If you seek advice from a legal Turkish company, you may be told what have in the past. Unless you are in a complex of maybe 8 apts or more, to set up a comittee and take any non payer to court, it could well cost more (as well as a lot of hassle), compared to the remaining owners paying a non payers share. Unfair we know, but this was the advice I was given, just in case we had any problems with a non payer, but for us, we are lucky and have no problems.....as yet.
