Joint ownership + settlement question

she can go for settlement deed  for both the properties,favg you to two people with life settlement. and it has to be registered now for her convenience,If it remains unregistered till her life time and after that, by virtue you both will become owners of those properties.

Adv. Raghavan - Thank you for your response!   A more basic question - Does my mother get the properties automatically without any further action or is half of the property shared between my mother, sister and I? 

I do not under stand the context of this question, but by virtue your mother gets all the property held jointly by your father and mother, after your fathers demise. Now it has become your mothers own property, she has the right to do what ever she wants. You people have little say on this.

Well, another lawyer in Chennai told me that since the property was jointly owned by my parents, my mother gets her half and the other half would be split equally between (1/6th each) her, my sister and I.  We would have to register release deed to release the house in her favor.  Hence my question. 

Thanks for your clarification that's NOT THE  CASE.   Procedurally, what does my mother have to do establish full rights?  - File death certificate with registrar, etc??  - Or does she not have to do anything at all? 

Sir Better you go for Release Deed, Stamp Duty also similar as Settlement deed, because Only half share of the joint ownership property your mother  having absolute right another half share your mother you and your sister entitled for 1/3 share (after death of your father as per succession act your mother , yourself and your sister are I Class legal heirs) 

tenancy by the entirety n. joint ownership of title by husband and wife, in which both have the right to the entire property, and, upon the death of one, the other has title (right of survivorship). 

if your father had left any will, favg you people regarding his share in that property, you can claim the same . In the absence of the of above u have little chance to claim.

Mr. Raghavan and Jayakumar - Thanks for your responses.  It looks your responses are in conflict.   The sale deed from the builder to my parents does not state the type of joint ownership (tenancy by entirety, etc.) but I assumed they would jointly own the property and the survivor gets the entire property.

I'd appreciate further discussion with the esteemed legal community here and resolution to this issue (whether my Mother owns the property completely or not). 

The intent within our family is to settle both properties collectively on my sister and I and we can resolve the division later.  My mother will have life interest in the property.
