Child Support, Paternity Tests, and Liability Through Marriage
Your husband had 5 years to contest paternity regarding the two children. Since that window has come and gone, he is stuck paying child support.
You are not and never will be responsible for his child support. That is and will remain his sole debt. However, if you have jointly titled assets such as bank accounts or a house, the X could obtain a judgment and garnish the bank account or lien the house.
Your husband’s name must not be on any of your assets. If it is, you are at risk.
You should file an amended application for marriage license which states your husband’s true social security number. You marriage is still valid.
