A limited warranty deed is used for Minnesota real estate transactions where the grantor agrees to guarantee that, during the time of ownership, the grantor did nothing to encumber the property. The deed also passes after-acquired title (any future rights the grantor gains to the same land transferred by the deed).
By excluding assessments from the covenants of title, the grantor alerts the grantee to the fact that one or more outstanding assessment liens and any associated interest may still be attached to the title.
