Speaking from experience, you can get a divorvce here as long as South Africa acknowledges Swiss divorces. Easiest way is to call the embassy and ask. Mind you that most Swiss style divorces take 2 years if all parties are in agreement. Also the breadwinner pays 1/2 of the pension fund that was accumulated during the marriage to the other spouse.

I remarried 14 months after my divorce was finalized, so it could be done.

Not quite correct. Divorce in Switzerland takes 2 months, if both parties are in agreement.

When there is a dispute, the seperation of 2 years takes place, after which the divorce will proceed, irrespective of one party not agreeing.

South Africa would have nothing to do with the divorse as the marraige was obtained in Greece to a German national while the gent was resident in Europe. I doubt that the marraige is even registered in any way in South Africa.

South Africa has signed treaties implying that they would care, or should. I know you think south africa went mostly backward in the last 15 years, but they did at least bother to sign stuff.

A marraige is registered in the country where it is obtained. It is up to the parties to that marraige (husban/wife/etc) to register that marraige anywhere else in the world. South Africa and Poland had no idea about the marraige that me and my wife had in the UK. Poland was only told by us registering it there when we transfered property and were only interested because it meant that there was no transfer tax to be paid.
As I understand not even the EU currently shares a common marraige register so I seriously doubt that South Africa would have one with Greece.
If you read the link that one of the pervious posters to this thread had posted you would see the implications of that.
