True, a will is the most common estate planning tool, but it is not a good tool for you to use. Almost everybody owns their home and bank accounts in joint tenancy. Yet joint tenancy often causes families horrible legal nightmares. You have many options better than owning property in joint tenancy, and they come with substantially less risk. By setting up a living trust, you avoid the need for conservatorships and guardianships.
Most people assume their estates are worth far less than they actually are.
Most estates do not qualify. No two personal situations are the same. That's why no two living trusts should be written the same way. The only estate plan you can depend on is one that is custom prepared by a qualified attorney. Most attorneys know very little about estate planning.
