yes this is true. I am not sure if you have to do corporate minutes and resolutions for an LLC, but in my case. When we had to open the bank account I made sure that "Just for Audit purposes" two of us have to sing the check in order to be valid. This helps establish a mutual agreement and if the other person down the road decides to say he wasn`t aware... Well his singature proves different.
Good suggestions, internal control is definately something to keep track of.
Typically LLCs do not need minutes or resolutions, but a bank may require them when opening the account.
Also note that banks do not (always) monitor all checks to verify that there are two signatures. The only time they would normally catch this is if it was actually presented to a teller in a branch. Most banks provide a liability waiver that you must sign on this subject. Nonetheless, it is a good practice if only for internal control purposes!
