Legal Question in Wills and Trusts in California

It's probably a revocable trust, and it probably can't be amended by anyone but your mother. But no one can answer your question without reviewing the document.

I agree. You also seemed confused about the trust. A trust is run by a trustee. I'm not sure what a consecutive is. Your power of attorney may include some authority, but it seldom allows such an amendment. Seek counsel who is familiar with estate planning matters. In some instances a court can implement changes, but it is unlikely you can do so. She may not be able to change it either if she does not have testamentary capacity (or contractual in a trust).
