What is a title defect?
A title defect is any issue with the registered ownership of a property that undermines the seller's right to sell it, creates uncertainty about who owns it, or imposes a burden that a future owner will inherit. The HM Land Registry title register is the authoritative record of title in England and Wales — and reading it correctly is the single most important legal skill for an auction buyer.
Title defects range from minor (a covenant breach that can be insured for £300) to catastrophic (a bankruptcy restriction that prevents any disposition, or a possessory title from an adverse possession claim where the original owner is known and has not been notified). At auction, buyers must make this assessment before the hammer falls.
Understanding the title register
The title register is divided into three sections:
- A Register (Property Register) — describes the property, the title number, the class of estate (freehold or leasehold), and any rights that benefit the property (such as rights of way or easements)
- B Register (Proprietorship Register) — identifies the registered owner, states the class of title (absolute, good leasehold, qualified, or possessory), and records any restrictions on the owner's power to dispose of the property
- C Register (Charges Register) — shows mortgages and charges registered against the property, and any burdens on the title including restrictive covenants, notices, and cautions against dealings
A clean title has a minimal A Register (property description and any beneficial rights), a B Register showing the current owner with absolute or good leasehold title and no restrictions, and a C Register with only the existing mortgage (which will be discharged on completion from the proceeds).
Any entry beyond this — restrictions, cautions, unusual charges, notices, or a class of title other than absolute — warrants investigation.
The most common title defects found at auction
| Defect Type | Location in Pack | Risk Level |
|---|---|---|
| Possessory title — owner cannot prove original right to property; lowest grade of title | B Register (class of title) | High |
| Bankruptcy restriction — registered owner is or was subject to insolvency proceedings; trustee in bankruptcy must consent to any sale | B Register (restrictions) | High |
| Caution against dealings — a third party has registered a caution, meaning they must be notified of any proposed dealing and may object | B Register or C Register | High |
| Restriction requiring third-party consent — the property cannot be transferred without the written consent of a named party (e.g. a management company or co-owner) | B Register (restrictions) | Medium |
| Unresolved mortgage or charge — a charge is registered in the C Register but there is no evidence it will be discharged on completion | C Register | High |
| Restrictive covenant — limits how the property can be used or developed; registered in C Register | C Register | Medium |
| Flying freehold — part of the property overhangs or underlies a different title | A Register / title plan | Medium |
| Unclear boundary — the title plan does not clearly define the boundary; risk of boundary dispute | Title plan | Medium |
| Gaps in ownership chain — missing conveyances or a break in the chain of title from the original deeds | Epitome of title | High |
| Notice of adverse claim — a third party has served a formal notice asserting a claim against the title | C Register | High |
How to read the B Register for restrictions
Restrictions in the B Register can range from benign to deal-blocking. The standard restriction requiring the consent of a lender before disposing of the property is normal and will be removed on completion when the mortgage is discharged. Unusual restrictions require investigation.
Restrictions to watch for at auction:
- Restriction requiring named third-party consent — if the third party is a company that no longer exists, or an individual who cannot be traced, obtaining consent may be impossible or very expensive
- Insolvency Service restriction — registered under the Insolvency Act 1986; means the registered owner is or was bankrupt; the Official Receiver or Trustee in Bankruptcy must consent to, or conduct, any sale
- Charging order restriction — a creditor has obtained a charging order over the property in satisfaction of a court judgment; this charge must be paid off on completion or the creditor must consent to the sale
- Matrimonial home restriction — registered under the Family Law Act 1996; a spouse or civil partner has registered a right of occupation; this must be addressed before completion can occur
Financial consequences
Title defects impose financial consequences in three ways:
- Indemnity insurance costs — for insurable defects (covenants, missing building regs, chancel liability), premiums range from £30 for simple residential policies to £5,000+ for complex commercial title defects
- Reduced buyer pool on resale — a property with a title defect will always sell for less than a comparable clean-title property, because the restricted mortgage market reduces demand
- Uninsurable risk — some defects (active adverse claims, known insolvency restrictions not yet resolved, cautions by traceable claimants) are uninsurable. These must be resolved before completion or they become the buyer's problem

What is a title defect on a property?
A title defect is anything that undermines the seller's right to sell, casts doubt on ownership, or creates a burden that the buyer inherits. Common examples include possessory title, unresolved mortgages, restrictions on the B Register, restrictive covenants on the C Register, and gaps in the ownership chain.
Can title defects be fixed?
Some can be remedied before completion (discharging a mortgage, obtaining consent from a restriction holder). Others can be insured against using legal indemnity insurance (£30–£5,000+ depending on the defect). Some are uninsurable — particularly where an adverse claim is known and active. The nature of the defect determines the remedy.
What does the title register show?
The HM Land Registry title register has three sections: A Register (property description and beneficial rights), B Register (ownership, class of title, restrictions), and C Register (mortgages, charges, restrictive covenants, and notices). A thorough read of all three is essential before bidding at auction.
What is a restriction on a property title?
A restriction in the B Register limits the registered owner's ability to deal with the property without complying with a condition — such as obtaining the consent of a named party. Standard mortgage restrictions are routine. Unusual restrictions (bankruptcy, insolvency, third-party consent requirements) need investigation and may block completion if not resolved.
What is indemnity insurance in property?
Legal indemnity insurance is a one-off premium policy protecting the buyer against financial loss from a specific title defect. Common policies cover restrictive covenants, possessory title, missing building regulations, chancel repair liability, and flying freeholds. The policy compensates against loss — it does not remove the defect. Premiums range from £30 for simple residential policies to £5,000+ for complex issues on high-value properties.
