First of all, your intended split must create at least (2) minimum-sized lots... with minimum frontage and minimum Sq.Ft. or acreage.
Then, you will need to have your property surveyed for the split. After that, you need to have your lot split recorded and a new parcel ID number assigned to the additionally created lot.
I hope this helps.
