~ David H., California. I found your online divorce service exceptionally easy to use. As a point of reference, our California divorce took less than three weeks and including your fees and San Francisco County's filing fee of $370, and notary fees, the whole process cost us less than $800. We were very pleased with you question and answer method and breezed right through it.
This does not include the courthouse filing charges, which might vary from county to county. Filing charges may cost a few hundred dollars. There are many forms required for a California divorce. While it is a no-fault state, the California divorce process can be complicated, even when there are no disagreements between parties.
