A joint tax return requires that both of the people sign the return. If the return was mailed, then you were supposed to use a pen and sign it yourself. So he might have forged your signature if he printed and mailed it. Or if he e-filed, he "signed" it electronically, but that was still your "electronic signature" on the return. You are legally responsible for what that return said. If he falsified any information on those returns, you will have a problem.
Again--get a free transcript of your return(s) from the IRS so you can see what was on them. You can use your own Social Security number to get the transcripts.
