Whenever any person shall commence a suit, action, attachment, or other proceeding, whether at law or in equity, to enforce any lien upon, right to, or interest in designated real estate, the pendency of such suit, action, attachment or other proceeding shall not operate as constructive notice thereof to any pendente lite purchaser or encumbrancer of such real estate for a valuable consideration and without notice, until such person shall file for recordation with the clerk of the county court of each county where the real estate sought to be affected is situated, a memorandum or notice of the pendency of such suit, action, attachment or other proceeding, stating the title of the cause, the court in which it is pending, the names of all the parties to such proceeding, a description of the real estate to be affected, the nature of the lien, right or interest sought to be enforced against the same, and name of the person whose estate therein is intended to be affected: Provided, however, That where the lien, right or interest asserted is based upon a judgment, decree, claim, contract or other instrument which has been docketed or recorded according to law in the office of the clerk of the county court of the county wherein the real estate is situated, and has thus become a matter of public record, the failure to file the notice herein mentioned shall not operate to defeat the enforcement of such lien, right or interest in the real estate as against such pendente lite purchaser or encumbrancer.

The clerk of every such county court shall, without delay, record such memorandum or notice in the "lis pendens record," note upon the record the day and hour when such notice was filed for recordation, and index the same in the names of the parties.
