How do you deposit a check that has your name and your ex-husbands name on it but he cant sign it?

To deposit a check with both your name and your ex-husband's name where he cannot sign it, you can consider a few options. If your bank allows, you may be able to endorse the check by writing "For deposit only" followed by your signature. Alternatively, you could ask your ex-husband to provide a signed letter of consent allowing you to deposit the check on his behalf. It's best to check with your bank for their specific policies regarding such situations.
