ancestral property

I have seen many persons using the term 'Ancestral property' without understanding its legal meaning.

Therefore, before answering your query, it will be advisable for you to trace the history of the property i.e. to begin with (i) who first owned it - (ii) in which year he got the property (iii) whether that person is alive now; (iv) if not alive, in which year he died etc.;

then (i) who got it next;  (ii) in which year he got the property (iii) whether that person is alive now; (iv) if not alive, in which year he died etc.;

like that upto the Father in question now.

Only after going through the above history of the property, one can really tell answer to your query.

You have not given even the basic information wanted by me.

Therefore, the question of my letting you knowing anything for any further information simply does not arise.

If you are interested, read my first response.

While you answer the above mentioned points, pointwise you may also clarify:

What exactly you mean from “Great grad father had given to his 4 sons..”?

Was it partitioned by a valid/registered deed say; partition deed?

Who is appointed as ‘Guardian’ of said mentally retard son?

Which personal laws applies in this case or are all involved Hindu? Is the said grandson also a Hindu?

Generically Speaking; The father (principle) as in query has been sensible to sign PoA to the extent of his share only…………by appointing daughter (as in query) as agent..in PoA……

The daughter can neither take charge of whole property by virtue of said PoA (or otherwise) dispose more than share of principle of PoA……….

The agent has to maintain trust of principle…
