How to Change Proprietor Details on a Business Name Online with CAC - The Essential 2026 Guide

Introduction: Keeping Your Business Name Records Up-to-Date with CAC

As a business owner in Nigeria, registering your business name with the Corporate Affairs Commission (CAC) is a crucial first step. However, business circumstances can change, and sometimes, the personal details of the proprietor(s) or partners linked to that business name might need updating. Whether it's a change of name, address, or even the addition or removal of a partner, it is absolutely essential to ensure that your business records with the CAC are accurate and current.

The good news is that the CAC has made this process significantly easier and more accessible through its online portal. Gone are the days of endless queues and mountains of paperwork. Now, you can manage these changes from the comfort of your office or home. This comprehensive guide from BusinessHelp CONSULT will walk you through every step of how to change proprietor details on your business name online with CAC, ensuring you maintain full compliance and avoid any future complications.

Keeping your details updated is not just about compliance; it ensures that the CAC can reach you for important notifications, that your business identity is accurately reflected, and that you can seamlessly carry out other post-registration activities. Let's dive into the details.

Understanding Proprietor Details for Business Names

Before we go into the 'how-to', it's important to clarify what 'proprietor details' actually refer to in the context of a Business Name registration. Unlike Limited Liability Companies which have directors and shareholders, a Business Name (also known as an Enterprise or Sole Proprietorship/Partnership) is directly linked to its owner(s) – the proprietor(s) or partners.

• For a Sole Proprietorship: The proprietor is the single individual who owns and operates the business. Their personal details are directly tied to the business name.
• For a Partnership: The proprietors are the individuals who jointly own and operate the business. Each partner's details are registered with the CAC.

Proprietor details typically include:

• Full Legal Name (as it appears on a valid ID)
• Residential Address
• Date of Birth
• Nationality
• Gender
• Email Address
• Phone Number
• National Identification Number (NIN)
• Signature Specimen
• Passport Photograph

Any change to these pieces of information for any proprietor or partner associated with the Business Name requires an update with the CAC.

Common Reasons for Changing Proprietor Details

There are several legitimate reasons why you might need to update your proprietor details with the CAC. Understanding these will help you prepare the necessary documentation.

1. Change of Personal Name

This is a very common reason, often resulting from:

• Marriage: Many individuals, particularly women, adopt their spouse's surname after marriage.
• Divorce: Reverting to a maiden name.
• Personal Preference: A legal change of name by deed poll or affidavit.
• Correction of Error: Rectifying a misspelling or incorrect name recorded during initial registration.

2. Change of Residential Address

Moving to a new home is a frequent occurrence. Your official residential address linked to your business name must always be current for communication and compliance purposes.

3. Correction of Errors

Sometimes, mistakes happen during the initial registration process. This could be a wrong date of birth, an incorrect spelling of a name, or an erroneous identification number. It's crucial to correct these promptly.

4. Change in Contact Information

Updating your phone number or email address ensures that the CAC can easily reach you with important notices or updates regarding your business.

5. Addition or Removal of a Partner (for Partnerships)

If your Business Name is registered as a partnership, the structure might change over time:

• Adding a Partner: A new individual joins the business as a co-owner.
• Removing a Partner: A partner withdraws or leaves the business.

Each of these scenarios necessitates an official update with the CAC to reflect the current ownership structure.

Prerequisites for Online Application

Before you begin the online application process, ensure you have the following ready. Having these at hand will make the process smoother and faster.

• CAC Company Registration Number (BN): This is the unique number assigned to your Business Name during its initial registration (e.g., BN123456).
• CAC Online Portal Account: You must have a registered user account on the CAC self-service portal (services.cac.gov.ng). If you don't have one, you'll need to create it and link your existing business to it.
• Valid Means of Identification: A clear, scanned copy of any of the following, reflecting your current details:
  • National Identification Number (NIN) Slip or Card
  • Driver's License
  • International Passport
• Proof of New Address (if applicable): A recent utility bill (electricity, water, or waste bill) not older than three months, showing your new residential address. If the bill is not in your name, an affidavit confirming your residency at the address may be required.
• Passport Photograph: A recent, clear passport-sized photograph.
• Signature Specimen: A clear image of your signature on a plain white background.
• Affidavit (if required): For changes like name change, correction of errors, or if your proof of address is not in your name, an affidavit sworn at a High Court will be necessary.
• Deed of Partnership Amendment/Agreement (for adding/removing partners): A legal document outlining the changes in partnership structure.
• Payment for Filing Fees: Have your debit card or bank details ready for online payment.
• Reliable Internet Access: A stable internet connection is crucial to avoid interruptions during the application.
• Scanned Documents: Ensure all required documents are scanned clearly and saved in appropriate formats (usually PDF or JPEG) and within specified file size limits.

Step 5: Provide New Details and Upload Supporting Documents

2. You will be prompted to upload the necessary supporting documents. This is where those scanned copies you prepared earlier come in handy. Ensure each document is uploaded to its corresponding field.
3. Important: Double-check that the uploaded documents are clear, legible, and meet CAC's specified file formats and size limits. Incorrect or blurry documents are a common reason for application rejection.

Step 6: Review and Confirm Your Application

1. After entering all the new details and uploading documents, the system will typically present you with a summary of your application.
2. This is a critical step! Go through every piece of information carefully. Ensure there are no typos, misspellings, or incorrect dates. Verify that all attached documents are correct.
3. Any error at this stage can lead to rejection and delays. Make corrections as needed before proceeding.

Step 7: Make Payment for Filing Fees

Step 8: Submit Your Application

2. Go to the "Post-Incorporation Filings" or "My Applications" section to check the status of your submission.
3. The status might change from "Submitted" to "Processing" or "Query."
4. If your application is queried, it means CAC officials require clarification or additional information. Address the query promptly and accurately by providing the requested details or documents. Failure to respond to queries within the stipulated timeframe can lead to your application being abandoned.

Step 10: Download Updated Certificate/Status Report

1. Once your application is approved, the status will change to "Approved" or "Completed."
2. You can then download the updated Business Name Status Report or, in some cases, a new Certificate of Registration that reflects the changes made to the proprietor's details.
3. Save these documents securely for your records.
