I've been separated from my ex since Sept 2015. We're still not technically divorced and no taxes were filed for 2015 or 2016. I have the information I need to file our taxes jointly, but do I need her explicit consent to do so? There is no current order stating how we should file. If I do file, I understand I'd need to provide her with half of the return. If there is something missing or unreported with the taxes on her side, who becomes liable? Are we equally liable?
