"I contracted Alen for a commercial lease review. I couldn't be happier with the results, as he exceeded my expectations. He completed the project 2 days ahead of the estimated timeframe, gave me high quality feedback, and suggested alternate language. We had a call at the end and he answered all of my questions in detail. Incredible value. I'm so happy I chose Alen, and I definitely recommend him to anyone else needing legal assistance."

Prenuptial Agreements I represent clients in the preparation and review of prenuptial agreements. My experience includes drafting comprehensive prenuptial agreements on behalf of the initiating fiancé, ensuring that the agreement accurately reflects the client's financial interests, assets, liabilities, and objectives while complying with applicable legal requirements. I also represent the non-drafting fiancé by conducting a thorough review of proposed prenuptial agreements, identifying legal and financial issues, explaining the rights and obligations created by the agreement, recommending revisions where appropriate, and negotiating modifications to help protect my client's interests before execution. Probate Administration Represented a client in the complete administration of a California probate estate valued at approximately $1 million. Successfully handled the matter from the initial petition through final distribution, preparing all required court filings, advising the executor throughout the administration, resolving probate requirements, and obtaining court approval to close the estate. Achieved the successful distribution of the estate assets to the executor and sole beneficiary in accordance with California probate law.

Before law school I built the contract management system for a publicly traded medical device company — so I read your agreement the way the people who have to live with it will, not just the way a court would. I draft and review business contracts on a fixed fee, with the delivery date agreed before I start. You get the redlined document plus a short written summary of what I changed, why it matters, and what I'd push back on if the other side objects. Revisions are included — I'd rather get the document right than count rounds. NDAs, MSAs and SOWs, contractor and employment agreements, SaaS terms, terms of service and privacy policies, operating agreements, vendor and construction contracts, and full contract review with a plain-English risk summary. Send me the document and what you're trying to accomplish with it, and I'll come back with a fixed fee and a date.
