Getting a loan while you are under administrator in South Africa is illegal, so if you want to take out a loan and you are under admin the first thing you need to do is to contact your legal administrator.
The administrator is the one who handles your financial decisions & money management for you, Therefore, perhaps your first port of call should be with the person who has been appointed to manage your financial affairs.
Discuss the problem with your legal administrator & look for a sensible solution to your immediate pressing financial requirements.
So when you really need extra money, and while it is difficult to accept at the time, the most sensible thing to do is to tough it out, exercise extreme discipline & you will eventually get through the bad patches.
However, the worst thing you can do is to get into more debt just for short term relief, as in the long term it will not only be against the law, but it will have an extremely adverse effect on your debt situation & end up making your financial woes even more dire.
