Ex is lying on his financial statement... STILL>

Okay so it has been almost a year since this whole court mess started.  My ex and I both had to submit a sworn financial statement.  We did however my not so bright ex stated in one of our many court hearings that he had got a raise in his income.  So ofcourse my attorney picks up on that statement made by ex and asks that he submits his tax return for 2008 and his most recent paystubs.  This was in January of this year 2009.  We just had our last court hearing this past July and still did not have the returns or stubs.  At the end of the hearing my ex's attorney says he's been trying to get my ex to submit the information and he will have a new sworn financ. statement by the end of business day and the tax returns and stubs by the end of the week.  The financial statement came in however it was not any different than the first one except this time my ex is saying he was paying our mortgage and his rent payment.  Our house just forclosed on 09/02/09.  Any how my attorney got fed up with this and filed a 'Motion to Compel' and the court granted it.  My attorney said that my ex will now have to supply the return and statement because the court has ordered him to do so.  I am just wondering if he doesn't comply with this what will happen to him?  And how long can the courts go on not realizing that he is lying on his financial statement?  I mean he makes almost $20k more a year than I do and he is saying he takes home a net pay of $800. a month but paying $800 in rent and $1400 in a mortgage not including other bills.  I am so lost in this.
