What Happens to an Eviction Case When the 3-Day Notice Has a Defect

When a landlord files an unlawful detainer based on a 3-day notice to pay rent or quit, the case lives or dies on whether that notice is legally valid. A defective notice is not a technicality. It is a complete defense that ends the case before it reaches any factual issues about rent owed.

What Happens When You Raise the Defect

If you file a Form UD-105 answer within five business days of being served the UD summons and raise a notice defect as an affirmative defense, the landlord must prove the notice was valid at the hearing. If the court agrees the notice is defective, the unlawful detainer is dismissed. The landlord must serve a new, corrected notice and start the process over.

The Most Common Defects Courts Dismiss On

California courts regularly dismiss unlawful detainers for the following notice defects: including late fees or other charges in the rent demand amount, failing to include a name, address, and telephone number where rent can be paid, improper service — particularly skipping personal service before substituted service, miscounting the three-day period by not accounting for weekends and court holidays, and serving the notice before the rent was technically past due under the lease terms.

How to Calculate the Three Days Correctly

The three-day period begins the day after service. It does not count Saturdays, Sundays, or judicial holidays. If day three falls on a weekend or holiday, the notice period extends to the next court day. A notice that demands payment by Sunday when the three days would expire Saturday is one day short and defective.

What to Do If Your Notice Has a Defect

Send a written letter to the landlord before the UD is filed identifying the specific defect and demanding that they withdraw the notice. This creates a paper trail showing good faith and forces the landlord to make a decision before spending court filing fees. If the UD is filed anyway, raise the defect in your Form UD-105 answer immediately.
