Legal Question in Family Law in Georgia

First of all none of us have read the originals to know if they are valid (I should mention that in Georgia, unless you have a large complex estate, a trust is generally overkill and most people do fine with a will alone). Meet with a lawyer to review and update them as needed. That is the important question you didn't ask.

When you sign a new "copy" of a will, that revokes the earlier original. So your "copy" would then be no good.

Wills and the like should be kept in a safe place and not with you at home. A safety deposit box that both you and he can access is perfect.

I would not mess around with signing copies. That could just complicate things. Send him copies and make sure he has access to the originals.
