You want money, but you do not want to settle? You are missing 90% of your facts, but my educated guess is that you are out of luck. If the Defendant advanced about 3% as there estimate of your Permanent Disability, then all your remaining value is subject to settlement. I am sorry that your Attorney died, but you should probably try to get another one.
We give free general concepts to be helpful, but you should give ALL your facts to a licensed Attorney in your state before you RELY upon any legal advice.
An Advance on Permanent Disability Indemnity due is possible... but extemely unlikely.
The Insurance Company holds the purse strings.
It is the Insurance Adjuster's personal judgment as to whether it helps the INSURANCE company to pay you some of the money still outstanding to you prior to a judge ordering it.
If the adjuster knows you're desparate, the answer is typically 'no, thanks.'
Did the attorney file the Serious & Willful Misconduct Petition? Do you have all your witnesses and documents ready to prove what was in the mind of the employer (proving a mindset being virtually impossible)?
Sounds like you need a CERTIFIED SPECIALIST workers comp attorney .... and soon.
If there is ANY possibility of you WORKING instead of begging an adjuster for money, I strongly suggest finding work appropriate for your level of functioning. Begging an adjuster for money always turns out badly for the injured worker... they presume you will take any low-ball offer instead of fighting at trial because you can't afford the trial it takes to get through a Workers Compensation trial.
DON'T SHOUT. You need to get another attorney ASAP if you want your case settled or tried.
