We are not aware of anything in Illinois law that would restrict your ability to mail notices to a customer regarding a dormant account. The Uniform Disposition of Unclaimed Property Act imposes an affirmative requirement to attempt to communicate with customers before reporting their property as abandoned. 765 ILCS 1025/11(e) [Repealed effective 1/1/18]. However, nothing in that law would prevent you from mailing notices to customers before those requirements kick in. Other than requirements that may apply under your account agreements, we are not aware of any other restrictions on communicating with customers regarding their accounts when your policies and procedures determine that the accounts are dormant.
