The Legal Rights of Imaginary Friends

[Matchsticks]

Last night, while suffering from a bout of isomnia, the weirdest thing popped into my head. What are the legal rights of an Imaginary Friend? Thinking back to a few episodes I can assume that:

1. Imaginary Friends are allowed to get married. (My So Called Wife)
2. Imaginary Friends are allowed to have jobs and get paid fair wages.
3. Imaginary Friends have to follow the law and they will be punished like a human for breaking it. (My So Called Wife, WTIAWTIAW)
4. Imaginary Friends can get Driver's Liscenes. ('Bus the Two of Us')

Now that brings up some questions for me. If IFs are allowed to get married do they need permission from their owners or is there an IF age of maturity where they can get married w/o permission of their owners? If there is an age of maturity why would a place like Foster's be needed for some of the older IFs (such as Wilt, Ed, Duchess, Coco, and Uncle Pockets) unless the IF age of maturity was much older than that of a human. Or are IF considered to have the legal rights of a Minor therefore they will always need a home to stay in because they are not legal to move out on their own?

So, any thoughts?
