How do you dissolve a limited liability company business due unethical practices from a partner in a LLC business?

you need to get an injunction

I agree with my colleague that you probably have to get an injunction - an action to stop the other member from taking any additional acts on behalf of the LLC while you sort things out. You are also likely to need to take legal action to resolve your dispute over your ownership and interest in the LLC.

As 50/50 members of an LLC, unless the operating agreement provides otherwise, both you and the other member have the right to enter into contracts on behalf of the LLC and use the LLC bank account for the LLC's business purposes. As 50/50 members, there is no statutory solution if you are deadlocked. In general, members stuck in a deadlock have the following 3 options:

1. The members can agree to dissolve the LLC: Based on the actions of the other member, I assume that he/she will not agree to dissolving the LLC, liquidate and split the remaining assets after winding up the LLC's business;

2. One member can buy the other member's interest in the LLC: Again, I assume the other member will not be willing to buy you out and/or pay the fair market value for your interest;

3. You have to resort to a law suit to either determine what is the reasonable course of action or proceed with a judicial dissolution of the LLC.

Unfortunately, it looks as though you and the other member disagree as to how to run the business. Rather than dealing with this deadlock, the other member began taking steps to "remove" you as a member. The injunction will stop the member from further draining the LLC of its funds and taking steps to "remove" you, and a lawsuit can force the issue of dissolution and/or a buyout of your interests.
