If you don't have the knowledge to handle wealth you can lose it suddenly.
Many people who find themselves suddenly wealthy often find they face an unexpected problem of losing that wealth suddenly. The biggest problem is that people who become suddenly wealthy do not always have the knowledge to handle their finances in a way that ensures there is always enough money coming in to cover obligations.
As Private Wealth points out in "The Downside Of Sudden Wealth," the syndrome is not just due to quickly becoming wealthy. The syndrome refers to the common problem of people who become rich suddenly ending up with less wealth than they previously had.
There are several reasons for this phenomenon. For example, they might overextend on credit card or mortgage debt and not have the resources to service the debts when they have spent all of the money they received.
If you are planning to leave a large inheritance to someone who has never before been wealthy you might considering contacting an estate planning attorney who can give you guidance on handling the issue.
