BM's other son WAS considered in previous CS obligations... but no deviation for her is granted in WA, as she is the CP. She can deviate all she likes by adjusting what she spends on the kids.
We too have an income shares model, but there is no MORE support to be had when a deviation happens there is LESS support overall and only on the NCP side.
It goes like this:
Get BM & BF's incomes
withhold taxes and Soc Sec and stuff to get Net monthly income
(if BM gets the exemption it is added to her income and vice versa)
add both net incomes together
How many kids and what age for these two parents TOGETHER
look at table for guideline for each and **add together
divide by each parent's income to get their share
set each parent's percentage
Multiply percent by guideline amount to get baseline support amount.
calculate unreimbursed medical (include costs for premiums here too)
Note any credit for which parent pays premiums, copays etc.
split by each parents' percent
Calculate long distance visitation costs
Note any credit for which parent pays
split by each parents' percent
Calculate necessary child care expenses
Note any credit for which parent pays
split by each parents' percent
Add the baseline support, Medical, Transportation, and Childcare expenses together. That is the total support.
Now add all credits for the 3 areas
Take the sum from their respective sides (since it is already paid directly)
Now you have the NCP's ordered amount on his/her side
---- BUT WAIT!
then it must CHECK:
Find the poverty level for one person - Notate that
Bring your Net income from page one - Notate that
Subtract ordered amount - get the sum
Divide net income by 45% (or if there is arears 55%) - Notate that
Determine if taking the CS puts an NCP below poverty level for one person if so, deviation from guideline is nearly automatic.
Determine if ordered amount is over the percent of income allowed.
If it has not impoverished the NCP, then you move on.
Now you run the numbers again -- with the the NCP side accounting for all children to whom he owes a duty of support
(EXAMPLE: Look in the table for 3 children, with
SS at an age above 12)
get that amount for SS
now run from ** above again.
Run the checks
take the second instance from the first instance.
That number is what the deviation amount is and is SUBTRACTED from the NCP obligation. BM's calculations remain static ON PAPER.
5% of unreimbursed medical is built into the guideline in WA
NCP owes when CP's proves that credited amounts have been exceeded.
(EXAMPLE: $31 for medical is both built in and includes BM's percentage of premiums paid by
DH. -- she must use all of the already paid $372/yr on unreimbursed medical before she can come for ANY more from DH.)
In my state, there is simply LESS $$ in the CP home if a deviation from guideline is granted. Deviation is not a percentage, but a SET amount of money that the NCP is then not obligated to pay. Deviation from guideline for DH who has 2 other children is not even HALF of SS' CS total support amount... so EQUAL is not possible. FAIR is that DS1 and DS2 are considered and taken into account. Could we raise DS1 and DS2 on $156 a month? NO. It is RELIEF, not RESOLUTION.
It appears WA guidelines are slightly better than your state, but not by much. You've convinced me, I agree, your state is messed up.
