Forfeiture: Can a Freeholder Take Back Your Flat?
Forfeiture is the freeholder's right to terminate a lease and repossess the flat for a serious breach. In practice it is rare, but the threat of forfeiture proceedings can affect a sale. This guide explains how the process works and what protections leaseholders have.
Forfeiture in Plain English
A leasehold is a contractual arrangement: the leaseholder pays ground rent (on older leases), service charges and complies with the covenants in the lease in exchange for the right to occupy the flat for the term. If the leaseholder seriously breaches those obligations, the lease gives the freeholder the right to forfeit the lease, which means terminating it and repossessing the flat.
The word forfeiture comes from the idea that the leaseholder forfeits (loses) their interest in the property. The practical consequence is severe: the leaseholder loses all of the equity they have built up over years or decades of ownership, not just the amount of the debt that triggered the proceedings. A leaseholder with a flat worth £400,000 and ground rent arrears of £500 on an older lease could, in theory, lose everything.
Partly for this reason, the law surrounds forfeiture with significant procedural protections for leaseholders: the landlord must follow the statutory process, and the leaseholder, a mortgage lender or another person with an interest in the lease may be able to apply for relief where the breach can be remedied and the leaseholder acts promptly. Completed forfeitures of residential flats are rare. But threatened or actual forfeiture proceedings are not, and they have real practical consequences, particularly for anyone trying to sell, and the financial consequences can be serious if the leaseholder does not respond promptly.
The protections against forfeiture
Forfeiture is a severe remedy, but a leaseholder is far from defenceless. A freeholder has to clear each of the protections below before a flat can actually be lost.
The £350 / three-year threshold
Small or recent arrears of ground rent, service or admin charges cannot, on their own, trigger forfeiture.
The breach must be proven
For most breaches it must be admitted, or determined by a court, tribunal or arbitrator.
A formal notice, with time to put it right
A section 146 notice must set out the breach and give a reasonable chance to remedy it.
The court's discretion
A court will not forfeit automatically, and usually gives the leaseholder a chance to pay or comply.
Relief from forfeiture
The leaseholder can ask the court to restore or preserve the lease, usually on terms.
The lender's safety net
A mortgage lender may step in and apply for relief to protect its security.
What Can Trigger Forfeiture Proceedings
The right to forfeit must be set out in the lease. A landlord can only pursue forfeiture where the lease contains an appropriate forfeiture or re-entry clause and the conduct complained of amounts to a breach covered by that clause, so the wording of the individual lease must always be checked. Most residential leases include a forfeiture clause that allows the freeholder to re-enter the property if the leaseholder fails to pay rent or service charges, or breaches any of the other lease covenants. The most common triggers in practice are the following.
Ground rent arrears
For leases granted before 30 June 2022, ground rent is often payable annually or quarterly, and non-payment is a breach of the rent covenant. But ground rent does not normally become payable unless the landlord has served a valid notice under section 166 of the Commonhold and Leasehold Reform Act 2002: the notice must be in the prescribed form and give the leaseholder the required period to pay, so an ordinary invoice or informal request may not be enough. The same Act also restricts forfeiture for small or recent debts. A landlord cannot normally forfeit for unpaid ground rent, service charges or administration charges unless the total exceeds £350, or some part has been outstanding for more than three years. The £350 can combine all three types of charge, and a landlord cannot avoid the restriction by treating each separately. Even where the total is £350 or less, forfeiture may still be available if part of the debt is more than three years old.
For most qualifying new leases granted on or after 30 June 2022, the Leasehold Reform (Ground Rent) Act 2022 restricts ground rent to a peppercorn, which has no financial value; the restriction applied to qualifying retirement housing leases from 1 April 2023. There are limited exceptions, including certain business, community-housing and home-finance leases, and some voluntary lease extensions may keep the existing ground rent until the original term of the lease expires. The date of the lease alone does not always determine whether ground rent can lawfully be charged.
Service charge arrears
Service charges (the annual costs of maintaining the building, insuring it, and providing communal services) must be paid under the lease. A landlord cannot normally pursue forfeiture for unpaid service charges or administration charges unless the amount has been admitted by the leaseholder or finally determined by a court, the appropriate tribunal or a qualifying arbitration process. Once the amount has been determined, the landlord must also allow the statutory 14-day period to expire before taking forfeiture action, including serving a section 146 notice. The £350 and three-year restriction above applies here too.
