Lawyers in Colorado who pass on to homeowners the court costs of filing a foreclosure lawsuit against them would have to prove they incurred the expenses, under a state legislative bill introduced recently, the Denver Post reported today. Additionally, foreclosure lawyers would be required under the bill proposed by Colorado Rep. Beth McCann (D-Denver) to keep receipts and other proof that demonstrate that the expenses they say a homeowner must pay to end the foreclosure process are real. The legislation, HB-1130, unanimously passed a Colorado House subcommittee on Wednesday and will be heard by the entire assembly. If it passes the House, it will move to the Senate for hearings.
