The guarantor gap that left a landlord exposed

The tenancy looked secure because a guarantor was in place. Confident, the landlord agreed to let the property despite some concerns over the tenant’s income. Months later, arrears built up and the guarantor was approached. But there was a problem — the guarantee form had not been properly executed as a deed, and one page was missing a signature. When challenged, the guarantor’s liability collapsed. The landlord was left with no safety net and several months of rent lost.

Guarantor agreements must meet strict requirements to be enforceable. They must usually be signed as a deed, witnessed, and clearly outline the obligations being guaranteed. Courts have thrown out cases where agreements were ambiguous, not properly witnessed, or signed before tenancy agreements were finalised. In this landlord’s case, the guarantee failed on technicalities, leaving them with no recourse against the guarantor.

The lesson is simple: guarantors can provide strong protection, but only if the paperwork is watertight. Landlords should use properly drafted deed formats, ensure all signatures are correctly witnessed, and keep originals safely filed. A guarantee that fails in court is no guarantee at all.

Have you ever relied on a guarantor agreement — and did it stand up when you needed it? What safeguards do you use to make sure they are enforceable?
