The real risk

The risk isn’t bad faith —
it’s forgetting.
And it costs dearly.

Unlawful rent review

Wrong index, wrong date, or an EPC F/G frozen dwelling: the increase can be challenged, and the tenant may refuse it.

JAREMS – per-jurisdiction calculation, dated and auditable, letter ready.

1 to 3 lease years lost

Notice served a few days late, and the lease renews itself: one year in France, up to three in Belgium.

JAREMS – alerts weeks before every key date, editable letters generated in time.

Insurance lapse

Tenant’s certificate expired, chimney sweeping forgotten: in case of fire, the insurer can refuse to cover.

JAREMS – certificates and mandatory maintenance tracked, alerts weeks before each deadline.

Warranty lost

Heat pump, boiler, AC: one missed annual service and the manufacturer’s warranty is void – the breakdown is on you.

JAREMS – reminders weeks before each service, proofs filed per property.

Cannot re-let

The EPC certificate expired: no re-letting – and no annual rent review – until it is renewed.

JAREMS – alerts weeks before the certificate expires, on every property.

Contested receipt

Missing VAT or legal mention: the document no longer holds up in a dispute.

JAREMS – receipts and invoices per lease, archived as PDF.
