Amber Harrison is due to find out whether she will have to foot the bill for all of Seven West's legal costs in her court battle over her affair with its boss, Tim Worner.
The former Seven employee has told Justice John Sackar that such an order would be "punitive and pointless" and would drive her into bankruptcy.
The media company had sought a NSW Supreme Court permanent gag order against Ms Harrison preventing her from leaking company documents and details of her affair.
It contended that her social media posts had breached a deed in which the company agreed to pay her $427,418 in instalments for her silence.
On the eve of the hearing, which was due to start on July 10, Ms Harrison abandoned her fight against Seven and agreed to the gag order.
The company then sought other orders, including one requiring Ms Harrison to pay all Seven's legal costs - which could amount to hundreds of thousands of dollars.
In arguing against paying all the costs, Ms Harrison said she was a foster mother and if an order was made it would affect her ability to provide for her family.
"I should not be punished by the court system for taking a stand," she said.
But Seven's lawyer, Andrew Bell SC, said the court proceedings started when she published stolen documents containing confidential legal advice to the Seven board, and that she'd flagrantly breached a deed of release.
"All Seven has done in this case ... is come to court as it is entitled to do, to enforce rights and promises that were made to it in return for substantial sums of money," Mr Bell said.
The judge is due to hand down his decision in Sydney on Monday afternoon.
