A: It might depend on the facts of your case, but using pleading paper is generally in any type of California state court civil case. You can make your own pleading paper in Microsoft Word or other similar word processing program. You can download Word templates for pleading paper. Here's one from the California court website (https://www.courts.ca.gov/selfhelp-forms.htm?rdeLocaleAttr=en). Scroll all the way to the bottom.
A: I would be very surprised if the clause you quoted referred to something besides accounts and contributions made during the marriage. In California, accounts and contributions made prior to the marriage are separate property and the other spouse wouldn't be making a claim for separate property anyway. Thus, your clause would be superfluous if it referred to pre-marriage accounts and contributions. In California, contributions made during the marriage are community property by default (i.e. it would be split in a divorce), but it is very common to change this in a prenup. A clause like the one you quoted would be one way of doing that. As a result of a clause like yours, the spouses would have no claim to each other's retirement plans.
A: I agree with Mr. Gribow. It's a common misconception that you will are guaranteed to receive a benefit if you hire your own lawyer versus representing yourself or using the public defender. Each lawyer has their own experience and perspective which might cause the lawyer you hire to have a new idea no one else has thought of before. However, no lawyer is a magician. Ultimately, it boils down to the facts of the case and what evidence the prosecutor has versus what evidence the defendant has.
