What is the Name-Holding Deposit Check Tool?
A name-holding deposit is a deposit where the account holder's name differs from the beneficial owner. For example, in a case where a grandfather creates an account in his grandson's name and deposits money monthly, even if the name is the grandson's, the beneficial owner may be judged to be the grandfather. In this case, it must be declared as inheritance property upon the grandfather's death.
This tool is a web tool that allows users to pre-check the risk of such name-holding deposits before an inheritance occurs.
