Unclaimed property due diligence: the owner letters holders must send
Before a business reports unclaimed property to the state, most states require it to write to the owner one last time; this is the due diligence letter.7 Timing and thresholds differ by state: Michigan, for example, requires the letter 60 to 365 days before the report for property of $50 or more,3 Kansas 60 to 120 days for items over $100.1
On this page
- The letter is a last attempt to reach the owner before the property goes to the state.7
- The common window is 60 to 120 days before the report, as in Delaware, Louisiana and New Mexico,111522 but Michigan allows up to 365 days3 and Connecticut uses fixed dates, July 1 to September 30.10
- Most states listed here require letters for property of $50 or more; Alaska, Maryland, Minnesota and Virginia use $100,6171831 while Guam and North Dakota go down to $25.1323
- Some states require certified mail for large amounts: Florida a second, certified notice for property over $1,000,12 and Ohio certified mail instead of first-class mail at $1,000 or more.24
- A letter that is not returned does not count as contact with the owner in Michigan,3 and a returned letter does not count in Connecticut.10
Due diligence is the step between finding a dormant account on your books and sending it to the state. Under most state laws, a holder that has a usable address for the owner must write to the owner first, within a set window before the report, and give them a chance to keep the property.13 Arkansas’s Auditor of State describes it as the last attempt to reunite the property with its owner before escheatment.7

When the letter must go out, state by state
These are the rules in the states listed below, from official sources. “Before the report” means before the holder files its annual report, unless the row says otherwise. For report due dates, see the reporting deadlines table.

| West Virginia | 60 to 120 days before the report32 | $50 or more32 |
| Wyoming | Not more than 120 days before the report33 | $50 or more33 |
Some states word the rule differently in different official sources. Utah’s statute says 60 to 180 days,30 while its administrative rule says between 60 days and one year before reporting.36 Michigan’s FAQ says due diligence applies when the property is “over $50”,2 while its 2026 holder manual says “$50 or more”.3
Many of the statutes above also say the letter is needed only when the holder has an address that its records do not show to be wrong, and when the owner’s claim is not time-barred.52225
Michigan due diligence letters
Michigan’s Treasury manual requires written notice to the owner’s last known address when three conditions are met: the address appears to be accurate, the property is $50 or more, and the statute of limitations does not bar the owner’s claim.3 The letter must:
- tell the owner the property will be transferred to the state if they do not respond;3
- give a deadline for contacting the holder to stop the property from being reported;3
- be sent no less than 60 and no more than 365 days before the report is filed.3
Michigan’s report is due on the first business day of July, for property that reached its dormancy period by March 31.4 Treasury’s recommended timeline puts the letters on or before April 15.4 The manual also says that a letter not coming back from the post office does not, by itself, count as contact with the owner or activity on the account.3 Sample letters are in Appendix C of the manual.3
What the letter must say
Several states write the heading into law. Delaware’s letter must open with: “Notice. The State of Delaware requires us to notify you that your property will be transferred to the custody of the State Escheator if you do not contact us before [insert date that is 30 days after the date of this notice.]”.11 Utah’s statute has a similar heading with its own wording.30
In other states the content is set in general terms. Michigan asks for the transfer warning and a response deadline.3 California’s law asks holders to tell the owner that the property will escheat to the state.9 Each state page links its program’s holder pages.
How the letter is sent
The statutes usually call for first-class mail, as in Delaware and Maryland.1117 Some states add email or certified mail:
- Email. In Connecticut, a holder whose owner agreed to electronic notices must also email the owner, whatever the amount.10 California allows electronic notice when the owner consented.9
- Certified mail. Florida requires a second notice by certified mail, return receipt requested, for property over $1,000.12 Ohio requires certified mail for its OUF-8 notice when the amount is $1,000 or more.24
What counts as contact with the owner
Connecticut says that if the owner contacts the holder by phone, email, letter or in person, that is contact and the property should not be presumed abandoned.10 Returned mail and silence are treated differently. Connecticut also says a letter returned as undeliverable is not contact, and the property must be reported.10 Michigan says a letter that is not returned does not, by itself, count as contact either.3
Costs, penalties and records
- Costs. Pennsylvania forbids charging the owner any cost or fee for the notice.26 Florida lets the holder deduct the certified-mail postage from the property as a service charge,12 and Ohio allows up to $20 for mailing costs on certified notices.24
- Penalties. In Kansas, willfully failing to send the notice carries a civil penalty of up to $5 for each owner not notified.34 Iowa’s Treasurer may charge a holder that did not do due diligence on time $5 for each account reported, if 35% or more of the accounts are claimed within 24 months after the report is filed.14 Connecticut does not grant reporting extensions to holders that failed to complete due diligence.10
- Records. Ohio requires holders to keep records for five years beyond the dormancy period, including the signed, returned OUF-8 notices.35
These are the rules as each state publishes them. They are not legal advice; each state’s own law and its unclaimed property office decide how they apply to a particular holder.
Next step
Find each owner’s state with the which-state tool and check the dormancy table. If you have nothing to report, see negative reports; if earlier reports were missed, see voluntary disclosure. To see these notices from the owner’s side, read why you got a letter.
Questions people ask
What is an unclaimed property due diligence letter?
It is the written notice a holder sends to the owner at the last known address before reporting the property to the state, saying the holder has property that will be turned over unless the owner responds.13 The Arkansas Auditor of State calls it the last attempt to reunite the property with its owner before escheatment.7
What is the Michigan due diligence letter requirement?
Michigan's Treasury manual requires written notice when the owner's address appears accurate, the property is $50 or more and the claim is not barred; the letter must be sent 60 to 365 days before the report and give the owner a deadline to respond.3 Treasury's recommended timeline says to mail letters by April 15 for the report due the first business day of July.4
When do due diligence letters have to be sent?
It depends on the state of the owner's address. Many states use 60 to 120 days before the report, such as Delaware and West Virginia;1132 Florida uses 90 to 180 days,12 Maine and Utah 60 to 180 days,1630 and Connecticut July 1 to September 30.10
Is there a minimum amount for due diligence?
Usually yes. Most states listed here set $50,51112 others $100617 or $25.1323 Connecticut requires email notice for any amount when the owner agreed to electronic notices.10
Can a business charge the owner for the letter?
Rules differ. Pennsylvania forbids any cost or fee to the owner for the notice.26 Florida lets the holder deduct the postage for its certified-mail notice as a service charge,12 and Ohio allows up to $20 for mailing costs on certified notices.24

Such due diligence notice must be sent to owners between July 1st and September 30th of the calendar year in which the presumption of abandonment is to take effect.
In addition, regardless of the properties value, if a holder has received consent to the electronic delivery of any notices required by law, due diligence must be sent by electronic mail directed to the owner’s last-known electronic mail address.
Due diligence sent by first class mail is only required if the cumulative value of the owner’s property is $50 or more. Due diligence through electronic mail is to be performed on all properties irrespective of dollar amount.
If the owner contacts the holder via phone conversation, email, letter, or in person, this is considered contact and the property should not be presumed abandoned.
If the due diligence letter is returned by the post office as undeliverable, this is not “contact” with the owner and the property is subject to reporting and remittance by the holder.
An extension will NOT be granted to companies who failed to complete due diligence requirements, as set forth in state law.
