RTDR12112 – Updating Application Information or Adding a Claim

Jurisdiction: Country: Canada | Province or State: Alberta

What is an RTDR12112 – Updating Application Information or Adding a Claim?

This form lets you change an active RTDRS application. You can correct details, add information, or add new claims. You use it after you have a file number but before your hearing ends. It keeps your case accurate and complete for the Tenancy Dispute Officer.

You typically use this form if you are the applicant. Applicants are usually landlords or tenants. You may also be a property manager, agent, advocate, or lawyer. If you filed the original application, you are the person who can update it.

You would need this form when something changes after filing. You might learn you misspelled the respondent’s name. You might decide to add a claim for new rent arrears. You may discover new damage to the suite after move-out. You may realize the legal name of a corporate landlord is wrong. The form gives you a clear way to fix these issues.

Common use cases arise when rent continues to accrue after you filed. Landlords often add new arrears, utilities, or cleaning costs. Tenants often add claims for a larger rent abatement or for more missing receipts. Both sides update contact details or addresses for service. You can also remove a claim you no longer want to pursue. You can adjust the amount of a claim if you receive a payment before the hearing.

This form does not start a new case. It amends what you already filed. Your dispute remains under the same file number. The Tenancy Dispute Officer will consider your updates with the rest of your evidence. If accepted, your added claims become part of the hearing issues. If denied, your original application stands as filed.

When Would You Use an RTDR12112 – Updating Application Information or Adding a Claim?

You use this form when new facts appear, or you need to correct errors. For example, you filed for rent owed to the end of last month. The hearing is next week. More rent is now due. You can add the new amount with this form. You should attach a revised ledger that shows the updated balance.

You also use it when a party’s identity needs correction. You may have named “John Smit,h” but the lease shows “Jonathan R. Smith.” Precise names help with service and enforcement. If the respondent is a company, you must use its exact legal name. If you discover the correct name, file this form to update it. If you add a new respondent, you must serve them as well.

Tenants use this form when more evidence changes the scope of a claim. You might have requested the return of a security deposit only. Later, you gather proof of unlawful rent increases. You can add a claim for the overpayment. You should explain how you calculated the amount and attach supporting documents.

Landlords use this form after move-out inspections. You may find damage behind appliances or in a storage area. You can add a claim for repairs if tied to the same tenancy. You need invoices or estimates. Photos with dates help support the new claim.

Both sides use this form to fix contact details. If your email or phone number changes, update it. If the property address in the file is wrong, correct it. If you need an interpreter or have access needs, add that information. Accurate contact details help ensure notices and decisions reach you.

Sometimes you use this form to withdraw or narrow claims. You may receive a partial payment and decide to reduce the amount claimed. You can also remove items that do not fit within the tribunal’s jurisdiction. This keeps the hearing focused and fair.

Timing matters. File updates as early as possible. Late changes can cause an adjournment. The Officer may refuse late additions if they prejudice the other side. If you file close to the hearing, explain why the change could not be made earlier. Be prepared to show that you served the update promptly.

Legal Characteristics of the RTDR12112 – Updating Application Information or Adding a Claim

This form is part of the tribunal record for your file. Your statements on the form are formal. You certify that what you provide is true to the best of your knowledge. The Tenancy Dispute Officer relies on your updates to set the issues for the hearing. The form itself is not an order. However, once accepted, it shapes what the Officer can decide.

Enforceability flows from the resulting order, not the form. When your added claim is accepted and heard, it can become part of the final order. That order is binding. It can be enforced like a court judgment once issued. The tribunal’s power to issue orders depends on the Residential Tenancies framework and the tribunal’s rules. Your updates must fit within that framework.

To ensure enforceability, you must observe fairness and notice. You must serve the other party with any change that affects the issues. They must have a fair chance to respond. If you add a new claim, you should include clear calculations and evidence. Ambiguous or last-minute claims risk being refused or adjourned.

Jurisdictional limits still apply. The tribunal only hears residential tenancy disputes. It cannot deal with personal injury, defamation, or unrelated torts. It does not handle commercial tenancies. Your added claim must arise from the same tenancy. Monetary limits apply. If your added claims take you over the limit, you may need to adjust. You can waive amounts above the limit or choose another forum. You cannot split claims to avoid the limit.

