My Grand Father i have two waives, 1st wife 4 members, 2 sons and 2 daughters. 2nd wife 4 members 1 son and 3 daughters. My grand father dead 25 Jan 2003, My father Dead June 30 2004. after this we had Unregistered partition with family and Pachanyathdhar main persons of near by Villagers. 01-Nov.2004. we did not taken signed by Daughters, we have communicated daughters and participated in this arrangement. (Amendment came 09-Sep-2005 - But we done partition at 01-Nov-2004) We have never heard 1908 reg act col 16/17 mandatory registered the partition deed, also that day we do not know need signed by daughters. due to communication gap) today we have social media immediately get news) Two daughters dead one is 09-May-1992 and 25-Oct-2002. RTC done at 25-Jan-2005 few and few 10-Jun-2010. since today we have paid taxes. Revenue tax every years. Now one of the Daughter have asked need property, Orally she was asked. Here my question is Daughters have still eligible for property thru court? why revenue department allowed unregistered deed to further proceed. if we ask any government order they told no order copy.. until 09-sep-2005. amendment came. according to Hindu succession act 1956(HSA), around 2010 after revenue department started mandatory for registered portion
