Daughters right In father property

Has the deceased father mentioned details of the property?

If not the size or share/interest?

The details you gave in your query are quite insufficient to give proper advice.  If he did not mention in his will how much share each son and daughter will get, then all of them, his mother and wife will have equal shares.  So, if the sons cobble together to deprive the women folk of the family their legitimate right (women includes testator's mother and wife), do not agree for such settlement and let the court decided the shares as per law.

Who has original WILL and who else have copies?

The WILL exists then it is last wish of testator and is supreme.

You mayclaim share.
