In a court transcript, Stephanie Hallowich says the couple agreed to the $750,000 settlement "because we needed to get the children out of there for their health and safety".
"We know we're signing for silence forever, but how is this taking away our children's rights, being minors now?" she asks, referring to her then seven-year-old daughter and 10-year-old son.
The family's attorney, Peter Villari, appears equally baffled, saying that in his 30-year career he's never seen such an order apply to minors.
Chris Hallowich argues that the two children will be growing up in the heart of the major US fracking region, with other children whose parents work in the industry.
"We can inform them. We can tell them they cannot say this, they cannot say that, but if on the playground --."
James Swetz, the lawyer for Range Resources Corporation, one of the two defendants, insists it is part of the deal.
"I guess our position is that it does apply to the whole family. We would certainly enforce it," he said.
