how to get title insurance on a missouri tax sale property that only has a collectors deed?

I live in Washington State but the procedure should be the same nationwide. The process we go through here is called a “quiet title action”. It is used whenever there is a cloud on title that can not easily be cleared up any other way. When you purchase a property at auction, you are not guaranteed there are no other lienholders on title. A quiet title action is a fairly short and simple court proceedure but I would recommend using an attorney. This is how it works in a nutshell: Your attorney starts the motion to quiet the title, then has to make it publicly known (usually through newspaper publishing), that you are stating your claim as sole and legal owner. If anyone has any claim whatsoever, on the property in question, they must respond and prove their claim in the time allotted. After the time allowed, you simply make a court appearance and if no one can establish a claim, the judge will quiet the old title and write a new deed.
It is actually a fairly simple and painless process. Here, the cost is around a couple of grand but you might want to call an attorney to get a quote. Good luck!
