Someone wrote me a personal check using a starter check. Can I use it to open a bank account, or cash it at their bank?
The only issue I can foresee with opening an account with the check is that it does not have the name of the person who wrote you the check at the top. Other than that, it is a legitimate check. As you would most likely be opening the account in person and the check is hopefully valid, then you should not have an issue using the check.
If the bank does refuse to use the check, then you should either have the person who wrote it reissue it with a normal personal check/money order or go to the bank that they use and have them cash it and then take it to the bank that you would be opening an account with and use the cash to open an account.
