Standard Agreement When Staking Someone in Poker (HELP PLEASE!)

[Chomper4]

I'm sure this isn't the right forum for this, but this is where I hangout and I know and respect alot of you guys opinions so I'll ask here. I'm not sure how to word it so bear with me. I actually have 2 separate questions so can you guys number your responses?

1) If someone "stakes" you money to play poker, what is the standard profit split if the deal is that the stakee doesn't have to pay the staker back if he loses?

2) If someone "lends" you money to play poker with the agreement that if you win, you will give the lender a certain percentage of winnings, but if you lose, you will pay the lender back in full, then what is the standard percentage the lendee gives the lender?

I hope these questions sort of make sense. Just give your opinion if you have one or if you have done deals like this, then share the details with me please? Thanks for the help guys.
