Abstract	In the title compound, C17H17N3O3 .0.5H2O, the indazole system makes a dihedral angle of 46.19 (8)° with the plane through the benzene ring and is nearly perpendicular to the allyl group, as indicated by the dihedral angle of 81.2 (3)°. In the crystal, the water mol­ecule, disordered over two sites related by an inversion center, forms O—H⋯N bridges between indazole N atoms of two sulfonamide mol­ecules. It is also connected via N—H⋯O inter­action to the third sulfonamide mol­ecule; however, due to the water mol­ecule disorder, only every second mol­ecule of sulfonamide participates in this inter­action. This missing inter­action results in a slight disorder of the sulfonamide S,O and N atoms which are split over two sites with half occupancy. With the help of C–H⋯O hydrogen bonds, the mol­ecules are further connected into a three-dimensional network.
