Kathy Green, Transactions

For the past 17 years, Kathy has built a business supporting real estate brokers and agents as a transaction coordinator: reviewing and confirming documentation to be in compliance with State, local, broker and contractual requirements.  This involves constant updating with State, local and contract regulations as they relate to real estate transactions, as well as the changing requirements for disclosures and contractual obligations. Kathy helps to keep the parties’ compliance with the terms and deadlines of the agreements, communicating with the title and escrow officers, real estate agents and staff.  Kathy prepares a final digital file for brokers to fulfill their documentation requirements.

From 1992 to 2004, Kathy worked as a paralegal, specializing in complex civil litigation with an emphasis on real estate, trusts and intellectual property. This involved all stages of preparing Federal and State cases for trial: from evidence gathering and fact synthesis, to data management, legal research and writing, procedural timeline and calendaring, witness preparation, jury instructions and trial presentations with all types of media; and then finalizing cases on completion.

Kathy and her family live in Larkspur, California, and spend time in North Lake Tahoe.  Kathy is on the board of a charitable foundation, The Commons Foundation, whose goal is to fund, build and sustain a modern library and community gathering place in Larkspur.  Kathy’s interests are travel cooking, outdoor sports and music.
