Recently divorced dad of 1 x committed perjury What should I

[firstr]

My X decided to be unfaithful from the time we got married until our recent divorce. I caught her in some of these affairs and because of our daughter and wanting to stay there for the kids (She had 2 from her first marriage) I promised the kids I wouldn’t turn my back on them for any reason and even thru all she has done I still haven’t it’s not the kids fault.
Back in April of this year my x took off with our daughter and her 2 while I was at work sent me a message that said if I wasn’t out in three days I wouldn’t see our daughter again and Ill make sure your out one way or another. I swear on my life I was never violent physical or anything like that I worked and came home she would leave and be gone all night sometimes days at a time.
Anyway When she left I got my stuff and was out in 3 days during my moving out I was hit with divorce papers and a temp custody order also the local Police Dept came over to question me and look around (Embarrassing because I work close with those guys in my line of work) My x had claimed that I had assaulted her and our home was destroyed from the abuse etc. They investigated me I was put on suspension with my job because of it they interviewed her etc long story short she got in trouble for filing a false police report I was found Innocent and returned to work She kept our daughter away from me for six weeks when I had been the primary care giver since day one.
During the divorce process she started acting like she did when she was pregnant with our daughter I told my attorney and nothing was done I found out she was / is pregnant 4 months along now and our divorce has only been final for a month.
I live in Missouri and like most other states perjury is a big no no since there is now proof that she did lie under oath about not being pregnant would I stand a chance at getting full custody because of this?
She now has 3 kids by 3 different men (didn’t know that until we were going thru our divorce) and a 4th on the way by another guy. We currently have full legal and physical joint custody we share equal time (Our daughter isn’t even 2 years old yet)
I really only want what’s best for our daughter and its not her, The X is always dropping her off dirty and in clothes that haven’t been washed in days (or the last time I did them) What should I do?

What to do about perjury?

Nothing will come of it in a legal sense unless you are lying to congress.

Even then........

The time to use someone lying in family court is during an active case to ding the other sides credibility and get the court to see things your way. The fact is that it is assumed everyone lies in family court.

You say she led under oath about being preggo. Can you prove for a fact that at the time she made the claim that she knew it was in fact a lie? Or could she make the case that she just didn't think so at the time? Or any other various shades of "truth"?

Email communacation between her and her family about the reason she wasnt getting prenatel care was because of our pending divorce and she didnt want medical records being sought in court. (thanks to her sister I have those)

IMO, I'd save the perjury for court.

Offer to be free baby sitter and document the time and

The X is always dropping her off dirty and in clothes that haven’t been washed in days (or the last time I did them)

Get her giving 60-70% for a few months and you may have a shot.

Going back to court without giving the court decision long enough to fester is probably best.

I'm sure the false police report is a big part of the 50/50. Having another will help your next case.
