Glad you were able to confirm what country you live in, as it seems you had some doubts.

Anyway, good news, grounds were added to the code in most places in the US for areas around water (kitchen, bathroom, laundry room, etc) back in the late 40s. Grounds on every circuit weren't required until 1960. If your house was built to the code you have a grounded breaker and probably grounds to the boxes in those places. Two-prong outlets were still the standard, though, so the ground might be a separate wire that is only tied to the outside of the box. The only way to tell, if you can't see where the wire is attached, is to do picture related. Use a multimeter or simple tester to check for ground while the circuit is still hot. Test every piece of metal inside the box that you can see and if one has a ground then attach a ground wire to it with a screw. If its a bedroom or something then there might not be any ground at all, though.

If the box is totally ungrounded then see if you can pull the box and check for some ground somewhere in the wall. If the wire was run in metal conduit then that can also be a source of ground. If, after exhausting every method and you still have no ground, then you gotta run a new wire.

If all else fails, do what >>1334637 says with the GFCI outlets.
