yes 1099-NEC and not 1099-S 

Just received additional details: The wife's mother owned the house, she passed away, house was passed down to his wife who also passed away, house was then passed to him and his wife's siblings* (not his step children). Sorry for the confusion- I mistook the "children" to be his wife's children and not her mother's children.  

No will and no settlement sheet just the 1099-nec from the attorney.
