OK, this is a complicated matter, and I do suggest that you get an attorney in your area to assist you with this.
When you married your husband in community of property, you automatically became owner of 50% of his entire estate, which aould have included the members interest in the close corporation. In other words, when he resigned in 1999 and sold/gave/transferred 100% of the memebers interest to his brother and your son, such a transfer would have been unlawful - he could only transfer 50% of the members interest.
The complications are endless, because you will have a claim to 50% of the corporations profits over the years as well as you were entitled to it.
So, in short, you are entitled to half the joint estate and 50% of the members interest in the corporation. The fight surrounding the corporation however will not be easy (because it was long ago). You WILL need expert assistance.
Your husband's 50% of the estate is not necessarily to be divided between you and your children - it depends whether he left a will, and if so, what the terms of the will was. If he died intestate, then yes, you and the children will inherit together. You will be entitled to a child's share (R250 000,00) and the children will inherit the balance.
I hope this answered your question.
