In the title compound, C(14)H(10)ClFN(2)OS, the mol-ecule adopts a trans-cis geometry of the thio-urea unit. The dihedral angles between the benzene rings is 34.47 (7)°. The crystal packing features inter-molecular N-H⋯S and C-H⋯O hydrogen bonds, forming a chain along the b axis. A short C-H⋯S intramolecular contact is also observed.
