The father of an accomplished fencer can’t get out of shouldering tournament, equipment and other costs under an agreement he made to pay for all “reasonable extracurricular activities,” a New Jersey appeals court says.

Plaintiff Jayne Valenti and defendant David Bassinder never married but in 1985 had a son. When they ended their relationship in 2008, Bassinder, described as a person of “substantial means” agreed to pay substantially toward the youth’s upbringing.
