Interesting CS story.
One of my closest childhood friends and her DH won the lottery ($5mil if I remember correctly). He has a son by a previouse relationship and paid CS.
His winnings paid out annually. He got one check in March of each year for 10 years. ($500,000/Yr)
Each March he had to give his XW $180,000 in a lump sum until his winnings were paid in full. He also had to continue paying $800/mo in CS that was originally set by the court.
Once his winnings were fully paid by the state his CS went back to only the usual ~$800/mo until the kid turned 18.
Once his 10 annual lottery payments stopped, BM lost her house, cars, etc..... Instead of paying cash for these things she had quit her job and financed everything while living on the lottery enhanced CS.
She sued him for continuation of $180K/Yr in CS and lost. Once the lottery commission had paid him in full the courts said the return on his invested lottery winnings were not usable for the calculation of CS because they were not wages.
This goes to show that for many CPs CS is nothing more than an enhancement to the CP's life style and not for the kid(s).
We have received CS for our son (my SS) for 16yrs. We don't need the money but we keep BioDad on the hook so our son (my SS) never has to hear that his "dad" did not give a shit enough to help support him. Though BioDad in fact does not give a shit enough about him to support him. SpermGrandMa and SpermGrandPa have always paid the CS for our kid.
If BioDad won the lottery we would nail his ass to the wall. If we won the lottery .... we would keep nailing his as to the wall. And .... we would use the money to buy some really cool toys, vacations, etc ...... Not on credit of course. We would pay using BioDad's cold hard cash. }:)
