Anatomy of a Due Diligence Letter

May 14, 2021

What is unclaimed property due diligence?

An unclaimed property due diligence letter is an organization’s last chance at contacting an apparent owner and preventing their property from escheatment. Each state or reporting jurisdiction has its own unique set of requirements and standards. Due diligence letters are typically required to be sent 30 to 120 days before the report date and include a header warning, unique identifier and property amount, deadline to take action, post-escheat statement, owner disposition options, change of address form, owner verification requirements and holder contact information.

Because unclaimed property due diligence processes vary both by state and property type, creating and maintaining an effective management process isn’t easy.

There are currently 55 escheat reporting jurisdictions and more than 100 types of unclaimed property that require letters including uncashed vendor and payroll checks, escrow balances, accounts receivable credit balances, overpayments, unidentified remittances, unredeemed gift cards, rebates, health and welfare plans, self-insured benefit plan payments, stocks, bonds and dividends.

Don’t wait until mailings are due

Most states require companies to perform owner outreach efforts to property owners after the dormancy period has elapsed – usually three to five years after the payment or credit was originally generated. At this point, due diligence letters are simply notifications mailed to owners informing them that their property is in danger of being escheated to the state of last known residence.

However, by performing owner outreach efforts or research early in the process (for example, when checks have been outstanding for six months) you are better positioned to locate property owners and reunite them with their funds. As a result, less dormant property is generated and helps you save money on both returned mail and servicing inactive accounts and property. Pair your due diligence with outbound phone calls or emails for even greater effectiveness.
