The EU's told Britain it'll have to agree its Brexit bill before talks can start on a trade deal.
Draft guidelines have been presented to the other 27 member states as some EU leaders gather in Malta ahead of Brexit negotiations.
The guidelines refer to the "unique circumstances" relating to Ireland, they suggest that the Common Travel Area with the UK be maintained and recognised by Europe and that any solution to avoid returning to a hard border with the north would have to adhere to all EU rules.
The President of the European Council has also warned it's of crucial importance to support the Northern Ireland peace process during Brexit negotiations.
Donald Tusk also says sufficient progress on the UK's withdrawal from the EU must be made BEFORE any new trade deal.
