Cal. Civ. Code § 441.150
The attornment of a tenant to a stranger shall be void, and shall not in any wise affect the possession of his landlord, unless it is made:

(1) With the consent of the landlord; or

(2) Pursuant to or in consequence of a judgment at law, or a decree in equity, or sale under execution or deed of trust; or

(3) To a mortgagee, after the mortgage has been forfeited.

Plain English

Missouri law under Mo. Rev. Stat. § 441.150 addresses a legal act called 'attornment,' which is when a tenant formally acknowledges a new person as their landlord. Under this provision, a tenant's unilateral decision to attorn — that is, to recognize someone other than their current landlord as the new landlord — is generally void and has no legal effect on the existing landlord's rights or possession of the property. However, the rule carves out three exceptions: when the existing landlord consents, when a court judgment, decree, or foreclosure-related sale compels the change, or when the property's mortgage has been forfeited and the tenant attorns to the mortgagee.

For Property Managers

Under Mo. Rev. Stat. § 441.150, a landlord's possessory rights are generally protected against a tenant's unauthorized attempt to recognize a third party as the new landlord. Compliant property owners and managers typically document any consent they give to a tenant's change of landlord recognition, ensuring that any such transition is clearly authorized. When a transfer of landlord status arises from a court order, execution sale, or deed of trust proceeding, operators generally coordinate with legal counsel to ensure the transition is properly documented and falls within one of the recognized exceptions.

General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.

For Tenants

Mo. Rev. Stat. § 441.150 means that a tenant generally cannot unilaterally decide to treat a stranger or third party as their new landlord — doing so is legally void unless one of the statute's exceptions applies. Tenants should be aware that if someone claims to be their new landlord outside of a court-ordered process, a foreclosure, or with the original landlord's consent, that claim may have no legal standing under Missouri law. Tenants who receive conflicting demands about rent payment or landlord identity may wish to consult a tenant-rights organization or legal aid service to understand how this provision applies to their circumstances.