Limitation periods also apply. Most civil claims must be brought within a set time. If you add an older claim, you must ensure it is still within time. If the claim is out of time, it may be dismissed. Keep your evidence and dates clear in the update.

You must follow service rules for any new or corrected party. If you add a co-tenant, you must serve that person. If you change the landlord from a trade name to a corporation, you must serve the corporation. The Officer may ask for proof of authority if you act as an agent. Attach your management agreement or written authorization if needed.

Adding certain remedies carries extra legal steps. If you add a request for termination or possession, you need to show proper notice. Attach the notice to terminate, proof of service, and any required time periods. Without proper notice, the Officer cannot grant that remedy.

In short, the form is a procedural tool. It is powerful because it shapes what the tribunal can consider. It must be used in a way that preserves fairness, jurisdiction, and proper notice. When used properly, it allows the Officer to issue a clear, enforceable order on all live issues.

How to Fill Out an RTDR12112 – Updating Application Information or Adding a Claim

Start by gathering your file number, the original application, and your hearing date. Collect any new evidence. This includes rent ledgers, receipts, invoices, photos, emails, text messages, inspection reports, and notices. Prepare a short, plain-language explanation of what changed and why.

Complete the form in the order below. Keep your writing clear and factual. Use dates, amounts, and names that match your evidence.

1) File information and hearing details.

Enter your RTDRS file number exactly. Add the hearing date and time if assigned. Confirm your role as landlord or tenant. If you have a representative, state their name and contact information.

2) Applicant information.

Provide your full legal name. If you are a corporation, use the exact legal name. Include your mailing address, phone number, and email. If you have moved or changed contact details, make that clear. If you want all correspondence to go to your representative, indicate that. If you act as a property manager, note your authority to act.

3) Respondent information.

List the respondent’s full legal name. Correct any spelling errors. If the respondent is a company, use its legal name, not a trade name. If you need to add a respondent, write the full name and address for service. Explain why you are adding them, such as a co-tenant named on the lease. If you need to remove a respondent, explain why they were named in error.

4) Tenancy details.

Confirm the rental property address, including unit number. State the tenancy start date and, if applicable, end date. State the monthly rent and payment due date. Confirm the security deposit amount and the date paid. If utilities are part of your claim, note which ones the tenant is responsible for. Keep details consistent with your lease and ledgers.

5) Select the type of update.

Indicate whether you are:

• Correcting or updating information, and/or
• Adding a new claim, and/or
• Modifying or withdrawing an existing claim.

If you are only correcting contact details, say so. If you are adding claims, list each claim separately.

6) Describe each update clearly.

Use short headings such as “Name Correction,” “Address Update,” or “Additional Rent Arrears.” Provide a one or two-sentence explanation per item. Example: “Correct respondent’s name to Jonathan R. Smith as shown on the lease.” Example: “Add rent arrears for May 1 to May 31, 2025, $1,200.”

7) For each added claim, provide details.

State the remedy you seek. If you seek money, state the amount. Show your calculation. Include dates, rates, and credits. Example: “Additional rent arrears: April 15–April 30, 2025. Daily rent $40. 16 days x $40 = $640. Payment of $200 received April 20. Balance claimed $440.”

If you seek the return of the security deposit, state the deposit amount, any deductions, and why the deductions are not justified. If you seek compensation for damage, attach photos, estimates, and receipts. Link each piece of evidence to the claim with labels, such as “Exhibit A1: Photo of damaged door, dated May 2.”

8) Update the remedies summary.

Provide a revised total for all claims. Break down the totals by category, such as rent, utilities, repairs, cleaning, or deposit. If you are reducing an amount due to a recent payment, show the new total. If you apply the security deposit as a set-off, show the calculation and remaining balance.

9) Evidence list.

Create a simple index of new attachments. Number them in order. Use clear labels. Example:

• A1: Updated rent ledger to June 30.
• A2: Screenshot of e-transfer receipt dated June 5.
• A3: Move-out inspection report dated May 1.
• A4: Invoice from ABC Repairs dated May 7.

Make sure each document is readable. Redact sensitive information not needed for the hearing, like full bank account numbers. Keep the dates visible.

10) Service plan and proof.

State how you will serve this update to the other party. Use a method allowed by the tribunal. Aim to serve as soon as possible. If you add a new respondent, serve them with the original application and the update. Keep records of how and when you served. You will likely need to file proof of service. If you use email, ensure you have consent or permission to serve that way.

