unwed mother putting man's name on bc

[THANKS_4THEHELP]

What is the name of your state (only U.S. law)? Indiana

When an unwed mother gives birth is the child automatically given her last name, if her boyfriend does not sign the birth certificate?

Can an unwed mother put a man's name on the birth certificate as the father if he has not agreed and is not there to sign the birth certificate ?

Will he be required to pay child support?
