary examinations noticed after August 1, 2021, so even outside the whistleblower context, waiver inside an examination is partial at best. A holder whose noncompliance is reported rather than self-disclosed therefore loses the waiver even as leverage.
One development from outside Delaware is worth holding onto for examinations that drag. In Dine Brands Global, Inc. v. Eubanks (Michigan Supreme Court, March 24, 2025), the court held that an unclaimed property examination is a proceeding within Michigan's limitation statute but that commencing one does not toll the period, which the legislature had not provided for; the question whether a post-examination demand starts a fresh obligation was remanded and remains open. Delaware's own statute tolls its 10-year period during an examination, so the holding does not transfer directly, but the decision signals that courts are willing to hold unclaimed property enforcement to the literal text of limitation statutes, and multistate examinations now proceed with that possibility in the room.
Practice notes
The moment an examination notice arrives, the voluntary disclosure door is closed for the entities and periods it covers, so the defensive work happens inside the examination's own rules: confirm every participating state and its priority-rule basis, test the proposed base period and sampling plan against the estimation regulations before agreeing to it, insist that items researchable to an address leave the estimate and go to their first-priority state with that state's exemptions applied, and manage the record production so that the years with good records do the talking. Duration is a cost decision as much as a legal one; three to seven years of professional fees and management attention belong in the same analysis as the assessment itself. And for the Delaware-incorporated company that has not yet received anything: the record retention clock and the address hygiene that keep property out of the second-priority default are the cheapest defense available, and they only work if they start before the letter comes.
