A 25-year-old is seeking legal advice regarding potential inheritance claims as their father is seriously ill. They are concerned about their father's sister claiming savings if there's no will or if the father wills assets to siblings. They also worry about the aunt fraudulently influencing the father to disinherit his wife and son. The main concern is whether they, as legal heirs, can claim assets like FDs if the father, a banker, changes beneficiaries, especially if he passes away.
