A guarantor deed is the written promise a third party gives a landlord that the rent will be paid if the tenant fails to pay it. In England and Wales that promise used to be almost unlimited in time. It now has a statutory ceiling: a guarantee entered into on or after 1 May 2026 stops covering rent falling due after the tenant's death. At the same time, landlords have lost the old habit of taking six or twelve months' rent upfront, so the guarantee and the referencing file carry weight they never had to carry before. What follows sets out what a rent guarantee still reaches, where the law now cuts it off, and how to draft one that survives a challenge in the county court.
What a rent guarantor deed actually covers
A guarantee is a secondary obligation. The guarantor does not owe the rent in their own right; they promise to answer for the tenant's default, which means their liability tracks the tenant's and cannot exceed it. If the tenant successfully disputes a charge, the guarantor inherits that defence. If the tenancy ends, future rent stops accruing and the guarantee stops biting on it.
What the deed reaches beyond rent depends entirely on how it is drafted. A guarantee limited to "the rent" covers rent and nothing else. Most landlord-side documents go wider and pick up damage beyond fair wear and tear, unpaid utilities recharged under the tenancy, and the reasonable costs of recovery. Say so expressly or you will not get it.
There is a drafting distinction that decides cases and that most people signing at a kitchen table have never heard of. A guarantee falls away if the principal obligation falls away. An indemnity is a primary obligation and can survive events that would release a guarantor, including a variation of the tenancy agreed without the guarantor's knowledge. A guarantor asked to sign a document described as a "guarantee and indemnity" is signing something materially heavier than a guarantee. Read the operative clause, not the heading.
The legal framework for guarantees in England and Wales
Written form is the first hurdle. Under section 4 of the Statute of Frauds 1677, a guarantee is unenforceable unless it is in writing and signed by the guarantor or someone authorised to sign for them. An oral assurance from a parent, however sincere, gets a landlord nowhere.
Consideration is the second hurdle, and it catches more landlords than the first. Where the guarantee is given at the same time as the tenancy, the grant of the tenancy is the consideration and a simple signed agreement works. Where the guarantee is asked for later, mid-tenancy, after arrears have appeared or when an occupier is added, there is usually no fresh consideration at all. The document then has to be executed as a deed under section 1 of the Law of Property (Miscellaneous Provisions) Act 1989: made clear on its face that it is a deed, signed by the guarantor in the presence of a witness who attests the signature, and delivered. A mid-tenancy guarantee signed without a witness is very often worth nothing. That is also why a properly executed guarantor deed for a residential tenancy is the safer format even when consideration is not in doubt.
The third layer is new. Section 19 of the Renters' Rights Act 2025 inserted sections 16N and 16P into the Housing Act 1988, and both took effect on 1 May 2026. The full text sits on the legislation.gov.uk page for section 19 of the Renters' Rights Act 2025. It applies only where the guarantor became a party to the guarantee on or after the commencement date, and it applies whether or not the guarantee is in writing and whether or not it sits inside the tenancy agreement.
One more constraint. The Tenant Fees Act 2019 bans prohibited payments by tenants and by guarantors. A landlord or agent cannot charge the guarantor a referencing fee, a credit check fee or an administration fee for preparing the deed.
Death of the tenant: where the guarantee now stops
Section 16N is narrower than the headlines suggested, and the detail decides who pays. Where there is a sole tenant who dies, the guarantee has no effect so far as it guarantees rent for the period beginning with the death. The rent period in which the death falls is apportioned by days, so the guarantor answers for the days up to the death and not the days after it.
Joint tenancies work differently. Where two or more people are the tenant, the guarantee is released on death only if all of them die, or if the guarantor is a family member of the tenant who has died. The statutory definition of family member is generous: spouse, civil partner or cohabitee, and the children, grandchildren, parents, grandparents, siblings, nieces and nephews, aunts and uncles and cousins of the guarantor or of their partner, with step-siblings and half-siblings included. Once someone qualifies, they stay qualified even if the relationship later changes.
The release covers rent, and only rent. Arrears that accrued before the death remain enforceable against the guarantor, as do damage, dilapidations and any other liability the deed expressly guarantees. And none of this touches guarantees given before 1 May 2026, which continue on their original terms. A landlord holding a guarantee from 2024 and a landlord holding one from last month are in materially different positions on the same facts.
Open-ended tenancies and the end of rent in advance
Two other changes reshaped how guarantees behave in practice. All assured tenancies are now periodic with a rent period no longer than a month, so there is no fixed term to bound the guarantor's exposure. A guarantee drafted to run "for the term" now runs for as long as the tenancy runs, which could be years. Guarantors should insist on a defined exit, whether that is a longstop date, a cap expressed as a number of months' rent, or a right to give notice for future liability while remaining liable for what has already accrued.
