You will need to create a list of all of the property, debts, bills, retirement, pension, stocks, and anything else to two of you acquired during the marriage. This will assist in dividing the property.
You will also need to get your last couple of year tax returns and any current pay stubs so financial orders can be made.
The general rule is to bring everything you can think of because Murphy's Law states that what you do not bring is what you need. A little over kill does not hurt anything.
An excellent way to prepare for your initial meeting is to fill out a Schedule of Assets and Debts. You can find the form here: http://courts.ca.gov/documents/fl142.pdf
You should also locate any premarital or postnuptial agreements and should bring them to the meeting.
Your new lawyer will be impressed by your level of organization. - http://richarddwyer.com, mountain view
