I want to legally make my daughter and her best freinds "best freinds forever" as a Christmas present. Is this possible?

A Motion and Order to Declare A and B Best Friends Forever.

Any competent attorney can draft such a motion. It will consist of the standard of law to apply, the findings of facts as presented to the court, conclusions of law and a legal ruling. The unfortunate part is that no matter how well crafted, it will be denied because judges just don't have a sense of humor. You see, of the four things I mentioned, none of them actually exist at law. So, no, you cannot do what you want to do and make it stick in a legal sense.

But, as a Christmas gift, you could have your lawyer draft a sham pleading that looks real and will likely make everyone involved feel good. It can't be presented or enforced, but isn't it the thought that counts? Merry Christmas!
