DW had full physical and legal custody from birth. The Spermidiot was not listed on the birth certificate as the father though SS had his family name from birth.  DW and the Spermidiot were never married.  DW filed a paternity and CS motion before SS had turned 1yo. That motion upheld full physical and legal for DW, established paternity for the Spermidiot, and ordered $110/mo in CS obligation on the Spermidiot. No visitation was ordered.

The SpermClan filed a custody suit against DW when the small town grapevine informed the SpermGrandHag that DW was dating someone.  DW had left SpermLand for University out of State just after SS turned 1yo. That suit crashed and burned on the SpermClan and full physical and legal was upheld for DW. Visitation was set at 7wks per year of long distance visitation.

After 9 years of $133/mo I was hit in the semiconductor industry implosion and was RIFd.  I pushed DW to file for a CS mod at that point since I had zero income and though the SpermClan would invariably motion for my income to be considered, I had no income to consider.

They went after my income during the custody suit they filed when they learned that DW was dating someone.  We went before the Judge 5days after we married.   The Judge smacked with them clarity that SParent income cannot be considered in CS motions.  

Then.... "StepDad makes a good income and dad should not be punished by having to contribute to an artificially elevated standard of living for the child."  So the idiot Harry Potter robed moron slinging the wooden Fisher-Price toddlers hammer then ruled that the Spermidiot would be granted an income reduction credit for CS calculation purposes.  So, while SParent income cannot be included in CS calculation, it can be used to provide a benefit to POS sum loser derelict wastes of breeder skin in the blended family opposition.

I LOl'd when that was ordered and vocalized to the Spermidiot to enjoy that $50/mo. $50/mo is what the maximum income reduction credit lowered max CS by.  His robed moron Honor did not appreciate my snark.  But, other than bang the toddlers hammer on his desk and order me to be silent there was not much he could do.  After all, he had ruled that I was not a party to the case then could not explain how if I was not a party to the case how could he justify ordering me to provide my income information to him. "Your honor, you have already made it clear that I am not a party to the case, why am I even on the stand?  If I am not a party to the case, neither is my money. So no, I will not provide the court with my income or asset information. After all, I am not a party to the case."  I didn't provide that information for a very long tense period until he threatened me with contempt of court.  At which point I laughed but did not say a word. He had already threatened me with contempt if I said another word. So I crossed my arms gave him a tight lipped fuck off and die smirk and raised my eyebrows at him. so....  He turned purple and ordered me to answer him. To which I kept giving him my eat shit and die tight lipped smirk until he clearly revoked his threat to hold me in contempt if I spoke.  I then tapped my finder an an envelope that I had placed at the corner of the bench when I sat down on the stand when called a half an hour earlier. I then said, I gave it to you 30 minutes ago.  If smoke could come out of someone's ears, it would have been fogging up the court room coming out of the Judge's ears.

The last shot between the Judge and I was when I ran a full page add in the local paper highlighting how the Judge had forced a toddler to spend time with a perve serially arrested for statutory rape with a  bold print "Vote No for Judge XYZLMNOP in the election."  He was standing for re-election in the fall after our late summer hearing.  Our lawyer called us begging me to pull the add. She was terrified that our case would kill her practice in that small town county seat.  The Judge had called her and ripped her a new one after someone at the paper had called the Judge when I placed the full page add.  I refused unless the Judge agreed to recuse himself in any further iterations of our Custody/Visitation/Support actions.  He agreed.

After that, we did run into each other a couple of times over the years when we were visiting my ILs.  There is a great gourmet coffee shop and patisserie on the corner across from the court house that my bride loves. We go there for lunch occasionally and take my MIL and her sister for lunch.   His honor and I have occassionally approached each other on the side walk at which point he turns and crosses the street.  I never threatened him. But neither did I put up with his shit.  

9 years later DW filed for a CS review.  Spermidiot refused delivery of several registered signature required summons notifications and when physically served by the Constable took off running.  All great stuff to bare his ass with during the long delayed CS review hearing.

