What are the documents required to claim HRA?

You are not required to submit any document to the Income-tax department for claiming HRA exemption. However, you need to update your employer at the start of the financial year about your rental status and submit proofs in the form of rent receipts and rent agreement to your employer before the end of the financial year. This will help you get exemption in your form-16 and you can avoid further hassles during your Income-tax return filing.
