Conservatorship
  
They told you not to toast waffles while taking a bath. But you said, "no, this will be great. I'll get to eat Eggos while relaxing in a nice, warm tub." But then the cat tried to walk across the porcelain edge and knocked the toaster into the water...
Now they're feeding you your waffles while making choo-choo noises, and the only TV shows you can follow were made for two-year-olds. Who's going to take care of your finances while your brain recovers from your unfortunate electrocution?
Here's where the concept of conservatorship comes in. A court will appoint someone to take care of your financial affairs while you're incapacitated. You become the conservatee. The person put in charge...an accountant or a lawyer or maybe a close, trustworthy friend or relative (certainly not the treacherous cat)...is the conservator.
In real life, this can come up as people get older and need someone to look after their finances (and maybe their person as well). Otherwise, it's a field day for every telemarketer who can get through.
