Is there a minimum amount of money that makes it worth consulting an elder care attorney to try and save my inheritance?

You should see an estate planner. However, be prepared that the government generally expects us to pay our own way until assets run low enough for Medicaid qualification.
Still, there may be ways to protect some assets. As Jeannegibbs said, it's time for legal advice.

If your father has good income and assets, it will be worthwhile to visit an elder care attorney and/or an estate planner.

llevy.......does your state have any Senior Financial Advisors? I'm going through just about the same thing you are, I contacted an Advisor last week, and we've gotten the "ball rolling" on saving my inheritance. My mom is like your dad, not rich but managed to save up a little, and she has a very good income, my dad was retired military. Alot of these places do work pro-bono, or at a very good rate please look into it.

I recommend you pay an Elder Law attorney for a consultation. The consultation charge usually runs between $100-$200 for about 30 minutes and in some cases longer especially if the attorney is a sole practioner or like my husband where he doesnt "bill hours" and have to account for his time. You can gain valuable knowledge which may save you thousands in the longer run. With estate planning and elder care, timing is everything. Good luck.
