Capacity To Contract
By, Gwen Uselman
Intoxicated
If you are intoxicated you cannot fully commit to something because you obviously might not remember that whole deal in the morning.
Underage
If you are underage you aren't capable of having all the knowledge of knowing what you are agreeing to and making the correct choices and decisions.
Mental
If you are mental clearly you are incapable of making contracts with anything. You are not stable therefore you cannot make choices on your own or ever.
