Ex wife avoiding paying back taxes
I've been divorced since 2010 from her, she has since moved from Louisiana to Florida with my 12 year old daughter (I agreed to the relocation because all I want is for my daughter to be happy, now I'm regretting it!). I've been informed that my ex wife has "flags" on her drivers license and it's been expired since 2011. So, she is driving our daughter around with an expired DL as far as I know. Now this is where it gets strange, last night my son (21 years old) told me she in fact did have a Fla. DL, but, I was told by the DMV in La. That she couldn't get one because the "flags" are nationwide. I've known my ex to lie and cheat, scam, etc. in the past so I wouldn't put it past her to have purchased a fake Fla. DL.
Recently, I made her take a drug screen in Fla. Which I paid for, the results came back negative but the name of the person that took the test is not her new married name nor her old married name. That kind of puts a red flag up for me but my attorney at the time (fired her) didn't seem to care. My question is, why would she use her birth given middle name (which has been dropped for my last name) and my last name as the ID at the drug screening facility? I did a "people search" for her new married name and nothing comes up, like she never existed. Could she have changed her name, stolen someone's identity, or does she just have many aliases with ID's for each?
Together we owed taxes from before our marriage, I'm paying them but she doesn't and doesn't seem worried about it (she was ordered to pay half the tax debt). So, can I pro se, file a motion for discovery with her attorney to find out what's going on, like for a copy of her DL, a copy of the ID she used to take the drug screen, a copy of her last tax filling? If so, how do I write (word) it?
