How to Write an Addendum

Step 1: Identify the Original Contract or Application

Start by clearly referencing the original contract, law school application, or agreement you are amending. This could be an employment agreement, a law school application, or any other formal contract.

Step 2: State the Purpose of the Addendum

Clearly articulate the reason for the addendum, whether it's to address a criminal record, a family emergency, academic probation, or other significant changes or details not included in the original document.

Step 3: Provide Detailed Explanations

If the addendum is for a law school application, explain circumstances like a bad semester, withdrawal from classes, or transcript issues. For contractual amendments, detail the specific changes to contractual terms, such as employment terms or purchase contracts.

Step 4: Keep It Concise and Focused

Ensure that your addendum is direct and to the point, avoiding unnecessary emotive language or exaggerated details. Aim for a one-page addendum that clearly addresses the specific issue or change.


Step 5: Review and Revise

Check for grammatical errors, clarity, and consistency with the original agreement. Consider having an admissions counselor, attorney, or admissions committee member review it, especially for law school addendums or complex legal agreements.

Step 6: Format Correctly and Add Signature Block

Adhere to the same formatting as the original document, including a signature block for mutual assent. For law school applications, align with the application package guidelines.

Step 7: Submit the Addendum

For law school applications, include the addendum with your application materials, ensuring it complements your personal statement and other documents. For contractual addendums, attach it to the original contract, maintaining a professional tone throughout.

When to Use an Addendum

An addendum is used in various situations, primarily to add to, modify, clarify, or override original terms in a legal document or contract. Key instances when an addendum is typically used include:

  1. Contract Modifications: When parties involved in a contract agree to make changes after the original document is signed, an addendum is used to outline these modifications without rewriting the entire contract.

  2. Law School Applications: Applicants may use an addendum to provide additional context or explanations for certain aspects of their application, such as discrepancies in academic performance, gaps in education, or disciplinary issues.

  3. Real Estate Transactions: In real estate, addendums are often used to change purchase terms, add contingencies, or clarify details about the property or terms of sale.

  4. Employment Agreements: If terms of employment change, such as job responsibilities, salary, or benefits, an addendum can formally document these adjustments.

  5. Legal Compliance: To address changes in laws or regulations that impact the terms of a contract, an addendum can be used to ensure compliance without needing to draft a new contract.

  6. Updating Information: If there’s a need to update or correct information in the original document, like a name change or an incorrect date, an addendum serves this purpose.

  7. Clarifying Ambiguities: When certain terms or clauses in the original contract are ambiguous or open to multiple interpretations, an addendum can provide clarity.

Addendum: Best Practices

Best practices for writing an addendum, particularly for law school applications or contractual amendments, include:

  1. Be Concise: Keep the addendum short and to the point, ideally not more than one page. Focus on providing only the necessary details.

  2. Be Clear and Specific: Clearly state the purpose of the addendum and be specific about the details or circumstances you are addressing.

  3. Avoid Emotive or Exaggerated Language: Use a professional and neutral tone. Avoid overly emotive or exaggerated language that could detract from the factual basis of your addendum.

  4. Provide Context for Issues: If addressing issues like academic probation, a criminal record, or a gap in your education or employment, provide context to help the admissions committee or the other party understand the situation.

  5. Include Relevant and Supporting Details: If applicable, provide specific dates, events, or figures that are relevant to the information being added or amended.

  6. Maintain Consistency with the Original Document: Ensure that the information in the addendum does not contradict what is stated in the main application or original contract.

  7. Review for Grammatical Accuracy: Check for grammatical errors and spelling mistakes to maintain professionalism and clarity.

  8. Attach to the Original Document: Attach the addendum to the original application or contract, and reference the specific parts of the original document it relates to.

  9. Use a Signature Block: Include a signature block in the addendum to formally validate it, using an electronic or digital signature if submitting electronically.

  10. Seek Legal or Professional Advice: Especially for contract addendums, consider getting a review by an attorney to ensure legal compliance and proper formulation.
