My POA states I can take fair and reasonable compensation for my ongoing care of my mother. My attorney wants me to discuss this with my sibling. Any advice?

I suspect the attorney is thinking ahead. He/she doesn't want to get blamed if a caregiver contract is drafted and your sibling objects.

However, I don't see that it your's siblings business at all if he/she isn't providing help. Or unless your sibling is co- or successor proxy.

But if he/she does decide to help, he/she might be entitled to compensation as well. That might also be a concern of the attorney.

However, I agree with RainMom and Igloo. I have a feeling there are tense or harsh relations between the two of you and your being paid would be a potentially explosive issue, and the attorney doesn't want to get caught inbetween. And that's a legitimate concern.

Like Rainmom, I too ask..... what’s the backstory on all this?
More details will be helpful.

What reason does the attorney give for wanting to discuss this with your siblings ? Out of curiosity, how many siblings? Do they live locally?