11) Declaration and signature.

Read the certification statement on the form. Sign and date. If filing electronically, follow the signature instructions. Use your typed name if permitted. If you sign on behalf of a company, add your title. If you are an agent, confirm you have authority. False statements can affect your case.

12) Submit the form.

File it through the same channel you used for your application. Submit it early enough to allow the other side to respond. Keep a copy for your records. Do not send originals of receipts. Bring originals to the hearing if requested.

13) After submitting, serve the other party.

Send them the updated form and any new evidence. Include the revised remedies summary. File your proof of service with the tribunal. If time is short, be ready to explain how the other party still had a fair chance to review.

14) Prepare for the hearing.

Update your witness and document list to match the new claims. Prepare to explain why you added the claim now. Be concise. Focus on facts, dates, and numbers. Have your calculations ready to show. Organize your exhibits to match your update.

Practical examples can help you frame your update. A landlord may add rent that accrued after filing. They attach a revised ledger and a copy of the lease. They explain missed payments and partial credits. They add a cleaning invoice discovered after move-out. They update their phone number for the hearing.

A tenant may add a claim for loss of quiet enjoyment due to prolonged repairs. They attach dated photos, emails to the landlord, and a calendar of outages. They update their mailing address and request an interpreter. They reduce their security deposit claim after receiving a partial return.

Avoid common mistakes. Do not add claims that are unrelated to the tenancy. Do not exceed the tribunal’s monetary limit without addressing it. Do not rely on estimates without context if a final invoice is available. Do not change party names without evidence. Do not forget to serve the other side. Do not wait until the last minute unless truly unavoidable.

If your update materially changes the case, consider asking for more time. This allows both sides to prepare. An adjournment is more likely if the change is late and large. If you oppose an adjournment, be ready to show why the other side is not prejudiced.

Use plain language throughout. Avoid long narratives. Tie each claim to a date and a document. Keep calculations transparent. That helps the Officer follow your logic. It improves your credibility and supports a clean, enforceable order.

Finally, remember that this is your record. The form, attachments, and proof of service form the backbone of your case. A clear, timely update often makes the difference between confusion and a focused hearing. Fill it out carefully, serve it promptly, and align your evidence to your requests.

Legal Terms You Might Encounter

• Applicant and Respondent refer to the two sides in your file. You are the applicant if you filed the original application. The other side is the respondent. On RTDR12112, you must list both exactly as they appear in the main file. If names or contact details changed, you use this form to correct them.
• An Amended Application is your updated filing. RTDR12112 creates this amended version. It sits with your original application under the same file number. You use it to correct facts, add information, or expand your claims. It does not erase your original claims unless you clearly withdraw them.
• An Additional Claim is a new remedy or amount you add to your existing case. You use RTDR12112 to make that addition. Examples include rent that became overdue after you filed, or a damage invoice that arrived later. You must explain what is new, why it matters, and how you calculated the amount.
• Evidence is any document, photo, statement, or record that supports your claims. When you add a claim, you usually add supporting evidence. Use RTDR12112 to identify the new evidence and how it links to your claim. Keep your evidence organized and labeled so the decision-maker can follow your story.
• Service means giving the other party a copy of what you filed. If you update your application or add a claim, you often must serve the changes. The goal is fairness. The respondent should have time to review and respond. Follow acceptable methods of service for your case. Keep proof that the service happened.
• Proof of Service is your record that the other party received your documents. It can be a sworn statement, delivery confirmation, or another accepted record. If the updated application is contested, you may need to prove service. Keep dates, addresses, methods, and who received the documents.
• Remedy is what you ask the decision-maker to order. Examples include payment of money, repairs, or return of a deposit. On RTDR12112, you list any new remedies you seek and the facts that support them. Keep each remedy clear and separate. State the dollar figure where possible.
• Notice of Hearing is the document that tells you the date, time, and format of the hearing. When you add a claim, the hearing date may or may not change. RTDR12112 does not always trigger a new hearing date. If time is short, you may need to request an adjournment to allow service and review.
• Adjournment is a new hearing date. You may request it if the added claim or updated evidence needs more time. An adjournment is not automatic. You must explain why more time is fair and necessary. If granted, the schedule shifts for everyone in the file.
• Withdrawal means removing a claim from your application. If you add a claim, you can also withdraw one that no longer applies. RTDR12112 lets you make that change clear for the record. If you withdraw a claim, state it plainly so there is no confusion at the hearing.

