If a rejected asylum seeker does not want to leave Denmark voluntarily, the immigration authorities can employ various methods to "motivate" them to accept the refusal and cooperate regarding their departure (so-called motivational measures). The Danish Return Agency takes care of voluntary return journeys, while the police can deport rejected asylum seekers by force.
It is common for rejected asylum seekers to be accommodated at one of the departure centers, Kærshovedgård or Sjælsmark. Here they will not receive pocket money or cash payments to buy their own food, but instead take meals in the canteen. Families with children are accommodated at Avnstrup.
It is the immigration authorities that assess whether a rejected asylum seeker is cooperating regarding their deportation. The immigration authorities can, for example, assess that a rejected asylum seeker is not cooperating regarding their deportation if they do not sign the return agreement. The same applies if, for example, a rejected asylum seeker does not want to help get their identity established, does not want to show up at the embassy or does not otherwise try to obtain the documents that the immigration authorities request.
The immigration authorities can also decide that a rejected asylum seeker be detained for a period until they either decide to cooperate or the police can make a deportation by force.
If an asylum seeker is deprived of their liberty, they will be assigned a lawyer to represent them. It is always a court that decides whether the requirements for deprivation of liberty have been met, e.g. there is a requirement that the authorities actively work on the deportation and that the deportation is realistic in the near future.
