Your query is not clear on one question. At one place you say your father sold away  that property y along with his younger son. At another place you say he gifted it to  someone. In the same vein you say it is  not parental or your father's ancestral property.That means  it is your father's self acquired property.Your father being the absolute owner  can deal with the  property in whatever manner he likes such as selling or gifting tosome one etc. His children have no legal right to  your father's action of selling or gifting  of his self acquired proerty by your father.If you appreciate this answer please click the thank you button on this forum.

Dear Sir,

            I am clearing about acuisition of property by my father. He is now out of mind being more than 80 years old and he is foster child of his father. but the documents of property belong to my fathers name. Now the property was sold by him to another person without informing us. we came to know now after 4months, but mutation under process but with our application to Tahasildar, the process is stopped now for time being.

kindly suggest  me the process or civil law by which we will return back our property. am thinking about permanent injection (156) is it wise for this?
