My husband has two children from a previous marriage and pays child support. In the last five years several events have occurred: we have had two children, I was let go from my job, and the ex now has her own company securing government contracts. The income disparity between she and my husband has grown considerably. The oldest child is about to turn 18 and it is time for a reduction. Will the fact that we have two children and I am out of work have any effect on how the reduction is calculated?

In some states yes and in some states no. So depending on where your at the other children might figure into the support as a whole. As far as being 18 again some states require it to run until 21.

We are in Maryland and they don't require past age 18; in addition my husband agreed to paying for college.

In the online worksheet there are no exceptions for children outside of those involved in the child support calculation. So him having gone on and having more children has no effect as to the amount. As far as her making more money at this time that will be entered into the calculation and from there it could cause some kind of a reduction. But for the child leaving the child support rolls is an automatic reduction in itself.

Does it say in court papers he's going to pay for college? Are there dollar amounts or GPA's that go with it? If not he may find himself getting an increase instead.

That is good because in some cases it can go on forever.
