Is it possible for the parties in a binding contract, which may be cancelled, to include a condition allowing one of them or both to have the option to enjoy certain benefits?
Yes, in binding contracts that are liable to be cancelled, it is permissible for the contracting parties or either of them to make it a condition in the contract or later on, that they should have the option of conditionality in their own or another person's favor. The duration of this condition can be agreed upon by the parties, but if they cannot reach an agreement, the judge can specify the period based on customary practices.
