How to Renew a Lease the Right Way — and Avoid Problems Later
Last updated July 23, 2026
As a lease approaches its end date, both landlord and tenant usually have to decide whether to renew. Because they may have rented to each other for years, many simply agree by word of mouth and let the old contract roll on with nothing in writing — which becomes a real problem the moment a dispute arises later over rent, the deposit, repairs to fixtures, or exactly how long the renewal covers. This guide walks through what to check and the steps to take so a lease renewal goes smoothly, with clear evidence for both sides.
Why a written renewal beats a verbal agreement
Verbal renewals usually happen because both sides already know and trust each other. But trust does not help once a disagreement arises later, whether deliberate or not — different recollections of the date agreed, different understandings of who bears the cost of damage, different figures for the new rent, or one side assuming a year-by-year renewal while the other assumed an open-ended one.
Without any document, the side that cannot prove what was agreed usually loses out — a landlord who denies ever agreeing to renew, or a tenant billed a different rent than what was discussed. A written renewal that both parties sign is the clearest evidence of exactly what was agreed, and it heads off disputes from the outset.
What to check before every lease renewal
Before agreeing to renew, always pull out the original lease and re-read it in full — especially the true end date, the advance-notice period if either side does not want to renew (this runs on whatever the original contract specifies, not a fixed number of days that applies to every lease), and any other terms already agreed, such as who is responsible for which repairs.
It also helps for both sides to walk through the property together before renewing, to record its current condition. If damage occurred during the first lease term, agree clearly whether it will be repaired before renewal or accepted as-is — so the same issue does not resurface as a dispute when the new term ends.
Rent and deposit — can they change at renewal?
Renewal is the natural point for both sides to revisit rent and deposit by mutual agreement — there is no fixed rule that rent must stay the same. A landlord may propose adjusting rent to match current market conditions, and a tenant is equally free to negotiate, decline, or choose not to renew. What matters is that any change is agreed by both sides, not announced unilaterally without consent.
If the deposit is topped up to match a new rent figure, the renewal agreement should clearly state the extra amount, when it was paid, and how the combined deposit will be returned when the new term ends — so there is no confusion about the total deposit or how deductions apply.
Steps to complete a lease renewal properly
The recommended steps:
- Review the original lease and reach a rough verbal understanding of whether to renew.
- If renewing, agree on whatever details are changing — the new term length, the new rent, and the new start and end dates.
- Put the renewal in writing, clearly referencing the original lease so it reads as an extension of that specific contract, not a separate new one.
- Both parties sign the renewal agreement.
- Each side keeps a copy alongside the original lease, so that whenever it needs to be referenced later — the next renewal, or ending the lease — both sides hold the same complete set of documents.
Skipping any one of these steps is usually where later misunderstandings start.
Renewing a lease on Kontrax
On Kontrax, a lease renewal is created as a document tied directly to the original lease. The parties' names and ID numbers carry over from the original contract and stay locked, while the details that typically change at renewal — rent, deposit, and term — can be adjusted to whatever the two sides newly agree.
Once both sides have checked the details, landlord and tenant both e-sign the renewal document in the system, and it schedules a fresh reminder ahead of the new term's end date — so nobody has to keep track of the renewal date from memory.

Frequently asked questions
Is a purely verbal lease renewal enough?
It is not advisable. A verbal understanding is possible, but if the two sides later remember the new rent differently, there is no record of what was actually agreed. Always put the renewal in writing and have both parties sign it.
How many days' notice are needed before a lease expires?
It depends mainly on the original lease. Each contract typically sets its own notice period — there is no fixed number of days that applies to every lease — so always check the original document before deciding whether to renew.
Can the landlord raise the rent when the lease is renewed?
Yes, if both sides agree. Renewal is a natural point for a landlord to revisit rent, and the tenant is equally free to negotiate or decline to renew. Whatever new figure is agreed should be stated clearly in the renewal document.
Do we need to draft a whole new contract to renew a lease?
No — a renewal addendum referencing the original lease is enough. In Kontrax, a renewal is created as a document that carries over the original contract's details, with names and ID numbers locked to match the original.
What documents should be kept after renewing?
Keep the original lease, the signed renewal agreement, and evidence of any payments — such as the new rent or a top-up deposit — together as one set, so they are easy to check back on if ever needed.