Sections 8 and 9 of the Act removed the other cushion. Nothing can be taken from a prospective tenant before the agreement is signed, and no more than one rent period's rent can be required in advance after that. The lump sum that used to reassure landlords about applicants with thin credit files has gone, which is why underwriting has shifted onto the tenant referencing and right to rent pack and onto the guarantor's own means. Expect applicants to produce payslips and a signed contract of employment setting out pay and hours, and expect the same evidence to be asked of the guarantor.
Some relatives would rather put money in than sign an open-ended promise. Where that is the arrangement, a written loan agreement between private individuals records the terms far better than a bank transfer and a text message.
Drafting a guarantor deed that holds up
The generator walks through the decisions that matter rather than producing a generic form. You identify the landlord, the tenant or tenants and the guarantor, then confirm whether the tenancy is sole or joint, because that single answer changes how the death provisions apply. You state whether the guarantor is a family member of a named tenant, which is the trigger for release on a joint tenancy.
You then choose the scope: rent alone, or rent plus damage and recovery costs. You set any cap on liability and any notice mechanism for bringing future liability to an end, which matters now that tenancies no longer expire on a fixed date. The deed is assembled with the correct execution block, an attestation clause for the witness, and wording that makes clear on its face that it is intended as a deed. Download it in Word to adjust names and figures, and in PDF for the signing copy. Give the guarantor the tenancy agreement itself before anyone signs, and keep the original wet-ink deed.
Mistakes that cost landlords and guarantors
The most expensive error is the late guarantee. A landlord who asks for a guarantor once arrears have started, then accepts a signed sheet of paper with no witness and no deed wording, has usually created something unenforceable. Close behind it is the guarantee that nobody sent to the guarantor with the tenancy agreement, which invites an argument that they never knew what they were promising and hands them a route to challenge a later variation.
Then there are the assumptions. Landlords assume the death provisions leave everything else intact, which is true of damage but not of post-death rent. Guarantors assume the release applies to a deed signed in 2025, which it does not. Both sides assume a guarantee ends when the fixed term ends, forgetting that fixed terms no longer exist for assured tenancies and that an unbounded guarantee simply keeps running. Finally, agents still occasionally invoice the guarantor for referencing, which is a prohibited payment carrying a civil penalty of up to £5,000 for a first breach.
Frequently asked questions
Does a rent guarantor deed need to be signed as a deed to be valid?
Not always. A guarantee given at the same time as the tenancy is supported by consideration and needs only writing and the guarantor's signature under section 4 of the Statute of Frauds 1677. A guarantee given later usually lacks consideration and must be executed as a deed, signed in the presence of a witness who attests it. Because the timing is easy to get wrong, most landlords now use a deed of guarantee for residential lettings in every case.
Is a guarantor still liable if the tenant dies?
For rent falling due after the death, no, provided the guarantee was entered into on or after 1 May 2026 and the tenant was the sole tenant. The rent period in which the death falls is split by days. Everything else stands: arrears accrued before the death, damage, and any other liability the deed expressly covers. Guarantees signed before that date are unaffected.
Does the guarantor cover the other joint tenants' rent?
Usually yes, unless the deed says otherwise. Joint tenants are jointly and severally liable for the whole rent, so a guarantee of "the tenant's" obligations picks up the full sum, not one share of it. A guarantor who intends to stand behind one person only should insist on wording that caps liability to that individual's proportion of the rent and of any damage.
Can a landlord charge a guarantor a referencing fee?
No. The Tenant Fees Act 2019 applies to payments demanded from guarantors as well as tenants, and referencing, credit checks and tenancy setup charges are all prohibited payments. Only rent, a capped tenancy deposit, a capped holding deposit, certain default fees, tenant-requested variations and early termination payments are permitted. A first breach attracts a penalty of up to £5,000, and a further breach within five years rises to £30,000.
How long can a landlord pursue a guarantor for unpaid rent?
Six years from the breach where the guarantee is a simple contract, under section 5 of the Limitation Act 1980, and twelve years where it was executed as a deed, under section 8. Each missed payment starts its own clock, so an old arrears file can contain both time-barred and live instalments. Executing as a deed doubles the recovery window.
What happens if the tenant falls three months behind on rent?
Ground 8 requires at least three months' arrears for monthly-paid rent, both when the notice is served and at the hearing, with four weeks' notice before proceedings. Section 21 was abolished on 1 May 2026, so possession runs through a section 8 notice seeking possession on a stated ground. Notify the guarantor in writing as soon as arrears appear rather than at the point of issue.
Which format should the guarantor deed be downloaded in?
Both. Word lets you adjust names, the rent figure, any liability cap and the notice provisions before printing. PDF gives you the clean signing version. A deed has to be signed on paper in the presence of a witness who signs and prints their own name and address, so print the PDF, execute it, and keep the original safe alongside the tenancy agreement.
