Transfer of Entitlement
Post 9/11 GI Bill allows service members to transfer all or some benefits to dependents (spouse, children, or combination of spouse and children).
To be eligible to transfer benefits, the service member must have at least six years of service and commit to an additional four years. The request to transfer benefits must be completed while an active member of the Armed Forces.
