My question involves estate proceedings in the state of: New York

John Doe is a divorced man and grantor of the John Doe Revocable Living Trust. The trust names two beneficiaries: His daughter Tina, and his ex-wife Jane Doe, each shown as beneficiaries to half of John's assets. When John dies, his daughter, who resides nearby, finds the Revocable Living Trust.
After reading through it and realizing that she only gets half of her father's assets, she decides to destroy the trust document and she tells her mother Jane that no will or trust could be found. She then gets all of John's assets, while Jane gets nothing.
What can John do to prevent this outcome?
