Personally i would keep the child's last name or hyphenate it
Yes, a father can change his child's last name. However, this depends on the custody arrangement, and who has primary custody.
If he is married to the child's mother the decision is theirs to make, but if he is not married to her the mother decides the child's last name.
No. The mother is the one deciding what last name the child will have. And I assume you and the child are not the only ones having that last name. You don't own it.
In the US, yes.
You will need to go to your local SSI office in order to change your child last name legally, you will also need to call all information that are in your child name.
When a child is born out of wed lock.is the child last would be the mothers or the fathers last name? fathers name
yes, through the courts
If the child has your genes, it is yours, regardless of its name.
In the US, parents who sign the birth certificate can name the child anything they like.
Child support has nothing to do with the child's name. Just because you pay support, the mother is not obligated to give the child your last name. Many people feel that the child will be more comfortable having the same last name as the custodial parent.
Typically, a child born out of wedlock takes its mother's last name. However, in the US, one may pick any name for one's child.
