Explanation:
When an agreement consists of two parts, one legal and the other illegal, and the legal part is separable from the illegal part, the legal part is considered valid.

Legal and Illegal Parts:
In many agreements, there may be two parts. One part may be legal, and the other part may be illegal. For example, a contract may include a clause that is legal, but may also include a clause that is against the law. In such cases, it is important to determine whether the legal part of the agreement is separable from the illegal part.

Separability of Legal and Illegal Parts:
If the legal part of the agreement is separable from the illegal part, then the legal part of the agreement will be considered valid. This means that the parties to the agreement will still be bound by the legal part of the agreement. However, the illegal part of the agreement will be considered void.

Example:
For example, if two parties enter into an agreement to sell a car, but the agreement also includes a clause that requires the buyer to pay an additional amount of money under the table, the clause requiring the buyer to pay the additional money would be considered illegal. However, if the sale of the car is legal, then the legal part of the agreement (the sale of the car) is separable from the illegal part of the agreement (the requirement to pay additional money under the table).

Conclusion:
In conclusion, when an agreement consists of two parts, one legal and the other illegal, and the legal part is separable from the illegal part, the legal part is considered valid. This means that the parties to the agreement will still be bound by the legal part of the agreement.
