The girl's lawyers claim her mother even suggested slipping her daughter "an abortion pill through deception."
Further allegations include claims that the girl is being kept from school and had her phone and car taken away as punishment for not going through with the abortion.
"[The teen's father] stated he was going to take her to have an abortion and that the decision was his, end of story," the lawsuit says.
Texas law prohibits parents from forcing their child to undergo an abortion, even if that child is a minor.
A judge has issued temporary restraining order preventing the parents from contacting the girl. The next hearing has been set for this Friday.