Because he refused to respond to the DA's subpoena the DA asked DW for income and other information on the Spermidiot. She went CPA on his ass, provided historic tax returns, income information, his employer's contact information, provided the official State and County pay statistics for licensed SpermLand plumbers highlighing recommending that the mid point of that range be used to establish the dipshitiots new CS obligation.  The DA took DW's information, set the new CS at $785/mo up from the 9yrs of &133/mo, and invoked direct payroll withholding.

When he got his first $0.00 pay check Spermidiot came screaming into the court house to demand a hearing.  Unfortunately that was granted rather than him being told to STFU and crawl back under his rock for the 2yr between CS review stipulation.  

During the telephone hearing with the Admin law judge, they did their usual motion to have my income included.  To which we responded with a stack of evidence that the SpermGPs were paying the Spermidiot's CS, paying for the travel costs for SS's SpermLand visitations, that the SpermIdiot was living in the SGP's rental property rent free, and that they were raising his three  younger spawn by two other baby mamas in their home without contribution from the Spermidiot.  They had no way of coungtering our PI reports, and official docs. Then, DW motioned that the SGP's income be added to the Spermidiot's for CS calculations purposes. SpermGrandHag lost her F'n pea brained micro mind.  

The icing on the cake was when the Judge promptly informed them that a SParents income is not considered in setting CS and ..... that she was taking the motion for the SGP's income to be added to the Spermidiot's under consideration.

Her honor was highly impressed with my graduate degreed CPA former single teen mom bride and unline the robed moron in our initial hearing, SpermGrandHag did not clean this Judge's home and office.

Ultimately our motion for the SGP's money was denied but only after a major SpermClan ass chewing by her Honor.  

The DA's setting CS at $785/mo was lowered to $385/mo to go into effect after a full year at $785/mo to compensate DW for the Spermidiot's year of dodging the subpoenas and running from the Constable.

3mos after that hearing, Spermidiot came crying into the court house wanting a CS reduction because he had gotten health insurance on SS as he had been orded to provide 10 years earlier and never provided. Because he did not provide it, even the robed dipshit ordered that his CS be increased to compensate DW for providing health insurance for SS.  Which I provided via my employers.  That cost the SpermGPs $10/mo for 9+years.

We had a quick follow telephone hearing on that where the Judge informed him that the insurance he had provided was sub standard and he would provide both his substandard insurance and continue to pay the additional element of CS to DW to continue to provide quality insurance for SS.  Finally, because he played games with trying to get a modification in far less than 2yrs from the new order without a major change in circumstances, the 2yrs was reset.

Irritatingly, even that wonderful Judge granted the dumbass the maximum income reduction credit due to my income, DW's high income, and due to the Spermidiot adding 3 more out of wedlock spawn by two other baby mamas following the initial hearing where we successfully defended their attempt to take custody of SS 10 years before.

File for the CS modification, go with complete documentation, go loaded for bear, and have fun baring the idiot opposition's ass officially.  You know them, you know what they will likely do, so play them, get them to lose their shit in front of the judge, be confident, and be professional.  Know everything there is to know so if they play games, you can win. And... if necessary, so you can keep the robed moron in their place.  But... don't go too far with that part. I nearly did.

I completely respect the position that a Judge or LEO holds. I do not respect the individual in that role unless they earn it with performance.

That they had to pay CS while DW alone made more than the SpermIdiot and both his parents combined then with my professional income on top drove them nuckin futz.

I cannot imagine the fury associated with being on the quality NCP side of the blended family equation while a toxic CP had control and was paid by my side.   

I hope that your life post CO has been one you enjoy and that your kids have done well.

But they planted their flag on the hill that the pittance in CS ($133/mo) bought our nice homes, top school district for SS, a new car upon occassion, nice vacations, etc...  They attempted to use that to attempt to guilt SS into begging his mom to drop CS all together.  "Your younger sibs do not have the nice things that you have and are starving." 

This among other decade+ manipulations are what ultimately cost them a relationship with my SS.
