Only by polling the PID, which has many problems associated with it.
(The fact that the child has been disowned is not relevant; the answer
is the same either way.)
If you require reliability here, then the parent must take some action
as it is terminating (either by trap EXIT, or by putting commands in
~/.bash_logout), to inform the child.
