I have 2 kids (9 and 3) they both carry their dads last name (have the same dad), but he has been absent now going on 2 years and I want to change their last names. I am getting married next year and want the whole family to carry his name. My youngest doesn't even know her biological father and calls my fiance dad. Now my oldest is having problems with the aboandonment from her biological father. She tried to use my maiden name at school cause she wants nothing to do with him or his name and they told she couldn't and she cried all night, and through a long talk with me and my fiance she has come to realize that her father chose not to be there for her and it isn't her fault and just a couple of weeks asked if she could refer to my fiance as her dad. Now to the biological fathers part i have read other threads and couldn't seem to get this answer. He is a wanted felon in the state of texas and I could not reach him if i tried he is so deep in hiding. So contacting him is impossible and even if I did he would never agree to what I want nor would he ever sign anything giving me complete control of the kids. So what do I do in order to change their names, does my fiance have to adopt them in order to change their names to his? That would be ideal but one step at a time. Please help so we can leave the looser behind and have a happy family.
