~ 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.
Now, you must take the packet home, and read it. Use the instructions to create your petition for divorce. Make sure that your petition is properly filled out because once you pay to file the divorce (between $272 and $329), the filing fee is non-refundable with Bexar County. For a good sample of what a common petition for divorce looks like, see this link.
