Amending and Restating a Contract

When business deals evolve, you make an amendment to reflect the change. But when you have multiple changes over time, you might be better off drafting a new, amended and restated contract.

In the business world, a contract lays out the details of an exchange between two (or sometimes more) parties. Sometimes, those details change, and you need to memorialize those changes to your agreement. For a minor change, you can either mark up the changes on the original agreement or draft a simple amendment.

However, there are times when an amendment would be either inefficient, impractical, or confusing. In these instances, you can instead fully amend and restate the original agreement.

What Is an Amendment and Restatement Agreement?

An "amendment and restatement agreement" is a new agreement that combines the original agreement (sometimes referred to as the "existing agreement" or the "prior agreement") with all amendments.

Original agreement and amendments form an amended and restated agreement

An amended and restated agreement, as its name suggests, serves two purposes:

  • It amends the original agreement.
  • It restates the final terms and conditions of the agreement by combining all amendments, however they appear (whether as a separate amendment or as a markup on the original agreement), with the still-applicable terms of the original agreement.

An amendment and restatement agreement is often referred to as an "amended and restated agreement" or as an "A&R agreement" for short. The A&R agreement becomes the parties' new, binding agreement. The amended and restated agreement replaces the original agreement.

Amendment and Restatement Agreements vs. Amendments

Using a quick amendment to modify an agreement certainly has its appeal. Amendments usually require minimal effort and negotiation, and they can be signed by the parties fairly quickly. Moreover, you can repeatedly use an indefinite number of amendments to modify your original agreement.

The problem with this approach is that numerous amendments—which can result in multiple changes, additions, and deletions to the existing agreement—can either create conflicting provisions or make the document too difficult to understand. In other words, if you have too many amendments, you'll have trouble determining the parties' present rights and obligations under the business deal. In addition, the parties might either forget or misunderstand prior changes to the contract.

There's no set rule as to when an A&R agreement would be preferable to adding just one more amendment. But you might want to consider moving to an A&R agreement if:

  • you've created multiple amendment documents
  • you now have multiple cross-references that no longer align (for example, separate amendments reference provisions that have since changed or been moved), or
  • laws, legal standards, or regulatory compliance requirements have changed.

You might also simply reach a point where you think that it'd be much less confusing if all the contract changes were combined into a single document. At that moment, you should suggest to the other contract party that it probably makes more sense to incorporate the newest proposed amendments into an A&R Agreement, using the suggestions below.

Does an Amended and Restated Agreement Replace the Original Contract?

Yes. As mentioned earlier, the amended and restated agreement replaces the original agreement. The A&R agreement should now fully reflect the current understanding between the two parties. The parties should now refer to the A&R agreement for their legal rights and obligations.

How to Amend and Restate Your Contract

Amending and restating your agreement is common. Once you and the other party agree on the modifications, incorporating and consolidating these changes into a new contract is a straightforward and clarifying task. Follow the steps below to amend your prior agreement, merge the relevant terms into a new contract, and provide legal power to your amended and restated agreement.

1. Review All Existing Documents

The very first task you should complete is to carefully read through the entirety of all current documents relating to your agreement. You'll need to look at:

  • your original contract
  • all attachments to your original contract (including schedules, exhibits, and addendums), and
  • all subsequent amendments to your contract and its attachments.

A thorough review will give you a fresh recollection of the changes you've made along the way and will facilitate the next step of actually putting pen to paper.

If you and the other side have already agreed to all the changes and it's just a matter of combining these changes, then you can probably complete this whole process on your own. But if you run into any disagreements or some amendments conflict with each other, consider talking to a business attorney. They can handle any negotiations, revisions, or restatements of your business contracts. You might also want to consider involving a lawyer sooner rather than later if the contract is complex, includes regulatory requirements or industry-specific regulations, or is applicable across multiple jurisdictions.

2. Fully Merge All Existing Terms Into the New Contract

When you're prepared to draft the A&R Agreement, start with the original document and then modify it with every change described in each successive amendment.

Make sure your A&R agreement includes the following:

  • You must add the phrase "Amended and Restated" to the title of the A&R Agreement in all relevant places.
  • The recitals to the A&R Agreement should describe and define the original agreement (including the background, date, and original parties) and further describe the evolution of each iteration of the amendment process through the present day.

Admittedly, this task can be painstaking and result in the modification, addition, or removal of various provisions multiple times (depending on the number and scope of the existing amendments). But this process is the only way to ensure that your final product properly reflects the agreement as it exists to date, in one document.

3. Add New Terms to the Contract

Now you should have one consolidated document that properly reflects all of the terms and conditions the parties have agreed to thus far, pursuant to the prior amendments. Your next task is to modify your draft of the A&R Agreement to incorporate the newest changes that the parties have agreed to. You might need to modify an existing clause or add a new one.

