What the titleholder field really tells you
Names on parcels near Des Moines are not always a person: land near Grenville may be held by a trust, an LLC, a partnership or an estate. Compare the mailing address with the location: a management company in the field frequently means rental or investment ground in Union County. Owner names on the county map show the titleholder as of the last roll, so a recent sale near Grenville may not appear yet.
Confirming ownership with the deed
To confirm who owns land near Des Moines, request the latest deed from the county's recording office. If the Union County record lists no document number, search the grantor-grantee index by the owner's name.

Joint owners and tax status in Union County
For land near Hayden, a record listing several family members frequently means inherited ground with more than one decision-maker. Tax status can help, too: the county treasurer or tax office displays if taxes on a parcel near Clayton are current.
