I see, thank you for the additional information. It appears that there is a new custody action pending and a request has been made to the court to enter an Order regarding custody. It would be highly irregular for a court to enter an ex parte Order for sole custody without a full evidentiary hearing and this is probably what the hearing on October 13th is for. Conversely, it is possible that the court entered an Order for temporary custody (OTC) pending this hearing but you normally only see that in neglect cases brought by the Department of Children and Families. In any event, your girlfriend would need to file an interlocutory appeal on Monday or it may be possible that the grandparents will seek enforcement of the temporary Order on Tuesday.
Regardless, at the upcoming hearing your girlfriend will want to be prepared to present her own testimony and call any other witnesses on her own behalf such as yourself, along with any other evidence she has to rebut the claims being brought against her.
Obviously this is a very serious situation and I would highly recommend that your girlfriend immediately retain a family law attorney licensed to practice in your jurisdiction. Many attorney's offer free consultations and offer monthly payment arrangements. Also, her attorney can request that the court order the opposing party pay her reasonable attorney's fees.
I hope this helps, best of luck!
