Ex trying ti falsify court papers what do I do?

K so I told my husband I wanted a divorce the end of February and we seperated. Since then my 2 yr old daughter have moved back home to my mothers house. Tonight my husband meets me after work and gave me these court papers that are filled out by him. In these papers he says that he has our daughter 51% of the time when she is with him on weekends. he also says that I make $17,000 a yr and have only worked for 5 months in almost 5 yrs and that has been since I left him. And I only make $8.65 an hr. He has printed papers saying I will have to pay him child support and that he can claim her on his taxes. He has asked me to sign these and return them before monday. What should I do?
