Change and termination of contractual agreements
Although terms and conditions are an extremely valuable tool which can be
used to set the foundations for any commercial arrangement, in the case of
long-standing business relationships such as those involving ongoing supply
of goods or services contracts for manufacture or resale, there will come a
time when the terms of an agreement will need to be changed or updated or
the agreement itself may need to be concluded. It’s important to know the
best ways to vary terms, amend a contract or bring it to an end, so that
your business interests are protected.
Changing a contract
If you wish to vary the terms and conditions of a long-standing business
agreement, such as that for the supply of goods or services, it’s important
to ensure that any changes are agreed to by both parties and that this

If your business is being sold, you can use a novation letter for sales or
purchases to ensure that your contracts with customers and/or suppliers are
successfully transferred to the purchaser.
Terminating a contract
It may become necessary to bring an ongoing contractual agreement for the
supply of goods or services to an end, either as a result of financial
considerations or because you are forging a new business relationship or
bringing things in-house. Whatever the reason for terminating a contract,
it’s important to comply with any notice period to which you have agreed.
You may decide to bring the contract to an end unilaterally using a
termination letter but in certain situations it may be better to use a
mutual cancellation or release document, particularly if a handover of
duties is necessary.
