Online legal documents are a dime a dozen, and you want a fast and convenient place to download free legal forms. You need a contract. There are many places where you can download free legal forms. What you need to be sure of is whether the forms you've got are any good.

I strongly suggest that you use State Specific (forms drafted for your State). You need to know if they apply to your circumstances.

Please Note: No documents or information provided anywhere online for free should be considered legal advice, or intended to replace a formal discussion with a licensed attorney.

You will find disclamers on these free legal form websites such as this one.

Since every legal issue is different, suitable legal counsel should be consulted to advise on and resolve specific matters. The documents on this website are made available as guides only and you use them at your risk.

If you have questions relating to the law, I advise you to seek the services of an attorney. Some communities have lawyers willing to provide limited free advice for persons with low incomes. Talk to the local bar association. Here are two links one is free no attorney, the 2nd link is a legal service, State specific legal documents and attorneys who are legal experts in specific areas of law.
