Overview
Ozgun Tumer and Omar Sharif founded their Costa Mesa law firm to serve the legal needs of the business community, and both founding partners bring entrepreneurial backgrounds to that work. Tumer holds three degrees from two of the country’s academically rigorous institutions: a dual Bachelor’s in Economics and History from the University of Chicago in 1996, a J.D. from University of Michigan Law School in 1999, and an LL.M. in Tax Law from Chapman University School of Law in 2013. That accumulation of credentials across economics, law, and tax is not accidental. It reflects a practice orientation that is simultaneously commercially minded and technically deep in tax.
Tumer & Sharif Attorneys at Law operates from Suite 208 at 170 East 17th Street, Costa Mesa, California 92627. The firm’s website is www.tumersharif.com/. It holds a 5-star Yelp rating and has been featured on the Handel on the Law radio program, where Ozgun Tumer was identified as the best business law attorney in Costa Mesa. The firm serves clients across Orange County, the Inland Empire, and Los Angeles County.
Practice Areas
Business Law: The firm’s foundational practice area covers the full lifecycle of business legal needs: employment law compliance, contracts, trademarks, advertising law, insurance disputes, leases, partnership structures, business disputes, and litigation when resolution through negotiation is not possible. The firm’s service area for business matters extends beyond Costa Mesa to include Orange County, the Inland Empire, and Los Angeles County. Both founding partners describe themselves as attorneys with entrepreneurial spirits who understand the motivations and pressures that business owners face.
Tax Law: Ozgun Tumer heads the tax law department. With a Michigan J.D. and a Chapman LL.M. in Tax Law, he brings formal post-J.D. tax education to the firm’s business and personal tax practice. The tax practice addresses both business and personal tax matters, and IRS representation is within the firm’s scope based on the nature of the practice. Tax and business law are treated as integrated disciplines at this firm rather than separate departments.
Estate Planning and Wills: The firm handles the full spectrum of will types: Simple Wills, Pour Over Wills, Couple Wills, Conditional Wills, and Advanced Directives. Trusts are drafted for probate avoidance and tax savings, consistent with the firm’s tax-oriented approach to planning. The estate planning practice is informed by the same tax analysis that underlies the business law and tax practices, which is particularly relevant for business owners whose largest asset is their company.
Asset Protection: Asset protection work is integrated with estate planning at the firm. The goal is to protect a client’s estate from tax exposure and maximize the value passed to loved ones, while balancing asset protection objectives with estate planning goals. Business owners who have built significant value in their companies often have specific asset protection needs that differ from those of clients with primarily personal assets.
ADA Lawsuits: The firm is listed on Yelp as handling ADA-related matters. Specific detail about this practice area is not publicly available beyond its listing.

Frequently Asked Questions
What is an LL.M. in Tax Law and how does it differ from a standard law degree?
A standard J.D. provides the legal training required to be admitted to the bar and to practice law across a broad range of matters. An LL.M. in Tax Law is earned after completing the J.D. and requires a full additional year of graduate legal education focused specifically on taxation. Ozgun Tumer completed his tax LL.M. at Chapman University School of Law in 2013, roughly 14 years after earning his Michigan J.D. For clients with business tax planning needs, estate tax questions, or IRS representation matters, that sustained formal engagement with tax law at the graduate level shapes the technical depth of the analysis applied to their matters.
Can the firm help with both my business contracts and my estate plan?
Yes. The firm handles business law, tax law, and estate planning as integrated practices. This is particularly relevant for business owners whose estate plans must account for business succession, which has both legal and tax dimensions. Clients who have both business legal needs and personal estate planning needs can address both with the same attorneys.
What types of wills does the firm draft?
The firm drafts Simple Wills for straightforward asset distribution, Pour Over Wills designed to work with trusts, Couple Wills for married couples with coordinated distribution goals, Conditional Wills that place conditions on bequests, and Advanced Directives covering healthcare decision-making. The appropriate type depends on each client’s family situation and goals.

The firm is listed as handling ADA matters in its Yelp profile. Prospective clients with ADA-related questions are encouraged to contact the firm directly at www.tumersharif.com/ for information about the scope of services in this area.
