WASHINGTON (AP) — The District of Columbia is beginning the process of re-registering firearms.

The Washington Times reports the re-registration process went into effect Jan. 1 and that renewal is required for an estimated 30,000 guns registered before 2011. The renewals will be staggered through December 2015 based on the gun owner’s birth date.

The city passed a firearms law in 2008 that requires gun owners to re-register their weapons every three years. The law is currently being challenged in court, but the case has yet to be resolved.

Police say renewing a registration will cost $48, no matter how many guns a person owns. Registration also includes fingerprinting and passing a background check.
