It's not going to affect the case too much, in my opinion. The custody issues are being decided in late February-early March 2024, and the Elkins Kalt firm's involvement will then cease, since they are being retained solely for custody issues at this time. (The Langlois firm is retained for the financial issues, and they're not going anywhere.) Another partner at the firm will simply take over the case. In law firms, the more junior attorney does the majority of the work, so Katherine Herseema can take the case from here under a partner's supervision. Who knows, the new partner may not be as lenient on Alice as Anne Kiley has been.
Apologies if this has already been said, I've not caught up yet.
