  • Ben Smith says:

    The name I am looking to register was already registered in CT. But the current status of the LLC is shown as “DISSOLVED”. Does that mean I can register this name?

  • Meredith Karter says:

    Provided the business was *dissolved* properly, you can go ahead use the same name for your LLC.

    You may ask what do you mean by dissolved properly, well there is no simple way to determine that. I would suggest you to consult an attorney to verify this for you.
