What is the law regarding division of undeveloped land if it is inherited by multiple people?

My Mother recently died and her estate is to be divided equally between myself and my 2 siblings (we are all in our 60's). Part of her estate is 79.8 acres of undeveloped farm land that joins 40 acres of property that I have lived on with my family for 42 years. I purchased this 40 acres from my parents in 1994, when I got ready to build a home. I have lived on this property since 1979 in a mobile home before purchasing this from my parents. The 79.8 acres is to be surveyed and split into 3 parcels that are 26.6 acres each. Of course I have always fully expected for my 26 acres to join my existing property. Both siblings who are inheriting live over 50 miles away from the property and have never taken any interest in the farm. My brother wants to "draw straws" for the parcels instead of me automatically getting the 26.6 acres that join my existing property. Is there any type of law protecting me from this?
