State District Judge Dale Tillery did not immediately rule Friday on whether a Texas statute of limitations prevents Jana Weckerly's lawsuit from proceeding.
Weckerly's lawyer, Thomas Bowers, argued Jones paid her hush money for at least four years after the alleged 2009 assault, creating a conspiracy to silence her.
But Levi McCathern, one of Jones' lawyers, denied any payments were made and said even if they were, Weckerly wasn't under any pressure to take them.
Jones has also denied the allegations of assault.
The next hearing in the case is scheduled for Oct. 16. Weckerly is seeking damages of more than US$1 million.
