The best way is to convert this shape file to file-geodatabase and build the topology in ArcGIS for "Must Not Gaps" and "Must Not Overlap".
Important thing in building topology is cluster tolerance. This is tolerance in which topology will remove/fix errors automatically after validating. So you should select this tolerance very carefully as big values can ...

Data for US federal lands can be found through the GeoCommunicator site. However, it does not cover the entire country.
For private parcels data are much less accessible. For these data you generally have to go to the GIS department for the county, or if there isn't one you may even have to digitize paper maps/plats.
Some private companies, such as ...

If you have an ArcEditor or ArcInfo license, you can use ArcGIS' Parcel Fabric tool.
In the parcel fabric, parcels can be divided by area to create new
parcels. Using the parcel division tool, you can divide parcels using
the following area-based division methods:
In equal widths
By proportional area
Into equal areas
I assume you ...

Report All website has a large data archive of parcel data per state/county (some states and counties are not included). You can purchase data per county via shapefile, kml, or excel.

It sounds like what you want to do is write an expression for your label instead of simply choosing a "Label" field.
On the Label tab of the Layer Properties:
Choose the "Expression" button:
Here, you can see that I have entered the following: "Parcel Number = " & [APN]
The first part of this: "Parcel Number = ", is simply a text string
The second ...

Get Spatial's answer above is probably the preferred method, in that it directly addresses labeling. If, however, you have some reason for wanting this concatenated string of two fields to be persistent in your data source, you could add a new add a field to your table and create the value there and use the new field as your label.
Open the table.
Select ...

Another alternative would be to use the Eliminate (Data Management) tool in Arc. However, I agree with iRfAn and Roy that topology rules would be the best practice in your case if you are looking for a long term solution.

Honestly, you sound like just the kind of person Esri developed parcel fabrics for. I would recommend watching (or at least skimming) this hour-long webinar to see just what you can (and can't) do with parcel fabrics.

I think this is an excellent question and an ideal candidate for an ArcGIS Idea (if there is not already one).
The Online Help for Multipart Polygons says (with my bolding):
Keep in mind that parts in a multipart polygon are spatially
separated. They can touch each other at vertices, but they cannot
share edges or overlap. When you are sketching a ...

There is an Esri Technical Article on this (don't be put off by it only going up to ArcGIS 9.3.1 because it still applies at 10.1).
Try the instructions there and, if you have any problems, perhaps edit your question to describe the steps you have done and where you may need further assistance.
A quick description is:

Maponics would be it. I used to update the data they now use and it is the best in class, historicaly it was tele atlas data 'multinet', maponics spun off for the uses you describe.
Nationwide polygon data would be very expensive i expect. a way to create a cheaper and much less accurate coverage would be use tiger data and polygonize by zipcode.

use the make query tool in data management.
arcgis resource center says it like this.
I just saw this 1:M tip on arcgis support website.
There does seem to be some other usable information here.

I would think using intersects would work. Let's say pid is your parcel ids
SELECT p1.pid, array_agg(b2.pid) As neighbors
FROM parcels As p1 INNER JOIN parcels As b2 ON ST_Intersects(p1.geom, b2.geom)
WHERE p1.pid != b2.pid
GROUP BY p1.pid
If you would prefer a string instead of an array and are using PostgreSQL 9.0+, you can use
string_agg(b2.pid, ...

I have tried to make the possible solution simpler but it seems to be the only solution, but i like to have any suggestions .
from polygons make lines (arcs) => lines.
buffer polygons with 3m => polygon_buffer.
make spatial join between polygon_buffer and lines with "one to many" , to get all the polygons touching the lines => sp_lines_buffer.
for every ...
