50+ Sample Amendment Contracts

What are Amendment Contracts?

An amendment contract allows one or both signatories of a contract to make changes, remove clauses, or add conditions to an already existing contract. In other words, following the contract amendment definition, allows the parties to make mutually agreed upon changes while the original contract remains in place, but only with some terms altered through amendment.

Keep in mind that an amendment contract is only possible when the contract has already been signed and notarized by both parties. Any changes made during the negotiation process are not considered amendments since there is no existing contract yet. It simply means negotiating the original terms.

A contract can be amended any time one of the parties wants to make changes to the terms, conditions, clauses, and definitions in the existing contract. These changes should be discussed by both parties and should also be agreed upon.

One party must write up these changes and both have to sign them. Another possible scenario is to send an amendment contract with a letter that explains why certain alterations or changes have to be made in the contract and the other party can decide whether to agree to it or propose changes of their own accord.

Contract amendments are also useful in cases where you and the other party have ended up handling matters differently than the contract requires. You can no longer do so, it’s a good idea to update the contract to reflect that change in practice.

Ways to Make an Amendment Contract

When changes in the existing contract have been approved by both parties, it’s now time to make it official. There are several ways to amend a contract:

Amendment Contract Letter. You can use a contract amendment letter to list down all the changes you wish to make to the original document and both parties should agree to it and sign for confirmation. Amendment Contract Template. The amendment contract can be created through a contract amendment template.

Adding amendment pages to the existing contract is also possible. It can either be through digital, print, or both to the end of the original signed contract.

How to Create Amendment Contracts

Once all parties involved agree to the changes in the current contract, an amendment to contracts doesn’t have to be as formal as the existing contract. It can take on many forms—a letter, using a template, or even following the layout of the original contract. It does not have a specific requirement that the modifications made should follow a standard format. However, for significant changes, you may follow these simple steps below:

Step 1: Review Existing Contract for Amendment Clauses

Typically, contracts contain clauses that state how the contract should be amended. It should describe the ways in how the signatories can modify the existing agreement and under what terms it should be allowed to change. Many contracts require that any amendments (e.g. amendment to the rental template or in a lease amendment to add tenant), be made in writing, agreed upon, and signed by both parties.

Step 2: Create a New Document

The goal of an amendment contract, regardless if it’s for a residential lease extension amendment or an amendment to purchase agreement, is not to replace the original contract, but to outline any changes, alterations, and modifications made to it. Creating a new document will allow you to define all the changes made to amend agreements in the original document. These changes can be about:

Step 3: Title and Date of the Document

The current date of the amendment contract, the title of the document, and the date of the original agreement should reflect in the new document. It’s important to add these details to avoid confusion and for easy tracking should there be any misunderstanding and miscommunications.

Step 4: Specify all Modifications Made

Any changes, alterations, and modifications of the original contract should be described in the new amendment document that was just created. Make sure that the final document is specific and concise and will only pertain to the sections being amended.

Step 5: State the Reference Sections for Replacement and Disclaimer

In your amendment contract, do not forget to summarize the changes by stating the referenced sections, clauses, conditions, and definitions in the new contract. This will help make the document easily enforceable and carried out by both parties in the agreement. It should also be stated that only the following changes, modifications, and alterations are accepted and the original one remains, otherwise specified.

Step 6: Sign on the Agreed Changes

After both parties have agreed to the changes in the amendment contract, they should sign the document to make it official. If any more changes will happen after signing, new amendment contracts should be created. This will guarantee the legal validity of the amendment contracts.

How to Amend a Contract

When modifying existing contracts, it does not have to be formal. But it can be done in several ways. For minor changes, handwritten changes in the contract are acceptable as long as all parties involved and signatories agree to it and make their initials and the date next to the alterations in the contract. However, significant changes in the original business contract should be done in three general ways:

Each one of these types of amending the contract will usually be valid under the law as long as all parties involved are in agreement with these changes. Remember that these changes are only acceptable if both signatories of the contract make initial and include the date of these amendments.

Common Types of Amendment Contracts

Although most contracts have an amendment clause that states the conditions in which a contract can be amended, there are many instances where it can also be changed even when not specified in the said clause. Some of the most common situations where you might need to amend a contract include:

Terms. This could refer to extension or shorten the length of the contract, thus clearly extending or cutting short the validity of the terms of service in the contract.

Fees. It is typical for prices to go up or down. But in some cases, when the changes in prices are fluctuating heavily, it may also require changes in the contract to reflect these fluctuations and justify an increase or decrease in fees.

Liabilities. Often, these changes are made because of unforeseen circumstances or unprecedented events that both parties experience and made them unable to honor their responsibilities.

Time periods. Most of the time, this refers to delivery or shipment times. It can either be to extend or shorten the time period based on the experience of both parties to execute the action.

Best Practices for Contract Amendments

It’s a no-brainer that when amending a contract, it should be clearly defined in the document which sections are to be modified, which portions are to be struck, which definitions are to be updated, and which clauses are to be added to the original contract. But no matter how diligent you are in making these changes, it doesn’t hurt to follow these tips when creating a contract amendment to make sure that it’s complete and everything is clear:


What are the differences between an amendment, an addendum, and an appendix?

Although they may all seem similar to each other, there are key differences among them. An amendment changes the terms, sections, clauses, and definitions in the original contract; an Addendum keeps all original contract conditions in place and just adds new ones. The appendix usually appears at the end of a contract—they don’t affect the existing contract in any way and it only provides extra information or explains certain words.

When can contracts be amended?

Most contracts have an amendment clause where it specifies how and under what conditions and situations they should and can be amended. Typically, only signed contracts can be amended through the different methods described earlier. Any changes to an unsigned contract are not considered amendments, rather the process is called negotiating the terms.

Is it necessary to put amendments in writing?

Yes. It’s always a smart idea to put everything in writing especially when it concerns business and legal transactions. In a court of law, written agreements and documents often bear more weight than oral agreements.

Why should a contract be amended?

There are many reasons why contracts are amended. It can be because a provision was forgotten to include in the original contract, conditions have changed in the course of the contract, or because of unprecedented and unforeseen situations.

When a signed contract or agreement changes, putting it in writing is always a good idea. An amendment contract can help you make adjustments to your original contract’s certain sections, terms, clauses, and definitions without revoking the entire provision of the document. Just make sure that you include all the necessary information such as the name of the original being amended, the changes that are being made and to which sections, and the effective date of the amendment. It’s a time-saving process because you don’t need to start from scratch and keeps things from getting confusing when potential questions arise.
