James Duberg Attorney At Law on Chula Vista's Third Avenue has concentrated on estate planning, probate, and trust administration since the practice's founding in 1977 in the Third Avenue Village district. The firm's trust-funding workflow includes retitling real property into revocable living trusts via grant deeds, a process that often runs in parallel with title searches and property-management coordination through firms such as Teigerhomes Real Estate & Mgmt. in Chula Vista. Nearly five decades of practice have built a caseload encompassing wills, powers of attorney, advance healthcare directives, elder law guardianships, real estate transactions, and small-business entity formation for entrepreneurs along the Third Avenue and Broadway corridors. Trust administration and probate proceedings often require asset-valuation reporting coordinated with enrolled agents and bookkeepers such as 360 Bookkeeping + Tax Solutions to prepare fiduciary accountings and final estate tax returns. The practice's highest-complexity matters involve contested conservatorship petitions under California Probate Code § 1800 and multi-beneficiary trust disputes requiring forensic tracing of distributions across commingled investment accounts.
