i am from georgia. i have been divorced since 1993. i have two children. i am currently getting $700 every four weeks based on their dad's salary of app. $32,000 in 1993. i have never asked for an increase in child support. i want to know what the percentage is that is allowed and reasonable for two children. his current salary is a base of $45,000. i suggested 25% of the sum of his current salary and the average of his last three years' bonuses. i would also like to know if there is a way to amend the current agreement without hiring a lawyer. what do you say?
