Wisconsin, like The Revised Uniform Fiduciary Access to Digital Asset Act, establishes of a “three-tier priority system of user direction for disclosure of digital property as follows: 1) an online tool; 2) any other governing instrument (estate planning documents); and 3) the above directions override a contrary provision in a terms-of-service agreement that does not require the user to act affirmatively and distinctly from the user’s assent to the terms of service.” Like beneficiary designations on accounts, make sure that the successor agent on your online accounts match what you intend in your Will or Trust as those online designations will take precedence over what is specified in your Will or Trust.
