My brothers so called Fiancé ( de facto) convinced him to draw his savings out of fund to invest in a property deal, the money on investigating, went into her bank account. Following more investigating have found out she has lied since the beginning of the relationship (9 years approx.) about almost everything. Date of birth & year of birth, where she is living & more. She did promise to pay him $200,000 when she sold her house but she has not put it on the market. He has called off the engagement, telling her there never was a true relationship. She also has a insurance policy on him, for accidental death, naming him as her spouse. Is there anything we can do under family law?
