Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company has financial instruments, including accounts receivable, accounts payable, loan payable, notes payable, and accrued expense. Due to the short term nature of these instruments, DLH estimates that the fair value of all financial instruments at June 30, 2014 and September 30, 2013 does not differ materially from the aggregate carrying values of these financial instruments recorded in the accompanying consolidated balance sheets. In addition, the Company has historically presented certain common stock warrants and embedded conversion features associated with Convertible Debentures and accounts for such derivative financial instruments at fair value. As further described in Note 12, those convertible debentures matured and the common stock warrants were exercised in the three months ended December 31, 2013.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities.
