Office lottery pool agreement template

A lottery pool agreement fits on one page and answers six questions: what is being played, who is in with how many shares, when and to whom payment is due, who keeps the ticket, how a prize is divided and what happens to someone who did not pay. Fill in the fields below and the text writes itself, ready to copy, send or print.

What each clause settles

The first clause pins down the game, the drawing and the cost: for instance five 6-number Mega-Sena tickets at BRL 6.00 each, BRL 30.00 in total. The shares clause lists every member with the amount owed, already computed in cents. The payment clause sets a deadline and a recipient. Without those three, the argument after the drawing usually opens with "I thought it was ten bucks".
The keeper and late-payment clauses are the ones groups forget most. The ticket stays with one person, who photographs it and sends it to everyone. Anyone who does not pay by the deadline is either out and gives up the shares, or the organizer covers the amount and keeps them; the agreement picks one of the two. Finally, a prize is divided by share, stray cents go to the largest remainder and whoever collects it pays out within an agreed number of days, three by default.
The SHA-256 fingerprint seals the document. It turns the text into a 64-character string: the empty text gives e3b0c442 and the text abc gives ba7816bf, which are the standard reference values. Changing one comma in the agreement changes the whole string. Whoever receives the agreement pastes the text into the checking field and sees whether it matches the string provided. That proves the text was not edited, but it does not replace a signature or legal advice.

How do I work out the price of each share in a lottery pool?

Divide the total cost by the number of shares. Five Powerball tickets at $2 cost $10; split in 4 equal shares, each is $2.50. When the division does not come out even, such as $10 in 3 shares ($3.3333...), the calculator works in cents: 1,000 cents divided by 3 is 333 each with 1 left over, so one person pays $3.34 and two pay $3.33, adding up to exactly $10.00.

Frequently asked questions

What should a lottery pool agreement include?

The game and drawing, the number of tickets and numbers, the total cost, a list of members with shares and amounts, the payment deadline and recipient, who keeps the ticket, what happens to non-payers, the prize split and the payout deadline. The template on this page has every one of those.

Is the agreement legally binding?

The agreement is a private arrangement between the members and says so in its own text. It records what was agreed and helps settle disagreements, but it is not a lottery document. For large amounts, get legal advice.

How can I prove the agreement was not edited?

With the SHA-256 fingerprint. The organizer sends the 64-character string with the text. Any member pastes the text into Check a contract I received: if a single letter changed, the result is a mismatch.

Can I print the agreement for signatures?

Yes. The Print button builds the sheet with one signature line per member. In the print dialog, turn off Headers and footers so the site address does not print on the paper.
