I'm sorry, but I don't completely understand the question...
If a router has a host route in its routing table, it doesn't need to do any "checking" on that validity of that host router (i.e. neighbor discovery(ND), neighbor unreachability detection, etc.).
However, if a router wants to send a packet to a host on a local link, it will use ND to determine if the host is reachable and get link-layer address information, if needed.
Do either of those statement answer your question?
