In the title compound, C(14)H(14)N(2)O(2)S, the dihedral angles between the thio-urea group and the methoxyphenyl and hydroxyphenyl rings are 61.91 (4) and 76.90 (4)°, respectively. The benzene rings are twisted with respect to each other, making a dihedral angle of 71.03 (4)°. The H atoms of the thio-urea NH groups are positioned anti to each other. In the crystal, inter-molecular N-H⋯S, N-H⋯O and O-H⋯S hydrogen bonds link the mol-ecules into a three-dimensional network.
