Currently, there is pending legislation to equalize the issue of child support for students who elect to attend a service academy in NYS. "This bill would rectify a situation in which a child under the age of twenty-one who enters a particular class of secondary school, such as preparatory schools or military academies may be considered legally emancipated and thus ineligible for child support from the non-custodial parent, despite the custodial parent's continuing obligation to support the child that continues, in fact, to be an unemancipated dependent. This bill would provide for the continued payment of child support in such situations." If you are a NYS resident, and have a child who is currently in an academy or hopes to attend one in the future, you might want to take a look at this bill and contact your state senator about it.
