Where these elements are absent, vague, or unclear, the agreement may be void (as a result, no interest would be created). However, if the tenant is in possession and has paid money (i.e. rent) then there is a tenancy agreement. If a tenancy has been created (i.e. the tenant has possession and is paying rent), any vague terms of the tenancy agreement can be framed in the tenant’ s tenant’s favour using the principle of ''contra proferentem '' (i.e. the agreement will be strictly construed against the party seeking to rely on the contract), and perhaps even principles of statutory interpretation. The law seeks to recognize and validate the relationship where possible, even where the requirement to have a written tenancy agreement has not been met.  === 4.Agreements for Lease (Also Known as Agreements to Lease, or Agreements for Tenancy) === “Agreements for tenancy” are executory contracts in which the lessor promises that he or she and the lessee will enter into a written tenancy agreement at a later date. For an executory contract to have effect, generally the agreement must be in writing and must contain the essential elements of a lease. While the law states that the agreement must be in writing, this requirement is not always enforced. Consequently oral agreements may be considered valid. Also, the payment of money may point to the fact that a contract has been entered into. It should be noted that since this is simply an agreement to agree, the RTA does not yet apply. At this point, any money paid is a processing fee, holding deposit, or administration fee. Section 15 of the RTA prohibits fees to consider or process an application for tenancy.  If the money paid is part payment of rent or the security deposit (as distinct from a processing fee, holding deposit or administration fee), it is important to clearly identify that on the receipt at the time of payment (see definition of a security deposit). Until the tenant comes into possession, he or she has only a contractual interest, which applies only to “tenancy agreements”. Thus, failure to give the tenant possession is a breach of contract and not a violation of a property interest or breach of a tenancy covenant. When the tenant acquires possession, the agreement for lease is treated as a lease agreement, and the court may order the lessor to execute a lease (specific performance): see ''Horse and Carriage Inn Ltd. v. Baron'', [1975] 53 DLR (3d) 426 (BCSC). Recording the initial exchange of money as “rent”or as “security deposit” is important to create a basic tenancy agreement in situations where
