Cal. Civ. Code § 5
Action to recover rent; evidence
Operative Text
Section 5. Such rent may be recovered in contract, and the deed of demise or other written instrument, if any, showing the provisions of the lease, may be used in evidence by either party to prove the amount of rent due from the defendant.
Under Mass. Gen. Laws c. 186 § 5, rent owed by a tenant may be pursued through a contract-based legal action. Any written lease or deed of demise that documents the rental terms is admissible as evidence by either side in such a proceeding to establish how much rent is actually owed. The provision makes clear that the written agreement, if one exists, serves as a key evidentiary tool for determining the amount in dispute.
Plain English — not legal advice.
Under Mass. Gen. Laws c. 186 § 5, a landlord seeking to recover unpaid rent generally brings a contract claim and may introduce the written lease or deed of demise as evidence of the agreed-upon rent amount. Operators who maintain clear, well-documented written leases are better positioned to establish the terms of the tenancy in any collection proceeding. Keeping organized records of the lease and any amendments helps ensure the written instrument accurately reflects the rental obligations at issue.

Mass. Gen. Laws c. 186 § 5 also gives tenants the right to use the written lease or deed of demise as evidence in a rent-recovery proceeding, not just the landlord. This means a tenant can point to the same written instrument to contest the amount a landlord claims is owed if the lease terms support a different figure. Tenants who believe a claimed rent amount is inconsistent with their written agreement may find it useful to consult a tenant-rights organization or legal aid provider familiar with this provision.
