A new Web site promises one-stop shopping for bankruptcy court data nationwide. BankruptcyClearingHouse.com provides bankruptcy filings from courts in all 50 states, the District of Columbia and Puerto Rico. Data for most courts dates back to Jan. 1, 1997, and is current to within a few days. Users can pay by the search, at $1 each, or have unlimited searches for a flat rate of $50 a month. The service allows you to prepare custom proof-of-claim forms and save them to use again later.
