I have a detailed list of how to reach all my bank accounts, email accounts, URLs, etc. My will states that everything I have will be divided evenly between my brother and father so I would assume they would get permission to cash my business (and personal) checks and just let the domains expire when they will. I know neither wants to "run" the business.
My life insurance is payable to my father and is enough to cover the balance of my mortgage (term insurance, not mortgage insurance). My understanding is that the family will keep my house as a vacation home not sell it. My other properties and businesses will probably be sold.
This is all assuming I go before all of them
Hopefully I will be completely out of adult by the time I die 30 years from now and all I'll have to worry about is what to leave to the nieces!
