One of the common misconceptions about filing for bankruptcy is the 90 day rule. If you ask debtors that are filing bankruptcy if they understand what the 90 day rule is, you get answers like, you can't buy anything for 90 days prior to the bankruptcy filing or you stop paying your bills 90 days before filing. Both of them sound like they could be true, but in reality there is no 90 day rule that makes a difference to a debtor.
Many debtors filing for bankruptcy have heard of it but have no idea of how it works. The 90 day rule allows the bankruptcy trustee to recover payments that a debtor made on legitimate debts, if those payments during that 90 day time frame gave the creditor more money than they would have gotten out of the bankruptcy filing. The bankruptcy code calls these payments, preferences.
