Can an ex-wife come back for more child support because of former husband remarried?

What is the name of your state? Illinois

I am married to a man that has to pay child support. I would like to change my name to his last name but was told that in doing so his ex can come back asking for more child support because there are now two incomes. We plan on having seperate checking accounts and filing seperate in our taxes. I was told that as long as I have his last name, his ex can come back and ask for more money. Also the same goes with buying a house together. Can his ex come back and claim the house?

His ex cannot go after your income for support. You are not liable to support a child you did not conceive.

However, his support could be increased or decreased based on your marriage. It could be increased because there is now more money in the household to help support the household. It could be lowered because you will be in a higher tax bracket.

If you have a house in your name only, she cannot touch it. If you have a house in joint tenancy, if he falls behind in support, she could ask that a lein be placed on his 1/2 of the equity, but not your 1/2.

She's blowing smoke, and it has nothing to do with your name change. If this happend with frequency, people would not get remarried until support woes were taken care of.
