Dowry hunter - Aunt's partner tries to cheat the grandmother

Well, the other party approached us with the insinuation that Grandma was no longer quite clear-headed. We couldn't understand that.

I can tell you from my own experience that as an outsider you only notice this late. With my grandma and her second husband, my grandma had been saying for a long time that he was showing early signs of Alzheimer's. We didn't want to admit it (even though we were regularly on site), especially since he still drove short distances by car. My grandma contributed to this by always saying our names when greeting us; otherwise, we would have noticed much earlier that he probably hadn't been able to associate our names for a long time.
The two complemented each other quite well. She managed everyday life and took over the thinking, and despite his age, he was still fit enough to carry the groceries.
He was not malicious but did everything his wife ordered (as long as he could remember). However, the mental decline then proceeded increasingly faster.

So if you only come by every few months, I wouldn't rule out that she can hide it well from you.
How is it, you ring the doorbell. You greet with "Hello Grandma/Grandpa," give a hug. The other person puts on a smile and suddenly you haven't noticed anything. During the conversation, things from the past come up (they can usually still remember these), and when you get to a point where the memory no longer works, the whole thing is just laughed off with a little joke about it.

I stay at home, they just want to save the house from the uncle. Grandma is secondary.

...then you can just throw the power of attorney in the bin. Who is supposed to check if grandma is no longer clear in her mind? And what does that mean? How is that supposed to be defined?

No one can just throw it in the bin with a notary. Grandma herself defines the point of validity - also separately for all aspects (health, assets, ...).

I'm staying home

I know where your house lives...

I know where your house lives...

Home fits Grandma's house

No one can just throw that in the trash with a notary. Omi defines the point of effectiveness herself – also for all aspects (health, assets, ...) individually.

No notary who even remotely understands their business will draft you a power of attorney containing a clause like, it only applies if the principal is no longer capable, etc.... it's simply not practical. You would first have to prove that this clause has come into effect. And no one wants to get involved in this legal game. I am not a lawyer, but professionally I deal a lot with these topics. When I am presented with a general power of attorney, the first thing I do is check if such a "restriction" is included... if yes, I do not accept it...

But I believe I have so far seen at most one such notarized power of attorney that I have rejected. Because every notary knows that makes no sense.

The scope is of course defined individually by the principal... but a restriction based on health status or similar makes the power of attorney practically unusable...
