Running air handler condensate drain into sump?
Well, i don't really see an issue with this since the condensate water is basically distilled water with neutral PH. The legal issue with it may be due to furnace condensate water which contains carbonic acid. Using a neutralizer will take away almost all the acidity, however some municipalities still don't allow either condensate water to be piped to the sump to account for idiocy.

One possible solution, you can get a condensate pump, and have it pump the water though a tube to any sink, or drain you can run the tube to. The only downside is the sound of the pump turning on ever now and then.
