I have been seperated for over 2 years divorced less than  six months   we have  5 kids ages from 4 - 16  since seperation ex  has  another child less than a year old

we both love our  kids ...

us on the other hand do not get along at all

Ex  has custody of kids

i work  minimum of 40 hours a week and do other jobs when i can ... ex is a stay at home mom

well here is problem

in the seperation agreement i signed saying there were no existing bills ..   i found out after seperation

There were existing bills i was not aware of ...they have drawn interest  now and are in the 10,000.00 range  or more

also i signed that property was divided 

today it is still in our names 

i want to put property in kids name

she wants it in hers

now i am getting calls daily from creditors 

i am also being garnished  for taxes oowed from years back and on  property ex  lives in and child support,and insurance

child support was set at max they could garnish

i am supposed to pay another 130.00 a month

in which i am behind now

as of now i  clear about 130.00 a week after garnishments

before long i will be in jail for non payment

i try to keep kids every other weekend

it has gotten to point i can't afford to keep them  any longer

these are just a few of the problems there are many more of them
