  We consider the nonleptonic B decays $ B \to D^{(*)} D_s(2317)$ and $ B \to
D^{(*)} D_s(2460)$, involving the newly discovered $D_s(2317)$ and the
$D_s(2460)$ states. We find that experiments indicate disagreement with model
calculations of their properties and/or breakdown of the factorization
assumption for these decays . We point out that decays involving $B_s$ mesons
where the $D_s$ resonances can be produced via the weak decay of the $b$ quark
can provide further information about the nature of these newly discovered
states. We also propose a model to calculate the two body nonleptonic decays $
B \to D^{(*)} D_s(2317)(D_s(2460))$, if the $D_s(2317)$ and $D_s(2460)$ are
interpreted as $DK$ and $D^*K$ molecules.
