Legg Mason does have minimum age requirements for opening an account, which typically aligns with general financial regulations. Generally, individuals must be at least eighteen years old to open a personal investment account in their own name. For those under eighteen, a custodial account may be required, which allows an adult, often a parent or guardian, to manage the account on behalf of the minor until they reach the age of majority. It is important to consider that specific account types may have different criteria or requirements. For the most accurate and detailed information regarding age requirements and account options, visiting the current Legg Mason website is recommended.
