Provided the errors are identified before the trust undertakes any substantive activities (for example nothing more than establishing a bank account), the trust should be vested and a new trust with the correct terms established. This approach will generally be far simpler and more cost effective than attempting to rectify the error in the existing trust instrument and will simplify future dealings with third parties such as financiers.
If the trust has acquired assets or undertaken activities, please contact us and we can provide a suggested scope of work and fixed pricing to assist.
