Law Reform (Testamentary Promises) Act 1949, s 3
Anyone can make a claim under the Law Reform (Testamentary Promises) Act 1949 if you have promised to leave that person something in your will in return for services rendered or work done, and you have not kept that promise. For example, the person may have taken care of you when you were ill or looked after your property, and in return you may have promised to provide for the person in your will.
It may not be necessary to prove that a promise was made expressly. The court may be prepared to infer from the surrounding circumstances that there was a promise.
Note: It can sometimes be difficult to prove that a promise was made. Evidence can be oral or written; for example, letters. Previous wills can also be evidence of the will-maker’s intentions.
