LAREDO, Texas — A court has ordered state Sen. Judith Zaffirini to stop paying herself out of funds that she is supposed to be managing in trust for the heir of two wealthy sisters.

Zaffirini and her associates have paid themselves more than $1.2 million in various attorney’s fees and executor fees out of a cluster of interlocking partnerships, trusts, and an estate they control for the ostensible benefit of Rocio G. Guerra.

Guerra sued Zaffirini and her associates, alleging that they are effectively looting the inheritance that her mother and aunt left her and her two children. That inheritance, mostly real estate in a fast-developing part of Laredo, has been valued as high as $150 million.
