The Housing Executive has a legal responsibility to help people who pass the 4 homelessness tests.  The tests look at whether you are homeless, why you are homeless, whether you're entitled to help and whether you're in greater need of help than other people. 

If the Housing Executive decides you've failed one or more of these tests you have a legal right to ask that this decision be reviewed.  There are strict time limits though, so you need to get advice and act quickly if you're going to challenge the Housing Executive's decision.
