My wife had the child with another man, but our son knows me and considers me to be his dad. Will I pay child support for him?
In Texas (where I practice), a man becomes a father if his paternity is presumed. There are five ways to create a presumption of paternity:
1) The man is married to the child's mother, and the child is born during the marriage;
2) The man was married to the child's mother, and the child is born within 300 days after the marriage ended;
3) The man married the child's mother before the birth of the child in apparent compliance with the law, and the child is born during the marriage or within 300 days after the marriage ended;
4) The man married the child's mother after the birth of the child in apparent compliance with the law, he voluntarily asserted his paternity of the child, and (a) the assertion is in a record filed with the BVS, (b) he is voluntarily named as the child’s father on the child’s birth certificate, or (c) he promised in a record to support the child as his own; or
5) The man continuously lived in the same household with the child during the first two years of the child's life, and he represented to others that the child was his own.
If you are not the presumed father of the child, you are not likely liable for child support unless you have adopted the child. In other words, it sounds like you do not have a legal parent-child relationship.
Thus, depending on the specific facts of your case, you may not be under a duty to support your soon-to-be ex-wife’s child.
