The pair who pleaded guilty to sending abusive tweets to a feminist campaigner are due to be sentenced on January 24 at Westminster Magistrates' Court.
John Nimmo was released on conditional bail while Isabella Sorley was remanded in custody.
District Judge Howard Riddle warned Sorley it was "almost inevitable" that she would receive a jail sentence.
He told Nimmo, described to the court as a "social recluse", that "all options" remained open.
