Welcome to my world. I'm so sorry you have to deal with this too.

For us, BM works as a nurse but claims she only volunteers so she got input at minimum wage. It's all horseshit. 

Yep. BM2 here works for cash doing eyelashes and also apparently owns 10 rental properties, however they are in her relatives' names and/or she is hiding the income. She drives only luxury cars, goes on fancy vacations, and has purses that cost as much as 5 months of my mortgage. But she's probably getting a raise, too, though she keeps the kids less than half the time and doesn't pay for anything. This system rewards liars and cheats. 

Dear Ladies,

Ah, those many years that my DH paid top dollar in CS while his bone lazy, round-heeled ex-wife worked part-time to better enable her bar/bed hopping! When the children arrived for their week in mid-winter with holes in their ill-fitting boots while  BM sported stylish new footwear, my poor husband would nearly tremble with fury. 

I learned to push the rage from my mind, along with BM’s penchant for shrieking her demands down the phone in a timbre loud enough to get the neighbourhood dogs howling. The very instant that CS ended, The Screamer (our nickname for the bitch) increased her hours to full time. Truly, these women share a book of rules on how to exploit and torment their ex-husbands (and their new wives/partners). All we can do is take deep breaths and uncork the wine.

It is hard baked into the system by mandating CS until age 21 with, in all reality, zero exceptions.

We all know if it was the other way around, they would be imputing Biodad's income like no tomorrow.

In Ontario (Canada) the judges seem to share a dim view of those who are underemployed.  If you can volunteer, you can work.  If you have a degree you SHOULD work.  Unless you can prove physical disability, or the need to be a caregive, you're going to get income imputed.  Even women who get spousal support are starting to be told that (unless you gave up your career to raise children and support his career), you're expected to become self-sufficient in a reasonable amount of time.

At least we seem to be getting that right on average.

Gets child support at 347, and it hasnt been reviewed since we got married (she filed for CS about 2weeks after our wedding), and she somehow gets section 8 housing assistance - she has a 2 bedroom apartment in an expensive area beach town, and who knows what else she gets.

Shes forbidden SD17 powersulk from getting a job so she can keep her low income housing. I wonder what will happen - Im holding my breath for maybe a disabled diagnosis so she can keep that apartment.

BM TT managed to get over 21k for a "head injury" from work, so I know she has it in her to somehow get along in her own way...

No you need better lawyers. 

What is this womans education and work history? I'm sorry but unless she is fully disabled then she should be out working. 

Her income is allegedly $2800 paid by 'others' 

Ma'am with all do respects......shes probably a lady of the night (if ya know what I mean) getting paid in cash and filing not one tax return
