Father's property without will

Respected lawyers,

                       My father has left no will. My Mother is 83. I am 65. We are six children to our parents. Because of getting old as per the Lawyers guidance, we the 5 children agreed for a family settlement deed of our father’s flat property to share equally after our mother,s period and tried our maximum  level best to convenes our mother & a widow  sister (single living), in the presence of family friend as well as a lawyer.

              But that sister is very adamant for not to sign in the agreement & also keeping the Original flat doc., in her custody. This matter is dragging for the past 2 years. The flat is in Chennai & its present market value is RS. 80 lakes.

             I am afraid because of a B/P patient & hospitalized once for a mild attack & now under medicine, my only  daughter after my life may not take up the legal battle with my family for my 1/7^th share. Hence I want to get the settlement deed to be signed by all seven now itself or  the partition order through court.

            Even then after me & my mother’s period the trouble making widow sister forcibly taking passion of the flat by having our mother’s share in her favor & refusing to settle other 5 legal hires,because of having rights to live in her 2/7^th share & preventing other 5 legal hires to get their money through sale of the flat to any 3^rd. party .

            Under such circumstances how the court of law will help the majority of the legal hires to get their father’s property monitory benefit through sale. I can give guidance to my other brothers & sister for jointly  take legal steps along with my wife / daughter as per your  proposed valuable  guidance.

             Expecting your valuable guidance for the best efficient way to get our father’s property Five shares monitory benefit, by overcoming the expected exploitation mentality of our single living widow sister.

                                                                                    With kind regards

                                                                                    K.Chandrasekar.
