  The definition of accessible coherence is proposed. Through local measurement
on the other subsystem and one way classical communication, a subsystem can
access more coherence than the coherence of its density matrix. Based on the
local accessible coherence, the part that can not be locally accessed is also
studied, which we call it remaining coherence. We study how the bipartite
coherence is distributed by partition for both l1 norm coherence and relative
entropy coherence, and the expressions for local accessible coherence and
remaining coherence are derived. we also study some examples to illustrate the
distribution.
