Does a dependent wife has any right over the money received from filing taxes?What can she do if the husband isn't willing to give that money when married filing jointly?

A spouse is never a dependent.

If two spouses file a joint return, they must both sign that they agree to file jointly.

Can you explain your situation in more depth?

I guess he filed it jointly but without my signature! So could there be a way around for him without getting my signature?

Talk to a lawyer.

Ok thank you

Your question is really about legal remedies for a spouse who filed a joint return without your consent, and for that, we have to refer you to a lawyer.

Could you refer me to one? I live in California

No.  If you are having marital problems, the matter of selecting an attorney is very personal.  Check with friends or relatives who might have used attorneys in the past.

Ok

In most localities, there are free consultations offered with local attorneys through Legal Aid.  You might wan to start there.

Ok thank you
