Depends what the relation is.

If it's a multipolygon, the JOSM validator will handle it. Difficult geometry problems can be sorted out with te OSM Inspector's multipolygon view.

If it's a route relation, you can order the elements in JOSM's relation editor and see if they connect, but this only works if the route is the same in both directions. The Relation Analyzer automates this process for a saved relation.

If your route relation uses directional roles (north for ways that carry only northbound traffic, etc.; common in the US but probably not elsewhere), you can use Nakor's tool. I know of no tool that will handle the more common forward/backward roles.

If it's a turn restriction, JOSM (with the restriction plugin) will check it. You can also use the Restriction Analyser, which may find errors that JOSM doesn't (and vice versa).

There's also Relation Check, which I haven't used.

There is also the Analyseur de Relation which analyzes relations for gaps and intersections - see http://analyser.openstreetmap.fr/cgi-bin/index.py