FAQs

Do you need to pay another fee when you use RTDR12112 to update information?

You usually do not pay a second base filing fee to correct information. You may pay a fee if you add a claim that increases the amount or scope of your case. You may also face fees if the update requires new service by a third party. Ask yourself: am I fixing details, or expanding remedies? Fee rules often turn on that difference. Budget for service costs regardless.

Do you need a new hearing date if you add a claim on RTDR12112?

Not always. Adding a claim does not automatically change the hearing date. The key issue is fairness. The other party must have time to receive and review the new material. If the schedule is tight, request an adjournment early. Explain why the added claim needs more time. If the claim is small and simple, the hearing may proceed as set.

Can you use RTDR12112 to add a new respondent?

You may correct a respondent’s legal name or address with this form. Adding a truly new party is different. That can change the scope of the file. If you need to name a different legal entity, confirm that the file still fits the same dispute. If it does, explain clearly why the new party belongs in the case. You must serve the new party. Track proof of service.

Do you need to serve the respondent with the amended application and the added claim?

Yes. If you change facts or add remedies, serve the updated application and any new evidence. Use an acceptable service method. Record how and when you served the respondent. Keep delivery confirmations. At the hearing, you may need to show that the other side received everything in time.

How late can you file RTDR12112 before the hearing?

File as early as you can. Aim to meet the disclosure deadline set for your case. If you file late, you risk the new claim being refused or the evidence excluded. The decision-maker can allow late materials, but there must be a good reason. If you foresee delay, request an adjournment and explain why it is necessary.

Can you correct simple typos without using RTDR12112?

Minor typos that do not affect service or the substance of your claim may be handled informally. If a typo affects a name, address, amount, or date, use RTDR12112. Clear records prevent delay at the hearing. If in doubt, file the update so the case file is accurate.

What happens if the respondent does not receive the updated claim?

If service fails, the hearing may not cover the new claim. The decision-maker can limit the hearing to what was served. You may be asked to re-serve and return on a new date. Avoid this by confirming addresses, using reliable service methods, and keeping proof. If service is contested, your records will matter.

Can you withdraw a claim on RTDR12112 and add a different one?

Yes. You can withdraw a claim and add a new one in the same update. Make the changes unmistakable. Label what is removed and what is added. Explain why the shift is needed and add supporting evidence. Serve the amended application and evidence so the respondent understands the new scope.

• Not using the correct file number. Your update may not reach the right case. Don’t forget to copy the file number exactly as shown on your notices.

What to Do After Filling Out the Form RTDR12112 – Updating Application Information or Adding a Claim

1. File your updated application. Submit RTDR12112 to the office handling your case. Ask for confirmation that it is linked to your file. Keep that confirmation with your records.
2. Serve the amended application. Provide the respondent with your update and any new evidence. Use a reliable method. Record the date, time, and how you served the documents. Keep delivery confirmations.
3. Update your evidence package. Insert new exhibits into your binder or digital folder. Use clear labels, dates, and short descriptions. Create or update an exhibit list so the decision-maker can track each item.
4. Review your remedies. Confirm each claim is clear, with amounts and calculations. Note any claims you withdrew. Prepare a one-page summary of what you now seek and why.
5. Assess timelines. Check the hearing date against your service date. If the respondent needs more time to review the new claim, consider an adjournment request. Tie your request to fairness and the scope of the update.
6. Plan your hearing. Update your opening statement to match the amended application. Outline the order of witnesses and the exhibits each will reference. Prepare a short closing that connects the evidence to each remedy.
7. Communicate with the other party. Confirm receipt and ask if they need any missing pages or exhibits. Document all communications. If you reach a settlement on a claim, record the terms and consider withdrawing that part.
8. Keep your file organized. Store copies of the amended application, proof of service, evidence, and all notices. Use consistent filenames or labels so you can retrieve items quickly at the hearing.
9. Be ready to update again if needed. If new facts arise, you can file a further update. Watch the calendar. The closer you get to the hearing, the harder it is to add new claims without delay. Consider whether the new issue belongs in a separate file.
10. Follow up after the hearing. If the order refers to “the application as amended,” ensure the order reflects your changes. If any part is unclear, request clarification through the available process.
