Bella is married to Fred. She met Fred online and moved from South America to live in Australia with Fred. Bella speaks English, but is not proficient reading and writing English. Bella works in Fred's business, and they work up to 80 hours a week buying, packaging and delivering flowers.

Fred believes they need a new van and also some new equipment in order to facilitate the business, but this will require borrowing from the bank. Fred takes Bella to the bank and tells the manager organising the loan that Bella is his partner, and that they need to borrow $500,000. Bella is presented with various documents which she signs, Fred does all the explanation to Bella, the lender asks Bella if she thinks everything is okay, and she replies yes.

Two months down the track, the business is doing very poorly, Fred has moved interstate and is not contactable, the bank has sent a notice threatening legal action and Bella is now discovering the extent of her legal liability.

What might be Bella's rights under contract law? Can she put up some reason why she is not bound by the contract?