Breach of a lease covenant
Subletting without consent where the lease requires it, carrying out alterations without a licence to alter, keeping a pet where prohibited, using the flat for a business where residential use only is permitted or causing persistent nuisance to neighbours can all amount to breaches of lease covenants that could theoretically support forfeiture proceedings. In practice, freeholders rarely pursue forfeiture for minor covenant breaches unless there is a persistent pattern of non-compliance or a serious ongoing breach.
A landlord can also lose, or waive, the right to forfeit for a particular breach by acting in a way that treats the lease as continuing after becoming aware of the breach, such as demanding or accepting later rent. Waiver is legally complex and turns on the landlord's knowledge and conduct.
The Legal Process
Forfeiture does not happen immediately when a breach occurs. There is a formal procedural path the freeholder must follow, and at each stage the leaseholder has the opportunity to remedy the situation.
Before a landlord can serve a section 146 notice for most breaches of a long residential lease, the breach must normally have been established. This can happen where the leaseholder admits the breach, where a court or tribunal makes a final decision that the breach occurred, or where an arbitrator makes a qualifying determination. The requirement can apply to breaches such as unauthorised alterations, unlawful subletting, nuisance and failure to comply with other lease covenants, not only service charge disputes.
The forfeiture process, step by step
Forfeiture follows a set sequence rather than happening all at once, and at several points the leaseholder can stop it by putting the breach right. This is how a case typically moves from a breach to a possible application for relief.
-
A breach occurs
Unpaid ground rent or service charges, or a breach of a lease covenant such as unauthorised alterations or subletting.
-
The breach is established
For most breaches other than rent, the leaseholder admits it or a court, tribunal or arbitrator determines it. Service and admin charges must be determined, then a 14-day period passes.
-
Formal notice
A section 146 notice sets out the breach and a time to put it right (a section 166 notice is what makes ground rent payable). The £350 and three-year limit also applies to arrears.
-
A chance to remedy
The leaseholder pays the arrears or fixes the breach. Many cases end here, with no further action.
-
Court proceedings
If it is not resolved, the freeholder applies to the County Court. Changing the locks on an occupied flat is not a lawful shortcut.
-
Relief from forfeiture
The leaseholder, or their mortgage lender, can ask the court to restore the lease, usually on terms. Relief is discretionary, not guaranteed.
The section 146 notice
For breaches of covenant other than non-payment of rent, the freeholder must first serve a section 146 notice (under section 146 of the Law of Property Act 1925) before they can begin forfeiture proceedings. The notice must identify the breach, require it to be remedied if it is capable of remedy, and require the leaseholder to pay reasonable compensation. The leaseholder must then be given a reasonable period of time to comply. Only if they fail to do so can the freeholder proceed. Serving a section 146 notice does not by itself end the lease or transfer ownership of the flat to the freeholder: the lease continues unless it is lawfully forfeited through the proper procedure, surrendered by agreement, or otherwise brought to an end, and if the matter is not resolved the landlord will normally need to bring court proceedings.
For service charge or administration charge arrears, the amount must first be admitted or finally determined by a court, the appropriate tribunal or a qualifying arbitration, and the statutory 14-day period must then pass, before the landlord serves a section 146 notice or takes other forfeiture action. A disputed charge cannot be the basis of a forfeiture notice until it has been resolved in this way.
Some lease breaches can be remedied, such as paying arrears or reversing unauthorised works. Others may be regarded as incapable of remedy, depending on their nature and consequences. Even where a breach cannot be remedied, the court may still have power to grant relief from forfeiture on appropriate terms, so there is no fixed list of breaches that are always capable or incapable of remedy.
County Court proceedings
If the leaseholder does not remedy the breach after a valid section 146 notice, the freeholder can issue proceedings in the County Court for forfeiture. The court does not automatically grant forfeiture: the leaseholder has the right to apply for relief (see below), and the court will usually give the leaseholder the opportunity to pay any outstanding sums and remedy the breach before making any order.
Peaceable re-entry
There is in theory a second route to forfeiture without court proceedings, called peaceable re-entry, where the freeholder physically re-enters the property and changes the locks. Where a person is lawfully living in the flat, the landlord cannot enforce forfeiture this way: doing so could amount to unlawful eviction under the Protection from Eviction Act 1977, with serious legal consequences. The position can be more complicated where a property is genuinely vacant, but peaceable re-entry of a residential flat remains legally risky, and a landlord should obtain specialist legal advice before attempting it.
