Q

Vagueness of a contract

A

Performance must be either determined or ascertainable, otherwise, if neither, the contract is invalid due to vagueness.

17
Q

Determined performance

A

This is when parties expressly mention the performance. Eg they buy Thomas the horse.

A facultative obligation

This also determined performance. This is where the debtor is allowed to perform a different performance if he chooses. The creditor cannot choose performance.

18
Q

Ascertainable performance

A

This is where the contracting parties decide on a criterion/formula/specified person to determine the performance from two or more alternatives.

The alternative obligation as we are party chooses the performance from two or more alternatives.

Eg one or two horses from a set of three.

Impossibility of performance will not relieve the debtor from his obligation.

The generic obligation is where the performance is the term and by counting, weighing or measuring the object.

Once the object is separated from larger quantity, performance is the determined.
