Some one loan me money for doing business together the agreement was verbal but the business fail and I lost the money he file

You should file a proper legal response to the lawsuit and assert all available defenses/objections. I recommend you hire an attorney to ensure you put forth a good defense. Now might also be a good time to consider filing bankruptcy. Use the Find A Lawyer tab on this website to get a list of bankruptcy attorneys near you and make some phone calls.

Either get a lawyer to help, or file a response to the suit within the time frame.
