D.C. Mun. Regs. tit. 16, r. 16-118
If a buyer is in default in the payment of any sum due under a contract subject to this chapter or in the performance of any lawful condition imposed by the contract, the seller or seller's assignee may when authorized by law repossess the goods secured under the contract.
Unless the goods can be repossessed with the permission of the possessor obtained immediately prior to the repossession, and without use of force, intimidation, undue influence, fraud, or breach of the peace, the goods shall be not repossessed except by legal process.
Nothing in this section shall be construed to authorize violation of the criminal laws of the District of Columbia.
The disposition of repossessed goods and the application of any sums realized by the disposition, shall be in accordance with applicable statutory law, including D.C. Code §§ 28:9-504 and §§ 28:9-505 (1981 Ed.).
The seller or the seller's assignee must account to the buyer for any surplus from the proceeds of disposition as provided by D.C. Code § 28:9-504(2)(1981 Ed.), notwithstanding the absence of buyer liability for a deficiency.
