Unless your decree (property settlement) provided for maintenance to be adjusted, it can usually not be adjusted unless the party receiving maintenance marries. Look at your decree and see what it says. Your child support has presumably gone down if the older kids have left home. Dividing your income by the number of people in the family is not useful as the cost of maintaining a household is more complex than that and child support is a separate issue than maintenance. When a child leaves home, expenses don't actually go down by the percentage of the people in the household he represents. The mortgage stays the same and most of the utilities change only minimally. Really all that goes down is food and clothing for that child. Check your documents and you'll have the answer to your question.
