You have got quite a case on your hands their. This is way too much of a fact-specific situation to get into on this forum. You need to immediately hire an attorney to represent your interests and contact all parties involved. Depending on the facts of the case you will have to go through the process of discovery to find out the facts you are looking for.
With respect to your question about do lawyers keep records of the trusts/wills they wrote? Yes of course. Most lawyers keep records of almost everything they've ever done.
This is not legal advice nor intended to create an attorney-client relationship.
Yes, attorneys keep records of the estate plans they create. However, ethics prohibit them from discussing those plans with anyone other than the client or persons who have permission from the client to speak with the attorney. Will contests (litigation) are always uncertain and usually expensive, but will probably be necessary to unravel this mess. In Colorado, where I practice, a trustee must provide an accounting to the trust beneficiaries if requested to do so. Your attorney should be able to get an accounting for you if you are in fact a beneficiary.I do want to point out that you and your family may have misunderstood what the attorney meant when she referred to the trust as "irrevocable." Your father's trust may be have been revocable when he executed it, but upon his death, it became "irrevocable." Good luck.
