Definition of 'Account Freeze'

Account freezes can be initiated by either the account holder or a third party.
Investopedia explains 'Account Freeze'
An account may be frozen by government or regulatory authorities because of suspicious activity, suspected criminal activity, civil actions or liens filed against the account. Furthermore, a bank or brokerage account may be frozen when the account holder dies. Once the appropriate documentation is presented, a new account will be opened in the beneficiary's name with access to the assets.
