A blunt knife or rusted knife can't be useful for anything just for the sake we call it as the knife similar to PayTM series or Sachin or Virat records.
Only a highly emotional or insane person will do it.
I have read one article by the son of the computer giant Bill Gates where he mentioned that his father has appointed him in a manager level place in his organisation and some fixed salary was given to him which in his view was insufficient being the son of such a rich man.
Anyway this will be different for different parents how much they consider for their children.
Knowledge is power.
Nowadays the parents are keeping their children as nominee to their deposits in case of death.
Whatever we earn is for sure to our children only. But father has to think about his wife also. If the father dies the mother will become alone and children may or may not take care of her. So some reserve money should be there on her name also. In such case she will not have much problems. we can distribute assets to children while we are alive but we should keep something for self so that we are not dependent on anybody at least for financial matters.
So it is better to be prudent for the parents to make a clear will about the assets and wealth distribution among their children . Otherwise they can make it a conditional deed that the ownership will pass on only after the death of both parents .
Nowadays there s a facility for 'Reverse Mortgage" wherein the elder people get a regular income by motioning their assets to a bank and the legal heirs can redeem the assets after the death of the elders by repaying the loan availed liability. Otherwise the bank will take the assets in recovery as per terms.
