Council tax summons UK?

Continue to try to speak to the council tax enforcement officer (the one who appears in court over these matters). He or she exercises considerable discretion, especially where costs are concerned. If you can't get through, get to court early and have a word with him/her. The vast majority of these summonses are resolved out of court. If you reach some kind of amicable arrangement, then the summons can be withdrawn or, failing that, adjourned pending a mutually acceptable settlement.