Relief from Forfeiture
Relief from forfeiture is the leaseholder's most important protection. It is a court order that can restore or preserve the lease even though a forfeiture has been established, usually on conditions such as remedying the breach, paying the arrears and paying the landlord's reasonable legal costs. The County Court has a broad discretion. Courts frequently grant relief where the breach is remedied and the leaseholder acts promptly, but relief is discretionary and should never be assumed.
How the leaseholder applies
Once forfeiture proceedings have been issued, the leaseholder can apply to the same court for relief. The court will often grant relief on terms: the leaseholder pays the outstanding arrears, costs, and any other sums due, within a specified period, and if they comply the lease is restored and continues as if the forfeiture had not occurred. In deciding, the court may consider the circumstances of the breach, whether it has been remedied, the conduct of both parties, the effect of forfeiture and how promptly the leaseholder applied for relief.
Special procedural rules can apply where the proceedings are based on non-payment of rent. In some cases, paying the full arrears and costs before the court hearing can bring the proceedings to an end. If a possession order is made, the leaseholder may still be given a period in which to pay, and a leaseholder may sometimes apply for relief even after the landlord has recovered possession, although strict time limits can apply. None of this is automatic: the procedure depends on the type of proceedings and the circumstances, so urgent legal advice should be taken.
The amount required to resolve a forfeiture dispute may be more than the original debt. The leaseholder may also have to pay interest, administration charges and the landlord's reasonable legal costs, subject to the lease and any applicable statutory controls. Those costs and charges may themselves be open to challenge before a court or tribunal.
The mortgage lender's right to apply
A mortgage lender may also be entitled to apply for relief from forfeiture to protect its security, separately from the leaseholder's own application. Many modern leases contain a mortgagee protection clause requiring the landlord to notify the leaseholder's lender before taking forfeiture action, although this may depend on the landlord having previously received formal notice of the lender's charge, and the precise requirements depend on the wording of the lease and the circumstances (which is why the Notice of Charge on a mortgaged leasehold matters). A lender may decide to intervene where forfeiture threatens its security: it might pay the arrears, fund an application for relief or require the leaseholder to resolve the breach. A lender is not required to intervene in every case, so intervention should not be assumed.
Time limits for applying
Applications for relief must be made within a reasonable time. Where forfeiture has been completed by a court order, there are strict time limits for applying. For residential property, the courts have historically been prepared to hear applications even after some delay if the circumstances justify it, but leaseholders should not assume that late applications will automatically succeed. Anyone who receives a breach notice, section 146 notice, tribunal application or possession claim should obtain specialist legal advice immediately: deadlines can be short, and delay can make it harder or more expensive to protect the lease. A landlord considering forfeiture should equally take specialist advice before serving notices or taking possession proceedings, as serving an invalid notice, failing to obtain the required determination or attempting unlawful re-entry can cause the claim to fail and expose the landlord to legal costs or other claims.
How Forfeiture Risk Affects Selling Your Flat
For most leaseholders who are up to date with their ground rent and service charges and are not in breach of any covenants, forfeiture is not a live concern. But for those who have fallen into arrears or have received correspondence from the freeholder about a breach, the impact on a potential sale can be significant.
Disclosure requirements
A seller must answer the property information forms honestly and accurately. The current leasehold form is the Law Society TA7 Leasehold Information Form, fifth edition, which is mandatory for Conveyancing Quality Scheme members from 30 March 2026. Relevant breaches, disputes, notices and forfeiture proceedings may need to be disclosed through more than one route: the TA6 form, the TA7 form, the landlord's management pack, replies to the buyer's additional enquiries or directly through the seller's conveyancer. A section 146 notice or other formal correspondence about a breach must be disclosed; non-disclosure is a misrepresentation risk, and the buyer's solicitors will in any case ask for copies of all correspondence with the freeholder as part of their due diligence.
Impact on mortgage availability
An unresolved breach, a section 146 notice or a forfeiture claim is likely to make mortgage lending extremely difficult. The buyer's conveyancer will normally need to report the issue to the proposed lender, and the lender's response will depend on its own requirements, the seriousness of the breach and whether the matter can be formally resolved before completion. There is no universal clean period after which a flat automatically becomes mortgageable again; a lender may instead require written confirmation that the breach has been remedied, the notice withdrawn, the proceedings ended and any legal costs paid, and requirements vary between lenders.
