Zombie Title: A real estate title that has stayed with the owner of a residential property after the mortgage lender has begun a foreclosure process (making the owner move out to enable sale of the property) but then cancelled the foreclosure process. The lender is not required to notify the owner of the cancellation, who is therefore often unaware of the obligations associated with continued ownership (which does not change until someone else's name is on the title), such as payment of local taxes, upkeep of the property in accordance with local bylaws, and all other costs and responsibilities of homeownership. The prevalence of zombie titles greatly increased in the United States following the financial crisis of 2007–2008. To prevent this, homeowners should make sure their foreclosure process is completed and the title is legally transfers to someone else.
