What is an illusory promise?
A statement that appears to be a promise but leaves performance completely up to the promisor.
Why is an illusory promise not valid consideration?
Because there is no real commitment — performance is discretionary.
What is past consideration?
A promise made after something has already been done
Why is past consideration not valid consideration?
Because there is no bargained-for exchange at the time of the promise

No. It is past consideration — no bargained-for exchange
What is a pre-existing contractual duty?
Promising to do something you are already legally obligated to do.
Example: A paramedic saves someone and later the patient promises $2,000. Is this enforceable? Why or why not?
No. It is past consideration — no bargained-for exchange
Why is a pre-existing duty not valid consideration?
Because you are not giving up anything new of legal value.
