O'Connor has served individuals, families, and seniors throughout Orange County since 1994. Operated by attorney Mark L. O'Connor, the firm provides a comfortable atmosphere where legal concepts are explained clearly so clients feel confident in every decision.

A graduate of California State University, Fullerton and Whittier College School of Law, Mark L.

Core Areas of Estate and Trust Practice

As dedicated wills, estate planning and probate lawyers, the firm delivers tailored legal guidance across all essential aspects of California asset preservation:

Comprehensive Living Trusts and Revocable Trusts

Avoiding the costly California probate court system is a primary goal for many homeowners. Serving as experienced trusts lawyers, attorney O'Connor designs custom revocable living trusts that allow assets to transfer seamlessly to beneficiaries without court intervention. In addition, the firm structures irrevocable trusts and life insurance trusts to address asset protection and tax objectives.

Last Wills and Testaments

A properly drafted will is a fundamental cornerstone of any estate plan, particularly for families with minor children or dependents with special needs. Functioning as skilled wills lawyers, the practice prepares last wills and testaments, pour-over wills that coordinate with living trusts, and guardian designations, ensuring your children are cared for by trusted guardians and your wishes are legally enforceable.

Durable Powers of Attorney and Incapacity Planning

Estate planning is not merely concerned with what happens after death; it also protects you during your lifetime if unexpected illness or disability occurs. Working as dependable power of attorney lawyers, attorney O'Connor drafts statutory durable powers of attorney, general powers of attorney, and limited powers of attorney, granting trusted representatives legal authority to manage banking, property, and business affairs without expensive court conservatorships.

Advance Health Care Directives

Medical emergencies can leave individuals unable to communicate their treatment preferences to doctors and hospitals. The firm prepares thorough advance health care directives and living wills that articulate your end-of-life decisions, nominate healthcare agents, and ensure your personal values and medical preferences are strictly respected by healthcare providers.

Trust Administration and Guidance for Successor Trustees

When a trust creator passes away, successor trustees face important legal and financial responsibilities under California trust law. Functioning as supportive probate lawyers and estate planning lawyers, the firm assists trustees with beneficiary notifications, asset valuations, debt settlements, and final distributions, guiding families through the administration process smoothly and compassionately.
