I need some guidance to make the right decisions regarding the following matters:

If I have an existing bond(without credit life cover), a few thousand Rand of debt and a car all paid off, and I was to pass away intestate without a spouse or any children, what will happen to my estate? Will there be any liability placed on my parents or siblings to repay the debt?

What would happen if this same scenario if I were to marry in community of property, out of community, and with the accrual? And what would happen in these scenarios if I had a will drafted where I bequeth my estate to my loved ones?

Also, how will I make provision for my family to continue paying for all the debit orders that would be supposed to go off my account?

Trying to get my affairs in order.
