The issue of the inadmissibility of negotiations and “spousal privilege” are like apples and oranges. There is a general premise that settlement discussions are not admissible for the purposes of proving potential liability. Therefore, you cannot use in court a statement by your spouse that he or she was willing to take X dollars when you were negotiating, to help to support your position on an issue. The purpose is to encourage people to engage in settlement discussions without worrying that such statements may be used against them in court.
The “spousal privilege,” however, is a different subject and usually does not apply in family-law cases.
Generally, California divorce law allows one party not to testify to the detriment of the other spouse when the latter is involved in a lawsuit. The “privilege” of not testifying against your spouse clearly has a major exception. In a proceeding brought by or on behalf of one spouse against the other, there is no marital privilege. Therefore, one spouse testifies in a dissolution proceeding against the other spouse. Even communications between the spouses during the marriage are admissible.
Negotiations may be inadmissible in the dissolution proceedings when determining the issue of your divorce attorney’s fees. The court can look at the negotiation positions of the parties pursuant to Family Code #271.
