Find a really good CPA — pay them what they’re worth - probably upwards of over $500 an hour... worth every penny. Try to find one that specializes in issues dealing with the elderly - there might be other things you need to know... might as well use up the whole hour.
Also lawyers who deal with the elderly charge less and often have great advice. My very limited experience is that the very best are often cheaper in the long run. They’re not doing on the job training and they know their stuff so well you won’t be charged for ‘research’... You’re in my prayers.
Thank you.
