Lis pendens is Latin for "suit pending."[1] This may refer to any pending lawsuit or to a specific situation with a public notice of litigation that has been recorded in the same location where the title of real property has been recorded. This notice secures a plaintiff's claim on the property so that the sale, mortgage, or encumbrance of the property will not diminish plaintiff's rights to the property, should the plaintiff prevail in its case. In some jurisdictions, when the notice is properly recorded, lis pendens is considered constructive notice to the other litigants or other unrecorded or subordinate lienholders. The term is sometimes abbreviated as "lis pend".

In current practice, a lis pendens is a written notice that a lawsuit has been filed concerning real estate, involving either the title to the property or a claimed ownership interest in it. The notice is usually filed in the county land records office. Recording a lis pendens against a piece of property alerts a potential purchaser or lender that the property’s title is in question, which makes the property less attractive to a buyer or lender. After the notice is filed, anyone who nevertheless purchases the land or property described in the notice takes subject to the ultimate decision of the lawsuit.

A foreclosure will wipe out a lis pendens, unless the mortgage or other lien which is being foreclosed was created after the suit was filed.
