Caveat to protect financial interests

5 yrs care for mother. Made a claim, emailed to the administrator, 3 months after probate was granted. Advised to refrain from distributing any assets until the claim and potential abuse are resolved. Discovered abuse of the EPA. Evidence. Bank statements affidavit. No correspondence, just promises to engage. Stalled communication, I believe. 3 days before probate finished, responded. Recognized my claim. Made an offer. I counteroffer. Again, EPA stalled, made out to make out to reoffer. Declined everything. After the probate finished. I would like to protect my legitimate interests. The property is all that's left. Protect the property from being sold until my day in court?
