Is a partnership in real estate or land binding if there is no desire to partner with the other party, given that no new changes have occurred in the property's features?

What was asked about has two scenarios:

The first: If there is an actual partnership contract, then rescission is permissible by mutual consent. The second: If it is merely a promise to partner in the future, then it is permissible to withdraw from it, because fulfilling a promise is not obligatory according to the majority of scholars, unless the one who was promised entered into an obligation because of it, according to the Malikis.
