Nursing home tried to move my grandfather without telling us

Location: Maine, US

Essentially what the title says. This is my mom's dad, and she is his POA, and general advocate for people in our family. I'm posting this on behalf of her as she's not tech savvy, and I hope I can at least get a few answers here. ("We" refers to my family; or my mom and I).

My grandfather has Alzheimer's, and has had it for a while. He is fairly independent (he's mobile, albeit very slow and can't do it for very long; he can shower, eat, and do most tasks by himself), but he sundowns terribly and is often confused. An example: he could go out to lunch with my mom relatively normally, but he falls asleep about 10-15 times in an hour span (no matter if he's eating or not), confuses my mom for my grandmother (who is deceased), has no idea where he is or what he ordered. He can say he had a great time, and 20 minutes later if you asked him what he did today, he'll answer with "Nothing" or "I worked at the mill". He doesn't recognize me anymore, and can't remember my name (some days that I even exist lol). Just to give some context on his current state.

We tried having him live with us, but it was a nightmare. He didn't get upset or violent, but the love we all have for him clearly wasn't anywhere near the level of care that he needed (from a professional team of medical staff with the licenses to help him).

He's been in a nursing home for about a year, but it was supremely expensive and we've just been waiting for a spot somewhere else to open up.

That happened about 2 weeks ago. He got moved in to the new place, and there were immediate issues-- he attempted to escape twice, made it out once (not very far, a nurse clocking in caught him), and was generally more confused due to the move. Even on his worst days, he's never violent or volatile to others or himself. He wasn't any of these times, either. They immediately threatened to kick him out, even so. My mom sat down with the director and de-escalated things, clearly stating that his paperwork has him listed as a flight risk (or whatever the correct terminology is, I'm unfamiliar) and the worst thing he'd done there was make it to the parking lot.

We never got any paperwork on anything-- rules, regulations, not even a menu or map to look at or fill out.

My mom drove to see him today, and he's been settling in a lot better. The staff that work with him tell us he's a sweet guy, and even offers to help with laundry (he likes doing chores haha), so we've all been feeling pretty relieved.

Well, he was getting a haircut today, and the hairdresser (who is one of the nurses as well, she just cuts hair once a month) told my mom she was "sad to see him go".

My mom asked for clarification, and the hairdresser told her along the lines of "He's being moved to [different facility], right?" My mom said no. She went up to ask other staff members what was going on, and they said he was being moved to a different facility... without telling any of us.

Obviously they didn't say the last part. But there was no paperwork. There were no emails. No communication. Literally nothing to tell us that he was being moved.

I know things can get legally iffy when it comes to situations where a resident goes to the hospital and then is refused to go back, but he's been there this entire time. No other family members were told (they haven't even seen him in the new location yet). He hadn't been kicked out. He hadn't done anything besides the first incident(s) with escaping.

If the hairdresser hadn't said anything, they were going to move him by themselves, without telling us.

Thankfully the new facility takes his insurance, and the director immediately got in touch to help us move him on such short notice (they were going to move him literally Tomorrow). It's an actual locked facility, at least. Unfortunately it'll move the distance from an hour-ish away to nearly 3 hours drive time (6 if you count both ways).

We're all just utterly baffled and confused. We triple checked our mail (physical and digitally), checked with other family, checked for any kind of sign that we missed something, but there is absolutely Nothing. They were just going to move him without telling us (and presumably without consent/permission from anyone at all???). My mom asked just in case whether or not they'd asked my grandfather or not, and they hadn't (not that he can consent as he literally does not understand what is happening most of the time, or forgets almost instantaneously),

Q:

Is there anything to be done here? Negligence, or something similar? Suing or something else?? And I apologize for the vague language, I'm unaware of the specifics of legal jargon.

I know how rough the medical field is right now, but surely this isn't allowed, right? None of us are sure what to do here. We're all a little too busy scrambling to move him this Friday. Hopefully the new place will be better for him.

I hope I gave enough info on things. If there's any questions, I'll try and answer them as best I can (or call my mom to ask lol). She's not one for hyperbole and these past few weeks have been filled with a lot of crying and stress.

And please be honest if the case happens to be that there *is* something to be done, but it's just probably not worth it. We have *some* savings, but if it's going to be a steep uphill battle, we probably could not afford it.

Thank you in advance.
