The answer given does not imply that an attorney-client relationship has been established and your best course of action is to have legal representation in this matter.
Not likely. You should take the time to meet with and consult with a Spokane probate attorney. Most probate attorneys provide for a free consultation. Go to the "find a lawyer" tab and look for a probate attorney to talk with. I am sorry for your loss.
"Estate" of your brother means any checking and savings account balances, any real estate and personal property, anything of value. That is the estate. Someone will need to probate the estate, however. Nevertheless, no one in his family is liable. However, if he has a spouse, she may be liable for his debts, assuming they were incurred during the marriage. Condolescences.
