My name is Costin Harnoncourt, and I am a commissioned California Notary Public serving clients in and around Los Angeles, CA. Through my business, Notary By Car, I focus on providing convenient, reliable mobile notary services brought directly to you.

I work with individuals, families, and businesses to help ensure their important documents are properly notarized and executed. I am fluent in Italian and Romanian, which allows me to assist a wider range of clients and help bridge language gaps during the notarization process.

My goal is to offer a professional, efficient, and friendly experience every time, whether you need a single document notarized or ongoing support. I look forward to helping you complete your notarizations smoothly and with confidence.
