Private Detective | Marin County

Aal & Associates is a leading private detective company serving clients in Marin County, Tiburon, Mill Valley, Ross, Belvedere, San Francisco and surrounding areas of California. The first step we take is to understand your needs so we can design an investigative plan that will deliver the best results within your budget and timeframe. Consultations for new client are always provided at no charge.

Complete Transparency: Agreement of Services Document

We then create an Agreement of Services document outlining the investigative services discussed during the free consultation. The agreement clearly states the cost of our services and the initial retainer amount required before we can start your investigation. After reviewing the agreement, simply return the signed document to our office via fax, email or U.S. mail. Payment options can be found on our “Payment” page of our website as well as on the last page of the Agreement for Services document. Our commitment to honesty, integrity and fairness applies to every aspect of our investigative services and billing practices.

The Investigation

We will not accept your case unless we have the experience, investigative skills, and required equipment to effectively resolve your case. We are professional, passionate investigators committed to producing quality results in every case.

The Product

Our reports to our client are our product. We take great care in addressing the individual issues raised in each case. Our reports are captioned according to the information required by the client.
