I’m not entirely sure… At the very least you would be able to immediately collect unemployment (~12.000 DKK if you don’t have kids, ~16.000 DKK if you have kids), and if you’re in an “a-kasse” you would be able to collect up to 90% of your old salary.

I’m pretty sure thought, that anyone who ran away with the bank account would pretty much have to leave the country, as otherwise they would be apprehended by police, personal belongings would be repossessed, and they would not be allowed to start a new business.
