Guardianship

Is Power of Attorney enough to show I have guardianship of a child?
The mother of a four month old is in the County Jail for at least two years. The father is on probation, recently got into trouble and bonded out, they will probably revoke probation orders in very near future. Father has had custody of child since born on 9/4/08. The father wants to give Power of Attorney custody to his mother. All rights and responsibility of minor child to paternal grandmother. He plans to file papers in courts in Texas. If mother gets out of jail, can she come and get child? If so, how can I word the information to keep her from getting child. Her mother was in jail 2 months before she was born. Warrants went out while she was in labor, she then the tried to run with baby and go into hiding. I need to make sure power of attorney is okay for this circumstance.

How can I get a POA for an unconscious relative?
By sister is in the hospital with a massive bleed in her brain. The doctors say it could be monts before they know if she can function for herself. At this point she is in and out of consiousness and has no idea who she is. My brother in Oregon and I in California are her only surviving relatives. I have tried to talk to her bank, credit Card companies and mortgage company and no one will talk to me without her approval which she is incapable of giving. I don't want her to lose what little she has. What do I need to do?
Is there a way my older brother can gain custody since my parents are physically abusive?
When I was 6 years old my parents got arrested for a felony and my grandparents got full custody of me. After they were released, my brother and I were sent back to live with them After about three years they got custody back. Now at the age of sixteen they both have become extremely abusive an alcoholics. About two weeks ago we had gotten into a fight and my dad ended up punching me in the face, so I went to stay at a friend's house for about two weeks. Seeing how much happier I was my brother insisted on gaining custody but everyone kept telling us to go back and work it out so we did. Everything was alright, they were still drinking but they weren't picking fights and what not. After only a week and a half back my mom had an 'episode' and ended up punching my 22 year old brother in the chest and me several times in the back. She told us to get out and as we were leaving she said she was going to report me as a runaway. My brother went back in and said that this wasn't healthy for me and that he was going to get custody of me. Seeing as she didn't refuse we left. The only problem is I'm not currently in school, but am planning on either taking G.E.D classes or going to military school. Is their any way seeing the situation that I could still get emancipated or my brother gain custody? Or would they just put me in foster care?
