The DIY Residential Tenancy Agreement (E-Paket) E-Pack aims to help the public enter into an independent lease agreement for their homes without the expense and efforts of a lawyer. However, if an amendment is so substantial that it changes the nature of the lease, it may be desirable for the parties to enter into a new agreement to avoid confusion. For example, if the term of a lease is extended, a new lease is effectively created and the parties must, if necessary, enter into a new contract and meet the necessary legal requirements under a new contract. If the rent is increased, stamp duty is also counted. The number of possible legal consequences is as infinite as the number of possible changes. Parties should therefore seek legal advice before committing to amend it. .
