My mother in law gave my husband money (amounting to A$25,000.00) as 'gift' in order to get a house (mortgage); after a year, when she learned that my sister in law paid my husband the money my sister in law owes (A$50,000.), my mother in law asked my husband to pay her back! And now she's suing us; we we're stunned & shocked! It was so upsetting because. D money that my sis. In law paid, we put it already as payment in our mortgage too. This is so disappointing! Any comments?
