Legal Question in Family Law in California

Values of things have little or no role in establishing child and spousal support. For property distribution, values are mostly determined at the time of distribution, which in the case of a negotiated distribution would be at the time the agreement is negotiated. Exceptions would be for things that have accumulated more value due to additional contributions of earnings after separation, such as pension and 401k accounts, because earnings after separation are separate property. There may be other situation specific exceptions, but most commonly it is time of agreement/distribution that is used for valuations.
