District of Columbia General Forms (GDN)-Notice of Registration are documents that provide notice of registration of a particular document or instrument in the District of Columbia. These forms provide a legal record of the registration of the document or instrument. They are typically used for real estate transactions, wills, trusts, and other documents that must be registered in the District. There are two types of District of Columbia General Forms (GDN)-Notice of Registration: Gdn-1 and Gdn-2. Gdn-1 is used when registering an instrument or document that does not require recording. Gdn-2 is used when registering an instrument or document that does require recording. Both types of forms must be signed and notarized before being submitted to the District of Columbia Recorder of Deeds.
