Joint savings accounts can be created and shared by any two individuals eligible for an Atmos account. To be eligible for an Atmos account, individuals need to be at least 18 years of age, and be a valid and legal resident of the United States with a government issued Social Security Number and ID.
Adding your child to a joint account would give them access and some control over the funds in that account. This can be a practical step for managing finances together, especially if it involves shared expenses or if you want to assist them in managing their finances independently.
