Daughter right

Which personal law applies in this case e.g; Hindu?

The property in the hands of A was self acquired/earned/HUF/Joint/ancestral?

Generically speaking:

and Believing that 

A was male and the property in the hands of A was self acquired/earned and all are Hindu.

Succession opens on date of death.

Believing that on date/month/year of death of A, his mother and wife were not alive and he had no daughters and B was son of A. Hence B was lone ClassI legal heir. Thus as posted by you B inherited whole estate of A.Nature of property acquired by inheritance is self acquired.

Believing that on date/month/year of death of B, his mother was not alive. As posted by you and B had no sons & daughters. Hence C (wife of B)  was lone ClassI legal heir. Thus as posted by you C inherited whole estate of B.Nature of property acquired by inheritance is self acquired.

C adopted a son D by valid means/deed. Adoption is not faulted.

How did  property of C devolve upon D? 

Say inheritance i.e. after death of C?

The property from mothers side is not ancestral.

Property of Hindu female if acquired from husband's side devolves upon heirs of husband if sons and daughters are not present.

Pls clarify the details.

The property originally belonged to A though he inherited his ancestral property.

After A's lifetime the property devolved on B.

Upon B's intestate death this property devolved on his only surviving legal heir i.e., C. 

Upon adoption  of D by C, D becomes a proper legal heir to C and assuming C died intestate, D acquired as surviving legal heir/successor to his adoptive mother. 

Thus this property becomes an absolute property of D  and during his lifetime he can transfer this property by any means to anyone of his choice and in any manner he desires. 

Thus the testamentary disposition of the proerty through will to his grandchildren is legally valid and his Daughter has no rights to claim a share  in this property by any means.

In case she files a case for partition also, it may not be maintainable or valid in law.
