Encourage & make clearer to signer they can "draw" their own signature. Reducing risk of challenges saying "That's not my signature" etc.
Just concerned and as another way to avoid someone "Trying it on".
If someone breaks a contract then doubt the legality of these then of course it's a hassle anyway. If the signer opts for the pre-drawn signature then surely this is going to pave the way for more difficult customer to say "That's my signature" etc. If they were encouraged to draw it as the first option then although it is all Legal it will actually appear more legal to signers. Hopefully stopping any challenges before they start.
