a good solicitor would deal with this case, you can sell your share legally but you must inform your partner and legally you should offer her to buy, if not you can sell it legally by auction by turkish court
better if you serach for uk based turkish mortagges if yo uare from uk as they know what they re doing, also denizbank in turkey has mortgages for foreigners too
the villages are always an issue, but you should not have a problem selling as in the worst case the buyer can open a limited company and register it on the companies name
i think i know what you are talking about as recently some of my friends had the same issue, if your property is being connected to mains sewege the council is asking for connection charge which you have to pay,
