The domain deletion is a procedure for the removal of the records on the domain from the WHOIS database.
The domain holder can decide not to renew the domain by not making a payment and cancelling the renewal order on his/her account. In this case, the domain is deleted after its expiration.
If the domain holder wants to delete the domain before its expiration, he/she has to send a notification about the termination of the agreement made by the domain holder by email email@example.com.
A request by a natural person and a legal entity can be signed using a qualified electronic signature.
If the request by a natural person is not signed by an electronic signature, a copy of the personal identity document has to be attached to the request. The request by a legal entity has to be signed by the head or the authorised person and a copy of the document certifying the authorisation has to be attached.
