Special terms carry the same force as the contract body
Clearly defining the specific circumstances of your deal as special terms -- things a standard template can't anticipate -- meaningfully reduces the risk of disputes later. This is general information, not legal advice, so review the actual wording with a licensed real estate agent or lawyer.
The same idea applies to rental agreements
If you're curious how special terms are handled in a rental agreement instead, our guide to the basics of writing a residential lease covers similar ground for tenants and landlords.
Frequently Asked Questions
Is there a limit to how many special terms I can include?
There's no fixed limit, but rather than listing everything you can think of, it's more effective to clearly spell out the handful of points that actually matter for this specific deal.
Does a verbal agreement count if it isn't written down?
A verbal agreement can carry legal weight in principle, but it's difficult to prove if a dispute arises, which puts you at a disadvantage. Any agreement that matters should be written into the contract as a special term.
