This could be a doozy. if your husband was gifted "7%", with no specific location or description, meaning he received a 7% interest in the whole 84 acres, he has to do one of two things: (1). Get all of the heirs of all of the siblings to agree on a physical division of the property into pieces, or (2). File a partition suit so that the whole parcel is sold and your husband receives 7% of the net sales proceeds. If your father in law's parcel was never surveyed off and separated from the 84 acres, it will take a bunch of signatures to get clear title to a portion of the 84 acres.
It all depends upon the description of exactly what was gifted to your husband, whether a defined parcel, or 7% of the whole.
