Is the husband obligated to pay the driver's and maid's wages for his working wife, knowing that he spends on her and covers the household expenses? And is his refusal considered a dereliction of her marital rights?

We advise seeking wisdom and consulting with sensible people to resolve the problem. If she oversteps her bounds with you, raises her voice, or disobeys you, then she is disobedient (nashiz), and you should follow the steps for addressing disobedience (nushooz) with her. You have the right to prevent her from working if that was not stipulated in the marriage contract.
