As mentioned below, your TIC Agreement should cover what happens in that case. That said, these agreements can sometimes be somewhat vague depending on who wrote them, and enforcing an agreement can be time-consuming and expensive if the other co-tenant(s) don't want to play ball.
If it isn't clearly spelled out in your TICA talk with an attorney who specializes in this area of law. We use Lyssa Paul - firstname.lastname@example.org
She seems to be the best of the ones we have dealt with.
