I've received data from a contractor, they have provided it in both MapInfo tab file and shp file format. When I check the regions in MapInfo using the Check Regions tool one overlap between two regions is identified.

When I check the shp file in ArcGis using the Intersects tool it identifies around thirty polygons that intersect.

I've tried translating the MapInfo data again using the Universal Translator and QGIS but the resulting shp files all have the same intersects as the first.

Ultimately I need the data in shp file format, can anyone suggest a solution that doesn't involve cleaning the data again in Arc (I'm expecting a much larger batch of data through and don't want to have the same problem)?

Thanks
