A more thorough explanation:

In landlord-tenant law, a notice to quit is a written notice from a landlord to a tenant demanding that they vacate the premises within a certain amount of time. The specific circumstances under which a landlord can issue a notice, the manner in which it should be provided, and the amount of time given to the tenant before they must vacate are governed by state statutes.

For example, in New Jersey, a landlord can issue a notice to quit in the following circumstances:

• When a tenant holds over and continues to occupy the premises after their lease has expired
• When a tenant holds over after defaulting on rent payments
• When a tenant behaves in a disorderly manner, damages the property, or violates the lease agreement

The notice must be served personally to the tenant or left at their usual place of abode with a family member over the age of 14. The amount of time given to the tenant before they must vacate depends on the type of tenancy they have. For example, a tenant with a month-to-month tenancy must be given one month's notice, while a tenant with a tenancy at will or from year to year must be given three months' notice.

It's important to note that a landlord must provide a valid notice to quit before beginning the eviction process.

In some cases, notice to quit may also refer to a notice from the tenant to the landlord informing them of their intent to vacate the premises.

These examples illustrate how a notice to quit is used in landlord-tenant law. They show that a landlord can only issue a notice to quit under certain circumstances and must follow specific procedures for serving the notice and providing the tenant with enough time to vacate. The examples also demonstrate that a tenant can provide notice to quit as well, indicating their intent to vacate the premises.
