First of all, remember that the vast majority have no problems. It's just that urban myths and reality conspire to make everyone fear the worst. Yes, there are some horrorr stories, but if you play fair and are upfront, on balance you can expect things to go reasonably smoothly. The HR folks have been doing this for years and there is well practised process and procedure.
I would advise something like this:
Before resigning or breathing a word to anyone:
1. You might want to send your family packing off home (personal choice)
2. Pay off your credit cards if you can
3. Definitely take virtually everything you can afford out of your bank account. Keep what you need under the mattress and change the rest into hard currency. (QR can and do stop people's bank accounts, with no particular rhyme or reason)
Then resign, in a polite and professional written note, explaining you are leaving 'for familly reasons' (wife has had enough, kids need to go to other schools etc)
Deep breath.
4. Sell you car(s) and rent short term
5. Sell as much of your stuff as you can. It will go quickly.
6. Arrange removals (again there are several very good and efficient companies)
7. If not in company house, tell your landlord. It may help to smooth things if you can bring him another tenant to take over the property. HR may be able to help here by hooking you up with new arrivals
8. Few days before leaving arrange for electricity guy to visit and cut you off on day you quit the premises (if not company house). Surprisingly this is about the most efficient part of the whole thing. Disconnection and cash deposit refund can be done within same morning.
etc etc
Hope that gives some help
