What happens if full disclosure is not given?
Should you fail to give proper disclosure, then it may be possible for the other side to ask the Court to set aside the settlement (usually at your cost) and to give them more money. If you are found to have lied about some of your finances, you may also find you will not be believed on the rest of your finances as well, which usually means it will cost you a lot more money.
If there is non-disclosure it has to be shown to have been material, before the Court will consider changing any Order. This means it would have had to make a difference. The more speculative the information, the less likely it may have an impact. You also have to consider timing. If you are in delicate negotiations about a new job, for example, you can hold back on resolving the financial issues until you have reached an agreement on this and then can give disclosure.
