No current need-to-know Spouse's sib + parent would deny, but strongly suspect sib has POA for parent. To satisfy curiosity, wondering if there is a way to determine if spouse's sibling has Power of Attorney for their elderly parent. Suspicious because infrequently when my spouse or one of our adult children offers to help w/ financials in any manner, spouse's parent says, "No, no, no, so-and- so (the sibling) will handle that." Thanks in advance.
To ask either the parent or sibling directly is a waste of time, because they each have a strong history of lying. Sad, but true.
