Mother recently widowed and not able to manage financial matters without oversight. I've been helping her alot, but the estate plan is complicated. So, trying to get changes made to add corporate fiduciary to manage affairs with mother as co-trustee. The corporate fiduciary would then become successor sole trustee and executor. There are many beneficiairies that don't get along, so they would be a neutral 3rd party. Have already hired corporate fiduciary and in process of updating estate documents to make these changes. Mother was happy with this new arrangement, but now one sibling with successor trustee and financial POA is emotionally manipulating my mother with lies to try to stop her from making these changes. Motive is to retain control over of finances and trust assets.

There are a lot of really good attorneys on this site, I will do limited appearances which are preparation of court documents it is , less expensive. However generally I believe an attorney is better than none.
Estate Planning Attorney
If mother retains capacity, she could revoke her current financial POA, and sign a new POA appointing a trusted agent. Also, mother could set up an irrevocable trust outlining her estate plan, to protect her and her plan against the financial abuse. All of this would need to be discussed with and set up by an attorney.
