The laws in North Carolina are pretty basic as they mentioned that if your grandmother does not have a will then all of the land will possibly land in probate, which it will take months in order to complete the process in order to distribute the property depending on the order of relations.
Depending on your specific situation, there are many items that may need to be addressed. I would first contact the North Carolina Administrative Office of the Courts for help.
If you grandmother had a last will and testament properly filled out the land goes to whomever she wants. If not it goes to probabte and to the closet heir.
There are many factors that will determine how the estate is handled. The worth of the estate, who is listed as the executor and even the cause of death.
