By Victoria Cavaliere MORRISTOWN, New Jersey (Reuters) - A New Jersey student who says her parents abandoned her when she turned 18 lost a first round on Tuesday in the lawsuit she filed against them for school costs and living expenses, a case that could set a precedent for a family's obligation to support a child who has left home. A family court judge denied a request by Rachel Canning of Lincoln Park, New Jersey, to have her parents temporarily resume paying her tuition and living expenses. Canning, 18, wants her parents to pay the remaining $5,000 in tuition owed to the Morris Catholic High School, where she is a senior, and she wants access to a college fund that was set up for her. In court, the teen said her parents remain obligated to help her with food, transportation, high school tuition and her college education.
