Do I leave Jacob's social security card unsigned, or do I sign it? When I was young parents didn't have to have social security numbers to claim children on their taxes, so I didn't get a card until I knew how to sign my name.
Well since dd's handwriting is so bad - I am not going to have her sign her until you can actually read her writing - she will be 12 in May - and could care less about her handwriting now
Just leave it unsigned. There is really no need to have it signed at this time. Like someone else stated when he goes for his first job then give it to him to sign and use for an I-9 document.
I signed both of my kids SS cards. My mom did mine when I was younger so I just followed what she had done. Really never thought to leave it blank. I guess when they get ready to turn sixteen I could order new ones and then have them sign their own.
