Since the LLC is 50/50, do I only send his half or do I have to send all of it?

My husband and I live and own an LLC. He recently received an order for court in another state for child support for his first child. The LLC is owned 50/50. They are requesting he bring in his proof of income such as taxes, paystubs and etc. We are taxi fleet owners. He does not get a 1099 or W2. I filed a 1065, Schedule C, SE, 4797, 8965, EIC, 8824. One for him and one for myself. I also I have full time employment and received a W2 form and each one of us received a Schedule K-1. I don't believe I should have to provide my income information for his child support obligation, but we did file jointly. What is the right way to go about this?
