Agency agreements: sole agency, general agency and what to check
An agency agreement is the contract between you and the agency that sells your home. Read it properly. It decides who can market your home, how long for, and when you owe commission.

It must be in writing first
There must be a written agency agreement, signed by you or on your behalf and by the agent, before the agent does any work. You are entitled to a copy within 48 hours. For a residential sale you must also be given the Real Estate Authority's agency agreement guide.
Sole agency
A sole agency gives one agency the exclusive right to market and sell your home. If you sell it privately during the agreement, you still owe that agency its commission. Signing with a second agency as well risks paying two commissions.
General agency
A general agency lets more than one agency market your home, each under its own separate agreement. The agencies must tell you if there is any risk of paying two commissions, and you should pay commission to one agency only.
Joint sole agency
Two or more agencies can also share a listing under a joint sole agency. Ask how the work and the commission are split, and that it is written into the agreement.
How long it runs, and cancelling
Every agreement needs an end date or a set length. For a residential sole agency longer than 90 days, either you or the agency can cancel after the first 90 days. You can also cancel in writing in a short window after receiving your copy: until 5.00 pm on the first working day, or five working days if the agency approached you without you asking first. Taking your home off the market does not cancel the agreement; you cancel in writing.
Some agreements keep commission payable for a stand-down period after they end, if you sell to a buyer the agency introduced. Check for it.
What the agent must explain before you sign
A written estimate of commission and how it is worked out, any rebates or commission the agent receives from others, the marketing costs, your sale options (auction, tender, advertised price), and a recommendation to get legal advice. The agent must also check your identity under anti-money-laundering rules and tell you about any conflicts of interest.

Common questions
- What is the difference between sole agency and general agency?
A sole agency gives one agency the exclusive right to market your home. A general agency lets more than one agency market it, each under a separate agreement, with commission paid to one only.
- Can I cancel a sole agency agreement?
Yes. You can cancel in writing in a short window after you receive your copy, and after 90 days of a residential sole agency longer than 90 days. Check the exact wording with your lawyer.
- Do I pay commission if I sell my home privately during a sole agency?
Yes. A private sale during a sole agency still means paying the agency its commission.
- Does an agency agreement have to be in writing?
Yes. It must be written and signed before the agent does any work, and you must get a copy.
