What to do the last few days before you leave?

Return any remaining library books.
Redeem savings stamps from local retailers and online providers, insofar as you can no longer use them in or from abroad.
Redeem last-minute gift cards (as a surprise, have your children use them to finance their last pre-departure purchases or presents).
Inform the neighbors (well in advance) on which day you are really going to move, if relevant: the moving van can hinder you somewhat.
Remove fixed lights, possibly remove the satellite dish from the roof.
Get some simple meals, coffee, tea, soft drinks etc. in the house for the evening before the move and on moving day itself.
Make a last appointment with the municipal waste disposal for remaining bulky waste.
Secure the washer drum guard.
Unpack and pack perennial garden plants (of course if the season is suitable and you want to take them with you).
Empty the environmental box at the municipal depot.
Defrost and clean the refrigerator.
If necessary, screw the nameplate from the door.
Keep a spot free in the immediate vicinity of your house for the moving van (about 10 meters) And arrange this in advance-if possible-at your new address.
Study (again) the procedure for reporting moving damage and check the conditions of your mover (so you know on the day of moving and arrival how and within what time to act)
Arrange -if you haven't already done so- a supply of passport photos of all family members; you will undoubtedly need these when arranging all kinds of administrative matters after arrival abroad.
Make the last copies and scans of all relevant official documents of all family members; put digital files in a protected online environment (document storage); keep one set in your hand luggage and one set in the removal van or check-in luggage.
