From time to time, clients come into our office with the following scenario: "I have been married to my husband for 5 years. We have no children together. Our relationship has been up and down, and we were separated for about 3 months last year. During that time, I had a relationship with another man and I became pregnant. I was not sexually active with my husband at the time married too young. However, my husband and I reconciled so I ended it with the other man. My husband believes that our son is his own. I have not told my husband about the other man. Now, we are having problems again and I have filed for divorce. I want to legally establish who the father of my son is and I want to tell my husband the truth about our son. What can I do"As a divorce attorney, my response is: First of all, your husband is presumed to be the father under Texas Family Code (TFC)
