First, if you give an answer before a judge in good faith with all the knowledge you have you probably won't see trouble. To find out if your case is still open call your bankruptcy attorney, or call the Court (with your case number) and ask if the case has been discharged or dismissed. It probably has.
28 years is probably beyond most statutes of limitations. This means that it's too late for anyone to sue you. But, if you feel you need help call either the Volunteer Lawyer Network or the Southern Minnesota Regional Legal Services.
I agree with Attorney Cobb. However, in cases like this proper procedure is more important than the final result. If you do not follow proper procedure you may be stuck with an entity that has nothing but is still a taxable entity. So, you should retain an attorney.
I agree with my colleague. Furthermore, I am a Minnesota business attorney, tax attorney and C.P.A. The L.L.C. which owns the property would file its own return and report rental income, and expenses, on such return, not your personal 1040's Schedule E. What entity is your business operating in? You may want to consider forming a new entity for the business in addition to the property owning LLC. You can call me at 651-434-7590.
