You need to consult with legal counsel in South Carolina. However, you may want to explore with him something called a "qualified disclaimer." Using such a disclaimer may allow your siblings to give up their ownership interests before you file any deed for the property. This disclaimer has the impact of the disclaimer party predeceasing the decedent for all purposes. The tricky part here is that you must check the intestate laws in your state to see if any of their descendants woud take their share. If so, they must disclaim also. This needs to be explored with an attorney.
In the alternative, you could explore your siblings making gifts of their interests to you and your husband.
Finally, be aware that the qualified disclaimer rules are detailed and complicated and there are time limits involved in their usage.
