This is a really weird question, but here goes.
My baby brother went to rehab for drugs awhile back. While he was gone, his girlfriend left him, and married some guy. She also got pregnant by this guy she married. Well my brother got out of treatment, when she was two months pregnant, and left her husband to get back with my brother. She had the baby yesterday, and my brother signed the birth certificate, even though the baby isn't his.
What I'm wondering is, can they get into trouble? I thought, since she was married, no-one could sign the birth certificate without a DNA test, however she failed to tell them she was married.
