Re: DNA Test Proves Legal Father's Nonpaternity, But Biological Father is Deceased
If you'd like to include the child in your will, you can do so right now, without court intervention. However, after 8 years, it's MUCH too late for the legal father of this child to dispute paternity and your son is not around to establish paternity. She can't just take someone off the birth certificate, it doesn't work that way and since your son is not this child's legal father, she cannot collect social security benefits for the child.
Sorry for your loss.
If you wanted babies all to yourself, you should have created them by yourself. Until you do that, children have the right to BOTH parents, especially since you found them suitable to procreate with.
