Board-certified by the California Board of Legal Specialization in estate planning, trust, and probate law, Ewin Lambourne Law, APC in La Mesa Village has practiced from La Mesa Boulevard since the mid-1980s. Life-insurance trust planning integrates with comprehensive estate packages, requiring coordination between the firm and policy carriers such as Mashkoory Insurance Agency to ensure beneficiary designations align with trust provisions. The practice handles living-trust creation, probate administration, conservatorship petitions, and pour-over wills, with an attorney also serving as a court-appointed guardian ad litem for San Diego Superior Court proceedings. Estate and trust tax obligations — including California Franchise Tax Board fiduciary-income reporting — often require parallel preparation by accounting firms like Abbo Tax CPA during trust-administration settlement. Highest-complexity engagements involve contested-trust litigation and Heggstad petitions to confirm assets into a decedent's trust when formal transfer documents were never executed.
