Evidence needs to be from a third party i.e. not from family, friends or anyone personally linked to you. It needs to signed, dated and on headed paper. Evidence should come from recognized practitioners such as doctors, counsellors, therapists etc.
The evidence should ideally be contemporary i.e. from the time of the assessment or from a professional who saw you at around that time.
The evidence needs to be in English or be translated into English. It needs to be clear who carried out the translation. It is better if it is done by a third party.
