DENVER (AP) -

The Colorado attorney general's office is investigating whether law firms specializing in foreclosures are inflating fees that homeowners must repay to avoid losing their houses.

According to court documents, law firms pay as little as $25 for someone to post official notices on a property advising homeowners of their rights, but some firms are charging as much as $150 in the bills they file with the public trustee overseeing the foreclosure case.
    
The Denver Post reports the fees are limited to the amount a lawyer actually paid or was billed for a service or expense such as mailing costs, property inspections, title searches and court charges.
