Sister and Her Husband Claiming Property

She can claim her share only  after the death of parents and can claim only ancestral property. Distribution of Self acquired property is totally on the discretion of parents.

If it is self acquied property of the parents then sister cannot claim her share, if it is ancestral being a co-parcener she can claim her share.
 

thank you arvind and rajoo sir for the timely and precise advice

Law of sucession is governed by parties' relegion. Hindus have Hindu Sucession Act while muslim

have qurans'law.Among Hindus there were 2 concepts Mitakshara co parcenary and Daybhag law ruled by

Different schools in differents parts of India.In dayabhag law property devolves from father to son but in case 

Mitakshra law a property devolves not only on son but also on grand sons and this rule is still saved in Hindu

Succession Act with only one qualification that in olden days females were not to form a part of

Hinducoparcenary but  now law recognises them as coparcenors.so sisters can claim equally with brothers

if the property in hands father has come from their GRANDfather  even in life time of the father but in case the

property in hand of the father is his own creation. none can claim it during his life time.the husband(a son in

law )can have no claim in either of cases. 

In muslims there is no terminology like ancestral or co-parcenery!! 

i agree with  soni sir
