Parties to the divorce should try and agree the division of assets in a non- confrontational matter at first instance. This can be done by having solicitors assist you through round table discussions or mediation.
The starting point is a 50/50 division of assets, but there are further considerations which may affect the final division of assets. Once an agreement is reached, it should be formalised in writing after legal advice has been obtained on this. If an agreement is not in writing and not approved by a judge, it will not be binding.
Once an agreement has been approved and finalised, it is very rare that the court will agree to it being re-opened unless something later happens that alters the principle on which a consent order was made.
