If you live in the Douglas or Sarpy county, you could go to the records office and ask the staff to help you do some research on the property's title. They should be able to assist you in finding liens on the property.
You could also contact a title company (check the phone book) and ask for a title search. This may cost
around $75 or so.
If you are planning to purchase the property you can make it subject to the owner giving you clear and marketable title. You should ask the seller to give you a general warranty deed (this will give you the greatest assurance of title) and also ask for title insurance (look into the expanded policy to increase your protection).
You are wise in asking the question you did. Before one takes title to any real estate, a thorough check of the title should be made.
Hope this helps some.
