My husband might have a child with another woman. Will my income be included in the amount of child support? Will buying a home in the future be affected? How old does the child have to be in order to spend time, overnight or daily, with us. What are our rights? What claims can she make on us? We are willing to pay the child support and extra as needed. What can we claim on our income tax? Can we ''force'' her to take a paternity test prior to birth? We want to place the child on insurance ASAP.
