In the title compound, C15H12Cl2N2O3, the dihedral angle between the two substituted aromatic rings is 5.4 (4)°. Intramolecular O—H⋯N and N—H⋯O hydrogen bonds affect the planarity of the molcular conformation, with a mean deviation from the plane defined by the non-H atoms of 0.062 (2) Å. The molecule exists in a trans configuration with respect to the methylidene unit. In the crystal, molecules are linked by N—H⋯O interactions.
