Thru the calculations I have worked today - it appears that the monthly amount would change by about 30%...worth fighting for Definitely! NEXT question - how can I make this retroactive to the point where he began making double the salary??? He's given a company truck each year & has an expense account for all his personal needs-food, clothing, gas etc.(everything but paying for his house) - it seems that this too would/should be added into his income also, yes??? Please let me know if anyone out there has any knowledge of modifying something like this - it would mean so much for my daughter (especially since he has yet to agree to pay for her college tuition or give her back the savings account we started for her) Thank you very much for your help!
