Thank you for your consent.
No, I do not see opening a commercial lease under your name is XXXXX XXXXX is illegal or can get you into trouble. An LLC by itself, if it breaches a contract
or breaks the law, and if you are a principal owner in the company, you may then be held liable, but not for anything else.
In terms of a lock out--if the lease on the premises is under your name, you are free to remove him from the premises and he cannot lock you out. You are the lessee, not him--if he chooses to lock you out, you are free to forcibly re-enter (that is, use a lock cutter), remove his items and him as a trespasser, and lock him out of the business.
The database is jointly owned meaning that one should not be able to lock out the other, but that is based on how the DB is actually written and coded. If he locked you out, consider filing a lawsuit against him for tortious interference with your business interest and sue him for damages that you are incuring.
hope that helps.
