What happens if he didnt sign the birth certificate but is married to her?
The husband is presumed to be the father of any children conceived/born during the marriage, unless/until proven otherwise.
Can the father that didnt sign the birth certificate in the child don't have his last name force the mom to take a DNA?
Can you put the father of the child in jail if he didnt sign a birth certificate or take a DNA test?
Paternity must be established before an order for support is entered. This is done by: genetic testing; presumption, where the parties were married when the child was born/conceived; acknowledgment of paternity either in writing or in open court; default, where the alleged father fails to cooperate in the process.
