Legal advice on Business bankruptcy

Fleet rent a car in Zagreb, Croatia has gone out of business (bankruptcy). I'm due to return the car at the airport at the end of January, 2019. No one works there any more and the same for there location in the city. The phone lines have been disconnected and their website is no longer operating. If the airport security won't except the car, what would you suggest I do with it as I have a flight back to Canada to catch.

I want to file for personal and business bankruptcy today. Is it considered fraud if I open another company in the same location and perform the same operations but under a different name?

I am trying to file a bankruptcy for my small livery business and also need help in getting rid of money that I owe to IRS chicago. So technically it will be both personal and business bankruptcy together.

This is a small business that has run three Adult Foster Care homes for 47 years. The corporation papers have not ever been updated and two of the three owners have passed away. (I do not know if this makes a difference or not) Long story short, a daughter, and daughter-in-law have been operating the business. The sole person left on the corporate papers, Judy, lives in Florida. The business operates in Michigan. The business has been losing money for a few years and frankly has drained Judy financially as well. It is to the point where they do not know how they are going to pay their staff. Credit cards and lines of credit are maxed out. How does a company like this begin a shut down? Is bankruptcy an option? Please help. Thank you.
