'Responsibility to provide'
The mother, identified only by her surname Luo, raised both her sons after she and her husband divorced.
Ms Luo said she had spent hundreds of thousands of dollars funding both her sons through dentistry school
but became worried they would be unwilling to care for her in old age.
Subsequently, she signed a contract with both of them stipulating they would pay her a portion
of their earnings as repayments for the school fees, up to a total of $1.7m.
