Hi Khidistavi,

While I did not find a source that exactly said that Yaradullu is De Facto under the  Republic of Armenia, I did find a source that says that part of Yaradullu is in the territory of the Republic of Armenia. It is from Civilnet. I think its best if we put the name like this: Yaradullu - Յարադուլլու.
