Yes. You will need a signature stamp to place your signature on your RAVBM envelope or declaration. You can authorize someone to design the signature that you will use for your stamp. However, once you have your signature stamp, you will need to re-register using your stamp in the presence of a county election official, if you have not done so already. When using your stamp on your RAVBM envelope or declaration, remember to have someone “witness” your stamp as described above.
