How to sell my self purchased property jointly my minor kids as co-owners without court permission ?

Respected board of lawyers, How to sell my self purchased property jointly registered with my wife & my minor 2 kids as co-owners without court permission ? I am a resident of kolkata. In march 2017 i purchsed a property consist of land & building in kolkata and i paid the full consideration of registered sale deed though my own funds without any loan. I have mentined myself (as self purchaser) + my wife + 1 minor son + 1 minor daughter as owners of the said property. Mutation is also done in all 4 names of my family members. Now i need immediate money to support my business & me and my wife decided to sell the property. We are staying in a different property owned by me (no one is staying in the property that we intend to sell). Now when we tried to sell the property, buyer is asking for court permission for minors. We consulted local lawyer but he said that it will take minimum 1 year to get the court permission. If i do not support my business with money then i have to close my business, so please mercy on my family and give legal opinion how to sell our property without obtaining court permission. If my business is closed then i have no other alternate of surviving with my family. Me & my wife are ready to give any sort of undertaking but help us to sell the property legally (protecting buyers interest). Thanking you.
