Here's the story. My husband may have fathered a daughter before we ever met. He was not named on the birth certificate and the biological mother had relations with other men during the same time frame. The girl was legally adopted by another married couple. She made contact with the birth mother a few years ago. The birth mother gave her my husbands name. She contacted me some 8 years ago. I gave my husband all of the information, but he had no desire to meet with her. Fast forward to this past year. She contacted our daughter and is saying she could force my husband to take a DNA test. My question is, is this true and if she were proven to be his biological child, would she have any claims to our estate?
