Mega Millions Proposition
I Christopher Ferry, herby [sic] agree to equally share 100% of the earnings I win from the Mega Millions drawing on Tuesday, October 23rd, 2018 with all parties that like, share and comment on my Facebook post that states this propostiion [sic]. This is an official legal document that can be used in the court of law.
It's then signed, presumably by Christopher Ferry. The writing is in all capital letters, so I took the liberty of guessing at the intended capitalization rather than hurt your eyes.
After liking, sharing and commenting on the post (just kidding), I made the foolish mistake of reading the comments. There seem to be many people out there on the Internet who are confused about the basics of contract law.
To those confused souls, I now say, you're welcome.
A surprising number of very confident commenters on the post noted that the document was not legally binding because it was not notarized. This is nonsense. While notarization may be required for certain documents or agreements, parties can enter into contracts with each other without notarization. Take, for example, oral agreements, or the website terms of service for reading this blog post, which state that by reading this I now own a small, yet noticeable percentage of your soul and that you are required to enter into binding arbitration with me to prove otherwise. This story of a winning lawsuit to claim a portion of lottery winnings as a result of a verbal agreement is yet another example. People can, and do, enter into non-notarized contracts every day.
A smaller number of commenters speculated that the document may not be legally binding because it had numerous spelling errors. While spelling errors may occasionally be of legal significance (by misidentifying parties or terms, or injecting vagueness into the agreement), the errors here do not appear to have this effect. If spelling errors meant doom for legal documents, than a disturbingly massive percentage of contracts, pleadings, and judicial opinions would be rendered void.
Some other folks point out that the document is not legally binding because there is only one signature on it. A contract, they think, needs to be signed by all parties that are bound by it. This does not appear to be the case here, however, as Ferry's post is an offer that invites acceptance by performance. Ferry indicates that to accept his offer of sharing the earnings he receives, a party need only "like, share and comment on my Facebook post that states this propostiion [sic]." Once a party has done that, that person or entity will have fulfilled their end of the agreement.
On a related note, if Ferry ends up winning, a likely way he will whittle down the number of those who may have a claim against him will be to refuse to compensate anyone who did not completely perform their side of the agreement. Ferry notably requires that parties "like, share and comment" on the post, so anyone who only likes, or only comments would not have fulfilled their end of the bargain. His comments could make this issue a little more interesting, as he states that only those who "LIKE / SHARE / COMMENT" are eligible -- but these comments are parol evidence which some courts may deem inadmissible (particularly since the terms of the contract itself are fairly clear). And even if Ferry's comments are considered, they do not appear to contradict the terms of the agreement.
In short, the offer may give rise to a binding contract, provided that the party claiming to accept the offer has liked, shared, and commented on the post.
Unfortunately for Ferry, if he wins anything in the lottery, he will be required to share those winnings with anyone who fulfilled the requirements that he posted. Whether that is $1.6 billion or $2.00 -- Ferry agreed to share "100% of the earnings" that he would win, rather than limiting his performance only to a situation in which he won the jackpot. At the time of this writing, there are only about 30 minutes to go, but it will be interesting to see if Ferry wins a substantial amount, but less than the jackpot, as this may be enough for certain delightful people on the Internet to seek to recover their $1.32 to which they are entitled.
It's also fun that Ferry states that the document "can be used in the court of law."
Good luck to Mr. Ferry, and to all others out there who, like me, are excited for their inevitable life of leisure once the winning numbers are announced.
