Custodian transitions can make RIAs anxious about losing clients, but careful planning and strong communication can significantly reduce attrition risk. On average, advisors may lose nearly 20% of client assets during a transition, but that figure often reflects poor preparation rather than an inevitable outcome. 

The key to a successful move lies in two areas: reinforcing client relationships and clearly explaining the reasons and benefits behind the change. Advisors should prioritize transparency without overloading clients with technical details, offering reassurance, a timeline, and emphasizing how the switch enhances service. 

Relationships that feel unstable before a transition may signal deeper issues, making them worth addressing whether or not a move happens. 

Finsum: Ultimately, sticking with a subpar custodian out of fear can hurt more than switching—especially if poor service impacts how clients perceive the advisor’s value.
