R.Ramachandran (Advocate) 14 February 2018
Since your father has not left any WILL, the property has to go equally to you and your sister. Without your sister's consent, you will not be able to sell the property. First you have to apply for and obtain Legal Heir Certificate. The legal heir certificate will mention all the legal heirs of your deceased father (needless to say it will mention your sister's name also). Once Legal Heir Certificate is obtained, then both you and your sister have to execute the Sale Deed by both of you signing the Sale Deed.

When the head of the family or a family member passes away then the next legal heir of that person can apply for the legal heir certificate.
