For a month-to-month tenancy to be legally valid, which must the contract include?

Oral or written consent alone is insufficient to establish a legally valid contract. Consent is just one element; without offer/acceptance and consideration, no binding contractual relationship exists, even if both parties agree to the arrangement.

Offer and acceptance establishes mutual agreement but is insufficient alone. Without consideration and proper consent, the contract lacks the necessary elements to be legally binding in a month-to-month tenancy situation.

Consideration (typically payment of rent) is essential but not sufficient by itself. A valid contract also requires proper offer/acceptance and consent to create an enforceable month-to-month tenancy agreement.
