Representative Experience

  • Represented a party in a divorce action that settled once the client’s interest in a family trust created by client’s father was excluded from the marital estate and assets previously transferred by the parties to an irrevocable trust for the benefit of their children were excluded from the martial estate.
  • Represented a party in an arbitrated divorce action in which the opposing party’s claim for child support was denied because the parties’ premarital agreement included a mutual waiver of alimony and each party’s Separate Property was sufficient for the children’s support while they were in the care of each party.
  • Represented a party in an arbitrated divorce action in which the funds entrusted to the client’s care for the benefit of the client’s siblings and the parties’ child were excluded from the marital estate and the opposing party’s interest in a closely-held high tech business was held to be the value determined by the client’s appraiser.
  • Represented a party in a divorce action that settled when the validity and enforceability of the prenuptial agreement was called into question because counsel for the opposing party had made certain revisions to the agreement that were not reviewed by client’s counsel prior to signing.
