Sophie Turner and her ex, Joe Jonas, seem to have things figured out, for now, as pertains to custody of their kids ... which is why she's telling a judge to drop her whole "child abduction" claim from last year.
Per new legal docs, obtained by TMZ, attorneys for the former couple are asking the judge in their federal case out of New York -- which Sophie first filed in September -- to dismiss the entire action ... this in light of the parenting plan they hashed out back in October.
You'll recall ... when she invoked that statute -- claiming, at the time, Joe was preventing their 2 children from traveling to see her across the pond by allegedly withholding their passports -- it elevated that whole matter to a federal level. So, it was on Uncle Sam's radar.
She also claimed they, as a family, had decided England would become their permanent home ... but because Joe was allegedly keeping the kids in NY amid their still-fresh divorce filing, she claimed his actions ran afoul of international child abduction laws.
Since then, of course, she and Joe have landed in a much better place -- yes, their divorce is still proceeding, but they've temporarily worked out who gets the kids and when ... which they're citing here as the reason that this lawsuit she submitted can now go bye-bye.
This just further signals continued efforts by the exes to hash things out privately -- for the sake of their daughters, we assume -- after they kicked off their public split on a particularly bitter foot.
It appears other aspects of the divorce are still being worked out ... but in the meantime, they both seem to have moved on romantically -- Sophie moving on to British aristocrat Peregrine Pearson and Joe to model Stormi Bree.
