My mother in law lives with my sister in law, they are in a house with no power and no got water. What can we do?

Call Adult Protective Services and report this as medical neglect of an elder.

If this is a medical emergency, call 911, i.e., if she's in terrible pain.

i saw a news article 20 yrs ago about a KY family who were living in an old school bus . both parents were in the tree service business but left the young kids in the care of responsible teen kids . theres a lot of stuff they didnt have but love and responsibility werent absent . a**hole neighbors called child services . child services found people doing the best with what they had -- very encouraging to me . i once lived in a 69 chevy van with my wife and son . before you knew it we were building the most beautiful home in all the midwest .
a poor man got poor ways ..

Hi Sophie, I'd like to point out a little something to you that you may not of thought of. I'll start by saying that when you call APS, you really don't want to tip your hand and let the guilty party know what you're doing. Think of it as something similar to a card game, because anytime you play a card game good players know not to tip their hands to reveal their cards. The same rule goes for calling APS, don't tip your hand and reveal your tricks to others. You really don't want the guilty party to know what's going on, especially since there is abuse going on in the situation. Anytime and abuser knows someone's coming, they'll make everything look and sound presentable. My abusive mom did this when they were expecting a social worker or someone from CPS to come in and check on the situation at home. Use this example as a good reason why it's never a good idea to tip your hand, you want the APS to walk in unexpectedly and find the situation. That way, the abuser has no chance whatsoever to hide any evidence of any wrongdoing, because APS will come unannounced when you least expect it.

Even in Georgia, no power can be dangerous to life. You can also call the county health department or the city code enforcement department to address the no power and no power issues.

Be prepared for anger from your SIL and MIL though, as a municipal inspection would require that they get power and water. If not, I suspect the house or camper would be condemned and deemed unfit for living.

Is there some reason there's no power or water? is it because of financial desperation?

Correction ...Second sentence should read "no power an no water issues".

happened to somebody I knew and they came and put her in a nursing home

hospice shouldn't cost anything, however

Wow, that is messed up. Your mother-in-law needs to be in hospice. Good luck!

Get on the phone, call Adult Protective Services. Call Sis and tell her APS is on the way. Click on this link to identify who to report elder abuse to in your state. http://www.ncea.aoa.gov/Stop_Abuse/Get_Help/State/index.aspx

Also, if the situation is getting critical or dangerous, call 911 and let the cops deal with it. It sounds just ridiculous.

Call Adult Protective Services in your area ASAP. If you know her doctor, call him about this situation. If you can't locate Adult Protection Services, then your local library maybe able to help you.
