My brother's girlfriend is a minor and pregnant. She is 16 and 8 months. She has been living in a dormitory at Job Corps for the last six months I believe and is now on maternity leave. She and my brother have been staying at my house because she does not get along with her parents. The parents are on drugs and her mother goes back and forth on approving of the relationship with my brother. Currently she hates him. Recently she threatened my brother's girlfriend saying that because she (brother's gf) is a minor, she (gf's mom) has legal rights to the baby and every decision my brother's gf makes has to be done through her. Her mother told her there is no way she is giving the baby my brother's last name and he will not be allowed to see the baby. The mother also said that if my brother's gf does not follow through with her decisions for the baby she will take it from her and put my brother in jail. My brother just turned 20 yesterday. Her mother knew they were sleeping together (she took her to get an abortion a month previous to this pregnancy), she even allowed them to stay at her house together. Now that she is fighting with my brother's gf, she wants to press charges and control her daughter through the baby. My question is, is this legal? we live in california.
