So I feel like I'm not really understanding how block chain will work for title searches.  From what I've read, as each document is recorded, it's applied to that property, and the chain and liens are guaranteed?  If that's the case, I'm wondering how a search I've done recently would be handled by block chain.

John and Patricia own a parcel tenants by the entirety w/survivorship.  The county vacates a parcel to them that the county just "adds" to this parcel, so it's one parcel with one address and one assessment, but two legal descriptions.  John dies.  Patricia conveys both parcels to her daughter Melissa and husband Paul, and Patricia reserves a life estate.  Melissa and Paul divorce.  Melissa, Paul and Patricia convey the property to Melissa and Patricia as joint tenants with survivorship.  Patricia dies. Melissa records a real estate affidavit claiming her interest, and listing Patricia's son of unknown address as an heir. No will is recorded.  Seven days later the son shows up and records a will conveying all property to himself.  . 

And Melissa has been married four times, so some deeds have her with a different last name and she has taken mortgages out by each one of those lasts names, not to mention the judgments against her various names.

AND just to make it even more interesting, every deed and deed of trust recorded has either the wrong address, the wrong Tax ID, a legal description with errors, or only one of the parcels, not to mention inaccurate being clauses. 

So. How does block chain work?
