I am interesting in forming an llc with a partner

In order to form an LLC, you must draft a certificate of formation, pursuant to the statutory requirements.  You should have an operating agreement that sets forth the rights responsibilities and liabilities of the various members, including capital contributions.  Thereafter, you must file annual reports and pain annual fee to the Secretary of State's office.  Check the Secretary of State's website to see if there are forms available.  If not, or if the forms are insufficient to answer all your questions, I strongly recommend that you consult with counsel.  Not only will this help you get it right, but if there is a mistake made in the formation, you at least have some recourse to get it fixed.
