Can Abusive Grandma Actually Take My Fiancée To Small Claims Court Or Is She Just Being Insane?

Hello!!

Okay so my fiancée (I will call her Sam) was raised by her grandma from the age of 3 due to some unfortunate circumstances. Her grandma is also fucking insane.

A little over a year ago, Sam moved from Florida to Illinois to live with me. She didn’t have a job lined up yet because her career required her to transfer licensure etc whatever it’s not relevant. I couldn’t afford to pay for all of our expenses, so to help with moving costs and living expenses, her grandma let her use a credit card of hers, which was really helpful. She was having my fiancée pay her back $100/month once she started getting paid.

A few months ago, they got into an argument over Sam asking her to stop talking shit about her ex wife, who also raised Sam and is functionally her mom and has always had a great relationship with Sam. This caused her to tell Sam that she’s dead to her and all this. She keeps trying to piss Sam off every few weeks by saying deranged shit like she wishes she never took her in etc. even though Sam literally does not answer her, she just keeps sending her the $100 every month. Today, her grandma said she wants her to start paying her $250 a month and that she’s taking her to small claims court.

We are wondering if she can actually take her to small claims court over this and what would happen if she did. Neither of us have enough money to pay it all off (currently $1775) and she can’t afford $250 a month but I think we could make it work if we had no other choice. If it helps, the credit card had Sam’s name on it but she’s no longer an authorized user.
