Registration of a trade name with DCRA does not guarantee or warrant that another person has not or will not register the same trade name with DCRA.
DCRA's acceptance of a trade name registration shall not in any way be deemed a warranty of the applicant's right to do business in the District under the name registered, nor shall it be deemed a guarantee that the applicant is exclusively using the trade name in the District at the time of the grant of registration.
DCRA shall not be responsible for determining whether there is an existing person carrying on, conducting, or transacting business using the same trade name.
