* Unless your fiance sprung the fact he had a daughter on you at the last minute then you should be able to handle this. If he didn't tell you about having a daughter then he probably was fearful you wouldn't be able to handle this information. You did not state if the mother has custody; he has full custody or it's joint custody. If you love him it shouldn't make a difference. One day you will have children of your own.
not if you are the biological parent
No. That is her fiance, because of their relationship he can not be her legal guardian.
There is no mention to who had legal custody of Treyvon Martin. However, it has been said that he lived with his father and his father's fiance for several years.
If your "fiance" has a wife in Texas he must go back to Texas to divorce her. He should consult with an attorney.
Only if the non-custodial parent give up his parental rights.
No. If the fiance is the natural father, then he does have rights to his son. Getting married doesn't give him legal rights to your child (assuming he is not the father). He must adopt in order to have legal rights.
No. Fabrice Muamba does not have any children. He does have a fiance named Shauna.
It would be better if you were married, but there are other, less pleasant ways she can get custody. See related link.
Yes. You have no control over who accompanies him to such events. If he is abusive toward you then discuss the situation with your attorney and take the matter to court if necessary.
Maybe. If the fiance has a custody or divorce settlement with the child's other parents, it may include a morality clause that prevents him/her from living with anyone of the opposite sex outside of marriage while the child is in the home. Your fiance should check his/her divorce/custody settlement to determine whether such a clause exists. If not, he/she should still run the idea past the other parent prior to your moving in together. Even without the clause, the child's other parent may attempt to raise custody issues regarding the situation.
