It depends on several factors: was there a prenuptial agreement that would control? If not, was there a will? Were there joint accounts with right of survivorship? Was there "exempt property?" If there was no will, what is the law re "intestate succession" (without a will) in the state where your father died?
I suggest that you contact an estate administration / probate attorney for a definite answer. All of the answers to the above questions will have to be considered for a final answer.
It depends on how the property was titled and if he had a will or other estate planning documents. If he owned the house 100% and if he died without a will, in SC the estate is devided 50/50 with 50% to his spouse at the time of death and 50% to his surviving children.

Keep in mind the statute of limitations in SC may be a short as 1 year. Most cases have a 3 year statute of limitations, suits against the state, defamation cases, workers compensation and some other cases have a 2 year statute of limitations. Some cases under § 15-3-560 have a ONE YEAR statute of limitations. Do not sit on your rights.
