Question by Jacques (Royan): “My bank accepted a check that wore my falsified signature. Is his responsibility engaged?”
Your bank has engaged its responsibility. According to the elements of your question, it appears that the check Currently entered the classification of “false checks”: you have not signed it. In this case, devoid of the signing of the shooter which is one of the conditions of validity of payment title, the check is not valid. And this also applies when the signature is perfectly imitated. According to the case law in force, the bank is wrong if it has paid it. Which seems to be the case for you.
Contact your bank’s customer service without delay to find a way out of this illegal operation. When you have exhausted all the appeals, you can enter the banking mediator.
Note that if you had signed the check but the amount or its order was modified, it would have been classified “falsified check”. In this case, your bank would have had its responsibility engaged only if the falsification had been coarse and visible to the naked eye.
