BM possibly moving... thoughts?
I wanted to get everyone's opinion on here... but here is some back story first.
In 2015, DH was granted from a judge that he could move to this state and have SD full time, with BM having visitation in the summers and holidays. At the time she was 8 hours away in another state. BM shot herself in the foot by commiting perjury. This is how DH basically got a "free pass" to move with SD.
BM moved to our town, finished school, got a job, filed to modify custody after establishing residency here. We went to 50/50 in 2018. BM has medical decision "tie-break" and DH has educational "tie-breaker" This includes choosing schools that SD attends.
Fast forward to 2020... SD is now 10. She prefers BMs house because there are NO rules. BM has a new boyfriend this year that lives about an hour away (another county/city). DH is worried that when SD gets older, she will "have a say" in which parent she wants to live with. I looked it up and it seems (in our state anyway) there is no magic age, but a judge might take a child's testimony into consideration. He thinks BM will try to move SD to this new town so she can be closer to her BF and take DH back to court. We have seen text messages of BM sending SD house listings. SD has mentioned that BM wants to get a house (didn't say where though, BM is still renting an apartment currently).
So here is the kicker, with DH having final say for educational decisions, he gets to decide (currently) where SD attends school. What are the chances a judge would grant BM majority custody, permission to move, and take away DH educational tie-breaker, and BM can decide on schools? Also, we live is a fairly liberal major city (very friendly to dads). So if DH hasn't done anything wrong (abuse, drugs, endangerment, etc.) would he get his custody time reduced?
TIA for your thoughts and experiences!
