My wife had a change of companies who manage their stock portfolio and she needed to make a change to the new company. the choices were transfer your funds over to the new company or get a check cut to you and they send it in the mail. she filled out the paperwork to have the funds sent over to the new company handling the 401 K. needless to say we got a check for the whole amount of her previous 401 B retirement in the mail. she called the company and they said all she can do is mail the heck to them in their office ( which is a couple of states away ) I know I do not feel comfortable send a very large check in the mail, how about FedEx with shipping and signature confirmation ? can not find anything on their website to see how much it could be insured for to make sure the amount would be covered. hate to ask the clerks what we like to insure the envelope for as that may make somebody get some sticky fingers. the check is made out to the new 401K company and my wife. thanks for all for the suggestions. wish they had a local office as I would rather hand the check to an employee.
