My contract says this ....
A deposit of one week is required to put this contract into effect. It will be applied to the last weeks payment, upon termination of this contract. I also agree to give a minimum of two weeks written notice, if I intend to withdraw my child from the childcare. if two weeks notice is given, I agree to make payments up until the last day of attendance and the deposit will not be refunded.
I think I am at a loss, I do not mention anything about holding a spot !
