My grandmother was called by our neighbour inorder for "her" to get a personal loan and she wanted my grandmother to be the guarantee. They both went to the bank and my grandmother has no legal knowledge at all. She took a personal loan in grandmother's name andmy grandmother signed all the paperworks ( she was muddled through the encounter and had no idea what was actually going on ) . Later the bank officials called us because of no repayment and that's how we came to know about this matter . Is there anything we can do like sue her for fraud or something , inorder to get rid of this mess
