A claim which the legislation requires to be made on a 'form approved by the Commission' or 'in accordance with a form approved by the Commission' means that the claim must meet certain requirements, e.g. must be in writing, provide specific information, or evidence to support the claim. It does not mean the claim needs to be made on a special or official DVA form. However, where a DVA form is available it is preferable that it be used to ensure that all the information required for a proper claim to be made is provided.
