You may have no reason to be concerned that your ex may try to hide assets or take any other actions that could harm your interests. But there are still steps that you should take to protect your assets and start putting yourself on firm financial footing for the future.
For example, one key step you need to take early on is gather information. This means getting your account numbers and passwords together and making copies of account statements.
You should also make copies of your important documents and do an inventory of the objects you have in your house. And if you have a prenuptial agreement, it's time to review what it says.
