If you have purchased a piece of vested land in Liluah, Howrah, you may face some legal problems in the future if you construct a home on this land. Some of the possible issues are:

• 
  Invalid title: Your title to the vested land may be invalid or defective as the seller had no right or authority to sell the vested land to you. The state may challenge your title and claim ownership of the vested land at any time. You may also face difficulties in obtaining mutation, registration, or tax clearance for the vested land.
• 
  Eviction: The state may evict you from the vested land if it finds that you are occupying or using the vested land without its permission or for any purpose other than agriculture. The state may also recover rent or damages from you for the unauthorized occupation or use of the vested land.
• 
  Demolition: The state may demolish your home or any other structure that you have constructed on the vested land if it finds that you have violated any law or regulation regarding building, planning, or environment. The state may also impose a penalty or fine on you for the illegal construction on the vested land.
