As per SEBI guidelines, third party transfers are not permitted. This means you cannot use someone else’s bank account to fund your trading account. Your Arihant account balance should be funded by your own bank account (ie. an account in your name).  

Thus, you cannot add your husband’s bank account to fund your trading. But you know what? If you have a joint bank account with your husband, you can link it to your trading account and use it to transfer funds to your account.
