How do court summons get legally issued in South Africa? The question refers to the recent threat by SANRAL (South African National Roads Agency) to issue summons on outstanding e-toll bills.

Thus, do these court-summons have to be handed over in person and receipt of it acknowledged? Do they get delivered to a physical address only? If yes, would registered mail be compulsory? Or can court summons just be placed in a post box or letter box?

Your legal opinion and advise is much appreciated!
