22 GCA § 12106: Notice.

Whenever any notice is required by this Title, it shall be in writing unless expressly otherwise provided. Any required notice may be given by mailing such notice, postage prepaid, addressed to the person to be notified, at his last known residence or his principal place of business, unless expressly otherwise provided. An affidavit setting forth the facts of such mailing by the person doing so is prima facie evidence of such notice.
