If Defendant responded to discovery request with objections and I file motion to compel, when court will support the Defendant that documents are not admissible? Defendant claims repaying me and giving me extra money so that I owe her. Is her tax return and proof of income relevant to discovery.Some answers indicate that proof of income is not relevant. She is claiming repaying me in form of cash in excess of amount owed wihout bank records. Does she need to prove that she had the money to repay in form of earned wages or bank saving? What is purpose of discovery? On my behalf, I have tangible records of giving her the money.
