A purchase agreement is a legal document that is created and executed by the parties in many real estate and commercial transactions. The purchase agreement is intended to reflect the intentions of the parties with regard to the sale. The agreement will usually include details such as the purchase price and form of payment. Occasionally the parties may need to change something in the agreement after they have executed, or signed, the agreement. In that case, the parties may execute an amended purchase agreement
Consult with the other party to the purchase agreement regarding what changes you wish to make to the original agreement. Draft the language that you plan to add or change in the agreement, or decide what language you will be deleting.
Title the new document "Amendment to Purchase Agreement." Begin the document by stating who the parties are to the agreement and referencing the original agreement, including the date of the original agreement.
State specifically in the body of the amended agreement exactly how the parties want to amend the original agreement. For example, "Paragraph Two shall be amended to read 'the purchase price shall be paid in three equal installments' as agreed by the parties."
Create signature lines for all parties involved. Have each party sign the amended purchase agreement in front of a notary public.
Attach the original purchase agreement to the amended purchase agreement so that it is incorporated into the new agreement.
