Legal Question in Wills and Trusts in California

Since this is your mother's trust, she needs to be the person who hires an attorney to amend her Trust, assuming she still has mental capacity and assuming she wants you involved with her affairs. The Trust may also have a provision for having the named successor trustee take over if she becomes incapacitated (usually requires a doctor's letter, sometimes two). Are you the named successor? I hope this helps.
