Banks may have to give farmer borrowers up to two years to arrange the sale of their farm following a loan default, if a private member's bill before parliament attracts support.The Katter Australian Party on Friday introduced a bill that addresses long running complaints by indebted farmers over the conduct of banks selling security properties.The bill "requires the financial institutions to provide the borrower who is in default of their credit agreement with a notification setting out their claim of default," Bob Katter explained in documents lodged with parliament on Friday.  "The borrower then has a two year period in which the financial institution cannot exercise its power of sale, providing the borrower with time to market their property for sale in order to achieve maximum sale price."Katter set a minimum land value on a farm of A$150,000 in the bill. Debts on farms with a land value of less than this threshold would not be affected by the bill.The bill also "provides adequate protection for the financial institution within this time period by requiring the borrower to continue to make interest payments on the credit amount, so long as those interest payments do not amount to default or penalty rates of interest," Katter said.  He said the bill also "prevents financial institutions from imposing on the borrower any default or penalty rate of interest, additional charges, penalties or impositions however they may be described, that were not in place before the default arose.   "Finally, the bill prevents confidentiality clauses in settlement agreements."The scale of the problem considered by Katter's proposed legislation is not spelt out in the explanatory memorandum circulated with the bill, and is mainly assumed to exist on the basis of noisy media and social media campaigns (with the Bank Reform Now group on Facebook being an archetype of the activism over lending practices).
