What is a tail period in a broker agreement?

A tail provision, sometimes called a survival clause, is one of the less obvious parts of a listing agreement, and it can matter a great deal if your relationship with a broker ends before a sale closes. It deserves as much attention as the headline fee.

What a tail provision does

The clause keeps the broker entitled to a fee if you sell to a buyer they introduced or substantively worked with, even after the listing agreement itself has expired or been terminated. Without it, a seller could theoretically wait out the agreement and then close with a broker-sourced buyer for free.

Why brokers include one

Business sales often take longer to close than a single listing term, and a broker who introduced a buyer partway through negotiations has usually done most of the real work by the time a deal materializes. A tail provision protects that effort from being cut out at the finish line.

How tail periods are usually scoped

A well-drafted tail is limited to buyers the broker can actually identify, often through a list provided at the end of the engagement, rather than covering any buyer who eventually appears. It also has a defined end point, after which the obligation lapses entirely, rather than running indefinitely.

What to check before you sign

Ask exactly how the broker will prove a buyer was introduced by them, whether the tail applies only to buyers named on a list, and whether the tail period is shortened if you switch to a new broker. These details matter far more once a relationship has ended than while it is going well.
