How can I compel trustee to co-operate with revocation of trust?

This is complicated. I am a surviving spouse of a revocable trust. I am trying to revoke my share and make my own trust. The only asset is my co-op apartment. My co-trustee who is an accountant is refusing to provide the documents need by the lawyer who is going to do the stock transfer. They are both afraid of my stepchildren who are remainder benificaries. I have every right to revoke my share!! My lawyer is trying but it is a bit of a mess. Can they be compelled by the court to co-operate with me?
