How do I get my inheritance from a trust?

Assuming that you have already asked for a copy of the trust and information about it, and been denied appropriate information, then you need to hire an attorney who works on fiduciary litigation. The attorney will likely need to send a demand letter to the Trustee of the trust. If that does not result in appropriate action by the Trustee, then your attorney may need to sue the Trustee for an accounting and for a copy of the trust.