Selling with unresolved forfeiture risk
A flat can sometimes be sold while a lease dispute or forfeiture issue is being resolved, but the matter is likely to concern the buyer's conveyancer and mortgage lender. In practice, the breach will usually need to be remedied and any notice or court proceedings formally withdrawn or concluded before a conventional mortgage-funded sale can complete. Paying the arrears, remedying the breach and paying the landlord's reasonable costs may stop the proceedings or support an application for relief, but the result depends on the stage reached, the type of breach and any orders the court has already made, so it cannot be guaranteed.
Cash buyers who are experienced with leasehold complications are better placed to assess and price in forfeiture risk than buyers relying on a mortgage. Where arrears are modest and the breach is remediable, a cash buyer may proceed where a mortgaged buyer cannot. Where the situation is more serious, obtaining legal advice and resolving the breach first is usually the better course.

Frequently Asked Questions
Forfeiture is the legal process by which a freeholder can terminate a leasehold and repossess the flat. It is triggered by a breach of the lease, typically non-payment of ground rent or service charges, or a breach of a lease covenant. The leaseholder loses their interest in the property, which makes it a very serious remedy. The law provides significant protections for leaseholders, including the right to apply to the court for relief (an order restoring the lease), and completed forfeitures of residential flats are rare in practice.
The most common triggers are arrears of ground rent or service charges. Forfeiture can also be triggered by breaches of lease covenants: subletting without consent, carrying out alterations without a licence, using the flat for a prohibited purpose, or causing persistent nuisance. The lease must contain a forfeiture clause, and the freeholder must follow a formal procedural path before proceedings can begin. For most breaches other than non-payment of rent, the breach must first be admitted or determined by a court, tribunal or arbitrator before a section 146 notice can be served.
For most qualifying new leases granted on or after 30 June 2022, the Leasehold Reform (Ground Rent) Act 2022 restricts ground rent to a peppercorn, which has no financial value, so ground rent arrears do not usually arise on those leases (there are limited exceptions). For older leases where ground rent is still charged, the landlord cannot normally forfeit for unpaid ground rent, service charges or administration charges unless the total exceeds £350, or part has been outstanding for more than three years. Ground rent also does not normally become payable unless a valid notice in the prescribed form has been served under section 166 of the Commonhold and Leasehold Reform Act 2002.
A section 146 notice is a formal written notice the freeholder must serve before beginning forfeiture proceedings for a breach of covenant (other than non-payment of rent). Named after section 146 of the Law of Property Act 1925, it must specify the breach, require the leaseholder to remedy it if capable of remedy, and require compensation for any loss. The leaseholder must be given a reasonable time to comply before the freeholder can take further action. If you receive a section 146 notice, taking legal advice immediately is essential.
Relief from forfeiture is a court order that can restore or preserve the lease even after a forfeiture has been established, usually on conditions such as remedying the breach, paying the arrears and paying the landlord's reasonable legal costs. When a freeholder commences forfeiture proceedings, the leaseholder can apply to the County Court for relief. Courts frequently grant relief where the leaseholder acts promptly and the breach is remedied, but relief is discretionary and should never be assumed. Where it is granted, the lease continues as if the forfeiture had not been brought.
A mortgage lender may be entitled to apply for relief from forfeiture and to pay outstanding arrears to protect its security. Many modern leases contain a mortgagee protection clause requiring the landlord to notify the lender before taking forfeiture action, though this can depend on the landlord having previously received formal notice of the lender's charge, which is why the Notice of Charge served at the time of the mortgage matters. A lender may decide to intervene where forfeiture threatens its security, but it is not required to in every case, so intervention should not be assumed. If you have no mortgage, there is no lender to step in, so responding promptly to any forfeiture-related correspondence yourself is critical.
An unresolved breach or active forfeiture claim must be disclosed to any buyer and is likely to make mortgage lending extremely difficult. A flat can sometimes be sold while the matter is being resolved, but in practice the breach will usually need to be remedied and any notice or proceedings formally withdrawn or concluded before a conventional mortgage-funded sale can complete. A cash buyer experienced with leasehold complications may be able to proceed where a mortgaged buyer cannot. Taking specialist leasehold legal advice immediately is essential.
Actual completed forfeitures of residential leasehold flats are rare. The procedural requirements, the right to apply for relief, and the courts' general approach to residential property mean that many proceedings end in the lease being restored or the breach being resolved, though relief is discretionary and not guaranteed. The greater practical concern is usually not losing the flat but having forfeiture proceedings started, disclosed during a sale, and causing the sale to stall while the proceedings are resolved. Clearing arrears promptly and seeking legal advice at the first sign of threatened forfeiture is the right approach.
