Jane and Jack got married on 5th May 2015. Jane was an accountant by profession and Jack a high school teacher. Jack got very close to her colleague Suzie and Jane did not like this. Jane and Jack started having arguments. Eventually in September 2016 Jack left the house which he shared with Jane and moved in with Suzie. Jack and Jane wish to amicably end the marriage, and share the property. Jack agreed to transfer his share of the property (house) to Jane for $100,000. Jack agreed to transfer the car to Jane if Jane allowed his mother to stay with her for 2 years and took care of her while the Mothers migration to Australia is being processed. Once the transfer papers were ready Jack changed his mind and refused to sign the papers asserting that Jane should pay her more for the car and the house. Was there a binding agreement.
