D.C. Mun. Regs. tit. 10, r. 10-B2232
The District may setoff against the claim of an otherwise eligible displaced person any claim which it may have against that person arising out of the use of real property owned by the District, subject to the qualifications set forth in this section.
Before making a setoff, the District shall notify the displaced person of its intention to do so and shall advise him or her that he or she may within thirty (30) days file a statement challenging or opposing the setoff.
If a statement challenging the proposed setoff is filed and the District institutes within thirty (30) days after the filing a judicial action to recover the amount claimed, it may tentatively set off the claim.
If the District obtains a judgment for the amount claimed, or any part of the claim, the amount of the judgment shall constitute a final setoff.
If judicial action on the claim is instituted by the District and judgment is denied for the whole claim, or if the District fails to institute judicial action, the District shall pay the full amount of the relocation claim for which the displaced person is eligible.
No relocation payment shall be made from the District funds in any case where a payment for a similar purpose is authorized by an Act other than the Uniform Relocation and Real Property Acquisition Policies Act of 1970.
