Looking for someone to explain clearly, two particular exceptions to the parol evidence rule. The oral conditional precedent and also the collateral agreement. Thanks
I'm going to be very brief so someone else may want to elaborate.
1. "collateral agreement" is if there is separate (additional) consideration for a related agreement.
2. "oral condition" would be evidence of a condition that had to be met in order for the contract to be formed.
- proof is usually allowed despite parol evidence
these are the general principles
