Your summary is labeled "probate fraud" and that is a serious charge. That suggests that there is more here than simply not understanding the terminology of the paperwork.
You should meet with an attorney to discuss this, right away. You can either find an attorney who gives initial consultations at no charge, or someone who will wait to collect until you receive your share of the estate. But without an attorney to review your paperwork, you are groping in the dark, here.
You certainly do not want to accuse ANYONE of fraud without having compelling evidence, because you open yourself up to a defamation claim. The attorney can help you to understand what has transpired and how you should proceed, if at all.
