Unregistered Will with two diffrent signature

Its not very clear.. I mean am unable to see the difference. Well if its totally different then hyou may have trouble on the probate in case it is contested. So its advisable to get the will registered in case its possible to do so now.

IN UR CASE IF THE SIGNATURE IS SAME PERSON WHY SHOULD U AFRAID .IF ANY BODY REVOKING THE WILL THEN SIGHNATURE IS VERIFY BY SIGNATURE EXPERT OR HANDWRITING EXPERT .PROVE THAT THE SIGHNATURE IS SAME BUT IN UR WILL THE SECOND WITNESS SIGNATURE IS NOT CLEAR .
