I've received child benefit for my 2 kids since they were born and my ex-partner has just submitted an (unexpected) rival claim for both kids (they're teenagers). We've had 50:50 court ordered childcare arrangements for the past few years, but I'm the one who pays for most stuff (clothes, hobbies, school items), and advocates for my kids in education, health and their benefits (one is disabled).
I can't find much info online about rival CB claims other than on Mumsnet, and most people seem to say it doesn't matter what the circumstances are, HMRC are going to award 1 child benefit to each parent.
So I wanted to ask if anyone knows of any examples when HMRC haven't awarded one child benefit to each parent in circumstances similar to mine, when HMRC have acknowledged one parent provides more and so allowed that parent to continue to claim child benefit for both kids?
I'm trying to work out whether it's worth filling out the HMRC forms and saying what I think would be best for the kids, or to just accept the inevitable and save myself a ton of upset and stress.
