Chapter III: Just Compensation
As of what date will my property be valued?
When property is appraised, the appraiser must provide an opinion of value as of a particular date. California law provides several possible dates of value, depending on the circumstances of the particular case.
In most cases, the date of value will be the date the government makes a deposit of probable compensation into court. Alternative dates are either the date the eminent domain complaint is filed in court, or the date of trial.
Which particular date applies in your case will depend on the specific facts of your case.
