C of O, Deed of Assignment, Survey: What Do These Actually Mean?
Every land listing in Nigeria comes with a title type attached, such as C of O, Survey, or Deed of Assignment, sometimes more than one at once. Most first-time buyers nod along without really knowing what separates them, or why one plot costs twice as much as another with the exact same size and location, purely because of the paperwork attached.
Here's the plain-English breakdown.
Survey (Survey Plan)
A Survey is the most basic document in Nigerian land transactions. It's a professionally prepared plan showing the exact boundaries, dimensions, and coordinates of a plot, usually approved by the state's Surveyor-General.
What it proves: the land has been measured and plotted correctly. What it doesn't prove: that the seller actually owns it, or that the land is free of disputes.
A Survey is a necessary starting point, but on its own it's the weakest form of documentation. Plenty of scams involve a genuine-looking Survey attached to land the seller has no real right to sell.
Deed of Assignment
A Deed of Assignment is the legal document that transfers a seller's interest in a piece of land to the buyer. When you buy land and receive a Deed of Assignment, you're getting documented proof that the previous owner's rights have been passed to you.
What it proves: a transfer of interest has legally taken place between seller and buyer. What it doesn't prove, on its own: that the seller who signed it actually had valid title to transfer in the first place.
This is the part buyers miss. A Deed of Assignment is only as strong as the root of title behind it. If you trace it back and the original seller never had clean ownership, ten Deeds of Assignment later doesn't fix that.
Certificate of Occupancy (C of O)
A C of O is issued by the state government (or the FCDA in Abuja) and is the strongest form of land title available in Nigeria. It's government-recognised proof of your right to occupy and use the land, and it's what banks, developers, and future buyers will actually ask for when the land changes hands again or is used as collateral.
What it proves: government-recognised legal right to the land. Why it costs more: the process of securing and perfecting a C of O involves state fees, documentation, and processing time, and land that already has one has effectively had that risk and cost absorbed for you.
So Which One Should You Buy?
It depends on your goal and your risk tolerance, but the general rule is: a C of O is safer than a Deed of Assignment alone, which is safer than a Survey alone. Land with a full C of O commands a higher price precisely because the ownership risk has already been resolved.
If you're buying Survey-only or Deed of Assignment land because it's more affordable, that's a reasonable trade-off; plenty of buyers do it, but it means the burden of due diligence sits more heavily on you. Trace the root of title, verify with a solicitor, and confirm the seller's documented right to sell before you pay anything.
We've applied exactly this thinking in our location guides, comparing the trade-offs in real listings like land in Gwagwalada, Abuja (which comes with a full C of O) against land in Omagwa, Rivers State (Survey title, priced accordingly lower).
Frequently Asked Questions
Which is better, C of O or Deed of Assignment? A C of O is generally the stronger title, since it's government-issued and recognised proof of your right to the land. A Deed of Assignment shows a legal transfer of interest but should still be checked against the original root of title.
Can I get a C of O for Survey-only land? In many cases, yes, but it requires going through the state's title perfection process, which involves fees, documentation, and processing time. Some buyers purchase Survey-title land specifically because it's cheaper and plan to process a C of O themselves later.
Is Survey title enough to prove I own land? No. A Survey confirms the land has been measured and plotted, but it doesn't prove ownership on its own. It should always be paired with proper ownership documentation and independent verification.
Does a Deed of Assignment guarantee the seller actually owned the land? No. A Deed of Assignment only proves that whoever signed it transferred their claimed interest to you. If that person's original ownership wasn't valid, the Deed inherits that weakness. Always trace the root of title.
Why does land with a C of O cost more than Survey-only land? Because the cost, time, and risk of perfecting the title has already been absorbed before the land is listed. You're paying for that certainty upfront rather than taking on the risk and cost yourself.
The Bottom Line
None of these documents is inherently good or bad; they represent different points on a risk-and-price spectrum. What matters is knowing exactly which one you're being offered, verifying it independently rather than taking a seller's word for it, and pricing that risk into your decision.