4. Add an Integration Clause

At this point, you should have a draft of a fully updated A&R Agreement that represents all of the current understandings of the parties. The intent of creating an A&R Agreement is to fully repeal and replace the prior agreement, which should be rendered completely null and void. To clearly communicate that the A&R Agreement in its entirety is the new agreement and that any prior agreements or amendments should now be ignored, you should add an integration clause as the very last section of the A&R Agreement.

Here's an example of an integration clause:

Entire Agreement. This Agreement, including all exhibits and appendices hereto, embodies the entire agreement and understanding of the parties hereto in respect of the transactions contem­plated by this Agreement and supersedes all prior agreements, contracts, representations, warranties, promises, covenants, arrangements, communications, and understandings, oral or written, express or implied, between or among the parties with respect to the subject matter hereof, including, without limitation, the Original Agreement, which Original Agreement shall be deemed null and void, and of no further force or effect whatsoever following the date hereof.

You should include this clause at the end of your agreement as part of the contract's boilerplate provisions.

5. Finalize the A&R Agreement

Now that you have a fully-drafted A&R Agreement hot off the press, you can share it with the other parties for their review and approval. Ideally, you'll facilitate everyone's review of the new document by providing them with a redlined markup of the document.

You can use document comparison software to create redline and blackline versions of the A&R agreement. Typically, the redline version will show which text has been deleted, changed, or added to the original document. The blackline version will show the contract with these changes already implemented.

For example, in Microsoft Word, you can use the "track changes" feature to show a redlined version of your contract. You can also use "legal blackline" or "compare documents" to compare the original contract with your version of the A&R agreement. Alternatively, Google Docs has "suggest edits" for redlining along with its own "compare documents" feature.

These electronic comparison tools are commonplace. They provide accurate and detailed tracking so all parties can know who made what changes.

The markup should clearly reflect all of the differences between the original agreement and the A&R Agreement. This step will be appreciated by all parties involved because it eliminates much of the guesswork as to how the contract has evolved over time. After you have a version you both agree on, you can sign the new A&R agreement.

Best Practices for Amending and Restating a Contract

As you go through the process of reviewing your original contract and its amendments and combining everything into an A&R agreement, it's best to keep some best practices in mind. These best practices should simplify the process. They should also ensure that your finished product is clear, unambiguous, and legally binding.

Tracking Contract Versions

An A&R agreement should:

  • simplify the appearance of your contract and all of its amendments, and
  • clarify the final terms and conditions of the agreement.

You'll want to keep a careful log of every version of the agreement. Specifically, you should keep track of:

  • when changes were made
  • who made the changes
  • what the changes are, and
  • where the changes appear in the agreement.

Using track changes or another comparison tool will help you see what the changes are and where they appear in the agreement. These tools will also usually track when changes are made and by whom. But as you exchange your changes and versions of the agreement with the other party, it's best to label each version you create.

When you email your version of the agreement to the other party, you can include this kind of information in the file name. For example, you might name your file "AH_10102025_v1." That file name includes the initials of who made the changes (AH), the date of the change (10/10/2025), and the version number (v1). You might get a file back labeled "GL_10142025_v2" that includes their initials, the date, and the version number.

Using Electronic or Digital Signatures

So many contracts are signed via electronic signature these days. Electronic signatures are widely accepted and considered legally binding. They're typically easier and quicker than traditional, handwritten signatures.

Oftentimes, businesses use digital signature software like Adobe or DocuSign for contracts. These software programs usually list out the name of the signer and the date of the signature. But you can also electronically sign your name without special digital signature software.

While electronic signatures are widely accepted for most contracts, it can be a good idea to insert a provision in your A&R agreement that specifies that both parties accept digital signatures as valid and binding.

Here's an example of an electronic signature clause:

Electronic Signatures. The parties hereby agree that this Amended and Restated Agreement, and any documents connected herewith, may be executed and delivered by electronic signature. A party's electronic signature will carry and hold the same legal effect, validity, and enforceability as the party's original signature. A party's signature, electronic or original, indicates the party's intention to be bound by the terms and conditions under this Amended and Restated Agreement.

Amended and Restated Agreement Example

Below is a sample introductory paragraph for your A&R agreement. After you draft the introductory, you can insert the A&R agreement with all of the amendments incorporated.

WHEREAS, the Parties entered into that certain [Name of Original Agreement], dated as of [_______________, 20__], for the purposes of [___________________________] (the "Original Agreement");

WHEREAS, the Parties entered into that certain First Amendment to [Name of Original Agreement], dated as of [_______________, 20__] (the "First Amendment");

WHEREAS, the Parties entered into that certain Second Amendment to [Name of Original Agreement], dated as of [_______________, 20__] (the "Second Amendment");

WHEREAS, the Parties entered into that certain Third Amendment to [Name of Original Agreement], dated as of [_______________, 20__] (the "Third Amendment", and together with the First Amendment and the Second Amendment, the "Amendments");

WHEREAS, the Parties desire to amend and restate the Original Agreement in its entirety, together with all Amendments; and

NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, the receipt and sufficiency of which is hereby acknowledged, the Parties hereto agree as follows:
