Section 498-A in the Indian Penal Code
Section 498-A is a stringent section introduced into the Indian Penal Code, 1860, for punishing a husband or his relatives for harassing a wife with three years' imprisonment and also with a fine if proved.
As per the post, the case filed by the poster's wife is in the trial stage only. Therefore, it is better that the poster should bring it to the notice of the prospective employer with the relevant particulars of the case and the stage of its pendency.
Every accused is innocent until proven guilty. Even the Supreme Court has observed that Section 498-A can be used by any disgruntled wife against her husband as well as his relatives more as a weapon rather than as a shield. Hence, my presumption is that no progressive employer would treat the pendency of a case under Section 498-A against a prospective employee as a disqualification if he promptly disclosed the fact.
