What is a Letter of Demand?

A letter of demand is a formal correspondence sent by one party to the debtor party requesting for payment or other specific actions based on a right that has been breached.

You may write a Letter of Demand and send it to the person or company who owes you money. This is done when it has taken a long time already for the debtor to pay you. The letter of demand serves as the reminder or the warning letter for that debtor to give you the money.

In addition, writing a letter of demand enforces the right of the construction service providers to demand for payment in accordance with the Security of Payment Act. It gives the person owed an easy and inexpensive way to demand for his payment.

In which situation can you use a Letter of Demand?

Letters of demand are used to recover payment in different situations and not just in the construction industry. It can be used to recover unpaid wages, invoices, rents, loans, and deposits. But in the context of contractor/business owner, the situation could be illustrated as something like the example below:

Kenny is a 40-year-old subcontractor based in Sydney. He received a call from a business owner (Owner) who urgently needs him to fix his electricals. They both discussed the problem and came up with an agreement on resolving it. Kenny told his client about the price which also includes the expenses for extra materials needed to fix the electricals. The Owner agreed as he is desperate to have his electricals fixed immediately. The parties also agreed on the due date for the Owner to pay Kenny.

Kenny did everything he can to get the electricals fixed quickly. He was able to finish the works properly and correctly. However, when the due date for the payment came, he did not receive anything from the Owner. He called up the Owner and he was promised that he would get paid the following week. Kenny agreed and waited until next week. But when the time for payment came again, Kenny did not receive anything. He phoned his client again but this time, he could no longer reach him. Kenny then decided to go to his client personally. He was told the same promise of getting paid again but it never happened.

It is in this situation that a letter of demand can now come into the picture for Kenny to enforce his right to demand payment from the business owner.

  • Your full name
  • The date
  • Your contact details (so the debtor would know how to send the payment to you or how to reach you for a possible negotiation)
  • The name of the owner and his/her business address
  • The works agreed and the works accomplished
  • The amount of money that they owe you
  • Invoice details
  • The due date you will set to receive your payment
  • How they can pay the money (through bank or in cash) or payment details
  • Evidence to support the right to demand payment to be attached on the letter of demand

TIP: When you send your letter to your debtor, make sure that you keep a proof that you have mailed your letter. This could be evidence you can use in case the situation escalates into a legal dispute.

What is the Importance of a Letter of Demand?

Your client may not realise how much money they owe you. In some instances, they may have forgotten it or has a different reason for not being able to pay immediately. Thus, a letter of demand lets your client know how much they need to pay you.

For legal reasons, this could serve as solid proof that you tried recovering your money from your client. This could be an immediate resort for contractors, subcontractors, and suppliers before even deciding to take their case to the court. It is also advisable that two or three letters of demand are sent before taking legal action.
