Legal Data Security

• In delivering legal papers (a process server), often folks do not want to admit they've received them, because not being aware of the proceedings is actually a legitimate defense.  (Technically, court info is public information, but in practice it would be ridiculous to assume everybody is hitting "refresh" on the search features in every possible jurisdiction.)  For example:
• They don't want to admit they're even the person in question.
• They don't want the divorce.
• They don't want to admit they're being sued.
• A judge recently allowed process to be served via Facebook.  (It's easier to leave no forwarding postal address than to switch all your friends on Facebook!)
• In debt collection, a debt collection agency will often be faced with supposed debtors who make some combination of these claims:
• They aren't the debtor in question.  (For example, due to a change of address, or duplicate names.)
  
• There is no such debt.  (For example, due to identity theft at the origin of the debt.)
  
• They paid the debt already.  (For example, because another agency has already collected it, but sold the note anyway.)
• In real estate title insurance, a property seller might not actually own their supposed property, because:
• They already sold it to someone else.  (Double or triple sales, for example due to a previous transaction "falling through" but then completing.)
• They don't have the legal right to sell it.  (For example, due to "winning" the property on a bet, or because they actually own the property next door.)
• The solution is to make "closing" legally binding, and to officially record property ownership in a government property database.  This works because it's easier to globally index property than to globally index people.
