To transfer a pension plan from another bank to BBVA, you must be a bank customer.
If you're already a customer, the next step is to open a pension plan with BBVA and request to transfer the other plan. At this point, you have to indicate whether you wish to transfer all the capital (total transfer) or only a part (partial transfer).
From then on, BBVA will handle the rest of the operation. The entire process usually takes between 5 and 10 business days, provided it involves individual pension plans.
