Yes. If you left a relationship where there was domestic violence, you may not have all of your paperwork, and it might not be safe for you to try to get it.
DTA can ask for proof of certain facts to make sure that you qualify for welfare.
Your worker should help you figure out how to get the documents safely. Your worker also should help you get the documents if you are having trouble getting them on your own. For every fact that you need to prove, there are different ways to prove it. For some proofs, your worker should accept a written statement from you, called a “self-declaration,” if you can't get other types of documents.
Tell your DTA worker if you are having trouble getting the proofs that he or she has asked for. The law says that your worker must help you.
