What happens if you don't sign your DD214 when discharged from the military?

Nothing happens. The signature on the document just says that you had the opportunity to review the document and that it is correct.

It won’t stop you from being discharged, if that is your thought process. I think they put in unavailable for signature. Although, with all the 214s I signed as the certifying official, I don’t recall anyone refusing to sign.

Nothing. Just unavailable for signature. But keep this in mind as I have seen this a lot. By not going in and signing the DD214 to verify that everything is correct. The DD214 will be mailed to the last know address listed. I have seen where DD 214 have been mailed like that to a last known or Home of Record address, that the individual hasn't liked in for a lot of years.

Besides, it's easier to correct the DD 214 while sitting there, then getting it in the mail and you are missing a lot of stuff. then you have to start the DD 215 correction process.
