It may be important to keep your pre-nup under review. It may well specify in it that the agreement needs to be looked at every few years or if there any changes in circumstances – for example, if you have a child or if one of you falls ill. Reviewing the pre-nup is likely to be an effective way of ensuring that the agreement is likely to stand up when it needs to. This makes the agreement more flexible and able to adapt to the unexpected twists and turns which can happen in life but which could not be predicted when you first entered into the pre-nup.
