Need Help With Colorado 1972 Subdivision Law

[Mike T.]

I buy and sell a lot of Vacant land.  Recently I purchased a 10 acre Parcel in El Paso County Colorado about 45 minutes east of Colorado Springs.  It was assessed by the county for 27,000.  I have an easement for access.  I bought title insurance.  It is zoned A-35.  I had the piece of land under contract to sell very fast and the buyer was a builder who was going to buy the land.  When he called the building department to make sure he could put a house on it, The building department stated this land was illegally split because back in the 80's the owner split it within the family and did not get county approval for parcels under 35 acres and it is a dead parcel with no development available.  

I have paid an attorney more money that I want to find a solution and they want  me to sue the title company.

Has anyone had any experience overcoming this obstacle with the county.  I just want to be able to throw a manufactured home on it (or sell it so the buyer can do this)
