If occupation contract fraud has been proven but the contract holder would be entitled to be housed had they not completed the fraud, a request backed with any relevant evidence should be submitted to the CHM to assess whether they can keep the occupation contract.
If the request is rejected, or it is reasonable to take back the occupation contract due to the fraud committed, an RHW23 form can be served based on breach of contract Section 157, and an application made to court for possession.
Further considerations
In extreme fraud cases, it may be sufficient and reasonable to report the fraud to Gwent Police for criminal action to be taken.
