Unless you're facing an emergency and need documents right this very moment, it's best to avoid the temptation of using generic, online fill-in-the-blank forms for your power of attorney, will, etc. The same goes for those generic, mass-market websites that offer cheap wills and trusts, but which often are nothing but a nightmare to sort out afterwards in Probate Court.
A licensed attorney will be able to create legally sound, effective estate planning documents for you that will accomplish what you want and minimize the headaches if you become unable to make your own decisions, manage your affairs, or pass away.
