This paper obtains dark and singular 1-soliton solutions in dual-core fibers by the aid of G'/G-expansion scheme. The constraint conditions, for the existence of the soliton solutions, are listed. Additionally, a couple of other solutions known as singular periodic solutions, fall out as a by-product of this scheme. This scheme however fails to retrieve bright soliton solutions.
